Decarbonization Plan and Model Review for Connecticut Towns
Client:
People's Action for Clean Energy
Year:
2020

The 100PercentCT Project developed by People’s Action for Clean Energy (PACE) supports the transition to a clean energy economy in Connecticut. The project’s primary function is to conduct energy analyses to help inform individual towns and the State of Connecticut about opportunities to achieve 100 percent renewable energy for the buildings and transportation sectors. PACE developed the Town Energy Analysis model—an in-house, techno-economic tool—to inventory energy use and emissions in Connecticut towns and evaluate strategies to transition to renewable energy.

Synapse performed an in-depth review of PACE’s Town Energy Analysis model to identify opportunities to improve upon and expand the model. We evaluated the modeling methods, sectors, and scope included in the energy analysis, as well as the inputs and data sources used. We compared PACE’s model alongside 10 publicly available energy and climate modeling tools to identify opportunities to align the Town Energy Analysis model with current best practices in energy and greenhouse gas accounting and in identification of mitigation opportunities.

Synapse issued a report to PACE presenting our review of the Town Energy Analysis model. First, our report summarizes the energy and climate modeling tools used to establish current energy and climate planning best practices for analytical models. Next, we validate PACE’s model and identify specific changes to improve key data, inputs, methods, and assumptions used in the model. We conclude by identifying additional modeling approaches, clean energy strategies, market segments, and energy impacts for the possible inclusion within PACE’s Town Energy Analysis model.

Economy-Wide Decarbonization for Maine
Client:
Maine Climate Council
Year:
2020

Synapse, subcontracting to Eastern Research Group, supported the Maine Climate Council in modeling economy-wide decarbonization pathways for the state that met the state’s goal of reducing emissions 45 percent by 2030 and 80 percent by 2050 below 1990 levels. Synapse analyzed the transportation, buildings, and electric power sectors using its suite of electrification and decarbonization models. Synapse used its EV-REDI and Building Decarbonization Calculator (BDC) tools to determine trajectories for the adoption of non-emitting electric vehicles (EV) and heat pumps needed to reduce emissions in line with the state’s 2030 and 2050 targets. Using these models, we also calculated the resulting electricity consumption, which we used as an input into the electric sector modeling to ensure that enough clean energy would be generated to meet the growing needs of an electrified economy. Synapse used the EnCompass model to develop a scenario in which Maine’s renewable portfolio standard increased to 100 percent by 2050. Synapse also evaluated reasonable emissions reduction trajectories in other sectors of the economy. The resulting analysis illustrated some of the tradeoffs between reducing emissions through different technological pathways. Synapse energy sector modeling informed the Maine Climate Council's recommendations published in the final report "Maine Won't Wait: A Four-year Plan for Climate Action."

Estimating the Need for New Gas Capacity in the Southeast
Client:
Southern Environmental Law Center
Year:
2020

The FERC approved the Atlantic Coast Pipeline (ACP) in 2017. Project owners Duke and Dominion filed a certificate for a construction extension with FERC on June 16, 2020. On behalf of the Southern Environmental Law Center, Synapse assessed the projected demand for new gas used for electric generation, estimating the “maximum demand for new gas” on a peak winter day in Dominion’s and Duke’s service territories. We examined public IRPs, new policies in Virginia and North Carolina that will lower CO2 emissions in the electric sector, and public documents related to the utilities’ internal emission reduction goals. We used that data to build spreadsheet models to assess maximum future gas demand on a winter peak day. Our analysis demonstrates that the need for new gas-fired generating resources originally anticipated by Duke and Dominion has not and will not materialize, thus negating the utilities’ claimed need for the ACP.

Expert Testimony in Virginia Regarding Alternatives to Dominion’s 2020 IRP
Client:
Sierra Club
Year:
2020

Synapse assisted the Sierra Club with evaluating Dominion’s 2020 Virginia IRP and modeling alternative scenarios demonstrating the cost effectiveness of clean energy generation and coal retirements. Synapse modeled an optimized Virginia Clean Economy Act (VCEA) compliant scenario in EnCompass that resulted in lower emissions and lower costs than Dominion’s preferred plan. Rachel Wilson sponsored testimony describing how the Synapse scenario eliminated unnecessary gas capacity additions that Dominion fixed in its modeling, and showed that accelerating retirements of certain coal units by increasing solar generation capacity would save ratepayers billions of dollars. In addition, Synapse reviewed Dominion’s position regarding the PJM Minimum Offer Price Rule (MOPR) and the Fixed Resource Requirement (FRR) alternative to participating in the PJM capacity market under the MOPR. Jason Frost sponsored testimony describing how the MOPR will increase the costs of meeting state clean energy goals and require Dominion to retain unnecessary legacy fossil fuel powered generation by not counting renewable capacity. Mr. Frost’s testimony also discusses how the FRR presents a way to avoid the negative impacts of the MOPR, and can reduce consumer costs by avoiding the need to pay for legacy fossil fuel capacity that is no longer needed.

Identifying Gaps Between Utility Decarbonization Targets and Actions
Client:
Climate Majority Project
Year:
2020

Electricity generation from Duke Energy, Dominion Energy, and Southern Company utilities collectively represent 12.4 percent of U.S. power sector CO2 emissions – equivalent to 4.2 percent of total U.S. CO2 emissions. While all three utilities have announced plans to decarbonize their electricity generation by 2050 in order to meet climate targets, a deeper look into their generation portfolios and plans reveals that all three utilities are on track to fall short of their emissions reduction commitments.

On behalf of the Climate Majority Project, Synapse investigated the companies’ current plans for fleet decarbonization. We made the following recommendations to help ensure a path to reach climate targets by 2050: (1) develop science-based CO2 trajectories upon which all future plans and actions should be rooted; (2) conduct robust retirement and replacement analysis to determine the least cost path to retire each company’s existing fossil fleet and replace it with alternative zero-carbon portfolios; (3) invest in renewables and demand-side resources to meet future resource needs; (4) invest in grid-modernization solutions in tandem with retirement of existing resources and development of renewables; and finally (5) evaluate and plan for changing system needs, including load growth driven by electrification instead of traditional steady demand.

Job Impacts of Investing in Public Infrastructure in Massachusetts
Client:
Labor Network for Sustainability
Year:
2020, 2019

Synapse worked on behalf of Labor Network for Sustainability to analyze the economic benefits of improving energy, water, and transportation infrastructure in Massachusetts through increased state, municipal, and public investment. First, we identified spending gaps between existing investment plans for these three sectors and the level of investment needed to bring the sectors to a state of good repair. We used infrastructure needs reports, gap analysis studies, and state policy goals to identify the spending gaps. Next, we calculated the employment impacts of improving this infrastructure through increased investment between 2020 and 2030. We used IMPLAN, an industry-standard job impact model, to convert annual spending levels into annual job creation. We produced a final report summarizing the results for all three sectors as well as a selected set of city-specific case studies.

Rate and Bill Impacts of National Grid Rhode Island Natural Gas Programs
Client:
National Grid
Year:
2020

National Grid commissioned Synapse to develop a Microsoft Excel-based analytical model to assess the long-term rate and bill impacts of its Rhode Island energy efficiency natural gas programs. The model was designed to analyze annual and long-term rate and bill impacts from natural gas energy efficiency programs implemented over a course of three years. Synapse designed the model to analyze rate and bill impacts from natural gas energy efficiency programs in Rhode Island for four customer types: residential, income-eligible, small commercial, and large commercial and industrial (large C&I) and for each program contained within those categories. The model was designed for National Grid’s 2021–2023 Three-Year Energy Efficiency Program Plan and its 2021 Annual Program Plan, but it can be updated for subsequent prospective and retrospective analyses in assessing how the Plans meet the requirements for energy efficiency in Rhode Island.

Solar Siting Opportunities for Rhode Island
Client:
Rhode Island Office of Energy Resources
Year:
2020

On behalf of the Rhode Island Office of Energy Resources (OER), Synapse conducted a geospatial analysis to determine an estimate of the likely solar potential available within a number of solar siting categories. Synapse examined and quantified solar potential for the following six siting categories:

-Rooftop solar (including rooftops of residential single family, residential multifamily, commercial, industrial, municipal, and other building types)

-Ground-mounted solar in the following four categories: (1) Landfills, (2) gravel pits, (3) brownfields, and (4) commercial and industrial developed and undeveloped lots

-Parking lot / carport solar

We used geospatial analysis to examine the following types of potentials for each category of solar:

-Total Potential, an estimate of the solar potential for the entire area under consideration, with no exceptions.

-Technical Potential, an estimate of the potential excluding areas not suitable for solar development. These challenges may reduce technical potential, relative to total potential.

For residential rooftop solar, we also analyzed:

-Economic Potential, an estimate of the solar potential that is likely to be installed, given the current cost of the technology, the current financial incentives available, and the household economics specific to a municipality. This potential category was analyzed for residential rooftop solar only.

In addition, for each category of solar, we compiled estimates of these MW potentials translated into gigawatt-hour (GWh) generation potential, solar costs (based on costs available as of late 2019 / early 2020), avoided greenhouse gas emissions, and possible impacts on distribution system hosting capacity.

On August 18th, 2020, Synapse staff presented the results of this analysis in an online webinar presentation, which can be found here. A list of webinar attendees can be found here.

Southwestern Public Service Company (Xcel) Rate Case Focusing on the Tolk and Harrington Coal Plants
Client:
Sierra Club
Year:
2020, 2019

Synapse provided expert witness testimony and analysis to Sierra Club for Southwestern Public Service Company's (SPS) 2019 rate case in the states of New Mexico and Texas. The case focused on the retirement date for the Tolk Plant, which the Company was requesting be moved up based on a water shortage in the region that would limit the ability for SPS to continue economically operating the plant year-round through its current retirement date. Synapse’s testimony and analysis focused on both the recent historical and future projected economic performance of Tolk under the Company’s proposed seasonal operations plan for the plant moving forward. We also evaluated the Harrington Coal-fired Power Plant. We found that both plants are likely to lose money going forward relative to alternatives and the market, and therefore SPS should develop a plan to retire both plants. SPS has been required to update its analysis on the future operation of the Tolk Power Station.

Duke 2018 IRP: Modeling an Alternative Resource Portfolio
Client:
North Carolina Sustainable Energy Association
Year:
2019, 2018

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.

Electrify Everything meets Polar Vortex 2019: What can we learn?
Client:
Year:
2019

The late January 2019 Polar Vortex weather event brought extreme temperatures to the upper Midwest through New England – the same stretch of the country where the most fossil fuels are used to heat buildings. As it becomes clear that a decarbonized electric grid is possible, “#ElectrifyEverything” has become a rallying cry for the path to transportation and building decarbonization. In this webinar, we explore the hypothetical: What if all the buildings from the Dakotas, to the Ohio River Valley, through Maine were heated with cold climate heat pumps instead? We estimate the impact on hourly peak electric loads, and we use this to tee up and discuss questions about what a cost-effective plan to decarbonize these buildings would need to address.

Net Zero Energy Roadmap for Burlington
Client:
Burlington Electric Department
Year:
2019, 2018

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.

Non-Wires Alternatives to Building a New Substation in Washington, D.C. – Key Takeaways for Other Jurisdictions
Client:
DC Department of Energy and Environment
Year:
2019

Washington D.C. is experiencing rapid development of new residential and office buildings in and around the Mt. Vernon Triangle area. In response, the local utility has proposed building a new substation to serve the expected load growth at a cost of approximately $150 million. The utility reviewed and incorporated some energy efficiency and other distributed energy resources (DER) in its load forecast, but concluded that such non-wires solutions (NWAs) do not provide enough capacity to resolve the expected distribution constraints. However, Synapse Energy Economics’ analysis revealed that the utility’s plan did not adequately account for the potential impacts of cost-effective targeted DER solutions or future building codes.

Synapse conducted a comprehensive assessment of the utility’s load forecast and the feasibility of NWAs. We quantified cost-effective NWAs sufficient for deferring the need for the substation. This presentation highlights the key issues, assumptions, methodologies, and results from our analysis. Further, we present how our findings can be applied to other regions facing similar situations. Specifically, this presentation covers: (a) peak load forecasting methodologies; (b) peak load assumptions for existing buildings and new construction; (c) solar PV projections; and (d) achievable energy efficiency and demand response potential for the Mt. Vernon area. Synapse used building load data, existing end-use level potential studies, and program performance from leading programs to estimate energy efficiency and demand response potential. The presenter will also highlight studies and leading programs Synapse referenced to develop key assumptions on energy savings, costs, and participation rates.

Powering Ohio
Client:
Environmental Defense Fund
Year:
2019, 2018, 2017

With support from Environmental Defense Fund, Synapse convened a stakeholder advisory council and provided analysis to produce a vision of Ohio’s clean energy economic opportunities. The group—comprised of business leaders, manufacturers, academics, labor representatives, non-profits, and others—produced a shared vision report of how Ohio could create new jobs and economic growth by modernizing its energy economy. Essentially a business case for clean energy growth and innovation, the vision identifies multi-billion dollar opportunities related to attracting leading corporations, transforming transportation, building and deploying clean electricity and energy efficiency, and modernizing the grid, to demonstrate why Ohio is well-positioned to lead if it takes action. The vision also highlights the risks of failing to create conditions that allow Ohio businesses to compete on the national and global levels. Synapse and the advisory group followed the release of the vision report with further stakeholder engagement and analysis, leading to a second report focused on actions that the public and private sectors can take to advance the clean energy economy in Ohio.

San Juan Replacement Study
Client:
Sierra Club
Year:
2019

On behalf of the Sierra Club, Synapse modeled the electric system in New Mexico using the EnCompass model in both capacity expansion and production cost modes. Synapse comprehensively modeled zero-emission alternatives to a new utility-proposed gas-fired generation option intended to replace the retiring San Juan Generating Station units in New Mexico in 2023. The modeling accounts for the interconnectedness of the electric power grid in the Desert Southwest region, including detailed representation of generation units in Arizona and New Mexico (and portions of Texas and California), and aggregated treatment for resources in the rest of the West.

Synapse finds that a combination of utility-scale and small-scale solar PV, utility-scale battery storage, incremental wind resource procurements, and increased deployment of demand response will provide Public Service of New Mexico with a less-expensive, and lower-emitting alternative than its proposed gas-fired generation, while meeting all reliability requirements. Utility-scale battery storage in particular is a key part of the resource portfolio. Storage resources can be deployed incrementally to provide a firm capacity resource that can be directly controlled by the utility, charged by any grid resources, and provide valuable regulation up and down and ancillary services.

Year:
2018

In order to fulfill its ambitious greenhouse gas emission goals, California will need to decarbonize its buildings, which are responsible for 25 percent of the state's climate emissions. California's legislature recently passed a law requiring that the state have 100 percent carbon-free electricity by 2045.In October, Synapse released a report (prepared on behalf of NRDC) examining the technology available for clean and efficient electric heating, the customer benefits of decarbonizing buildings, the electric grid impacts of doing so, and policy recommendations for getting there. The report particularly illuminates the importance of electric rate design to the customer economics and grid impacts of building decarbonization. California has been leading on developing electric vehicle rate designs and now has the opportunity to develop rates that work for low-emission buildings as well. 

On Thursday, November 15, 2018, Synapse hosted a Third Thursday webinar discussion of these issues with Asa S. Hopkins, PhD, lead author of Decarbonization of Heating Energy Use in California Buildings, and Synapse Principal Associate Melissa Whited.

Clean Energy for Los Angeles
Client:
Food & Water Watch
Year:
2018, 2017, 2016

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.

Cleaner Cars and Job Creation
Client:
Union of Concerned Scientists
Year:
2018

Synapse analyzed the macroeconomic impacts of federal fuel economy standards and state zero-emission vehicle standards on the U.S. economy. Our team compared the impacts of vehicle standards set for 2017-2025 to the impacts of keeping standards at 2016 levels. Our analysis indicated that federal and state vehicle standards will result in positive employment impacts and GDP growth in both the short term and long term. Synapse released Cleaner Cars and Job Creation, a report prepared for Union of Concerned Scientists, Natural Resources Defense Council, and American Council for an Energy-Efficient Economy, in March 2018.

In a follow-up report entitled Giving Back Half the Gains, we extended our Cleaner Cars Analysis to explore the macroeconomic impacts of the proposed rollback of the standards (henceforth called the flat-lined standards), relative to the same 2016-technology baseline. We then compared the employment and GDP impacts of the proposed flat-lined standards with the employment and GDP impacts of the existing clean vehicle standards. We found that the proposed flat-lined standards will generate 60,000 fewer job-years in 2025 and over 120,000 fewer job-years in 2035 than the existing clean vehicle standards. Furthermore, the proposed flat-lined standards will reduce GDP by $8 billion in both 2025 and 2035 when compared to the existing clean vehicle standards. We concluded that the proposed flat-lined standards are expected to reduce the positive impacts on the U.S. economy that would be generated under the existing clean vehicle standards compared to the 2016-technology baseline.

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.

Massachusetts Comprehensive Energy Plan
Client:
Massachusetts Department of Energy Resources
Year:
2018

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.

Net Zero Energy Roadmap for Burlington
Client:
Burlington Electric Department
Year:
2019, 2018

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.

Powering Ohio
Client:
Environmental Defense Fund
Year:
2019, 2018, 2017

With support from Environmental Defense Fund, Synapse convened a stakeholder advisory council and provided analysis to produce a vision of Ohio’s clean energy economic opportunities. The group—comprised of business leaders, manufacturers, academics, labor representatives, non-profits, and others—produced a shared vision report of how Ohio could create new jobs and economic growth by modernizing its energy economy. Essentially a business case for clean energy growth and innovation, the vision identifies multi-billion dollar opportunities related to attracting leading corporations, transforming transportation, building and deploying clean electricity and energy efficiency, and modernizing the grid, to demonstrate why Ohio is well-positioned to lead if it takes action. The vision also highlights the risks of failing to create conditions that allow Ohio businesses to compete on the national and global levels. Synapse and the advisory group followed the release of the vision report with further stakeholder engagement and analysis, leading to a second report focused on actions that the public and private sectors can take to advance the clean energy economy in Ohio. For more information, see www.poweringohio.org.
