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 worked with New Hampshire's Benefit/Cost Working Group to develop an energy efficiency cost-effectiveness framework that is intended to fully reflect state energy policy goals. Synapse and the working group applied the seven steps framework of the National Standard Practice Manual to develop the new framework for New Hampshire. Synapse recommends New Hampshire utilities adopt the Granite State Test as the primary cost-effectiveness test for energy efficiency resources, and review the results of a secondary Granite State Test as well as the Utility Cost Test when assessing program cost-effectiveness.

On behalf of the Environmental Defense Fund, Synapse conducted a benefit-cost analysis of a regulation to curb methane emissions from the oil and gas industry in New Mexico. The analysis evaluated the Gold Standard set of emissions regulations, comparing implementation costs to several types of benefits to the state of New Mexico: sales from newly captured gas, avoided costs related to human health impacts, and avoided nonattainment costs of reduced GHG emissions. Additionally, the report evaluated the global societal benefit of reducing methane emissions into the atmosphere.

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.

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.

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 Sierra Club, Synapse analyzed the impacts of incremental policies on vehicle electrification and GHG reductions. We used MA3T, a consumer adoption model developed by Oak Ridge National Laboratory, and EV-REDI, a stock-flow impacts model developed by Synapse, to understand the impacts of EV rebates, pollution fees, and investments in public charging infrastructure on New York's EV sales, EVs on the road, CO2 emissions, and other metrics. We found that GHG reductions of 55% by 2035 from motor vehicles are achievable and will put New York on track to achieve long-term climate commitments.

A decade ago, urban-transportation activist (and one-time chronicler of nuclear power cost escalation) Charles Komanoff began programming “the Balanced Transportation Analyzer” — an Excel spreadsheet that synthesizes the volumes, costs, and interactivities among auto traffic, subways and buses, trucks and taxis in New York City. In fall 2017, the analytics team advising New York Governor Andrew Cuomo selected the “BTA” as its primary tool to score methods for designing a congestion-pricing plan. The report released in January 2018 by the governor’s Fix NYC task force has spurred vigorous debate, with transportation-reform advocates rallying around congestion pricing as the key policy measure to relieve chronic Manhattan traffic congestion and provide new funding to repair and revitalize the city’s ailing subways.

On February 15, 2018, Charlie joined Synapse for a webinar on congestion pricing and the BTA. His talk covered the intricacies of traffic modeling, his calculations of net benefits from congestion pricing, the implications of the New York congestion-pricing debate for urban transportation reform, and other potential applications of externality pricing (e.g., carbon taxes) in the United States.

Bruce Biewald, CEO/Founder of Synapse Energy Economics, moderated the discussion. This webinar is part of Synapse’s Third Thursday webinar series.

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 prepared a Technical Brief that provides an overview of benefit-cost analysis techniques for reviewing utility proposals for grid modernization investments. The Brief is written for regulators, consumer advocates, and other stakeholders who seek to determine whether grid modernization proposals are in the public interest; especially proposals for utility-facing technologies that help advance reliability, resilience, advanced metering, and the integration of distributed energy resources. The Technical Brief addresses some of the most challenging aspects of benefit-cost analysis for grid modernization, such as determining the appropriate cost-effectiveness test to use, accounting for interactive effects between grid modernization components, and accounting for qualitative benefits. Tim Woolf presented the material in a training course for consumer advocates at the meeting of National Association of Utility Consumer Advocates in November 2018. He also presented the material at the Mid-Atlantic Distribution Systems and Planning Training with the NARUC-NASEO Task Force on Comprehensive Electricity Planning on March 8, 2019.

Electric vehicles (EVs) have the potential to provide substantial benefits to society by reducing emissions while lowering both transportation fuel costs and electricity rates. Effective EV rate design is critical for ensuring that these benefits are realized. Through rate design, electric utilities are in a unique position to ensure that EVs charge in a manner that minimizes costs to the grid, while providing customers with fuel savings relative to gasoline, which helps to drive EV adoption.

On behalf of the Natural Resources Defense Council, Synapse evaluated EV rate design at both the state and national levels. In June 2018, Synapse released Driving Transportation Electrification Forward in New York, a report examining New York utilities’ electric vehicle rate design proposals. NRDC filed this report along with comments in Docket 18-E-0206. The Synapse team then released a similar report for Pennsylvania. A national report currently in the works will provide utilities, regulators, and other stakeholders with an overview of key issues and best practices from a national perspective.

Tampa Electric Company (TECO) filed an application to construct a new 1090 MW gas-fired power plant at a cost of $895 million. This so called “modernization” project sought to repower an existing steam turbine at the site of the coal- and gas-fired power plant at the Big Bend Power Station in Tampa, Florida. Synapse provided analysis and expert testimony on behalf of the Sierra Club to evaluate the need for, and impact of, the proposed plant.

Synapse found that TECO's application did not demonstrate a need for the electricity generated by this new gas plant, and made numerous dubious claims about the project’s environmental and economic benefits. Witness Bruce Biewald submitted testimony on the climate damages that will result from the construction of the gas plant. Witness Devi Glick submitted testimony assessing the electrical energy needs of TECO’s customers, and identifying ways to meet those needs through better system planning and cleaner, lower cost alternative resources.

In 2018 the U.S. Environmental Protection Agency (EPA) and National Highway Traffic Safety Administration (NHTSA) issued a proposal to roll back existing Corporate Average Fuel Economy (CAFE) and tailpipe greenhouse gas (GHG) emission standards for light-duty vehicles to model year 2020 levels. Under the existing CAFE and GHG standards, requirements grow increasingly stringent through model year 2025. On behalf of the California Department of Justice, Synapse evaluated the macroeconomic impacts of the proposed rollback. We found that (1) the agencies' own analysis indicated that the proposed rollback would result in job losses; (2) the proposed rollback would result in reduced vehicle sales; (3) when accounting for broader economic impacts, the proposed rollback would result in greater job losses than those predicted under the agencies' analysis; and (4) the proposed rollback would negatively impact U.S. gross domestic product.

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.
