Electricity usage costs have become an increasing fraction of the total cost of ownership (TCO) for industrial pumping systems. In fact, energy cost represents 40% of the TCO of a typical pump. It is possible to reduce the electrical consumption by at least 30% through appropriate energy management practices while reducing the maintenance cost. This paper explains how to reduce TCO with a limited investment.

[Oil & Gas White Paper] Gas Day Planning: Managing volatile end of day run-upSchneider Electric
Efficient management of gas day operations involves matching supply to demand, keeping pressure in the pipelines relatively constant and avoiding big swings. The biggest challenge is volatile demand during the day, particularly during its final days, or end-of-day run-up, which combines the greatest volatility with little time to adjust before the end of the day.
Operators already use forecasting models to plan the overall daily delivery, but to best cope with these challenges they need the ability to plan for gas output throughout the day to match hourly swings. By utilizing tailored industry solutions and established best practices, pipeline operators can use accurate forecasting solutions to break down daily demand forecasts into hourly predictions. Using hourly forecasts instead of a flat daily projection better matches actual demand and while small deviations from the forecast will occur, an hour-by-hour system allows pipelines operators to track the accuracy of projections and more easily adjust for unanticipated changes.
These forecasts are not based only on current factors, but rely on historical analysis as well to develop a more accurate prediction of demand. Particularly during the extra-volatile end-of-day run-up, compiling and analyzing historical data on a continual basis provides a rational prediction of demand for any given conditions. Taking these existing tools and data sources, the challenge of managing the end-of-day run-up can be significantly reduced.
Only 8–12% of customers report a power outage to their utility. Utilities that integrate Automated Metering Systems (AMI) data into outage management systems receive faster and more accurate reports about power outages, can better predict the extent of the outage, and more reliably verify service restoration.

The control of energy in non-domestic buildings is generally poor, despite the availability of a range of tried and tested systems incorporating both established and innovative technologies. Although the installation of HVAC zone controls, optimising controllers (for Wet Heating Systems) and lighting controls is encouraged by the building codes, their requirements are basic. As a result, specifications are often limited to the minimum requirements, and superior technologies, such as pre-programmed packaged Building Energy Management Systems (BEMS) and Demand Control Ventilation (DCV), are ignored.
[Oil & Gas White Paper] Best Practices Support Success in the Open Natural Ga...Schneider Electric
Information management tools support responsiveness in today’s complex markets.
The changes throughout the energy supply market that have resulted from business globalization require natural gas transport operators to practice flexibility. Yet they need to keep safety and security their highest priorities in this time of unprecedented change. Reliable gas network information management systems and best practices relating to commodity data are more important than ever to improve or even maintain competitiveness and responsiveness in the open market environment.
One consequence of increasingly complex markets is the growing numbers of gas flow, quantity and quality measurements involved—measurements that are vital to financial accounting and subject to customer transparency. Best practices recommend the operator’s gas measurement analysis system accurately and completely collect data; validate per user-specified rules; properly flag, adjust and estimate data where needed; rigorously identify measurement imbalances and potential errors; and maintain audit reports.
One leading gas transmission company in Europe took advantage of Schneider Electric’s experience in the North American deregulated gas market by implementing a Schneider Electric-created turnkey information management solution to help it comply with liberalization mandated in Europe. The resulting monitoring and automated control system included several advanced applications for meeting customer reporting procedures and processes required by the new mandate. The system fully accepts third-party applications, eliminating costly proprietary enhancements and maintenance needed for it to be reliable for the long term.
The system also provides another best practice for safety and security: real-time, redundant backup of the transmission infrastructure’s main Control Center. Finally, the solution provides logistics capabilities that enable accurate tracking and reporting of allocations and delivery, to separate production and supply from transmission operations.
The information management solution that offers these best practices related to measurement accountability, operational flexibility and security helps the user meet global and open market trends while efficiently satisfying regional or country-specific requirements.
The Metals, Minerals & Mining industry has a resource

little room for uncertainty.
[Oil & Gas White Paper] Optimizing Pipeline Energy ConsumptionSchneider Electric
Effective energy management can benefit the hydrocarbon pipeline operator. Energy consumption costs – the leading expense for most operators – are rising continuously; however, the commitments needed on the part of the operator often impede implementation of energy-saving practices.
Key to effective energy management is the ability to quantify energy consumption accurately at any specific time and its cost and that of drag reducing agent (DR) use. Operators committed to energy management can implement a real-time, system-wide power optimization solution that evaluates the resource efficiency of a steady-state model of the pipeline. This solution will also perform costing runs of alternative configurations, formulated for the next energy cost rate or other ‘what if’ scenarios, in order to find the most energy-efficient alternative that maintains operational safety and integrity. Implementing these alternatives, the operator can save one percent to five percent of energy costs and reduce carbon emissions.
This advanced information management technology makes these costing considerations so practical they can become a routine, real-time operations process. Putting available information to work with this solution can make power optimization extremely realistic and highly rewarding for the company while supporting overall operational security, safety and environmental stewardship.

Slide deck of the webinar presented by John Dirkman on Oct. 23, 2013.
The presence of highly variable renewables and distributed energy resources is rapidly increasing within distribution systems, resulting in the potential for problems like reverse power flow, impact on voltage profile, and more complex protection schemes.
During this webinar, John Dirkman, Senior Director of Smart Grid Strategy & Development at Schneider Electric, explored how an Advanced Distribution Management System (ADMS), combined with an accurate weather forecasting system, can be used to resolve problems and increase benefits of both renewables and distributed energy resources.
Key Learning Objectives:
- Learn how renewables and distributed energy resources can impact an electric distribution system.
- Discover ways to manage and optimize renewables and distributed energy resources using ADMS.
- Integration of an accurate weather forecasting system with ADMS maximizes benefits from renewables.
- Distributed energy resources and demand response are components of microgrids, also managed by ADMS.
The Advanced Distribution Management System – ADMS – brings together distribution management system (DMS), supervisory control and data acquisition (SCADA) and outage management system (OMS) technologies , along with control room applications, on one, secure platform with a single user interface. With this comprehensive mission critical solution, the electric utility can monitor, analyze and control the distribution network to improve the level and quality of service.
At its core is the network model representing the as-operated state and based on the as-built state defined by the geographic information system (GIS). A load flow algorithm responds quickly to data sourced from throughout the network to analyze the balanced, unbalanced and dynamically changing network in real time. Users across the network – operators, dispatchers, management, planning engineers and others – have consistent visualization of model results in geographic, schematic and single-line diagram views. State estimation validates viewed data and estimates non-telemetered points to achieve a complete network representation.
With this accurate network model and a portfolio of robust functionalities, the utility is empowered with continuous, real-time analysis of the operational state of the network that enables self-healing capabilities. Demand can be managed through reduction of technical losses; by forecasting near-term load and applying volt/VAR control for peak shaving; and by securely integrating and managing distributed energy resources, including energy storage, to flatten the daily load curve. These and other options enabled by ADMS are key to managing demand in the face of increasing energy usage, surging energy costs and network infrastructure instability due to aging.
The ADMS represents the evolution of control room technology that will help utilities mobilize to meet increasing consumer demand and environmental obligations and reap many of the benefits all stakeholders expect from their smart grid investments.

Eco-Mode: Benefits and Risks of Energy Saving Modes of UPS OperationSchneider Electric
Many newer UPS systems have an energy-saving operating mode known as "eco-mode" or by some other descriptor. Nevertheless, surveys show that virtually no data centers actually use this mode, because of the known or anticipated side-effects. Unfortunately, the marketing materials for these operating modes do not adequately explain the cost / benefit tradeoffs. This presentation shows that eco-mode provides a reduction of approximately 2% in data center energy consumption and explains the various limitations and concerns that arise from eco-mode use. Situations where these operating modes are recommended and contra-indicated are also described.
A high performance green building is designed for economic and environmental performance over its entire life cycle, considering unique local climate and cultural needs and providing for the health, safety and productivity of its occupants. With continuous care over its life cycle, it minimises energy use, CO2 emissions, and total environmental impacts, and provides ongoing measurable value to building owners, occupants and society.
Impact of Planning Decision Support Tools on Mining Operations ProfitabilitySchneider Electric
Changes in the mining industry business environment are leading to gradual changes in how the supply chain (from ore extraction at the mine to delivery at customer sites) is managed. Global demand is flattening and available supply is increasing. This means that complex planning business models that were developed in an era of supply “push” need to be altered to accommodate a market reality of demand driven “pull”. This white paper introduces a decision support methodology that results in reduced cost, improved throughput, enhanced quality, and increased profit.

The Artful Application of Collaborative Negotiations with ProvidersThomas Tanel
Fortune favors the prepared mind—”luck” in negotiations is actually the result of hard work and good planning. This presentation is for those who seek some collaborative negotiation skills that can be applied for success.
One of your major functions is to negotiate the best terms and price for the materials and services your organization needs to operate. This complex task requires knowledge, tact, superior communication skills, and a solid game
plan!
But few people understand that 90% of all negotiations
take place before the involved parties even get to the bargaining table. Collaboration is “in” and compromise is “out” for successful negotiators.
Learn how to make collaboration one of your best negotiating assets and reduce your anxiety as you assume a negotiation comfort level.
The Art of Planning and Writing Specifications and Requirements Thomas Tanel
One of the most difficult tasks that purchasers face is converting user or internal customer needs to new specifications and requirements. For most, it’s easier said than done, while others simply dread the thought of constructing a Statement of Work. Failure to develop a properly defined scope of work, specification, or requirement may mean the solicitation will need to be abandoned and repeated with corrections. Purchasers who are involved in putting together specifications, requirements, or SOWs need to be aware that it is worth the investment, time, and effort to create a high quality outcome. Thus, it is important that purchasers understand the importance of good specifications and requirements, as well as their contractual and practical significance.
This presentation will offer you practical techniques, tools, and process methods for constructing effective specifications, requirements, and SOWs.
Key areas of focus that will be discussed in this workshop are:
Internal customer or user needs
The importance of a scope of work
SOWs and work requirements
The Statement of Work
Writing specifications and requirements
The Art of Planning and Writing Specs and Requirements--ISM 2010 TanelThomas Tanel
One of the most difficult tasks that purchasers face is converting user or internal
customer needs to new specifications and requirements. For most, it’s easier said than done,
while others simply dread the thought of constructing a Statement of Work. Failure to develop
a properly defined scope of work, specification, or requirement may mean the solicitation will
need to be abandoned and repeated with corrections. Purchasers who are involved in putting
together specifications, requirements, or SOWs need to be aware that it is worth the
investment, time, and effort to create a high quality outcome. Thus, it is important that
purchasers understand the importance of good specifications and requirements, as well as
their contractual and practical significance. This proceeding will offer you practical techniques,
tools, and process methods for constructing effective specifications, requirements, and SOWs.

Count the ways distribution centers add value 2nd--supply chain digital septe...Thomas Tanel
N RESPONSE TO THE “NEW Normal”, the business
landscape has changed fundamentally; tomorrow’s
distribution environment will be different, but no less
rich in possibilities for those who are looking for ways
to add value. With new trends and an “e-volution” in
moving and storing materials comes the inevitable need
to reconceive how we operate our distribution centers
to stay competitive. Outdated philosophies not based
on the “New Normal” may prevent us from recognizing
and integrating some of the new ways the distribution
facility or DC can add real value to our operations.

For purchasers and suppliers who increasingly share vital information and resources, their relationship has evolved from mere transactions into a working business relationship.
Strategic Sourcing: Walking the Tightrope in Developing Sourcing StrategyThomas Tanel
This presentation will focus on developing the sourcing strategy as a fundamental and logical process involving the application of tools by skilled, competent, and knowledgeable purchasers. Simply put, our focus will be on the “how to” in developing a sourcing strategy. Are you experienced?
Topics that will be addressed include spend analysis, categorizing the best opportunities for sourcing group profiles, Porter’s Five Force Model and Sourcing Grids, establishing sourcing group portfolios and supplier portfolios, using the proper RFX format for sourcing, and making strategic sourcing the focal point for supplier negotiations. Participants will view “good practice” examples of the above.
If you find yourself “walking the tightrope” with a strategic sourcing initiative or an ongoing effort, you’ll get valuable information in developing your sourcing strategy. With our five phase approach, we will discuss the following “how to”:
1. Develop sourcing strategies differentiated by expenditure category and based on market dynamics.
2. Deeply involve end-users in sourcing for knowledge and buy-in.
3. Apply a rigorous sourcing approach that examines internal needs against supply market options to find the lowest total cost.
4. Challenge specifications and usage patterns to ensure that each expenditure is providing the best value for the company.
5. Identify, analyze, select, and negotiate with strategically advantaged suppliers, not just the ones with the lowest price today.
This presentation will conclude with a presentation review that can refine your understanding of the factors, tools, and guidelines you need to make your sourcing process more effective and more profitable for your organization.
Preventing and Managing Supply Chain DisruptionsThomas Tanel
Supply chains worldwide have been battling various risks and challenges for some time. Each challenge not only threatens to disrupt operations, but also may have a negative financial impact on business performance and prevent an organization from meeting the demands from stakeholders, customers, shareholders, and regulators.
Supply Chain Council members have reported that less than half of enterprises have established metrics and procedures for assessing and managing supply risks and organizations lack sufficient market intelligence, process, and information systems to effectively predict and mitigate supply chain risks. Does this sound like your organization?
f so, supply chain disruptions can be extremely costly. A disruption in your supply chain can cost millions of dollars in lost time, energy and resources. Their effects are both direct (e.g. halting production altogether) and indirect (e.g. on stock values). Taking steps to help reduce supply chain disruption is the only way to avoid these costs.
Proactive discovery and visibility of risks is the key to the prevention and management of supply chain disruptions.
Top 10 Logistics Risks in the Spirit of David LettermanThomas Tanel
The simple fact is that in today’s longer, more global supply chains, product moves over greater distances and across more multinational borders than in the more localized supply chains of the past. The coordination and execution required for international shipments has always been a challenge. But now we find that market conditions, security considerations, transportation versus inventory costs of ownership, increasing regulatory and political pressures, and even natural events (such as storms and earthquakes) with increasing frequency and havoc are converging in such a way that it makes the task even more daunting.
Proactive discovery and visibility of logistics risks is the key to the prevention and management of supply chain disruptions. And a key ingredient in managing supply chain disruptions is risk identification; so attend this valuable presentation to find out what the Top 10 Logistics Risks are (in the spirit of David Letterman) that you will be facing in the coming years. Donald Rumsfeld, former US Secretary of Defense quipped in 2002, “Reports that say that something hasn’t happened are always interesting to me, because, as we know, there are known knowns; there are things we know we know. We also know there are known unknowns; that is to say we know there are some things we do not know. But there are also unknown unknowns-—-the ones we don’t know we don’t know.”
General Gus Pagonis, in charge of logistics during the First Gulf War in 1991 describes it best in his own words, “Logisticians deal with unknowns. They attempt to eliminate unknowns, one by one, until they are confident that they have done away with the possibility of paralyzing surprises.” Are you equipped to succeed in a supply chain world of increasing difficulty and insecurity and multiple interconnected supply chains? Do you have the correct response to a supply disruption in the supply chain and the attendant Top 10 Logistics Risks?
Why is logistics risk management in the supply chain so important now? You’ve spent years streamlining operations, reengineering processes, integrating with partners, implementing purchasing, contract management and supply chain systems, and moving production to low-cost, offshore locations. You’ve done all of this in order to get a global supply chain that really works. Finally, you can take a deserved rest, right? Unfortunately, the answer is no-—-you must learn to continuously adapt to a volatile, uncertain, complex, and ambiguous logistics environment!
As noted by Charles Darwin, “It is not the strongest of the species that survives, or the most intelligent that survives. It is the one that is the most adaptable to change.”
Risk management is about having a systematic way of dealing with thin
Tips on Negotiating better in Cross-Cultural RelationshipsThomas Tanel
Nowadays, organizations of all sizes search for suppliers on a global level. International competition, foreign suppliers, and global sourcing may become a danger, but they may also create huge opportunities to develop your business. The increasingly global business environment requires purchasers to approach the negotiation process from the global business person’s point of view.
When you understand the personal, national, or organizational culture of your negotiation counterpart, then you can seek to align with them and hence gain greater influence. In this presentation, we attempt to bring these patterns of awareness to your attention:
Cross Cultural Communications and Negotiations
Hall’s Context, Chronomics, and Proxemics
Hofstede’s Five Key Elements of Culture
Paralanguage and Tips on Negotiation Better
So what?...you say. Given that cultural differences exist, the issue becomes how do they influence negotiations. Even though language molds thinking, other cultural classifications have a pervasive effect on how the world is perceived, how the self is experienced, and how life is organized.
Learning to communicate and negotiate business across cultural boundaries is paramount as today’s workplace rapidly changes because:
The business environment expands to include various geographic locations and span numerous cultures and,
The United States becomes more multi-culturally and ethnically diverse.
This presentation is designed to give purchasing, materials, supply management, sourcing, contracting, logistics, acquisition and procurement personnel a process of value measurement to quantify the value of purchased goods or services. Learn how to use Value Analysis to target goods and services where cost can be reduced, performance improved, quality enhanced, non-essentials eliminated, downsized, or consolidated through a step-by-step process of value identification and measurement.
The genesis of value analysis and value engineering can be traced to similar, parallel developments in the late 1940’s taking place at General Electric Company and Ford Motor Company. As a concept definition: it is the organized and systematic effort and study directed at analyzing the functional requirements of the system, product, equipment, facility, service or project for the purpose of achieving the lowest overall total cost at the best value. This means consistent with the needed performance, reliability, quality, and maintainability.
Join the trend of many purchasing, sourcing, contracting, and supply management organizations who are reaping the rewards of Value Analysis (VA) and Value Engineering (VE) as a practical tool to improve performance and reduce the cost of goods and services. Their experience with cost reduction projects reveals that by merely determining what things cost and documenting cost breakdowns, one can reduce costs 5%. Improving the choice of material, conceptual design, and methods can further reduce cost by another 10%. Finally, developing a better way to perform what a project or a service was originally intended to do, one can save even more—20-30% and beyond!
Not convinced of the critical importance of value analysis/value engineering VA/VE--- then you must not be interested in product enhancement, service concept augmentation, cost reduction, and profit improvement. Those kinds of payoffs don’t come easily, however. Success depends on three things: understanding of the concept by those who will be involved, strong top management support, and enthusiastic team or project oriented direction to get and keep the program rolling.
No wonder that Purchasing magazine for years dedicated an annual issue to its “Value Analysis of the Year” Awards. Why? According to experts, VA/VE can make a difference: simple projects can take anywhere from one day to six weeks to implement with savings up to $2,000; intermediate projects can range from six weeks to six months with savings of $2,000 to $10,000; and complex projects can take six months to six years with savings ranging from $10,000 to $1 million.
Practically Applying Sourcing Grids for Risk Management Thomas Tanel
Purchasing and supply management have never been easy. The past several years have caused many executives and professionals to lose more sleep and gain more gray hair (or lose more hair) than usual; therefore, the next decade requires upgraded skill sets to survive.
Portfolio analysis is one of the most powerful techniques
used by the purchaser, despite its simplicity. It is a simple “grid” tool that charts the amount we spend on products or services and the complexity of its acquisition.
Portfolio analysis helps us define our sourcing strategy and the best sourcing techniques to use dependent upon the position on the sourcing grid. It also defines the relationships (supplier positioning) we need to have with our key suppliers and gives us an insight in how the key suppliers may see us in perception model. It allows you to organize your time and
resources for maximum benefit and it encourages strategic thinking and analysis to reduce cost, add value, and minimize risk.

Affinity Laws for Variable Speed Centrifugal PumpsVijay Sarathy
In retrofit jobs, depending on the application & plant revamps, fixed speed pumps are retrofitted with a variable frequency drive (VFD) to enable them to be operated at a different set of operating conditions. In Brownfield projects, design engineers would sometimes face situations where the manufacturer's datasheets indicate performance curves only for rated speeds & it becomes necessary to evaluate what are the other operating ranges the same pump can be used for after retrofitting.
In the following short article, I've put up some points covering
1. Advantages of Variable Frequency Drives
2. When VFD’s Are Not Advantageous
3. Selection Process - New Pumps & Retrofit Pumps
4. Example Case Study to generate Performance Curves for VSD Retrofit (Single Stage End Suction Centrifugal Pump)
Control and Monitoring of Hydro Power Plants A Reviewijtsrd
In hydro power plants there is a main interest for the implementation of digital systems for control and monitoring replacing the conventional control systems for power, speed and voltage. As a result it is indispensable to build up mathematical models accomplished to accurately describe both dynamic and stationary behavior of the hydro plants, in order to be able to execute digital control algorithms. A significant development in stability of the system has been observed. This paper presents the comparison of simulation and modeling of the hydro power plants and performs of different control structures and algorithms.

High pressure common rail injection system modeling and controlISA Interchange
In this paper modeling and common-rail pressure control of high pressure common rail injection system (HPCRIS) is presented. The proposed mathematical model of high pressure common rail injection system which contains three sub-systems: high pressure pump sub-model, common rail sub-model and injector sub-model is a relative complicated nonlinear system. The mathematical model is validated by the software Matlab and a virtual detailed simulation environment. For the considered HPCRIS, an effective model free controller which is called Extended State Observer – based intelligent Proportional Integral (ESO-based iPI) controller is designed. And this proposed method is composed mainly of the referred ESO observer, and a time delay estimation based iPI controller. Finally, to demonstrate the performances of the proposed controller, the proposed ESO-based iPI controller is compared with a conventional PID controller and ADRC.
Centrifugal compressor anti-surge control system modellingIJECEIAES
From the middle of XX century, natural gas is an important mineral, widely used in the energy sector. Transportation of natural gas is carried out via gas pipeline networks and compression stations. One of the key features which need to be implemented for any centrifugal gas compressor is a surge protection. This article describes the method and develops software application intended for simulation and study of surge protection system of a centrifugal compressor used in modern gas compression stations. Within the article research method, modelling environment’s block diagram, proposed algorithms and results are described. For surge cases control and prediction, Anti-surge control block implemented which based on practical experience and centrifugal compressor theory. To avoid complicated energy balancing differential equations the volumetric flow calculation algorithm proposed which is used in combination with Redlich-Kwong equation of state. Developed software’s adequacy test performed through modeling of onestage gas compression scheme at rated speed with comparison of parameters with reference commercial software and verification of the anti-surge control system.
Optimal power flow based congestion management using enhanced genetic algorithmsIJECEIAES
Congestion management (CM) in the deregulated power systems is germane and of central importance to the power industry. In this paper, an optimal power flow (OPF) based CM approach is proposed whose objective is to minimize the absolute MW of rescheduling. The proposed optimization problem is solved with the objectives of total generation cost minimization and the total congestion cost minimization. In the centralized market clearing model, the sellers (i.e., the competitive generators) submit their incremental and decremental bid prices in a real-time balancing market. These can then be incorporated in the OPF problem to yield the incremental/ decremental change in the generator outputs. In the bilateral market model, every transaction contract will include a compensation price that the buyer-seller pair is willing to accept for its transaction to be curtailed. The modeling of bilateral transactions are equivalent to the modifying the power injections at seller and buyer buses. The proposed CM approach is solved by using the evolutionary based Enhanced Genetic Algorithms (EGA). IEEE 30 bus system is considered to show the effectiveness of proposed CM approach.

More Electric:
Our world is becoming More Electric. Almost everything we interact with today is either already electric or becoming electric. Think about it. From the time you start your day in the morning to the time you finish your day – your home, your car, your work, your devices, your entertainment – almost everything is electric. Imagine the energy needed to power this. Electricity consumption will increase by 80% in next 25 years
More Connected: Our lives are also becoming more connected. The Internet has already transformed the way we live, work and play. Now the Connected Things is going to take this to a brand new level. 50 billion things connected in the next 5 years.
More Distributed: With such a widespread electrification and connectivity, energy models need rethinking as well. Which is why the generation of power needs to be closer to users. Distributed Energy is rapidly evolving globally. This is positive energy – renewable. In 2014 , Renewables overtook fossil fuels in investment value, with $295bn invested in renewables compared to $289bn invested in fossil fuels. And it is getting cheaper to do this.
More Efficient: When our world is more electric, more connected and more distributed, new opportunities emerge and allows us to tap into even more efficiency – in industrial processes, in the energy value chain, in buildings, in transportation, in the global supply chain and even in the comfort and peace-of-mind of our homes.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Three Steps for Reducing Total Cost of Ownership in Pumping Systems
1. by Lionel Gaudrel and Arnaud Savreux
Executive summary
Electricity usage costs have become an increasing
fraction of the total cost of ownership (TCO) for
industrial pumping systems. In fact, energy cost
represents 40% of the TCO of a typical pump. It is
possible to reduce the electrical consumption by at
least 30% through appropriate energy management
practices while reducing the maintenance cost. This
paper explains how to reduce TCO with a limited
investment.

2. Three Steps for Reducing Total Cost of Ownership in Pumping Systems
Introduction
Wherever pumping systems are present–in environments such as buildings and water /
wastewater and oil and gas facilities–energy consumption exerts a major influence on cost.
Despite the fact that electrical energy cost represents 40% of the total cost of ownership (see
Figure 1) of pumping systems, many organizations fail to introduce the proper steps to
leverage cost reduction through efficiency improvements. To solve this dilemma, the following
major barriers need to be recognized and addressed:
Lack of proper metrics – Energy efficiency has traditionally not been used in
assessing performance. In most organizations, the responsibilities of energy
procurement and efficient operations are separate and consistent / standardized
metrics are not utilized.
Knowledge gap – A lack of awareness in energy efficiency opportunities is
prevalent and, as a result, potential savings and other benefits are missed.
Fear of investment – Operations personnel often struggle to present attractive large
or even small investments to their finance organizations.

This paper demonstrates how deployment of an energy management plan, with limited
investment, can provide reductions in pumping systems TCO while maintaining sustainability
objectives. Any sound energy plan should take into account the following three steps:
1. Energy efficiency management
2. Asset management
3. Energy cost management
For the purposes of this paper, the scope of a pumping system will be defined as
encompassing all related elements starting from the point of the electrical utility connection
down to the point of end use. This paper will illustrate how energy management best
practices can result in a 20% reduction in TCO and a return of investment (ROI) within 24
months.

Step 1: Energy
efficiency
management
Energy efficiency is now a global high priority for both industrialized and emerging countries.
The Rio conference and Earth Summit of 1992 and the Kyoto Protocol of 1997 resulted in the
signing of a global treaty that sets binding targets for reduction of greenhouse gas emissions.
The International Energy Agency (IEA) and various governments and non-governmental
organizations (NGOs) agree that the reduction of CO2 emissions and the resulting energy
savings can be achieved through the deployment of energy efficient products and systems.
The challenge, however, is that the nature of production in industrial environments is in a
constant state of flux. Production cycles, for example, are influenced by variables such as
market demand, weather, and local regulations. As a result, factory and building operators
need to understand how and when energy is used in order to minimize consumption and
related costs.
The pump system energy management approach discussed in this paper will review the
nature of efficiency loss not only for individual components within the system, but also for the
system as a whole, integrated entity.
In pumping systems, most inefficiency comes from:
A mismatch between the pump deployed and the actual system requirement (i.e.,
undersized or oversized)
The improper use of throttling valves and damper technologies to control th e flow of
liquids
These two elements imply that the way pumping systems are controlled plays a major role
regarding how efficiency can be improved. Control systems themselves are composed of both
hardware and software components. On the hardware side, variable speed drives are a
primary enabler of high efficiency performance.

The example in Figure 2 on page 3 compares two installations (one with a variable speed
drive one with a fixed drive throttled system) in which static heads (height difference between
the source and the end use) are different.
At fixed speed (the throttled system example), it is necessary to add a throttle valve in
the hydraulic circuit. This adjusts the flow by increasing or decreasing the flow
resistance. This will modify the system curve. However, the speed remains the same so
the pump curve does not change. The flow rate is matched but the head is much higher
than required resulting in poor energy savings.
If a variable speed drive is deployed, the system curve does not change. The pump
curve is modified according to flow speed and affinity laws (rules of hydraulics that
express the relationship between variables involved in pump performance such as
head, volumetric flow rate, shaft speed, and power). Adjusting the speed matches the
process requirement and results in significant energy savings.
Energy savings depends on the static head: the lower is the static head, the bigger the
energy savings (and speed variation range). In order for a pumping action to occur, it is
necessary to generate enough power to overcome the static head. The friction h ead is the
amount of head required to push the liquid through the pipe and fittings. It depends on flow
rate, pipe size, pipe length, and viscosity.
Scenario 1 (Figure 2): the static head represents 50% of the system head, and the
pump is rated for the head and flow of the system. At 100% flow, the power
consumed by the pump is the same at both fixed speed and with a variable speed
drive. At 60% flow, the energy savings resulting in the variable speed drive use is
46%.
Scenario 2 (Figure 2): the static head represents 85% of the system head, and the
pump is oversized by 20%. In real world scenarios, 75% of pumps are oversized (by
10% to 30%) in order to meet anticipated lifetime peak production, to anticipate
future needs, or to rationalize spare parts inventory. Therefore, a variable speed
drive saves 20% of energy at 100% flow and saves 36% energy at 60% flow.
Changing the operating point on the pump curve also changes the efficiency of the pump
itself. The pump performs at maximum efficiency at its full capacity. This corresponds to what
is referred to as the Best Efficiency Point (BEP). In terms of installation design and operation,
the objective is to work as closely as possible to the BEP. By varying the speed, the pump
efficiency remains roughly the same but is applied to a new flow rate. At fixed speed,
reducing the flow rate quickly deteriorates the pump efficiency (because it works far from the
BEP) while adjusting the speed keeps the efficiency close to the BEP (see Figure 3).
Determining pump efficiency is only a first step in identifying system performance levels.
Monitoring efficiencies via software can detect operating points that are not suitable for the
pump. Access to such data can help to improve both system energy efficiency and reliab ility.

Summary of pump energy efficiency management best practices
The energy efficiency of a pumping system can be improved by implementing the following
simple actions:
Replace fixed drives with variable speed drives to boost the efficiency. Connected to a
pump, a variable speed drive can control speed, pressure, and flow in conjunction with
dynamic process and production requirements.
Monitor production data and energy consumption data via software dashboards.
Continuous tracking of the deviation between production output and energy consumed
allows for rapid and cost effective decision-making. Intelligent Electronic Devices
(IEDs) such as variable speed drives that are tied into the monitoring system, play a
major role in reporting data related to operation, production, and energy in real time.
Monitoring points should be close to the load because that is where most of the power
is consumed. The closer the monitoring is to the load, the more insights can be
acquired relative to cost savings.
Monitor the operating point of the pump and its efficiency on a continual basis in order
to visualize trends. Observance of the trends can then lead to sensible actions that
improve efficiency, and verify the impact of improvements to the system.
Use proper metrics to identify an increase or decrease in efficiency on particular
systems and to compare efficiency performances of different pumps in multiple sites. A
recommended key performance indicator (KPI) metric is the specific energy
3
consumption metric (in kWh/ m ).

Efficiency standards: Motors
In the realm of efficiency improvement, motors play an important role as part of the overall
pumping system. In 2008, the International Electrotechnical Commission introduced the
IEC60034-30 and IEC60034-31 standards as an efficiency classification system for motors.
Countries have published laws and regulations based on these standards and require the
usage of more efficient motors in order to reduce CO2 emissions. Table 1 aligns the various
levels of standards across different geographical regions.

Over the next several years, government regulations will require higher efficiency motors.
European Union countries that require IE2 motors today will require either IE3 motors or IE2
motors with variable speed drives in 2016. An IE3 motor will increase efficiency by 2% for
4kW / 5HP motor power when compared to an IE2 motor, and by 1% for a 90kW / 125HP
motor. Although these gains are significant, if variable speed drives are deployed, the
potential for further efficiency gain is greater.
Efficiency standards: Pumps
“As of January 1st 2015,
pumps must attain an MEI
of 0.4 or higher. That
means that 40% of
manufacturers’ current
inventory will be rendered
obsolete
As with motors, new standards and regulations have been adopted in the domain of pumps .
The European Commission (EC), for example, has adopted regulation n°547/2012 under
Directive 2009/125/EC in regard to eco-design requirements for water pumps. The EC
regulation is intended to suppress the availability of low efficiency water pumps. It is
applicable in the European Union to rotodynamic water pumps for pumping clean water.
The EC regulation defines a Minimum Efficiency Index (MEI) for affected pumps. The MEI is
a criterion based on evaluation of European pump manufacturer statistical data, on
technological aspects, on fluid dynamic laws, and on operating points included between 75
and 110% of the BEP flow rate.
According to regulation n°547/2012, as of January 1st 2013, pumps must attain an MEI of
higher than 0.1. This affects the manufacturers of pumps because 10% of their configurations
have been rendered obsolete. As of January 1st 2015, new pumps being sold to end users
must attain an MEI of 0.4 or higher. That means that 40% of manufacturers’ current inventory
will be rendered obsolete. The efficiency increase between MEI 0.4 and 0.1 is around 5%.
In order to further expand efficiency gains, the European Union has requested a new
directive which defines a broader view of the pumping system. Moving forward for efficiency
measurement purposes, a pumping system will include the pump, the motor, the load profile
and the variable speed drives. This will result in a potential savings of 30% compared to 3.6%
with the current “pump only” approach.

The IEC regulation n°547/2012 does not yet include fire fighting pumps, self priming pumps,
displacement pumps, pumps for private and public wastewater and for fluids with a high
solids content, pumps for swimming pools, pumps for fountains, and clean water pumps
larger than 150 kW. (In many of these areas preparatory studies are underway for the future
development of new efficiency standards).
Other regions in the world have defined their own minimum energy performance for pumps.
The calculation method in Brazil is similar to the EU approach. In China, the regulation
GB19762-2007 is applicable for clean water pumps. That regulation defines 3 grades where
grade 1 is used for very high efficiency pumps. Grade 3 is the minimum efficiency authorized.
The method of calculation used to define the grade is different from the method used by EU
regulation. The US Department of Energy (DOE) has begun work evaluating new energy
standards for pumps. The DOE has published a rulemaking framework and has shared
documents regarding commercial and industrial pumps with manufacturers, consumer
groups, federal agencies, and states in order to gather feedback.
Step 2: Asset
management
Physical assets such as pumps need to be maintained on an ongoing basis. Maintenance
costs represent 25% of TCO (see Figure 1) and therefore maintenance practices warrant
examination in terms of contribution to energy-influenced savings. Maintenance costs are
unavoidable due to the wear of components during system operation, and because the cost
of downtime attributed to loss of production would threaten the solvency of the business. In
pumping installations, many moving parts mean that proper maintenance of motors, drives,
pumps, and associated pipes is crucial. Numerous steps can be taken to assure that
maintenance costs are kept at a minimum while integrity of the systems is kept stable.

All pumps should be operated within the parameters of a given pump’s specifications (often
stated in the pump supplier’s instruction manual / data sheet). As discussed, pump efficiency
varies according to operational parameters. The pump is designed for optimal operation at

the best efficiency point (BEP) but 75% of the pumping systems are oversized by around
30%. Figure 4 (previous page) illustrates how pumps begin to waste significant efficiency
when appropriate maintenance practices are neglected. For example, discharge recirculation
can occur if the pump operates at 65% of the BEP flow rate, causing damage to the impeller,
and a damaged impeller will be less efficient.
Variable speed drives can help to keep the operating point close to the BEP and also protect
the pump against destructive forces generated by inefficiencies. Extreme situations such as
dry running, low flow operation, or cavitation (due to low net positive suction head) which can
cause instantaneous damage are avoided. Monitoring the operating point of the pump and its
efficiency provides diagnostics that can help predict when potential system problems will
occur.
Figure 5 illustrates how operating away from the BEP not only decreases the efficiency but
speeds up the wear and tear on the pump thereby reducing reliability. For example,
operations run at 60% of BEP result in:
50% lifetime reduction of seals
20% lifetime reduction of bearings
25% lifetime reduction of casing and impeller

Wear is unavoidable due to mechanical parts that are moving and to the action of the fluid
being pumped. Erosion is generated by the speed of fluid, and it could be increased by
slurries (sand or bigger particles). Corrosion is due to chemical or electrochemical reaction
that attacks the pump materials. Even treated drinking water causes corrosion in cast iron
casings as a result of the catalytic effect of bacteria. Erosion and corrosion mostly impact the
pipes, the impeller, and the case (which are key operating components).

Efficiency drops by 10 to 15% for an unmaintained pump (see Figure 6). Moreover, the major
loss in efficiency occurs in the first few years of the pump’s life. Regular maintenance avoids
losses in efficiency and capacity which can occur before the pump fails.

Some of the factors that debilitate a pump are visible. Others are not. For example, a worn
seal is apparent. However, hydraulic wear is not. A problem that is not visible occurs before it
is identified. This creates a situation of urgent corrective maintenance, and the defects may
have affected other parts of the pump.
Maintenance practices
A number of approaches are available that can help to address the issue of maintenance in a
cost effective manner. Preventive maintenance implies the systematic inspection and
detection of potential failures before they occur. Condition-based maintenance is a type of
preventive maintenance, which estimates and projects equipment condition over time,
utilizing probability formulas to assess downtime risks. Corrective maintenance is a response
to an unanticipated problem or emergency.
Figure 7 illustrates the cost curves of these three types of maintenance. Condition -based
maintenance is the most cost effective of the three approaches.
Condition-based-maintenance monitors system data on an ongoing basis and provides an
accurate assessment of the health, or status of components, devices, and / or the complete
system.
As it relates to pumps, variables such as suction pressure, discharge pressure, pump speed,
power, flow, and temperatures are monitored to detect a loss of efficiency. Identificat ion of
the potential problems is possible by combining the efficiency trends and process variables.

Pipes
As part of the overall pumping system, pipes are also subject to issues such as overpressure,
leakage, or pipe burst. An overpressure situation can be caused by poor pump control. A
situation called “water hammer” can also occur. Water hammer is caused by a pressure or
shock wave that travels through the pipes, generated by a sudden stop in the velocity of the
water. This sudden acceleration and deceleration on the motor can be avoided with the help
of a variable speed drive (sudden variation in flows is avoided). Leakage can also be reduced
by automatic adjustments to pressure when appropriate.
Motors
Protection against mains voltage and frequency fluctuations can help maintain the integrity
and extend the lifetime of motors. In cases where motors are equipped with variable speed
drives, those electrical disturbances are not transmitted to the motor.
Protection against high temperature conditions can also extend the life of the motor assets.
Devices such as thermal relays, PTC or PT100 thermal sensors can help and are
manageable through the variable speed drive.
In cases where long motor cables are used in conjunction with motors and variable speed
drive, it is recommended that filters be installed in order to avoid the dv / dt and motor voltage
surge effects (see the Schneider Electric white paper “An Improved Approach for Connecting
VSD and Electric Motors” for more details on this subject). Note: For submersible bore hole
pumps, it is recommended to verify the peak to peak voltage and the dv / dt at the motor
terminals with the motor-pump supplier.
Step 3:
Energy cost
management
Building owners, water / wastewater and oil and gas facilities operators are presented with
utility bills that have multiple components. These can include power demand charges, energy
demand charges, time-of-use charges, ratchet clauses, cost-of-fuel adjustments, power factor
penalties, customer service charges and national, regional, and local taxes. A
misinterpretation of utility rate structures can lead to poor management of electrical
consumption and to higher costs.
Most energy bills cover similar basic elements (see Figure 9). Familiarity with the terms can
help to understand where the opportunities for cost reductions exist.
Figure 9
Fundamental elements of
a typical industrial
electrical bill
Below are some definitions for common terms used:
Customer charge – This is a fixed charge that depends upon the size of the connection that
links the industrial installation in question to the electrical utility network. The customer
charge is calculated according to an anticipated power consumption range, and the price of
Schneider Electric White Paper
Revision 0
Page 11
12. Three Steps for Reducing Total Cost of Ownership in Pumping Systems
the actual power that is consumed. Both of these elements are influenced by the type of
contract that has been signed between the corporation and the utility.
Harmonics
Actual energy charge – This charge corresponds to the consumed active energy, which is
the cumulative energy consumed over a given period of time. The kilowatt hours (kWh) rate
depends upon the time period the energy was consumed, and whether that consumption
occurred during “peak” and / or “off peak” hours.
Industrial sites can also be
penalized by the utility if the
electronics equipment within
their walls generate an
inordinate amount of harmonics
(electronic disturbances) back
up the grid.
Demand charge – This charge represents the highest average power consumed within any
15 minute time period over the span of a month’s time is tracked by the utility. This number is
then multiplied by the demand charge rate in order to produce the demand charge that
appears on the electrical bill. That means consumers are charged for a peak demand even if
it only happened once during the month.
A detailed explanation of how to
reduce harmonic effects is
provided in the Schneider
Electric white paper entitled
“Operational Cost Avoidance
through Harmonic Mitigation in
Industrial Environments”.
Power factor penalty - The power factor is the ratio between the active power (that
generates work) and the apparent power (that could potentially be used to generate work).
That means that a certain portion of the power that is delivered by the electrical utility to the
industrial site is not billed (because it did not generate work). If the power factor is less than
the given value mentioned in the contract (say around 0.9), the consumer is invoiced for the
power factor (reactive power). A lot of equipment or devices have power factor lower than 1:
motors, induction furnaces, transformers, variable speed drives, c omputers, fluorescent
lighting.
Best practices for energy cost reduction through bill management
The electrical energy bill for the site can be reduced by implementing the following series of
simple actions:
Locate and review the utility contract itself to better understand the charges associated
with the bill and how they can be controlled. Up to 10% savings without any capital
investment could be achieved with the support of a company specialist in energy
management.
Adjust the timing of energy usage from the peak rate period to the off peak period as
much as is possible (e.g. by controlling differently reservoir and pumping operations).
Reduce the monthly peak demand number in order to reduce the demand charge. In
most cases, 75% of the applications are oversized. Variable speed drives, which can
reduce power demand by 20%, are a technology that helps organizations to size
according to process requirements.
Power factor penalties that are due to motor and that mitigate harmonics at 48% of
THDi for 80% load, can be canceled out by deploying variable speed drives to pumps.
Reduce the amount of energy that is consumed that is not linked with revenue
generation. An active control of the leakage will significantly reduce the operational
cost.
