Surrebuttal Testimony of Devi Glick on SCEG Fuel Costs
Dr. Asa Hopkins provided testimony before the District of Columbia PSC on behalf of the DC Department of Energy and Environment. Altagas proposed to acquire the District’s gas distribution utility, and Dr. Hopkins testified regarding the suitability of Altagas as a purchaser in light of DC’s goals for greenhouse gas emissions reductions. His testimony included an analysis of the long-term potential for natural gas consumption in the District in the context of an 80 percent GHG emissions reduction across all sectors, and concluded that dramatic reductions in fossil fuel gas consumption are going to be necessary, that renewable natural gas supplies are unlikely to make up the difference, and that WGL would need to change aspects of its business model as the city moves toward its goals. Dr. Hopkins testified regarding the suitability of Altagas’s merger commitments to the District’s GHG goals in light of these conclusions.

Wild fires rage in California. Communities continue rebuilding after devastating storms. The next financial crisis could lurk around the next corner. Worst-case scenarios are happening, but the current public policy framework leaves communities defenseless against them.
On December 21, 2017, we celebrated the release of Worst-Case Economics: Extreme Events in Climate and Finance, the latest book by Frank Ackerman (Synapse Principal Economist). Dr. Ackerman joined Bruce Biewald for our Third Thursday webinar series to discuss his new book, which Juliet Schor described as "highly accessible but profound" and Samuel Bowles called "an important book and a delight to read."
Here's a brief description from Dr. Ackerman:
The stock market and the climate are well-behaved most of the time – but those are not the times we worry about. Worst-case scenarios are all too real and all too common. The financial crisis of 2008 was not the first or the last to destroy jobs, homeownership and savings for millions of people. Ever-weirder weather includes megastorms clobbering communities from New York to Bangladesh, rising sea levels, and heat waves killing thousands across Europe.
Climate and financial crises are serious events, requiring vigorous responses. Yet public policy is trapped in an obsolete framework with a simplistic focus on average or likely outcomes rather than on dangerous extremes. What would it take to create better analyses of extreme events in climate and finance, and an appropriate policy framework for worst-case risks? Worst-Case Economics offers accessible and surprising answers to these crucial questions.

Pepco Holdings Inc. has proposed to build a new substation in the Mt. Vernon area in Washington, DC at a cost of over $150 million. Synapse analyzed the area to determine whether the proposed substation is required to maintain reliability. In the resulting report, Synapse demonstrates how non-wires alternatives such as energy efficiency, distributed generation, demand response, or storage could maintain reliability at a much lower cost.
Synapse Energy Economics joined with Sustainable Energy Advantage (SEA), as well as members from NECEC, Mass Energy Consumers Alliance, E4theFuture, and other organizations to analyze the current state of regional renewable portfolio standards in light of many of new policy actions that have been put into place over the last several years. These policy actions include new legislation requiring long-term contracting for renewables and other resources in Massachusetts, Connecticut, and Rhode Island, revised incentives for distributed generation resources, changes to RPS polices in other states in New England, proposed Massachusetts-specific CO2 caps, and newly-revised forecasts for electricity sales that take the full impact of new energy efficiency measures into account.
Since 2005, Synapse has provided analysis of New Jersey's Basic Generation Service (BGS) procurement options for the New Jersey Division of Rate Counsel. The BGS procurement process includes annual auctions held by the State of New Jersey for the procurement of fixed-price, basic electric generation service (BGS-FP). BGS-FP service is the name of the rate plan for those residential and small commercial customers who choose not to use a competitive supplier for their electricity needs. Synapse's BGS procurement analysis takes into consideration the BGS auction process and other factors relevant to procurement options for NJ BGS customers. Synapse's analyses include assessment of procurement options in other states; futures markets for electricity, natural gas, and coal; recent auction/RFP results for BGS-FP-equivalent services from other states; PJM technical issues affecting BGS procurement considerations; and other relevant issues. Based on its analysis of the 2017 proposal, Synapse recommended that the BGS process should not move away from procuring a fixed price product that was meant to protect ratepayers form market volatility to a product that slowly increases protection for bidders at ratepayers’ expense.
On behalf of Consumers for Sensible Energy and a number of other non-governmental organizations, Synapse analyzed the need for, and the cost of, the Access Northeast (ANE) natural gas pipeline. As proposed, the ANE pipeline relies on a new funding mechanism whereby electric ratepayers would pay for new gas pipelines. This unprecedented funding proposal has spurred controversy and litigation: the Massachusetts Supreme Judicial Court and the New Hampshire Public Utilities Commission both rejected this approach, declaring that it violates state laws enacted to restructure the electric utility sector and to protect consumers from undue financial risk. Pipeline proponents claim that the ANE pipeline is needed to relieve capacity constraints on New England’s natural gas pipeline system and that the cost of the pipeline is justified because it will ultimately save money for New England electric ratepayers.
Synapse’s analysis showed otherwise. Any savings created by the ANE pipeline are likely to be outweighed by its costs, which are more than twice what proponents have generally reported. The analysis also indicated that the need for natural gas in New England will decrease dramatically within a few years of ANE’s construction. This would alleviate the capacity constraints cited to justify the pipeline. Synapse modeled energy use, prices, and emissions in a base scenario in which there is no new pipeline compared to a scenario in which the ANE pipeline is constructed.
New England's Shrinking Need for Natural Gas
Synapse’s Rachel Wilson provided analysis and testimony on an Avista Corporation rate case before the Washington Utilities & Transportation Commission. Ms. Wilson evaluated Avista’s production cost modeling, which used the AuroraXMP model, to determine if its requested increase in power costs was reasonable. She found that Avista’s modeling methodology led to a sustained overestimate of annual power supply costs, as evidenced by the compounding of credit deferral balances in its Energy Recovery Mechanism. Ms. Wilson recommended that Avista recalibrate its modeling to allow the Energy Recovery Mechanism to function as intended—to capture the variability between modeled and actual power supply costs. She further recommended that Avista more fully explore the possibility of joining the Western Energy Imbalance Market, which is a real-time wholesale energy market in which participants can buy and sell energy when needed.
Synapse developed a comprehensive framework for balancing the growth of distributed solar with customer protection. Rooted in fundamental ratemaking and long-term resource planning principles, this framework enables regulators, consumer advocates, and other stakeholders to assess the merits of distributed solar against its potential for inequitable cost-shifting from solar customers to non-solar customers. The framework is grounded in addressing the three key questions that regulators should ask regarding any potential distributed solar policy: (1) How will the policy affect the development of distributed solar? (2) How cost‐effective are distributed solar resources? and (3) To what extent does the policy mitigate or exacerbate any cost‐shifting to non‐solar customers? Answering these questions will enable decision‐makers to determine which policy options best balance the protection of customers with the promotion of cost‐effective distributed solar resources. This report describes the analyses that can be used to answer these questions.
The Southwest Energy Efficiency Project (SWEEP) conducted a study on benefits of residential heat pumps for space heating and water heating in five major cities in the Southwest. Kenji Takahashi of Synapse Energy Economics played a key advisory role assisting SWEEP with conducting the first major analysis of heat pumps against natural gas heating in the region. More specifically, he reviewed, advised, and offered recommendations on key assumptions and methodologies for evaluating energy, economic, and emissions impacts of heat pumps.

In 2014-2015, Berkshire Gas in Massachusetts placed a moratorium on new services in part of its territory after identifying distribution capacity constraints and insufficient supply resources. On July 8, 2016, Berkshire Gas filed a petition with the Department of Public Utilities seeking approval of its Long-Range Forecast and Supply Plan (F&SL) under D.P.U. 16-103. The company based its plan on analysis of various resource options to increase access to natural gas for the region as a precursor to lifting the moratorium.
On behalf of the Town of Montague, Synapse reviewed and assessed the reasonableness of Berkshire Gas’s F&SL. Our review of the resource plan revealed that while the plan included energy efficiency and demand response as options, it gave little attention to such resources. Instead, the company recommended investment in extensive and expensive new infrastructure options. We concluded that the company could lift the moratorium by implementing a few simple steps: (a) re-establish curtailable agreements with two large customers that already have dual-fuel capability, and (b) change the way it estimates impacts from current and future energy efficiency programs. We also identified additional demand-side resource potential by analyzing the historical performance of gas energy efficiency programs in New England, current program offerings, and a new gas demand-response program based on internet-connected thermostats. Our analysis concluded that with these expanded demand-side resources, the company could expect future peak load to decline from today’s level over the next five years. Furthermore, the future load forecast could be even lower if it incorporated potential impacts from emerging technologies and other factors. Specifically, electric heat pumps and the state’s existing climate change policies are highly likely to lead to substantial electrification in various sectors and to lower overall gas consumption.
Using Demand-Side Resources to End a Moratorium on New Customers for a Local Natural Gas Company in Massachusetts
Synapse prepared a summary of best practices in utility demand response (DR) programs and then compared those practices with HydroQuebec Distribution's planned DR resource and programs in their 2017-2026 Supply Plan, resulting in a set of recommendations for programmatic activities and revised planning processes. Synapse produced an expert report as well as a presentation used during live testimony.

In February 2017, the utilities with ownership of Navajo Generating Station in Arizona voted to cease operations of the coal-fired power plant. Two months later, Peabody Energy, operator of the mine that supplies fuel to Navajo, presented an analysis before the Arizona Corporation Commission demonstrating that Navajo is economically viable. On behalf of Sierra Club, Synapse examined this study, which was commissioned by Peabody and conducted by Navigant. Synapse found that Navigant relied on overstated market energy prices and understated Navajo's fuel prices, resulting in nearly $2 billion in errors.
The Los Angeles City Council has mandated that the Los Angeles Department of Water and Power (LADWP), the largest municipally-run utility in the United States, analyze powering 100 percent of demand with renewable energy. To date, LADWP's efforts have been insufficient, as the utility has only published an analysis of a slight increase over current renewable energy targets and is not planning to finalize their 100 percent renewable study until 2020 at the earliest.
Food & Water Watch engaged Synapse to analyze a potential pathway to 100 percent clean energy in Los Angeles by 2030. In our study, we found that it is possible for LADWP to exclusively use renewable resources to power its system in every hour of the year. What's more, we found that under one of the clean energy pathways analyzed, the transition to 100 percent renewable energy in every hour of the year can occur at no net cost to the system. The resulting report, Clean Energy for Los Angeles, provides a roadmap for how to achieve 100 percent renewables by integrating and harnessing renewable energy more efficiently and investing in additional efficiency, storage, and demand response.
Although the report only focuses on a single city, the results are important and applicable to many other parts of the country. Los Angeles's 4 million residents make the city larger than 22 entire states, while the annual energy served by LADWP is greater than sales in 13 individual states, indicating that if this transition is possible in Los Angeles, it is feasible in other parts of the country as well.
Synapse was engaged by Riverkeeper and the Natural Resources Defense Council (NRDC) to analyze replacement energy and capacity resources associated with the retirement of the Indian Point Energy Center (IPEC). Synapse utilized the National Renewable Energy Laboratory ReEDS modeling system to estimate an economically optimal expansion of renewable energy resources in New York that would (i) meet Clean Energy Standard (CES) requirements; (ii) achieve required energy and capacity requirements with IPEC retired so as to maintain reliability, and (iii) track the energy production and capacity expansion costs of meeting all New York State requirements during the period 2016 to 2030. Our analysis found that the most cost‐effective replacement resource scenario includes an increase in the level of energy efficiency procurement in New York State above and beyond assumed CES levels, towards the most aggressive, achievable energy efficiency levels that NYSERDA and New York utilities can achieve. Increased levels of energy efficiency investment—and clear direction from the Public Service Commission to ensure those levels in fact materialize—will reduce the cost of achieving the CES’s 50 percent by 2030 renewable energy requirement.
Synapse evaluated an "Empower Kentucky" plan on behalf of Kentuckians for the Commonwealth. Synapse worked closely with stakeholders in Kentucky to develop inputs to be used in modeling, then used NREL's Renewable Energy Deployment System (ReEDS) and IMPLAN, to evaluate a business-as-usual future and an Empower Kentucky future in which Kentucky embraces energy efficiency, renewables, and a carbon price. Through this analysis, Synapse found that an Empower Kentucky future would produce significant benefits in emission reductions, residential bill reductions, and increases in jobs for Kentuckians.
On behalf of the Illinois Office of the Attorney General, Synapse reviewed Commonwealth Edison Company’s (ComEd) proposal for a voltage optimization validation project within the context of ComEd’s formula rate proceeding. Principal Associates Max Chang and Bob Fagan submitted testimony before the Illinois Commerce Commission (Case 16-0259) addressing ComEd’s planned Voltage Optimization Validation Program and its opportunities for data analytics. Synapse’s analysis found that ComEd’s validation study did not adequately demonstrate that the program would address the company’s challenges. Mr. Chang and Mr. Fagan recommended that the Commission direct ComEd to adopt a more comprehensive and robust validation study for voltage optimization. Mr. Chang and Mr. Fagan also recommended that the Commission require ComEd to provide information regarding the development of a long-term plan to fully utilize data gathered from the installation of smart meters and modern distribution infrastructure.
Synapse analyzed the impacts of increasing the Connecticut Renewable Portfolio Standard.
In 2016, Synapse provided a report estimating the net savings for a typical car and light truck owner associated with compliance with proposed federal fuel economy standards for 2025. In March 2017, Synapse conducted additional analyses addressing automaker claims that the fuel economy standards hurt households and affordability of new vehicles. We found that actual fuel economy improvement in the last ten years has saved households’ bottom line.

Sierra Club retained Synapse to review Dayton Power and Light’s (DP&L) application for approval of an electric security plan (Cases No. 16-0395-EL-SSO, 16-396-EL-ATA, and 16-397-EL-AAM). Synapse’s review focused on DP&L’s proposed Distribution Modernization Rider (DRM) and the value and outlook of the Company’s coal fleet. The proposed DRM would charge ratepayers $145 million per year over seven years. These charges would subsidize risky capital investments in the Company’s coal assets—several of which have been determined by other owners to have value and be unreliable. On behalf of Sierra Club, Tyler Comings submitted testimony to the Public Utilities Commission of Ohio demonstrating the coal fleet’s low value and poor reliability and recommending that the Commission deny the DMR.
Synapse launched a report in the fall of 2018 examining the technology options and impacts for building decarbonization in California, with a primary focus on air source heat pumps for space and water heating. The report examines electric grid impacts as well as the impact on customer economics. This included a detailed comparison of customer economics under different existing and near future rate structures. The report concludes with a set of recommended actions, including policy changes, to accelerate market transformation in the building sector.
Synapse reviewed assumptions in Delmarva Power and Light’s benefit-to-cost analysis of its Advanced Metering Infrastructure (AMI) Initiative. Max Chang submitted testimony on behalf of Maryland OPC demonstrating that, due to unreasonable assumptions, DPL overestimated the benefit to cost ratio of the AMI program for the 2015-2024 period. Mr. Chang recommended that the Commission disallow $34 million in order to protect ratepayers.
On behalf of the Office of the People's Counsel for the District of Columbia (OPC), Synapse evaluated several aspects of distributed generation in Washington, DC. This project consisted of three research topics. First, Synapse researched and offered recommendations regarding policies that can sustainably support the development of distributed generation in the District, while avoiding adverse consequences. Second, Synapse assessed the technical and economic potential for distributed generation in the District, particularly solar photovoltaics (PV). Finally, Synapse conducted a benefit-cost analysis of solar in the District.
OPC Reply Comments Regarding Pepco Comments on Value of Solar Study
Synapse was retained by Earthjustice to draft a whitepaper discussing grid resiliency issues in the context of the United States Department of Energy (DOE)’s “grid resiliency pricing rule” proposal. DOE’s proposal directed the Federal Energy Regulatory Commission (FERC) to design rules that would guarantee full recovery of costs for all generating units operating in competitive wholesale markets with 90 days of fuel supply on-site (conventionally understood to refer to nuclear and coal-fired units). Synapse’s whitepaper discusses several key problems associated with this proposal: first, the authorities in charge of the nation’s wholesale energy markets (including FERC itself as well as ISO/RTOs and state agencies) have devoted substantial efforts to increasing the reliability and resiliency of the grid system and have reasonable, market-based approaches for accomplishing this goal. Second, fuel supply disruptions have not historically been a significant cause of service interruptions. Third, coal units in particular are vulnerable to both fuel supply disruptions and other failures during extreme weather and temperature events, and have demonstrated decreasing reliability over time. Synapse’s whitepaper was filed under FERC docket RM18-1-000 in support of comments submitted by Earthjustice, Environmental Defense Fund (EDF), Natural Resources Defense Council (NRDC), Sierra Club, Sustainable FERC Project, the Union of Concerned Scientists (UCS), the Center for Biological Diversity, the Environmental Law and Policy Center, the Southern Environmental Law Center (SELC), Conservation Law Foundation (CLF), Environmental Working Group, and Fresh Energy.
