In 2018 and 2019, Synapse surveyed 50 states, the District of Columbia, and Puerto Rico on energy efficiency cost-effectiveness practices and created a public database to summarize and compare state results. The purpose of the Database of Screening Practices (DSP) is to provide information regarding state cost-effectiveness screening practices for ratepayer-funded electric efficiency programs. States can use the DSP to learn from other state’s practices and to readily access and better understand policies, processes, and studies that support assumptions used by states in benefit-cost analyses.

On behalf of the North Carolina Sustainable Business Association, Synapse modeled two scenarios: a "Duke IRP" scenario, which included the Company's planned retirements and additions of more than 9 GW of new gas capacity, and a "Clean Energy" scenario, which included increased penetrations of solar and battery storage technologies. We compared these two scenarios based on energy, capacity, emissions, and impacts to health, rates/bills, GDP, and jobs in North Carolina. Synapse also examined the same impacts for ratepayers in South Carolina on behalf of the South Carolina Solar Business Alliance. The Synapse analyses found that renewable and battery resource options are comparably cost-effective to new natural gas for Carolina ratepayers, and offer other benefits as well.
Modeling Clean Energy for South Carolina: An Alternative to Duke's Integrated Resource Plan
In August of 2018, the U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) released a proposed rule to replace existing vehicle fuel standards. Entitled, Safer Affordable Fuel-Efficient (SAFE) Vehicles Rule for Model Years 2021–2026 Passenger Cars and Light Trucks, or the SAFE Vehicles Rule, the proposed rule would roll back requirements for fuel efficiency mandated in the Corporate Average Fuel Economy (CAFE) Standards.
Synapse examined NHTSA’s and EPA’s vehicle sales and safety analysis, which is presented as a primary motivation for the selection of the standards in the draft rule. NHTSA and EPA estimate that lighter vehicles lead to more vehicle crash fatalities and automakers will be less inclined to reduce the mass of their vehicles if fuel economy standards are less stringent. Further, the agencies indicate that newer vehicles are safer, and more people will buy new vehicles under the draft rule instead of holding onto older vehicles because the cost to buy a new vehicle will be lower.
Our team conducted a literature review and reviewed NHTSA’s and EPA’s vehicle sales and safety modeling. Our analysis found serious flaws in the arguments and underlying analysis and assumptions used by NHTSA and EPA. After correcting these flaws, our analysis showed that increasing fuel economy and GHG standards maintains or even improves vehicle safety, consistent with peer-reviewed literature on this topic and past agency findings. Synapse released Effect of the Draft CAFE Standard Rule on Vehicle Safety, a report prepared for Consumers Union, in October 2018.
On behalf of Northeast Energy Efficiency Partnerships (NEEP), and funded through the National Renewable Energy Laboratory, Synapse conducted an assessment across New York and New England of the region’s resources and needs as states seek to meet policy goals through strategic electrification. Specifically, Synapse surveyed stakeholders in the Northeast region--including state energy offices, local governments, utilities, and energy efficiency program administrators--to identify useful tools, resources, and databases that (a) are currently used to promote or assess impacts of strategic electrification or (b) the stakeholders would like to have to further their current work concerning electrification. The objective of this survey was to allow interested states to accelerate strategic electrification through fostering effective resource sharing, finding resource gaps, and identifying new research needs and areas. NEEP and Synapse presented a webinar on this survey to the public on September 20, 2018. Watch the webinar.

Synapse has a new EV tool! Our new EV-REDI (Electric Vehicle Regional Emissions and Demand Impacts) tool models multiple impacts of transportation electrification for specific states. With electric vehicles on the rise, there will be enormous opportunities for making transportation more sustainable and modernizing the electric grid. But to realize this potential, it will be necessary to plan ahead. More and more, states, cities, utilities, and regional authorities are seriously considering the impacts of futures in which electric vehicles play an increasingly important role in the transportation sector. EV-REDI can help meet the need to quantify the impacts of increased EV penetration on electricity sales, greenhouse gas emissions, and avoided gasoline consumption. Join us on October 18th to learn more about EV-REDI!

The electrification of transportation systems can bring substantial economic and public health benefits. Synapse’s new guidebook for consumer advocates describes how to evaluate the potential impacts of EVs on customers’ electricity rates, health, and vehicle expenditures. It also describes some of the policies that can be implemented to help ensure that transportation electrification occurs in a manner that allows all customers, particularly low-income and other vulnerable groups, to share in the benefits while not unfairly bearing the costs.
Massachusetts’ Green Communities program helps the state’s 351 cities and towns find and successfully implement clean energy solutions. To receive Green Community designation, communities must develop and implement a plan to reduce energy use by 20 percent within five years and meet additional criteria including allowing for permitting and siting of renewable energy, purchasing fuel-efficient and alternative fuel vehicles, and adopting more stringent building codes. The Massachusetts Department of Energy Resources engaged Synapse to review Green Community Annual Reports, verify whether municipalities have reached their 20 percent energy reduction goal, and develop a Progress Report for the program highlighting achievements to date. Synapse also identified strategies that are effective across towns and made recommendations to continue to advance and improve the program. Synapse developed the Green Communities Program 2016 Progress Report, available here, and provided updated analysis for 2017 and 2018.
Synapse reviewed the analysis conducted by Idaho Power Company (IPC) in support of its 2017 Integrated Resource Plan. In comments submitted on behalf of Sierra Club, Synapse identified concerns including a lack of rigorous modeling, the selection of an illegal resource plan, under-statement of future coal unit costs, and the lack of rigorous evaluation of the economic status of existing IPC coal units. Synapse recommended that IPC conduct optimization modeling in future IRPs, and fully assess the status of its Jim Bridger coal plant with respect to reasonable alternatives.

Maine’s low-income residents, like those throughout the United States, face higher energy burdens (i.e., spend proportionally more of their budgets on electricity and heating fuels) than other residents. While Maine has addressed this disparity through various measures for decades, the state and other relevant entities can act more effectively by gaining a better understanding of how and where this disparity tends to strike. With this in mind, the Maine Office of the Public Advocate commissioned a study by Synapse Energy Economics (Synapse) to shed light on the energy burdens faced by Maine’s residents. The resulting report describes Synapse’s findings on energy use in homes. We relied on various publicly available federal data sources such as the U.S. Department of Energy’s Low-Income Energy Affordability Data (LEAD) tool. We assessed differences in home energy expenditures by income bracket, by home ownership status, by type of heating fuel, and by county. The analysis reveals that Maine’s low-income households have a high energy burden: The average (mean) home energy burden for low-income households is 19 percent. On average, low-income households in the state far exceed the thresholds for the various definitions of energy poverty (generally starting with a minimum energy burden in the range of 6 to 10 percent of household income). In comparison, we find in our analysis that the average home energy burden for all Maine households is 6 percent.
Environmental Entrepreneurs retained Synapse to perform an analysis of the economic impacts of clean vehicle standards in Colorado. We assessed the likely employment and gross domestic product impacts from Colorado enacting aggressive greenhouse gas emission standards and pursuing increased electric vehicle penetration. Our summary report concluded that the pursuit of a lower-emitting vehicle fleet is likely to result in small but positive long-term macroeconomic impacts in Colorado.
Synapse provided technical support and analysis to the Massachusetts Department of Energy Resources for the development of a Comprehensive Energy Plan for the Commonwealth. The Plan is part of a broader strategy to coordinate and make consistent new and existing efforts to mitigate and reduce greenhouse gas emissions and build climate change resilience. Synapse analyzed the Commonwealth’s energy use and supply in a regional context from now until 2030 under a variety of scenarios to determine optimal policies to achieve economic competitiveness and emission goals and maintain reliability.
The final version of the Massachusetts Comprehensive Energy Plan is available at https://www.mass.gov/files/documents/2019/01/10/CEP%20Report-%20Final%2001102019.pdf.

On behalf of the World Bank, Synapse developed a transparent, user-friendly, Excel-based model that can estimate the greenhouse gas (GHG) emission reductions resulting from changes to electric-sector policies. It attempts to produce a reliable, documented estimate of GHG savings attributable to the initiative, suitable for use in international analysis and crediting of GHG reductions. This software tool is a power sector model, designed to examine effects of policies such as price changes, subsidies, and emissions taxes on the operation of an existing electric system. The current, first implementation of the model developed with stakeholder involvement from agencies in Morocco and is based on data and policy options that are specific to Morocco. The software is designed to be easily updated as new data become available. It is also readily adaptable to other countries in future implementations. Development of the tool itself, a user manual, and an internal report demonstrating the tool’s abilities were finalized in Spring 2018.
The Rhode Island Division of Public Utilities and Carriers engaged Synapse to review National Grid’s Advanced Metering Infrastructure (AMI) pilot program. Tim Woolf and Melissa Whited filed testimony in support of National Grid’s advanced metering functionality pilot, concluding that the program could provide net benefits to customers, spur company-wide AMF in Rhode Island, and provide long-lasting improvements to Rhode Island’s power sector.
Synapse is providing the Division of Public Utilities and Carriers with technical support for the National Grid rate case.

Burlington, Vermont’s municipal electric utility, Burlington Electric Department (BED) contracted with Synapse Energy Economics (Synapse) and Resource Systems Group (RSG) to develop a roadmap to provide clarity and insight into how the City could best achieve its Net Zero Energy by 2030 goal. The City’s Net Zero Energy goal is defined as reducing and eventually eliminating fossil fuel use from the heating and ground transportation sectors. Burlington currently sources 100 percent of the City’s electricity needs from renewables. Burlington’s Net Zero Energy goal is the most ambitious climate goal established by any community in the United States to date for both its rapidity and comprehensiveness.
This roadmap is a strategic analysis of the major steps or milestones needed to reach the goal with supporting data and recommended next steps for achieving the goal. The Synapse/RSG team:
- developed a 2018 baseline of energy use across all sectors;
- projected a business-as-usual trajectory through 2030;
- analyzed four pathways to net zero energy by 2030, including the magnitude and cost- effectiveness of each opportunity; and,
- detailed a host of policies and strategies with consideration for impact, cost-effectiveness and equity.
The intended audience for this roadmap is implementers of climate action goals, strategies and policies nationwide: including community and state leaders, partner organizations, utilities, and community members. The approach and supporting strategies are applicable to many communities nationwide. Policymakers, implementers, and citizens in states, regions, cities, and towns can read the roadmap here.
Synapse provided expert advice on and analysis of energy efficiency programs offered by New Jersey's Clean Energy Program for the New Jersey Division of Rate Counsel. We reviewed, analyzed, and commented on various energy efficiency-related matters, including the state-administered programs’ designs and budgets, avoided energy supply cost estimates, cost-benefit analyses, energy savings protocols updates, and fiscal year budget proposals. We also reviewed and commented on New Jersey Energy Master Plans, a three-year energy efficiency program plan called the Comprehensive Resource Analysis, and various proposals associated with the new energy efficiency program framework including program delivery structure, program design, performance incentives, and cost recovery.
Synapse prepared testimony on energy efficiency targets and incentives on behalf of the Natural Resources Defense Council in the recent Con Edison rate case. The testimony addressed the need to develop electricity and gas efficiency savings targets that are consistent with the Commission's statewide targets as well as the state's carbon emission reduction goals. It also addressed the need to provide sufficient budget to allow the utilities to provide the efficiency services necessary to meet the targets. Synapse also recommended modifications to the utility's cost-effectiveness practices to be consistent with the Commission's recent order on Benefit-Cost Analyses and to ensure the implementation of all cost-effective efficiency resources. Finally, the testimony addressed the energy efficiency earning adjustment mechanisms (i.e., performance incentive mechanisms) to ensure that Con Edison has sufficient incentive to implement effective efficiency programs, but not overlapping or unduly excessive incentives.

Consulted on issues concerning utility rate proposals that seek to establish incentives to create non-wires alternatives to transmission and distribution investments.
In 2018, Duke Energy submitted to the North Carolina Department of Environmental Quality its analysis of options for the closure of eight of its coal ash basins spread over six sites. The Southern Environmental Law Center commissioned Synapse Energy Economics, Inc. to review Duke’s Summary Reports and the Company’s analysis on trucking impacts, community and regional impacts, environmental impacts, and the estimated closure costs and schedules. Our resulting report describes how Duke's evaluation framework was designed to skew results in favor of its “Closure-in-Place” option, and in fact, to effectively ignore environmental impacts and risks. On April 1, 2019, the North Carolina Department of Environmental Quality ruled that Duke Energy must remove all ash from existing unlined landfills and move the ash to new, lined landfills.

In 2018, Prince Edward Island Energy Corporation (PEIEC) filed an application (the Application) for approval of its 2018-2021 Energy Efficiency and Conservation Plan (Plan) with the Prince Edward Island Regulatory and Appeals Commission (the Commission or IRAC). Carr, Stevenson, and MacKay hired Synapse Energy Economics, Inc. (Synapse) to assess the Plan, in particular whether the Plan is likely to satisfy legislative requirements. To this end, Synapse reviewed the Application, issued information requests, and sponsored an expert report. The report considered the reasonableness of PEIEC’s Plan in terms of scope, cost allocation, and projected savings, participation, costs, and benefits. The expert report built upon Synapse’s 2016 comprehensive, best practice report for PEI on energy efficiency program and policy requirements. Project completed May 2019.
On behalf of the Keystone Energy Efficiency Alliance (KEEA), Synapse Energy Economics (Synapse) analyzed the potential impact on energy savings, economic benefits, and net-benefits from expanding the state’s utility energy efficiency programs by increasing budgets beyond the current budget cap. Synapse examined both a Base Case scenario and an Alternative Case scenario for 2021 to 2025, the period immediately following the Phase III programs. The Alternative Case illustrates a future with more robust energy efficiency programs, possible only if state policy makers remove the budget cap before the start of the next program phase in 2021. Under the Alternative Case, we project Pennsylvania ratepayers will enjoy incremental benefits of $1.2 billion with incremental savings of about 330 MW, equivalent to a single small natural gas power plant.
