January 2017

In January 2017, the California Air Resources Board (CARB) issued their proposed plan to achieve the most ambitious reduction in greenhouse gases in North America - a 40% reduction below 1990 levels by 2030 - as required by state law (AB32, 2006 and SB32, 2016). Over the past year, E3 has worked closely with ARB to model the energy costs and greenhouse gas mitigation impacts associated with the proposed plan, known as the 2017 Climate Change Scoping Plan Update.
E3 used its California PATHWAYS model to estimate the combined effects of existing and proposed GHG mitigation policies. This economy-wide energy system stock rollover model captures the interactions between GHG measures such as electric vehicles, energy efficiency and renewable electricity, while simulating the corresponding changes to hourly electricity system operations. The PATHWAYS annual capital costs and fuel costs and savings associated with the Proposed Scoping Plan scenario were also used by ARB to estimate the macroeconomic impacts of meeting the state's climate goals.
The ARB's 2017 Climate Change Scoping Plan Update, as well as the version of E3's PATHWAYS model that was developed to support the analysis and supporting documentation, are all publicly available on the ARB's website. The press release and links to supporting materials is here: https://www.arb.ca.gov/newsrel/newsrelease.php?id=891

April 2016

E3's recently released "Full Value Tariff Design and Retail Rate Choices" Report, sponsored by New York State Energy Research and Development Authority Department (NYSERDA) and NY Department of Public Staff, proposes a practical 'full value' tariff (FVT) and explores transition paths that can be used for its implementation. To evaluate the effects of a FVT, a New York-specific 'smart home' model was developed to evaluate customer behavior and the value proposition of key DER technologies that can potentially respond to dynamic prices sent through retail rates such as those under existing default rates, existing time-of-use (TOU) rates, and the proposed FVT or 'smart' rates that are more area- and time-specific. Solar PV, air conditioning energy efficiency, customer conservation, smart heating/cooling, and smart charging of electric vehicles were all evaluated.

January 2016

E3 recently completed an assessment of the flexibility of the generation fleet of the Western Interconnection under a range of renewable penetrations. The full report and executive summary can be accessed here The study examines the operational consequences of continuing to add variable renewable resources (wind and solar) in excess of current policy targets, as well as strategies to mitigate the challenges that arise at higher penetrations. The results of the study will be shared in a webinar hosted by WECC on January 27

E3's work on technology pathways to a low-carbon energy system is having a significant international impact. E3 chief scientist Dr. Jim Williams is director of the Deep Decarbonization Pathways Project (DDPP), a consortium of researchers that has developed low-carbon blueprints for each of the 16 highest-emitting countries. The importance of this work in moving the international climate policy discussion toward concrete solutions was highlighted in a featured article in the New York Times during the recent UN climate summit in Paris. The DDPP's example had a strong influence on the Paris agreement itself, which calls for all countries to develop deep emission reduction strategies and share them transparently.

The DDPP research team for the US, led by E3 in collaboration with scholars from UC Berkeley, Lawrence Berkeley Lab, and Pacific Northwest National Lab, has produced an influential two-volume study of decarbonization pathways in the US. This study is the basis of a macroeconomic analysis by ICF International showing the potential benefits of deep decarbonization for the US economy, and was also cited by the Union of Concerned Scientists in a recent open letter to US presidential candidates urging aggressive action on clean energy.

October 2015

On October 30, Nick Schlag and Arne Olson of E3 presented Western Interconnection Flexibility Assessment results from the WECC Flexibility Assessment at the Joint CREPC-SPSC-WIRAB Meeting in San Diego. The WECC Flexibility Assessment investigates the impacts of high penetrations of renewable resources in the West upon operations and the implications of these changes for flexibility planning. The results of the study reinforce many conclusions that have been reached by prior studies of renewable integration, most notably: (1) renewable curtailment becomes a necessary tool to provide reliable at high penetrations, and (2) improved regional coordination can mitigate operational challenges under high penetrations. A final report on the study will be released in December.

August 2015

Dr. Nancy Ryan, E3's Senior Director of Policy and Strategy, addressed the Advanced Energy Economy (AEE) 2015 California event. Speaking to an audience of 300 professionals from clean energy companies, utilities and regulatory agencies, Dr. Ryan highlighted key findings from E3's recent analysis for Governor Brown and his Energy Principals on California Pathways: Long-Term Greenhouse Gas Reduction Scenarios for California. The main message of our work, she explained, is that meeting Governor Brown's goal of reducing California's GHG emissions to 40% below the 1990 level is feasible with technologies that are available today. Nor is it necessary to sacrifice the reliability of our electric system or our lifestyles and living standards. What is daunting, Dr. Ryan observed, is the scale and scope of the transformation of California's economy. Four key transformations are needed in the energy system by 2030: doubling the current rate of energy efficiency improvements, increasing renewable energy's share of our electricity supply to at least 50%, electrification of vehicles and equipment, and replacing fossil fuels with biofuels of decarbonized gas. This transformation will open huge new markets for the clean tech companies leading the way to the advanced energy economy. With this opportunity comes the challenge to offer products that are not just cleaner than today's options, but are also cheaper and better quality, so they become the natural choice for consumers. E3 was proud to be a Gold level sponsor for the AEE event.

The U.S. Environmental Protection Agency (EPA) just released the final version of its Clean Power Plan, a rule that uses section 111d of the Clean Air Act to reduce greenhouse gas emissions from the nation's electric sector. E3 consultants Lucy McKenzie, Ren Orans, Jim Williams and Amber Mahone in December 2015 authored Strengthening the Clean Power Plan: Three Key Opportunities for the EPA, an Electricity Journal piece outlining three key opportunities for the EPA to strengthen the Plan, spread the burden more equitably amongst states, and put the nation on the path to necessary emissions reductions by 2050. Many of the changes in the EPA's final rule are consistent with E3's recommendations, and E3 looks forward to working with stakeholders and states as they plan for compliance and the energy transitions ahead.

On May 13, E3 Chief Scientist Dr. Jim Williams gave an invited talk on "Deep Decarbonization of the United States" in the Chair's Lecture Series at the California Air Resources Board. The talk was based on a recent landmark study by E3, LBNL, and PNNL, which featured a detailed sector-by-sector, region-by-region, year-by-year analysis of the infrastructure changes, technology requirements, and costs of reducing U.S. greenhouse gas emissions 80 percent below 1990 levels by 2050. On March 26, Dr. Williams also spoke on this subject to a sold-out audience at the Commonwealth Club in San Francisco; a podcast of this talk is available here.

On May 6th, E3 presented at a workshop held in New Delhi the results of a study identifying business models for rooftop solar and other distributed energy resource models for the Tata Power Delhi Distribution Limited (TPDDL) The workshop was attended by several regulators, developers, financial institutions, non-profits and research organizations, including the Delhi Electricity Regulatory Commission. The study identifies the value of rooftop solar over time and illustrates how TPDDL is positioned to overcome the challenges to solar market growth. Complementary benefits of other DER (namely energy efficiency and demand response) are identified and alternative policies to Net Energy Metering that can mitigate cross-subsidies in the long term are shown. E3 described how India's relatively young rooftop solar industry can leapfrog beyond western countries in terms of interconnection processes, attention to monitoring and quality control, and incentive structures. The workshop was led by Dr. Priya Sreedharan and Ms. Amy Wagner of E3 and officiated by Mr. Praveer Sinha, CEO and Executive Director of TPDDL. The study is expected to be released publicly by early June.

April 2015

E3 created a public tool to evaluate the impacts of a successor to the existing net energy metering (NEM) tariff for eligible renewable customer-generators for the CPUC. The tool was created in response to Assembly Bill (AB) 327 (Perea) that directs the Commission to develop a standard tariff or contract for renewable customer-generators that ensures that customer-sited renewable generation continues to grow sustainably and that the total benefits to all customers are approximately equal to the total costs. The Public Tool produces SPM cost-test results and distributed energy resource (DER) adoption forecasts under different user-defined policy scenarios, rate designs, and NEM successor tariffs. More information is available here.

March 2015

A growing number of auto-makers have introduced plug-in electric vehicles in California and other markets. Industry observers generally agree that ready availability of charging infrastructure is crucial to realize widespread consumer adoption. Utilities are well suited to facilitate vehicle electrification, but few have progressed beyond small-scale pilots. In a new paper "Engaging Utilities and Regulators on Transportation Electrification" Dr. Nancy Ryan and Luke Lavin of E3 present the case for increased utility engagement, demonstrating that electrification of passenger vehicles could benefit utility customers, shareholders, and vehicle drivers.

E3 presented the results of a new greenhouse gas (GHG) reduction study for California's energy and environmental regulators at the UC Davis California Climate Policy Modeling Dialogue. The study was prepared for the California Air Resources Board, California Energy Commission, California Public Utilities Commission, the California Independent System Operator and the Office of Governor Brown. E3 evaluated the feasibility and cost of a range of potential 2030 GHG targets along the way to meeting the state's goal of reducing GHG emissions 80% below 1990 levels by 2050. A PowerPoint report summarizing the scenario results, along with supporting data, are available here.

February 2015

E3 in collaboration with a world class team has released a study, "Assessing the business case for rural solar microgrids in India: a case study approach", funded by a USTDA grant in support of Azure Power, a private solar power developer based in India. E3 was awarded the grant through a competitive process. The project developed the technical and business solutions for AC-based microgrids, using two Indian villages (Bar in Chhattisgarh and Devari Bharat in Uttar Pradesh) as case studies, and presents recommendations and conditions necessary to scale up microgrid solutions more broadly across rural India. The report can be downloaded here. The study was led by Dr. Priya Sreedharan of E3 in collaboration with Humboldt State University's Schatz Energy Research Center, Black and Veatch USA and India, Varesh Energy, Dr. Chris Greacen, Christopher Freitas, and Ranjit Deshmukh. Contributing authors include E3's Ryan Jones, Michele Chait, Dr. Fritz Kahrl and Snuller Price; Black and Veatch's Jagmeet Khangura and Atul Garg; Humboldt State University's Richard Engel, Brendon Mendonca, Tom Quetchenbach, Meg Harper and Dr. Arne Jacobson; Varesh's Shobhit Goel and Varun Aggarwal.

September 2014

Arne Olson and Nick Schlag of E3 will participate in the Western Interstate Energy Board's (WIEB's) upcoming fall meeting in San Diego. Mr. Olson will be a panelist on The System Flexibility Forum on October 20-21. Mr. Olson and Mr. Schlag will present key findings from the E3 report, Natural Gas Infrastructure Adequacy in the Western Interconnection: An Electric System Perspective> at the joint CREPC/SPSC/WIRAB meeting on October 21-22.

Kush Patel of E3 presented on developing a cost-benefit methodology for valuing distributed energy resources (DER) at the August 25-26th conference in Charleston, South Carolina organized by the Electric Cooperatives of South Carolina and the South Carolina Coastal Conservation League. This conference was in response to South Carolina's recently passed legislation, Act 236 or "the Distributed Energy Resources Programs Act" focused on setting targets for DER deployment and compensation over time. Mr. Patel also spoke on several panels providing guidance and lessons learned from E3's recent experience in performing DER cost-benefit studies in California, Hawaii, and in Nevada. E3 has been retained by the South Carolina Office of Regulatory Staff (ORS) to develop and evaluate the costs and benefits of the utility proposed DER programs in the state, such as net metering, incentives, and 3rd party ownership.

August 2014

E3 and DNV GL completed the second phase of their investigation into the adequacy of gas infrastructure to meet the needs of the electric sector in the Western Interconnection. The results of the study Natural Gas Infrastructure Adequacy in the Western Interconnection: An Electric System Perspective conducted for the Western Interstate Energy Board (WIEB) are summarized in Natural Gas Infrastructure Adequacy in the Western Interconnection: An Electric System Perspective, Phase 2 Report. Phase 2 focused on the question: Will the gas system have adequate short-term operational flexibility to meet increased volatility in hourly electric sector natural gas demand due to higher penetrations of variable renewable resources in the Western Interconnection? The purpose of the study investigation is threefold: (1) to focus the regional dialogue on the most important gas-electric coordination issues; (2) to assess the magnitude of any potential limitations of gas infrastructure to support the future demands of the electric sector in the regions evaluated; and (3) to provide guidance to policymakers, regulators, pipeline companies, utilities, generators, and electric sector planners on actions that may be needed to overcome potential challenges resulting from the increasing reliance on natural gas for power generation. This study is intended to provide a bridge between the two industries in the Western Interconnection, to foster communication and to educate participants on both sides of the gas-electric interface in a region where dialogue has, to date, been limited.

July 2014

Eric Cutter, Ben Haley, Jim Williams and C.K. Woo of E3 were coauthors on a recent article describing a water-energy avoided cost framework; also published online in the Electricity Journal. Energy embedded in the provision of water has been the subject of numerous water-energy nexus studies that are nearly unanimous in recommending integrated evaluation of energy and water savings from demand-side management (DSM). Joint implementation of DSM, however, remains a rare exception. The recommendations and tools developed to date are either overly broad or too specific to readily implement across multiple utilities. In this article, we link a forward-looking marginal water supply approach and the well-established energy avoided cost framework to jointly value water and energy efficiency savings. As a case study set in the San Francisco Bay Area of California, we evaluate cold water, hot water and energy efficiency measures. Avoided costs for water are far more impactful than embedded energy for efficiency measure cost-effectiveness. While several measures fail cost-effectiveness tests when viewed from an energy or water utility perspective alone, they pass under an integrated approach. Thus, the integrated approach supports rational cost sharing between energy and water utilities and facilitates cooperation and increased funding for DSM.

E3 has played a leading role in a new landmark study of what is technically required to deeply reduce global greenhouse gas emissions. "Pathways to Deep Decarbonization," prepared by research teams from the fifteen highest emitting countries, was presented on July 8 to U.N. Secretary General Ban Ki-moon in advance of international climate negotiations to take place in Paris in 2015. "This is exactly the kind of practical problem-solving that we need to tackle climate change," Secretary General Ban said. E3's Dr. Jim Williams, Dr. Fritz Kahrl, Jack Moore, and Ben Haley performed the U.S. analysis, identifying multiple technically feasible pathways to reduce U.S. emissions more than 80% by 2050. A follow-up economic analysis is in progress. The study has been widely cited in the press, including this article in the New York Times.

June 2014

E3 wrote a paper "Valuing Energy Storage as a Flexible Resource" that was submitted as comments in the CPUC Proceeding A. 14-04-006 summarizing key issues of the potential benefits of energy storage for consideration in the applications of PG&E, SCE and SDG&E for approval of their respective energy storage procurement framework and programs. The paper uses results from the E3 study "Investigating a Higher Renewables Portfolio Standard (RPS) in California" and subsequent REFLEX modeling work to demonstrate why curtailment of renewable generation is a substantial and quantifiable benefit that should be considered in valuing the relative benefits of both short- and long-duration energy storage. The overarching themes of this report are that a cost-effectiveness framework for energy storage should: a) include not just existing markets and avoided costs, but also the future benefits of reducing renewable curtailment under higher RPS levels, b) describe how the relative costs, benefits and tradeoffs of short- vs. long-duration solutions will be quantified and evaluated and c) include system level and portfolio costs and benefits.

E3 has been selected by the Tata Power Delhi Distribution Limited (TPDDL), a leading electricity distribution company in India, to develop a distributed energy resource (DER) plan for its service territory in north Delhi. The project is being supported by a grant to TPDDL from the U.S. Trade and Development Agency (USTDA). The project will consider solar, demand response, storage and other DER and will enable TPDDL to prioritize and deploy resources that will improve the reliability of its electricity network, reduce emissions, and lower overall power costs for its more than six million customers. Mr. Snuller Price, Dr. Priya Sreedharan and Ms. Amy Guy Wagner from E3 will work closely with Mr. Praveer Sinha, CEO and Mr. Arunabha Basu, Chief of Technology and Systems of TPDDL. Special emphasis will be given to assessing the financial and technical viability of power generation from renewable energy resources, the integration of demand response technologies on TDPPL's network, and the development of specifications for a pilot project. This study responds directly to TDPPL's goal of generating cleaner, more reliable electricity, while also positioning U.S. firms to provide technology solutions. This project supports bilateral U.S.-India government priorities, including increasing domestic energy production and implementing smart grid solutions, as identified during the ongoing U.S.-India Energy and Strategic Dialogues.

E3's Director of Policy and Strategy, Dr. Nancy Ryan, a former member of the California Public Utilities Commission, joined current Arizona and Hawaii Commissioners on a panel at the June 2014 Western Conference of Public Utility Commissioners in Seattle. Dr. Ryan shared her views on California's lessons learned from its current Renewables Portfolio Standard (RPS) program and provided insights into challenges the state must overcome as it goes beyond the current 33% RPS target. Dr. Ryan's main message to the western commissioners was that the region can realize a renewable future cost-effectively by building integration solutions into portfolios from the ground up. Dr. Ryan presented findings from E3's recent study on "Investigating a Higher Renewables Portfolio Standard in California" .

April 2014

Eric Cutter, Ben Haley, Jeremy Hargreaves and Jim Williams of E3 were co-authors on a recent paper "Utility scale energy storage and the need for flexible capacity metrics" to be published in the July issue of Applied Energy. E3 used a mixed integer linear program to optimize the dispatch of three bulk energy storage technologies and a conventional combustion turbine. Each technology was modeled as price-takers, co-optimizing their dispatch first in day-ahead and subsequently in real-time energy and ancillary service markets. Due to their more flexible operating characteristics, energy storage technologies earn much higher net revenues than CTs and participate more in the DA markets where most ISO procurement occurs. Our results show that the traditional cost of new entry (CONE) is no longer an adequate cost metric when flexibility is of equal or greater concern than peak capacity for long-term planning, as it is in California.

March 2014

Amber Mahone, senior consultant at E3, was invited to present on an energy efficiency panel at ACEEE's 2014 National Symposium on Market Transformation, on March 31st in Baltimore, MD. Ms. Mahone discussed ways to create a portfolio of energy efficiency measures that balances the need for short-term savings with long-term energy efficiency gains. Her presentation discusses the role of the societal cost test in valuing long-term energy efficiency, and draws from E3's work on achieving long-term greenhouse gas reductions in California.

E3 and DNV GL completed the first phase of their investigation into the adequacy of gas infrastructure to meet the needs of the electric sector in the Western Interconnection. The results of the study conducted for the Western Interstate Energy Board (WIEB) are summarized in Natural Gas Infrastructure Adequacy in the Western Interconnection: An Electric System Perspective. Nick Schlag and Arne Olson of E3 presented the study's findings at the Committee on Regional Electric Power Cooperation and State-Provincial Steering Committee (CREPC/SPSC) meeting on March 25, 2014 in Tempe, Arizona.

E3 helped the Port of Long Beach, the second-busiest port in the nation, obtain electric rate discounts and a program under which Southern California Edison (SCE) installs major electric infrastructure at no cost to the Port or its tenants. These measures will support critical electrification and environmental improvement projects at the Port, improving air quality in the region. The rate discounts are expected to total $350 million over the next 24 years, equating to a savings of about 15%. E3 Senior Consultant Michele Chait led electric rate negotiations for the Port of Long Beach.

Nancy Ryan, E3's Director of Policy and Strategy, was invited to address the March 11 meeting of the Plug-in Electric Vehicle Collaborative in San Diego, California. Regulators, utilities, automakers and other stakeholders come together in the collaborative to share insights and experiences on the roll-out of plug-in electric vehicles in California. Dr. Ryan presented findings from E3's recent study on Investigating a Higher RPS in California, highlighting the implications for the PEV market, charging infrastructure, and public policy.

February 2014

Dr. Ren Orans, Dr. C.K. Woo and Jenya Kahn-Lang of E3 were co-authors on a recent paper "Are Residential Customers Price-Responsive to an Inclining Block Rate? Evidence from British Columbia". In this article where BC Hydro's bimonthly billing data is used, the authors document statistically significant price elasticity estimates to provide BC Hydro with the support for using a residential inclining block rate (RIB) as a tool for energy conservation.

Texas's wholesale electricity market has undergone major regulatory changes over the past two decades. E3 Senior Partner Dr. C.K. Woo and co-authors Jay Zarnikau - an adjunct professor at the LBJ School, and Ross Baldick - an electrical engineering professor at the University of Texas at Austin, recently published an article "Did the introduction of a nodal market structure impact wholesale electricity prices in the Texas (ERCOT) market?" in the Journal of Regulatory Economics (http://link.springer.com/content/pdf/10.1007%2Fs11149-013-9240-9.pdf), analyzing how the transition from "zonal" to "nodal" markets in Texas, which became functional in December 2010, has affected prices. The analysis finds that the change in Texas's electricity market structure resulted in about a 2% drop in prices controlling for other factors such as natural gas prices, total system load levels, dispatchable generation levels, the treatment of local congestion costs, and the treatment of the revenues received by the market from the auctioning of transmission rights.

January 2014

In an ambitious, forward-looking study jointly sponsored by California's five largest electric utilities, E3 evaluated the operational challenges, potential solutions, and cost consequences of a higher Renewables Portfolio Standard (RPS) in California by 2030. The study benefited from technical input from the CAISO as well as independent review from a distinguished four-member advisory panel. The study utilized E3's first-in-class Renewable Energy Flexibility (REFLEX) model on ECCO International's ProMaxLT production simulation platform. The report and associated materials are available at Investigating a Higher Renewables Portfolio Standard in California.

December 2013

Dr. Jim Williams and Dr. Fritz Kahrl of E3 joined with Orville Schell of the Asia Society and Trevor Houser of the Rhodium Group to develop a roadmap to advise California state government how best to work in collaboration with China to reduce the risk of climate change. Dr. Williams was a co-convenor of the Asia Society's inaugural meeting with many leading China energy and air pollution experts held on December 20 in San Francisco.

Dr. Jim Williams, Dr. Elaine Hart, Ben Haley, and Snuller Price presented their work on the PATHWAYS model, a tool developed at E3 for analyzing the technology requirements and cost of a low carbon transition, at the California Climate Policy Modeling (CCPM) Forum at U.C. Davis on December 16-17. Dr. Williams is on the steering committee of the CCPM.

E3 Partner Arne Olson was an invited speaker at the Harvard Electricity Policy Group's Seventy-Third Plenary Session on December 13, 2013 in Marana, Arizona. Mr. Olson participated in a panel with energy experts from Germany, Spain, Portugal and Belgium, providing a California perspective on the topic Reliance on Renewables: Clash Between Expectations and Reality"

Dr. C.K. Woo, Dr. Priya Sreedharan, Dr. Jeremy Hargreaves, and Dr. Fredrich Kahrl of E3 were co-authors on a recent paper "A review of electricity product differentiation" published in Applied Energy. This review is motivated by our recognition that an adequate and reliable electricity supply is a critical element in economic growth. From a customer's perspective, electricity has several distinct attributes: quality, reliability, time of use, consumption (kW h) volume, maximum demand (kW), and environmental impact. A differentiated product can be formed by packaging its non-price attributes at a commensurate price. The review weaves the academic literature with examples from the real world to address two substantive questions. We concluded that applying product differentiation to electricity can greatly induce end-users to more effectively and efficiently satisfy their demands upon the system, and to do so in an environmentally friendly way.

November 2013

E3 along with the California Center for Sustainable Energy (CCSE) and DE Solutions were selected by the U.S. DOE's Office of Energy Efficiency and Renewable Energy to direct the Pacific Regional Combined Heat and Power Technical Assistance Partnership (CHP-TAP), one of seven regional partnerships. The main purpose of the DOE regional partnerships is to increase the nation's clean energy capacity using cost-effective and energy efficient combined heat and power (CHP) systems. The TAPs promote the development of CHP by providing education and outreach, market development and technical assistance to a variety of stakeholders for evaluating the economic, energy, reliability and environmental value of proposed systems. The Pacific CHP-TAP will focus on CHP development in California, Nevada and Hawaii.

E3 Managing Partner Dr. Ren Orans spoke at the Joint Meeting of the Committee on Regional Electric Power Cooperation (CREPC) and State-Provincial Steering Committee(SPSC) in San Diego, California on October 31, 2013. Dr. Orans presented with Dr. Carl Linvill, Principal at the Regulatory Assistance Project (RAP) to address the Committee's agenda topic "Future Utility Model Fact Finding - What are the Financial Impacts on Utilities?" Dr. Orans' presentation "A customer Side of the Meter Assessment" focused on four case studies of IOUs in the Western Electricity Coordinating Council (WECC) region within the historical context of the utility business model.

September 2013

E3 conducted a study to evaluate the ratepayer impacts of the California net energy metering (NEM) program. This study fulfills the requirements of Assembly Bill (AB) 2514 (Bradford, 2012) [1] and Commission Decision (D.) 12-05-036 to determine "who benefits, and who bears the economic burden, if any, of the net energy metering program," by October 1, 2013. E3 developed three public models to inform the analysis: (1) the E3 NEM Bill Calculator calculates bill savings of NEM customers, (2) the E3 NEM Avoided Cost Model calculates the ratepayer costs that are avoided due to NEM generation, and (3) the E3 NEM Summary Tool combines and displays all of the costs and benefits of NEM. More information about using the E3 NEM Summary Tool can be found in Appendix F of the draft report. Appendix B contains details on the bill calculations, and Appendix C outlines the avoided cost methodology. Read the draft report and view models used to inform the analysis. [1] See Appendix G for further information about AB 2514

Dr. Nancy E. Ryan, who joined E3 earlier this year as Director of Policy and Strategy, was a featured speaker at the Western Power Trading Forum's (WPTF) Western Power Issues Roundtable held in Washington DC on August 9, 2013. Dr. Ryan offered her perspective on prospects for implementing a centralized capacity market in California. Her remarks were grounded in her experience in several high level appointed positions at the California Public Utilities Commission during 2006 to 2013. The WPTF has over sixty member organizations including investment banks, energy traders, merchant generators, utilities and developers from throughout North America.

E3 and Viridity Energy recently issued their Task 6-8 Report "Strategies and incentives for integration of renewable generation using distributed energy resources - A case study based on the University of California, San Diego" for the California Solar Initiative RD&D Project and is now posted on the California Solar Research website. They found that UCSD DER dispatch strategies are technically feasible and can be cost-effective, but current tariff designs inhibit their performance, and net cost-savings are small relative to total campus resource costs. For each renewables integration strategy, they modeled and evaluated the cost-effectiveness of alternative incentive, tariff and resource dispatch cases. Their findings suggest alternative incentive mechanisms and engagement strategies beyond direct load participation and dynamic pricing strategies currently under consideration are needed. See presentation and webinar summarizing their findings.

Dr. Priya Sreedharan of E3 recently returned from field work in remote villages of India with little or no connectivity to existing electrical grids. This field work supported a study being conducted for Azure Power, a solar power developer in India, in which the feasibility of off-grid solar PV microgrids are being explored for rural communities. The work falls under the auspices of a USTDA grant award to Azure. The team met with the community and conducted detailed surveys, and engaged with the state renewable agencies. They explored the opportunities and challenges for solar PV microgrids in these communities. The information collected will be used to complete the development of a business model for these microgrids. The field work was led by Richard Engel of the Schatz Energy Research Center and was supported, in addition to E3, by Varesh Energy of New Delhi.

Dr. Fredrich Kahrl, Gabe Kwok, and Dr. Jim Williams of E3 were co-authors on a recent paper, "Using Natural Gas Generation to Improve Power System Efficiency in China" published in Energy Policy. The paper finds that, although it is commonly argued that natural gas-fired generation is not cost-competitive in China, these arguments ignore the different roles - peaking, load following, and baseload generation - that natural gas generation plays in power systems. Using a detailed generation cost model and a case study from Guangxi Province, the paper argues that natural gas is, in fact, cost-competitive for peaking generation in China, and that using natural gas generation in this role would lead to overall improvements in power system efficiency. The largest barrier to using gas-fired generation for peaking generation in China is generation pricing, which could be addressed through modest reforms to support low capacity factor generation.

Dr. Fredrich Kahrl, Gabe Kwok, and Dr. Jim Williams of E3 were co-authors on a recent paper, "Strategies for Expanding Natural Gas-fired Electricity Generation in China: Economics and Policy" published in Energy Strategy Reviews. Based on a detailed generation cost model, the paper analyzes the changes necessary to increase the share of natural gas-fired generation in China's electricity mix, focusing on load following and baseload generation. While natural gas is not currently cost-competitive with coal for load following and baseload generation, it could become so with policy strategies that lead to relatively modest (10-30%) decreases in relative capital costs and fuel prices, particularly if a small price of around $5 to $15 per tonne CO2 were imposed on CO2 emissions.

June 2013

At Stanford University, E3 Managing Partner Ren Orans, Chief Scientist Jim Williams, and Affiliate Joel Swisher co-taught a winter semester course on electric utiilty planning in the Department of Civil and Environmental Engineering. This unique, first-time course drew 35 graduate students, who learned about planning from experienced experts, and worked together in small groups to conduct their semester projects: complete integrated resource plans for utilities in the western U.S.

February 2013

Dr. C. K. Woo and Dr. Fredrich Kahrl of E3 were co-authors in a recent paper, "What moves wind energy development in China? Show me the money!" published in Applied Energy. This paper finds that the most important drivers of wind energy investment in China are perceived to be those that can have an immediate impact on a wind energy developer's cash flow: government financial assistance, easy and inexpensive transmission access, wind energy cost decline, and a high feed-in-tariff. None of these drivers are directly tied to energy output, which suggests that China's wind energy policies must be modified to incentivize energy output, rather than just installed capacity.

Dr. C. K. Woo and Mr. Gabe Kwok of E3 were co-authors in a recent paper "A Win-Win Mechanism for Electricity Procurement by a Local Distribution Company" published in the Electricity Journal. This paper finds that a time-of-use rate option design allowing a local distribution company's customers to allocate their consumption to be billed at the fixed and daily-varying TOU rates offers a win-win mechanism for electricity procurement in the face of uncertain spot prices and hedging options.

E3 Partner Arne Olson is an invited speaker at the 3 Interconnections Meeting: Facing the Future with Interconnection-wide Planning on February 6, 2013 in Washington, DC. The 3 Interconnections Meeting is sponsored by the National Association of Regulatory Utility Commissioners and the U.S. Department of Energy.

October 2012

E3 Partner Arne Olson was an invited speaker at a biennial meeting of western state energy officials and utility commissions in San Diego, California in October 2012. Mr. Olson appeared on a panel to discuss the "Nexus between distribution and transmission level resource strategies." His talk was entitled "Distributed Generation Benefits and Planning Challenges." He also provided an update on E3's development of an economy-wide carbon accounting tool for use in western regional transmission planning, funded through Lawrence Berkeley National Laboratory.

E3 authors Eric Cutter, C.K. Woo, Fredrich Kahrl and Andy Taylor published the article "Maximizing the Value of Responsive Load" in the August/September issue of the Electricity Journal, arguing that new demands on the grid mean the paradigm for demand response (DR) must shift away from traditional event-based and economic DR. Instead, the focus should be enabling distributed load-based resources to provide dispatchable, flexible, highly responsive and visible control to utility operators, which can provide significant value in integrating renewable and high penetration distributed generation.

July 2012

Dr. C. K. Woo, E3 Senior Partner, has recently been selected as a recipient of the 2012 United States Association for Energy Economics (USAEE) Senior Fellow Award. The award is given to individuals who have exemplified distinguished service in the field of energy economics.

May 2012

Dr. Ren Orans, Managing Partner and founder of Energy and Environmental Economics (E3) was the commencement speaker at U.C. Berkeley's Energy and Resources Group (ERG) May 2012 Commencement. Over the last two decades, Dr. Orans and E3 have been at the forefront of energy and environmental policy in the Western U.S. and Canada, and more recently in China and India. E3 has been a strong supporter of ERG, by offering summer internships, employing students and graduates, and offering the Alexander E. Farrell Graduate Fellowship to support doctoral research.

IEEE Transactions on Sustainable Energy is to publish a paper written by Dr. Jeremy Hargreaves of E3 and Prof. Benjamin Hobbs of Johns Hopkins University entitled "Commitment and Dispatch with Uncertain Wind Generation by Dynamic Programming".
The paper, which will feature in the journal's special wind energy issue, shows the potential for grid operation cost savings when using stochastic unit commitment and dispatch modeling for systems with high levels of wind generation. The study indicates a growing need for stochastic models in system operations as renewables penetration increases.

March 2012

On March 28th, the CPUC released E3's study of the technical potential for, and associated costs of, local distributed PV in California. To be considered "local" in the study, distributed PV must have its output consumed by local load within the area of the substation or feeder to which it is interconnected. The study thus entails detailed assessment of PV interconnection potential by substation for California's 3 large IOUs. The study finds total interconnection potential ranging from roughly 6,000 - 16,000 MW depending on interconnection criteria or rules.

February 2012

E3 has posted a demonstration version of an Energy Storage Cost-effectiveness Tool based on work performed for several clients over the last year. The tool is based in Analytica and accessible on the web via the Analytica Cloud Player. The demo model calculates the costs and benefits for three storage technologies as well as a combustion turbine (LM 6000) under two scenarios: historical 2010 CAISO prices and 2020 CAISO prices taken from the CPUC/CAISO LTPP PLEXOS production simulation model. The model uses the Analytica Optimizer with an hourly dispatch to maximize revenues across multiple markets and benefit categories. (Note: the model is for demonstration purposes only and the results should not be cited).

January 2012

In E3's latest publication, we assess the utility business case for electric vehicles.  Electric vehicles, combined with natural gas fired generation, can result in lower costs to consumers, lower risk to utility shareholders, and lower greenhouse gas emissions than a business-as-usual, coal- and nuclear-dominated scenario.  However, utilities carbon price risk from electric vehicles (EVs) could outweigh the potential benefits of EVs, unless current policies are changed.  The article, Electric Vehicles and Gas-Fired Power: A strategic approach to mitigating rate increases and greenhouse gas price risk by Amber Mahone, Ben Haley, Ren Orans and Jim Williams, appears in the December 2011 edition of Public Utilities Fortnightly.

An E3 team led by Chief Scientist Jim Williams, along with collaborators at Lawrence Berkeley National Laboratory, has published a landmark study of the energy future in the prestigious journal Science. Using California as a case study, the paper provides a detailed assessment of the technology, infrastructure, and cost requirements to deeply reduce greenhouse gas emissions by the year 2050. The study emphasizes the pivotal role of electricity in the transition to a low-carbon economy.

Increasing penetration of wind generation is hypothesized to cause market price divergence between two geographic zones, an indication of market separation due to transmission constraints. Based on an econometric analysis of 15-minute zonal market price data from ERCOT, E3 professionals confirm this hypothesis, thus supporting Texas planned transmission expansion to facilitate the state's projected rapid growth in wind generation. "Wind Generation and Zonal-Market Price Divergence: Evidence from Texas"
