Sierra Club retained Synapse to conduct an updated economic analysis of the J.K. Spruce coal plant, located near San Antonio, Texas. Synapse evaluated the recent economic performance of the plant, the likely performance of the plant over the next two decades, and the availability of cost-effective renewable alternatives to Spruce. Synapse found that (1) the Spruce plant likely lost more than $100 million relative to the market between 2013 and 2018; (2) Spruce is likely to continue to lose money relative to the market in the near term; (3) Spruce will only become profitable relative to the market over the long term if a series of favorable conditions hold; (4) CPS would likely save money by replacing the Spruce plant with renewable resources, even under market conditions favorable to the Spruce units; (5) replacing Spruce with renewables would reduce emissions and associated regulatory risks in addition to likely reducing costs; (6) retiring uneconomic coal units would be unlikely to harm CPS's credit rating; and (7) the current planned Spruce retirement dates are not based in a sufficiently robust and transparent planning process. We concluded that CPS should promptly engage in a thorough, public planning process to evaluate the potential near-term retirement of the Spruce units.

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.

On behalf of Sierra Club, Synapse developed a least-cost resource portfolio to inform future plans for the Santee Cooper public utility in South Carolina. The resulting report explores a variety of energy mixes for the state-owned utility, and demonstrates that Santee Cooper’s continued reliance on coal or building large fracked-gas plants would be the costliest options. The least-cost option entails a combination of renewable energy resources and energy efficiency.

On behalf of Maine Renewable Energy Association and other Maine stakeholders, Synapse partnered with Sustainable Energy Advantage to assess the impacts of expanding Maine’s Class I renewable portfolio standard (RPS) to reach 50 percent by 2030. This analysis found that expanding the RPS would: Create 170 jobs per year between 2020 and 2030; Improve public health by curbing air pollution, avoiding $500,000 per year in public health damages between 2020 and 2030; Add 700 MW of new, in-state renewable energy projects; Result in minimal impact to Maine’s ratepayers, with only slight increases in residential bills of $1.16 to $1.76 per month between 2020 and 2030; and Reduce Maine’s reliance on fossil fuels by 5% and curb greenhouse-gas emissions from the electric sector attributable to Maine by 55%.

Burlington, Vermont’s municipal electric utility, Burlington Electric Department (BED) contracted Synapse and Resource Systems Group (RSG) to develop a roadmap on how the city could best achieve its Net Zero Energy by 2030 goal. The City’s goal is defined as reducing and eventually eliminating fossil fuel use from its heating and ground transportation sectors. 

This roadmap is a strategic analysis of the major steps or milestones needed to reach the City's Net Zero by 2030 goal with supporting data and recommendations for next steps. In order to develop this roadmap, 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
  •   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. The roadmap is publically available and can be viewed here.  

In early 2021, Synapse was contracted by BED to update GHG emissions and other decarbonization metrics for Burlington in order to compare actual progress in 2019 and 2020 to the projections modeled in the Net Zero Energy Roadmap. This analysis showed that Burlington's emissions have fallen 15 percent since 2018, in line with a Net Zero trajectory. The COVID-19 pandemic contributed significantly to emissions reductions in 2020, particularly by reducing the number of miles driven in private vehicles. Burlington now has the opportunity to double down on decarbonization measures, including the electrification of transportation and heating, to mitigate any post-pandemic emissions rebound.

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.

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.

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.

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.

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.

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.

This report investigates various risk factors that could have an adverse effect on TVA’s costs and, thus, rates in the next 10 years. The purpose of this report is not to forecast future rates, as the probabilities of many uncertainties are unknown, but rather to examine the extent to which some factors could increase costs and rates above expectations. Synapse has reviewed extensive historical materials as well as forward‐looking public materials and statements about expectations and plans in order to quantify the potential impact from several cost categories. Synapse analyzed the five risk factors and roughly quantified the potential rate increases over the next 10 years. We also developed an overall estimate of the potential combined impacts for 2026 and 2031 for MLGW that represent a reasonable range of possible futures, taking into account the potential impacts for the five risk factors over the next 10 years. Our analysis concludes that there are potential rate increase risks for MLGW customers ranging from 9 percent to 34 percent per year by 2031, for a total increase of approximately $90 million to about $340 million by 2031.

On behalf of the Office of the People's Counsel for the District of Columbia, Synapse performed a Ward-level analysis of three future solar scenarios for the 2019-2041 timeframe. Using geospatial and economic analysis, Synapse also calculated the likely mix of private and community solar for the District, as well as the likely mix of rooftop, parking lot, and ground-mount solar through the study period. Based on the scenarios developed, Synapse recommended courses of action to help the District meet its ambitious solar carve-out goal (10% in-District solar by 2041). Finally, Synapse conducted a rate impact assessment of each solar scenario to determine which has the best impact on ratepayers in the District. Synapse recommended the District government closely monitor progress of the solar installations relative to the carve-out, as benefits are greatest if compliance is achieved early in the study period.
