Optimizing Pipeline Energy Consumption
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.
Cost savings and environmental stewardship through
effective energy management

4. Introduction
White paper on Pipeline Management | 02
Optimizing Pipeline Energy Consumption
Electric energy transmission and distribution networks are becoming ‘smarter’
through the use of highly available data about the status of the grid – data that
helps support more efficient operations and business processes. More and more,
the concept of a ‘smart grid’ appeals to pipeline operators as well: they face
significant internal and external drivers to use pump and compressor energy more
efficiently and reduce their ever-increasing energy consumption costs.
Real-time operations data, already available in a pipeline SCADA system, can help
examine current energy consumption and test alternative operating scenarios
for improved cost efficiency. This information is highly revealing and can help
overcome the challenges of energy management for today’s pipeline operator –
and support benefits across the enterprise.

Optimizing Pipeline Energy Consumption
With hydrocarbon pipeline networks becoming more complex and operations
more complicated, operators must address long-standing operating challenges:
• Safety of people and property
• Delivery commitments
• Regulatory requirements
• Reducing emissions for ‘greener’ operation and carbon credits
• Social responsibility and good stewardship
Operators typically have placed priorities on meeting commitments, complying
with regulations, and satisfying safety and security concerns; their control room
personnel have focused on the real-time dynamics of batch scheduling, pipeline
hydraulics, contracts, and current and forecasted operating conditions. In many
cases, energy consumption has not been a leading issue for the company.
However, the cost of the energy required to operate the pipelines – already the
leading expense for most operators – is rising continuously and now ranges from
40 to 65 percent, or more, of total operational costs. Added to the rising energy
consumption is an increase in carbon emissions of each pipeline.
Energy management has become more significant for the pipeline operator, not
only as a standalone cost issue but also as a process that can help accomplish
other operational and business goals.
Part 1: Optimizing Pipeline Energy
Consumption
It’s all about cost reduction
Power optimization doesn’t necessarily target
reduced energy consumption; instead, it
targets the cost of the energy consumed
during pumping operations. Simply, it
determines the energy (KW) and cost ($) of
a pipeline’s operation at a specific moment
in time and then uses this information to
determine the optimum pipeline pump
configuration and drag reducing agent (DRA)
injection rates that would minimize cost.
Energy consumption costs commanding
attention
While energy management is challenging, it grows
more vital for pipeline business

7. Optimizing Pipeline Energy Consumption
White paper on Pipeline Management | 05
What pipelines would benefit from energy
management?
Each pipeline operates in a different manner and will realize cost benefits at
varying levels. Some of the operating factors that are considered in power
optimization include:
• Duty cycle of the pipeline
• Length of pipeline; does it transverse different states or multiple energy
rate contracts?
• Number and types of products in the pipeline
• Number of stations on the pipeline and alternative operating modes
• Use of drag reducing agent (DRA)
• Current maintenance status of the pumping units
• Overall energy management program of the pipeline
Pipelines that run at 100 percent capacity or with less complex contracts have
fewer options for energy consumption improvement, since at least one pipeline
segment generally has pumps running at their highest capacity and/or DRA
is injected at its highest rate. Yet, even this pipeline can benefit from power
optimization, as other sections of the pipeline likely still have options for pump
status selection and/or DRA injection rate.
Benefits are both tangible
and creditable
By committing to a power optimization
program that allows documentation of
energy usage and savings, a pipeline
operator reduces electricity consumption
and associated costs and emissions. This
approach not only reduces bottom-line
expenses, it also generates carbon credits
that can be sold or traded on the open market
per industry and/or government regulations
or applied to help meet overall carbon
footprint limits – and reap the marketing
benefits of being a ‘green’ organization and an
environmental steward.

The challenges of effective
energy management
Energy management requires a comprehensive commitment on the part of
the company to:
• Dedicated resources—the operator must be willing to invest in the
appropriate personnel, skills, and technology tools.
• Planning and scheduling—the operator must look at energy
management as a comprehensive component to management
and not let obligations to satisfy shippers and customers
overshadow the effort required to plan and schedule the energy
required.
• Real-time monitoring and optimization—to effectively manage
energy use, the operators must have timely pipeline information,
a responsive calculation solution, and the means of implementing
the recommended functions.

White paper on Pipeline Management | 08
It is vital that the operator know its operating costs at any particular time. With
this knowledge, the operator can quickly and confidently make operating
decisions that support both energy efficiency and operational integrity.
In addition to current conditions, other cost and operating scenarios can be
considered:
Cost of proposed, or ‘what if’ configurations for the real-time state identifies
the cost of a modified configuration, at the current time or at some future time.
This costing category gives the operator a chance to evaluate a different pump
configuration before actually implementing it, to determine if it would reduce
energy cost –
• Investigate pumping schedules using normal pump rates when the
utility charges low time-of-day rates, or
• Choose to use more power to drive faster pumps for priority orders,
while still spending less on the energy required.

White paper on Pipeline Management | 09
Cost of an optimized configuration identifies the cost of an optimized
configuration with the current conditions and time –
• Learn to sequence jobs in order of individual demands. With fewer
pump starts and stops and a more consistent usage pattern, the
operator minimizes usage spikes and their associated penalties.
• Consider pump performance to identify the most efficient
configuration that can accommodate extra load at least cost; see
Figure 1.
• Factor personnel costs to determine if an ‘overtime avoidance’
strategy is counter-intuitive to one using less power but more
personnel hours.

White paper on Pipeline Management | 10
Top three ways to optimize
pipeline energy costs
• Know your present operating costs and
how costs change with demand charges
• Identify optimal pumps, and minimize
pump throttling
• Identify optimal DRA injection locations
and rates. Most companies follow
generic guidelines and don’t even
consider pipeline status when making
DRA injection decisions. Taking into
account the effectiveness of the DRA,
the cost of the DRA, the increased
throughput, and the resulting power
savings helps determine the best DRA
flow rate based on current conditions.
Demand charges can significantly increase energy rates for prolonged periods
of time, and the operator should avoid them as a matter of practice. Knowing
when a costly energy rate transition is approaching would give the operator the
ability to minimize the impact of the higher energy and/or demand level:
• Early Warning for the real-time state – knowing the cost of the
current configuration at the next energy rate boundary; it tells the
operator what the cost will be if no configuration change is made.
• Early Warning optimized – knowing the cost of an optimized
configuration at the next energy rate boundary
• Early Warning optimized at current time – knowing the cost of a
future optimized configuration at the current time
Solution options
So what can the pipeline operator do to make energy use more efficient?
Efficient equipment.
Certainly, pumps, compressors, and other vital transportation pipeline assets
are becoming more efficient and will continue to evolve in their capabilities.
High efficiency equipment can cut costs on a site-by-site basis, but it does not
provide a solution for system-wide optimization. By having to continuous invest
in new equipment, the operator is minimizing returns.
Information management technology.
In commodity delivery networks everywhere, including water systems
and electric and gas power distribution systems, operations are not only
becoming more complex but they also are losing experienced personnel to
retirement. Veteran employees take with them innate knowledge of manual
network management. Enter their replacements: a generation groomed in the
technology era and ready to embrace information management tools that give
them similar decision-making knowledge.
Cost control scenarios also look ahead

To serve as a practical system-wide solution – and, therefore, be most effective in
delivering energy savings – a pipeline power optimization solution must integrate
the tools and data sources that will:
• Summarize the cost of the current configuration
• Offer an optimized operational scenario accommodating current
conditions and requirements
• Perform costing runs to alert of approaching rate transitions
Below are the components that, when integrated, deliver this comprehensive
capability –
Real-time information. This key element of the solution interfaces with the
pipeline’s supervisory control and data acquisition (SCADA) system, acquiring
from the SCADA real-time data such as pressures, temperatures, flows, pump
and valve status, and – if available – kilowatts. This approach allows system-wide
energy optimization, compared to site-specific optimization that high-efficiency
pumps implement.
Simulation software. The solution then feeds the real-time data to a steady-
state model, or pipeline simulation, that merges state-of-pipeline data with
critical business information. This high-fidelity simulation model calculates costs,
generates the optimized solutions, and maintains ‘tuning’ information to keep
the simulation an accurate model of the real world. The realistic pipeline-state
calculations created signal the cost-savings value of altering specific conditions.
A system-wide solution returns efficiency savings and
supports enterprise safety, security, and environmental
responsibility

The simulation uses this information to generate the current costs; it also
compares costs of alternate pipeline configurations to determine the optimal
option for the current pipeline state. An additional interface factors future pricing
to warn of approaching costly rate transitions. This module even supports spot-
pricing from the utility through online downloads; see Figure 5.
Demand recorder element. This element manages the database that stores key
data such as kilowatt information for each demand interval on a per-pump or
per-compressor basis. It mimics the power utility’s field demand recorders that
generate the interval data driving the utility’s brackets and demand charges.
Sequencer module. This module coordinates simulation information: pipeline
current state calculations, potential optimization, early warning, and operator or
engineer ‘what-if’ scenarios.

technology, enabling the user experience to be fully within the browser while
providing engineering with a full-featured desktop application.

Schneider Electric’s Energy Management Application Suite (EMAS) – Power
Optimization solution was developed in close cooperation with major industry
operators to ensure it addresses all the operational needs and enterprise goals
discussed above. It seamlessly integrates real-time operational parameters
from the system SCADA with simulation software, a costing element, demand
recorder, sequencer module, and web-based GUI to accurately identify current
and optimized configuration scenarios. This approach has shown to help
energy managers fine-tune power consumption and reduce operating costs
by 1 percent to 5 percent or more, depending on pipeline characteristics and
complexity of the operator’s contracts.

Power optimization in the
control room
A power optimization application using
real-time information can provide
recommendations on:
• Present situation – a cost summary of
the current configuration at the current
time
• Early warning – alerts that summarize
the current configuration at the next
rate boundary and help avoid costly rate
transitions
• ‘What if’ scenarios – cost summary of
a modified configuration at the current
time or at some future time
With this meaningful, real-time information,
controllers use their expertise to implement
the safest, most cost-effective processes.
Energy managers will want to work with
controllers to help them migrate from routine
operational decisions to those that also can
make significant energy-saving impacts.

20. Conclusion
Optimizing Pipeline Energy Consumption
White paper on Pipeline Management | 18
Power optimization solutions in a
nutshell:
• A system-wide power optimization solution gives the pipeline operator
valuable insights into energy spending. The operator schedules jobs based on
predictable rate schedules, sequences jobs in order of demand while avoiding
rate spikes, and favors more economical assets when accommodating extra
load.
• While improving business efficiency, it can reduce system-wide power
consumption by as much as 20 percent and save significant operating costs.
The operator can use the historical calculated energy costs stored in the
application’s demand recorder to calculate accurate energy brackets and
demand charges. With this information, the operator then forecasts future
energy consumption based on varying operational modes and can more
effectively negotiate energy rate contracts with its provider.
• Reduced power consumption can generate carbon credits for the operator
as defined by the government. As trading or selling of carbon credits grows
throughout North America, operators using a power optimization application will
be in a good position to document energy saved and the carbon credits earned
that can be sold, traded, or applied to reduce the operator’s carbon footprint.
• The real-time information continuously available through an energy management
application identifies significant operating constraints such as pump capacities,
maximum operating pressures, slack line conditions, and DRA effects. This level
of real-time information helps the operator stay on top of operational safety and
the security of network assets.
