Time to step up performance-based energy efficiency measurement and verificat...Leonardo ENERGY
How can you know for sure the energy you’ve saved through your building renovation? The answer is that you can’t! But, by measuring energy consumption and taking account of other factors, such as the weather and building occupancy, you can make a much better estimate than by simply relying on installers’ claims of effectiveness. This is well understood in industry, where contracts for energy efficiency projects are routinely set up to reward energy service companies for the savings made, based on measurement and verification protocols such as IPMVP. This shifts much of the technical risk of underperformance onto the energy service contractor, aligning incentives and driving better performance. Policy makers in the US have begun to apply these principles to utility-delivered energy efficiency programmes in the buildings sector as part of efforts to drive up performance and provide better value for money for bill payers. The EU now has the opportunity to follow suit.
V2X is an umbrella term to explain the use of Electric Vehicle (EV) batteries to provide energy services and derive additional value from the battery asset during times of non-use. V2X services aim to generate revenue from the battery asset through dynamic or bi-directional charge control to provide benefits to the electric grid or to reduce/flatten/shift peak energy consumption of buildings and can be classified in the following operating modes:
· Vehicle-to-Grid (V2G): Using an EV battery to interact with/provide value to the electric grid
· Vehicle-to Building (V2B): Operating EV batteries to optimize building energy consumption
· Vehicle-to-Home (V2H): Optimizing home energy consumption or as emergency back-up power
· Vehicle-to-Load (V2L): Any other instance of an EV battery providing energy to a load

Power system flexibility relates to the ability of the power system to manage changes.
Solutions providing advances in flexibility are of utmost importance for the future power system. Development and deployment of innovative technologies, communication and monitoring possibilities, as well as increased interaction and information exchange, are enablers to provide holistic flexibility solutions. Furthermore, development of new methods for market design and analysis, as well as methods and procedures related to system planning and operation, will be required to utilise available flexibility to provide most value to society.
However, flexibility is not a unified term and is lacking a commonly accepted definition.
The flexibility term is used as an umbrella covering various needs and aspects in the power system. This situation makes it highly complex to discuss flexibility in the power system and craves for differentiation to enhance clarity. In this work, the solution has been to differentiate
the flexibility term on needs, and to categorise flexibility needs in four categories.
Here, flexibility needs are considered from over-all system perspectives (stability, frequency and energy supply) and from more local perspectives (transfer capacities, voltage and power quality). With flexibility support considered for both operation and planning of the power system, it is required in a timescale from fractions of a second (e.g. stability and frequency support) to minutes and hours (e.g. thermal loadings and generation dispatch) to months and years (e.g. planning for seasonal adequacy and planning of new investments).
This document discusses valuing distributed energy resources (DER), including energy efficiency, on electric distribution grids. It outlines that DERs like solar PV, energy storage, and efficiency can provide both benefits and challenges to distribution system operations depending on their location and timing of use. The document recommends valuing DERs based on their locational and temporal impacts using hosting capacity analysis, scenario planning, and other tools to develop optimized DER portfolios. It also suggests using pricing, incentive programs, and procurements aligned with local grid conditions to efficiently source DERs. Accurately valuing DERs' grid support can improve planning, programs, and drive better investment decisions.

Using human-centred design to improve energy efficiency programsLeonardo ENERGY
Human-centred design is being used to make the NSW energy savings scheme more effective. We started with research that identified six key insights for improved scheme operation. It found that the scheme is complex and its fragmented tools and systems create unnecessary barriers to entry. We then used workshops to develop six corresponding opportunities for improved service delivery. To scale up we need streamlined manual processes, more collaboration and improved digital systems. This is especially relevant given recent announcements that the scheme is being extended to 2050.
This talk will present the research, and will place it in the context of changes announced as part of the NSW Energy Strategy. It will explore small, medium and long term changes to scheme delivery identified through the HCD process and our proposed next steps.
The NSW Energy Savings Scheme started in 2009. It has so far delivered projects that will save 27,000 gigawatt hours of energy and $5.6 billion in bill savings over their lifetimes.
Electric Vehicles in San Antonio by Harley Hubbard Forth
The City of San Antonio has adopted a Climate Action and Adaptation Plan with goals of carbon neutrality by 2050 including a 41% reduction in emissions by 2030. The plan outlines strategies for the city to convert its vehicle fleet to more efficient electric vehicles by 2025 and encourage residents to transition to electric vehicles. The city developed a Vehicle Environmental Acquisition Policy in 2010, which it is updating to better align with climate goals and allow departments to purchase gas vehicles only when electric models cannot meet job needs. The city is conducting public outreach on electric vehicles and researching fleet charging needs and citywide electric vehicle infrastructure requirements to support adoption.

Hybrid resources: Challenges, Implications, Opportunities, and InnovationAndrew Gelston
Many experts were initially perplexed by the rapidly growing popularity of hybrid resources, which combine multiple technologies into a single entity. Hybrid resources intentionally take on more operational responsibility by optimizing and scheduling their combined functions. They provide advantages over individual resources, including lower costs from shared infrastructure, increased flexibility to provide a variety of services, and the ability to adapt over time by upgrading components. Hybrid resources reflect logical responses to increasing complexity and risk in the electric power system.
This document discusses replacing retiring coal plants with either energy storage or combustion turbines (CTs) for peaking capacity. CTs have historically been the preferred option but are inefficient and emit pollutants. The document argues that advanced energy storage is becoming cost competitive with CTs and is more flexible, providing capacity and grid balancing services at both regional and local levels. By 2017-2018, the capital costs of 4-hour energy storage are projected to be on par with or cheaper than CTs, making storage the better option for meeting peaking capacity needs.
Electrifying Medium and Heavy Duty Vehicles by Sarah Ryan Forth
This document summarizes the benefits of electrifying medium- and heavy-duty vehicles. It notes that transportation contributes significantly to global warming and air quality issues. Electrifying vehicles can help drive reductions in greenhouse gas emissions and other pollutants compared to diesel or CNG vehicles. While the upfront costs of electric vehicles are currently higher, the economics are improving and incentives are helping speed adoption. Manufacturers are increasingly investing in electric technology and fleets are beginning to procure electric trucks and buses, especially with supportive policies from states and local governments.

The document summarizes the results of phase 1 and provides an update on phase 2 of a battery testing project. It found that Sony and Pylontech battery packs demonstrated excellent capacity retention based on cycles completed. Samsung, Tesla, BYD and Pylontech batteries showed high reliability while Samsung and BYD had high round-trip efficiency between 85-95%. The report also discussed battery market trends including price reductions stalling but expected to decrease in the medium term due to new production capacity.
The document summarizes discussions from the Arctic Energy Summit regarding enabling sustainable energy development in the Arctic. It outlines three key challenges - developing extractive energy like coal, renewable energy like tidal generation, and alternative fuels for rural communities. It also identifies eight sustainability factors that must be addressed for successful Arctic energy projects. The Arctic Energy Action Team was formed to develop solutions and a technology roadmap to meet these challenges in a sustainable manner that benefits people in the Arctic.
The document discusses several issues related to providing sufficient electricity for Honolulu's planned rail transit system, including:
1) Providing power for the rail is a major unresolved issue and cost risk, as it will require 30-50 megawatts of electricity, around a third to half of an Oahu power plant's output.
2) Hawaiian Electric Co. claims it expects to have enough generating capacity but experts warn there may not be enough power, especially during peak times.
3) If there is insufficient power, rolling blackouts could occur and the rail may get priority over other customers.
4) The document discusses smart grid technologies that could help match electricity supply and demand but implementing such solutions has challenges.
Presentation the future of bioenergy in urban energy systemsLeonardo ENERGY
The future urban energy systems can move to directions in which bioenergy will play a key role, for example as fuel for space heating, for (back-up) electricity generation, and for mobility (biofuels). A competitive deployment of bioenergy requires sufficient availability of biomass and acceptable costs. As result of the uncertainty in the price developments of bioenergy, the view on the future is uncertain as well. Also in the recent study "Urban electrification - impact of electrification of urban infrastructure on costs and carbon footprint" results were strongly dependent on assumptions on the availability and costs for bioenergy.
In this interactive workshop, we sketched the landscape of bioenergy in relation to the urban energy system and develop a joint view on bioenergy availability and cost. The workshop covered the following aspects:
* Which types of bioenergy carriers are most suitable in the urban energy system?
* What could be the availability of those bioenergy carriers?
* What would be typical costs per type of resource and what are the drivers and uncertainties?
* What is the role of policy in the cost development of bioenergy and how can the cost gap be bridged?

EEI Strategic Issues Forum - Integration of DER: California and New YorkScottMadden, Inc.
Cristin Lyons, partner and grid transformation practice leader at ScottMadden, recently presented, "Integration of DER: California and New York," at the EEI Strategic Issues Form.
California and New York are leading the country in integrating Distributed Energy Resources (DER); however, their approaches are different. It’s worth understanding some of the nuances of their respective proceedings and to clarify what they are (and are not) trying to accomplish. Each will provide unique lessons to both utilities and regulators that are attempting to integrate ever-increasing amounts of DER.
For more information, please visit www.scottmadden.com.
The document summarizes a report from the National Association of Regulatory Utility Commissioners (NARUC) on compensating distributed energy resources (DERs). It discusses the increased deployment of DERs, issues they create for utilities around compensation and system planning, and NARUC's response through a manual identifying options for jurisdictions. The manual examines methodologies like net energy metering, demand charges, and valuation approaches to help regulators address DER compensation questions.

Energy Storage Opportunities and Challenges ECOFYS Andrew Gelston
Energy storage provides multiple benefits to power systems but faces valuation challenges due to its ability to act as both generation and load. A wide range of energy storage technologies exist at various stages of development, from mature pumped hydro to promising new battery chemistries. As variable renewable energy increases, so does the need for energy storage to provide balancing services. However, energy storage development has lagged renewable growth. Accurately valuing energy storage benefits and implementing supportive policies can help address this gap.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.

Climate Change All over the World .pptxsairaanwer024
Climate change refers to significant and lasting changes in the average weather patterns over periods ranging from decades to millions of years. It encompasses both global warming driven by human emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. While climate change is a natural phenomenon, human activities, particularly since the Industrial Revolution, have accelerated its pace and intensity
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.

Traditional Distribution System Planning
What are the Issues and why is California undertaking
Specific Activities?
Distribution Resource Planning (DRP)
Smart Inverter Working Group (SIWG)
Recommendations from WIEB/SPSC Report
April 8, 2015 www.eqlenergy.com / 10
11. Background: Typical Distribution Planning
Each distribution feeder is assessed separately
Maximum load is determined for the next 3 to 5 to 10
years, based on load profiles and expected customer
growth
Additional capacity, maybe 50%, is added to ensure the
feeder can handle reconfiguration scenarios
Feeder equipment upgrades or additions are determined
These distribution costs are either just the “cost of doing
business” and/or are assessed by regulators for
reasonableness
April 8, 2015 www.eqlenergy.com / 11
12. California’s Situation with DER & Distribution
Planning and Operations
§ As part of achieving 33% renewables by 2020, California Governor Jerry
Brown called for 12,000 MW of DER, limit imports.
§ Now the goal has been updated to 50% renewables by 2030
§ DER systems are defined as distribution-connected generation, energy
storage, and (sometimes) controllable load
§ High penetrations of DER systems have the potential to provide
significant environmental and financial benefits to California
§ European experiences, including a 2003 blackout in Italy, have shown that
DER systems must support the grid for both reliability and economic
reasons
§ In particular, DER systems need to be able to “ride-through” both
frequency and voltage short-term anomalies
§ Europeans had to retrofit large numbers of DER systems to add
these critical capabilities – a very expensive action
April 8, 2015 www.eqlenergy.com / 12
13. Why Should Others Care about What is
Happening in California?
§ Renewable energy portfolios (RPS) are incentivizing
additional renewable energy, often at the distribution level
§ DER systems in low penetrations are just negative load
§ However, DER systems at higher penetrations can impact
distribution operations both negatively and positively
§ “Smart” DER technologies and grid modernization equipment
are changing the nature of distribution planning and
operations
“In the near future, utilities may no longer just supply
electricity to customers, but may have to plan for,
coordinate, and manage the flow of energy to, from, and
between customers.”
April 8, 2015 www.eqlenergy.com / 13
14. California’s Distribution Resource Planning
(DRP)
§ Purpose is for distribution planning to include DER energy capacity,
“smart” capabilities, energy efficiency, and market incentives during
long-term distribution planning
§ These factors would then be balanced against the avoided costs of
“”traditional” distribution planning
§ Process is to define a list of mutually exclusive and collectively
exhaustive (MECE) categories of values

15. Distribution Resources Planning Purposes
(1)
§ Identify optimal locations for Distributed Energy Resources
§ Evaluate locational benefits of DERs based on:
§ Reductions versus increases in local generation capacity needs
§ Avoided costs versus increased investment for distribution infrastructure,
safety benefits, reliability benefits
§ Any other savings or costs that DERs may provide to the grid or to
ratepayers
§ Integrated Capacity Analysis
§ Propose or identify standard tariffs, contracts, or other
mechanisms for deployment of cost-effective DERs that satisfy
distribution planning objectives
April 8, 2015 www.eqlenergy.com / 15
16. Distribution Resources Planning Purpose
(2)
§ Propose cost-effective methods for coordinating existing
commission-approved programs, incentives, and tariffs to
maximize the locational benefits and minimize the incremental
costs of DERs
§ Identify additional utility spending necessary to integrate
cost-effective DERs into distribution planning
§ Identify possible barriers to the deployment of DERs,
including:
– Safety standards related to technology
– Reliability requirements for the operation of the distribution circuit
April 8, 2015 www.eqlenergy.com / 16
17. Smart Inverter Working Group (SIWG)
§ California (CEC and CPUC) did not want to repeat the European
scenario and initiated the Smart Inverter Working Group (SIWG)
§ The CPUC and the CEC staff convened the SIWG in January 2013 to:
§ Develop the default DER functionality requirements and establish an
implementation plan for California
§ Update California’s Rule 21 on DER interconnection requirements
§ The SIWG currently has over 250 participants from all major
stakeholder groups, including utilities, DER manufacturers, integrators,
customer groups, investors, and interested parties
§ After the first month of weekly calls, all stakeholders recognized the
potential benefits of “smart inverters” and eagerly joined in the technical
discussions
§ California’s 3 IOUs have taken the lead in defining their requirements, while
the DER manufacturers have determined what their products and
technologies can achieve
§ Typical discussions are: “Should the timing be .2 or .3 seconds?”April 8, 2015 www.eqlenergy.com / 17
18. SIWG Results To Date
The SIWG developed a phased approach of
recommendations to the CPUC:
§ Phase 1: Seven (7) critical autonomous functions – approved
by CPUC in December 2014
§ Phase 2: Communications capabilities for monitoring, updating
settings, and control –submitted to the CPUC in late February,
2015
§ Phase 3: Additional DER functions – currently being discussed –
open to all who want to address these technical DER
capabilities
SIWG members now participating in a survey on the
importance of about 40 DER functions
April 8, 2015 www.eqlenergy.com / 18
19. Phase 1: Seven Autonomous DER Functions
– Focus on this slide
SIWG Recommendations for Phase 1 Functions (now mandatory
by mid 2016):
§ Support anti-islanding to trip off under extended anomalous conditions,
coordinated with the following functions
§ Provide ride-through of low/high voltage excursions beyond normal
limits
§ Provide ride-through of low/high frequency excursions beyond
normal limits
§ Provide volt/var control through dynamic reactive power injection
through autonomous responses to local voltage measurements
§ Define default and emergency ramp rates as well as high and low limits
§ Provide reactive power by a fixed power factor
§ Reconnect by “soft-start” methods (e.g. ramping and/or random time
within a window)
April 8, 2015 www.eqlenergy.com / 19
25. Scope of SIWG Phase 2
Communications between utilities and 3rd parties (red lightning bolts):
– (1) Utilities and individual DER Systems
– (2) Utilities and Facility DER Energy Management Systems
– (3) Utilities and Aggregators
www.eqlenergy.com / 25
26. Current Status of SIWG Phase 2
Decisions were made on initial recommendations for these and
other communication issues
Mandatory recommendations ruling through the CPUC:
– Recommended to be included in the CPUC Rule 21
Beneficial recommendations documents
– Recommended to be included in each utility’s “[Utility] Generation
Interconnection Handbook” on requirements and options
– Recommended to be included in a single “California IEEE 2030.5
Implementation Guide”
– Recommended to be decided by mutual utility-DER owner/operator
agreements on a utility basis or an installation basis
– Recommended to be left up to vendor or market decisions
April 8, 2015 www.eqlenergy.com / 26
27. SIWG Phase 3 DER Functions
Discussions on relative importance of 40 DER
functions, which need further technical resolutions, and
which should be included in Rule 21.
Some of Phase 3 functions include:
§ Provide status and measurements
§ Set actual real power output
§ Limit maximum real power output
§ Frequency-watt
§ Voltage-watt
§ Power-power factor
§ Schedule actual or maximum real power output
§ Frequency smoothing
§ Automatic Generation Control (AGC)
April 8, 2015 www.eqlenergy.com / 27
28. SIWG Efforts Spawned Updates to
Standards
This California SIWG process and other initiatives have triggered
related efforts to update standards:
§ UL 1741, required for safety of DER installations, is developing a supplement
to provide testing and certification for these functions, and is almost ready for
ballot
§ IEEE 1547, which is used by most jurisdictions as the standard for DER
interconnection requirements, was amended as IEEE1547a to permit these
functions
§ IEEE 1547 is now being completely revised to cover these and a number of
other functions
§ IEC 61850 Information Model is being updated
§ IEEE 2030.5 (Smart Energy Profile 2) communication protocol is being
expanded
§ IEEE 1815 (DNP3) SCADA protocol is adding Profiles for DER
April 8, 2015 www.eqlenergy.com / 28
29. DRP Process: “More Than Smart (MTS)”
Working Group

§ Provide an open, voluntary stakeholder forum to discuss core
issues
Objectives:
§ Define common parameters for the development of distribution planning
scenarios
§ Identify and define the integrated engineering-economic analysis required to
conduct distribution planning in the context of AB 327 requirements
§ Identify the considerations to meet customers’ needs and California’s policy

Essential Recommendations
Develop
long
term
distribution
planning
roadmaps
ü Use Open Stakeholder process for roadmap
ü Include if and when formal DRPs are necessary for which locations
ü Include risk assessments of technologies and reliability of resources
Do
not
re-‐invent
what
has
already
been
achieved
ü Use existing DRP costing methodology, as applicable
ü Follow SIWG technological requirements and IEEE 1547 standard
ü Use existing integration and communication standards for interoperability
Address
cost
allocation
early
ü Focus on “least regrets” solutions
ü Enhance market equitability (“fairness”) over time (not just the last DER)
ü Provide pricing and investment stability
ü Minimize technological obsolescenceApril 8, 2015
