On behalf of the Sierra Club, Erin Camp, PhD wrote expert witness testimony evaluating Dominion Energy’s electric vehicle (EV) Smart Charging Infrastructure Pilot Program (“Pilot Program”), focusing on the light-duty EV stock growth projection for Dominion’s service territory. The EV stock growth projection, which was used to calculate the number of EV charging stations eligible for rebates in the Pilot Program, underestimated the likely adoption of light-duty EVs in the Company’s service territory. Dr. Camp’s analysis found that, by 2030, the number of registered EVs in the Dominion’s service territory is likely to be double what was predicted by the utility. Her testimony encouraged the utility to recalculate the forecasted EV market and to update the estimated number of required EV charging stations. Dr. Camp also explained that encouraging EV adoption with a well-designed utility program can put downward pressure on rates and benefit all consumers in Dominion’s service territory. Further, a well-designed program will also ensure that the benefits of transportation electrification are equitably distributed to all customers, including low- and moderate-income customers, by improving access to clean, electric transportation options in the form of electric transit (i.e., buses) and charging stations to support EV charging at multi-family buildings.

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.

Synapse is assisting Energy Outreach Colorado in responding to Public Service Colorado’s time-of-use (TOU) rate implementation proposal. TOU rates have the potential to provide customers with greater control over their bills and reduce system costs. However, to be successful, TOU rates must be implemented thoughtfully and with sufficient customer education, protections, and choice. Synapse’s testimony focuses on best practices for implementing TOU rates and particularly for ensuring that low-income customers are adequately protected and are not subject to rates that would be disproportionately burdensome.

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.

Synapse provided expert testimony and analysis to support Sierra Club in reviewing Wisconsin Power and Light (WPL) and Madison Gas and Electric’s (MGE) Fuel Cost Plans for 2021. Synapse’s testimonies focused on reviewing the operational practices used by MGE and WPL at the companies' coal-fired power plants at the Columbia Energy Center and Elm Road Generating Station. We also evaluated the plants' recent economic performance and discussed the risks these uneconomic unit commitment practices pose to MGE and WPL’s ratepayers. We found that the companies have not historically used price-based unit commitment process either in practice or in developing their annual fuel cost plans and that the current fuel planning process anticipates and enables uneconomic unit commitment by the companies.

We recommended that the companies be required to model their units operating economically for planning purposes, and to refresh their current plants to reflect this assumption. Further, we recommended that the companies be required to economically commit their units into the market, or otherwise to document their unit commitment decision-making process. Finally, we recommended that the Public Service Commission of Wisconsin make clear to utilities that their unit commitment practices will be subject to prudence reviews in the future reconciliation dockets.

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.

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 the Sierra Club and Natural Resources Defense Council, Synapse provided technical support and expert witness testimony in California docket A19-11-019. Synapse conducted a bill impacts analysis for customers in three different climate zones who might electrify their home on Pacific Gas & Electric's proposed E-ELEC time-of-use rate. Dr. Erin Camp authored expert witness testimony, demonstrating that electrifying on the proposed E-ELEC rate is not likely to be economical for customers who live in multi-family buildings, especially those customers who are low-income. In her testimony, Dr. Camp advocated for a separate, additional electrification time-of-use rate for all low-income customers in PG&E's service territory to alleviate the barrier to electrifying for this vulnerable customer group. Her analysis led to a successful E-ELEC settlement rate.

The Massachusetts Department of Energy Resources retained Synapse and subcontractor DNV GL to produce a comprehensive assessment of mobile energy storage systems and their use in emergency relief operations. The study explored the landscape of available mobile energy storage systems, which are roughly divided into towable units and self-mobile systems in the forms of various electric vehicle (EV) platforms. Mobile energy storage systems may be uniquely capable of enhancing energy resilience in response to severe weather events and associated outage conditions. The study found that mobile energy storage systems can be self-mobile electric vehicles (light-duty vehicles, vans, or buses) or towable (towable or transportable via semi-trailer truck). This study provided a comprehensive assessment of mobile energy storage systems, their use in emergency relief operations, and their use on typical (non-outage) days. Specifically, this report addressed four fundamental questions: state-of-the-art, usage on typical days, opportunities and challenges to deploy in response to outages, and potential advantages over stationary battery energy storage systems.

The final report, Mobile Energy Storage Study: Emergency Response and Demand Reduction, is available on the Department of Energy Resources website.

Using hourly, publicly available data, Synapse examined the impact of solar on energy benefits. From 2014-2019, behind-the-meter solar created $1.1 billion in energy benefits in the six New England states. These include savings resulting from purchasing less electricity, as well as savings due to lower overall electricity prices. We estimate that solar contributed to $87 million in public health benefits, and reduced CO2 emissions by 4.6 million metric tons, equivalent to taking one million cars off of the road.

Of all U.S. states, Florida will feel the largest direct impacts from climate change. Given the City of Orlando’s vulnerability to climate impacts, Mayor Dyer and Orlando City Commissioners commitment to 100 percent renewable energy by 2050 was a critical move. Yet Orlando’s electric utility, the Orlando Utilities Commission, still relies almost entirely on fossil fuels to supply the City’s electricity. The City is currently conducting an integrated resource planning exercise to determine the future of its electricity system; this study focuses strongly on fossil resources and includes an evaluation of whether to keep the Stanton Energy Center online, convert the units to gas, or retire the plant. In response to the utility’s IRP exercise, Synapse conducted a study on behalf of the First 50 Coalition to evaluate an alternative renewable and clean energy portfolio that can provide the City with the energy and capacity it needs at a lower cost and lesser environmental impact than the fossil heavy system that the City’s IRP will propose.

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.

Synapse is providing expert testimony and analysis to support Sierra Club in Duke Energy Indiana’s Fuel Adjustment Cost (FAC) dockets for the period of September 2019 through May 2020.

Synapse is evaluating the unit commitment and dispatch practices for Duke’s four coal plants at Edwardsport, Cayuga, Gibson, and Gallagher as part of the Company’s regular Fuel Adjustment Cost Adjustment (FAC) dockets. We find that Duke has been uneconomically committing most of its units a majority of the time throughout this entire time period. These commitment and dispatch practices were further exacerbated by the Company’s implementation of a fuel price decrement in FAC 125 (March – May 2020) to address the Company’s coal oversupply.

We find that as a result of the Company’s uneconomic commitment and dispatch practices, Duke has accumulated net revenue losses (based on just variable and fuel costs) at most or all of its units during at least one (and in most cases all) of the FAC 123, FAC 124, and FAC 125 periods between September 2019 and May 2020. As a result of our work in FAC 123, the Indiana Utility Regulatory Commission agreed to open a subdocket to examine the issue of unit commitment more closely. Synapse has provided expert support and testimony in all three FAC periods as well as the subdocket.

Apogee Climate and Energy Transitions (Apogee) engaged Synapse to review the publicly available documents associated with the Kentucky Municipal Energy Agency's (KYMEA) 2020 Integrated Resource Plan. Synapse provided Apogee with a memo detailing its concerns with KYMEA's IRP and providing short, medium, and long-term recommendations. Dr. Thomas Vitolo summarized these findings and recommendations in a public comment at a KYMEA Board meeting on September 24, 2020.

Dr. Vitolo advised the KYMEA Board against further investments in fossil-fuel power plants or long-term contracts. He explained that the KYMEA has no need to invest in new power supplies until 2027 at the earliest and is fortunate that a 100-Megawatt coal contract is expiring in 2022, freeing KYMEA of the plant’s costs and risks. Dr. Vitolo also noted that KYMEA had an immediate opportunity to reduce its commitment to a natural gas peaking power contract with Paducah Power Systems, from 90 Megawatts to 30 Megawatts. He advised the KYMEA to actively pursue re-negotiating each of their existing power contracts in light of the much lower prices available in MISO. Lastly, Dr. Vitolo observed that for the medium and long-term perspectives, in-state solar power contracts are likely to provide low-cost, low-risk, and reliable energy to their customers.

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.

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.
