Synapse has been retained to evaluate National Grid’s Massachusetts rate design proposals, filed as part of its 2016 rate case. In its application, the Company proposed to impose tiered customer charges on residential and small commercial customers intended to act as a proxy for a demand charge. Synapse submitted testimony that demonstrated why the Company’s proposal not only failed to improve customer equity, but would also be unnecessarily complex, difficult for customers to respond to, and would undermine price signals for energy efficiency and distributed energy resources. Specifically, Synapse conducted statistical analysis to show that the Company’s proposed proxy for a demand charge was no better of an indicator of customer demand than an energy charge, and also failed to account for customer demand diversity and the coincidence with system peak demands.

Rebuttal Testimony of Tim Woolf and Melissa Whited Regarding National Grid Rate Design Proposal
Synapse is reviewing performance incentive mechanisms for HELCO and HECO on behalf of the Division of Consumer Advocacy.
Indiana Michigan Company (I&M) submitted an application to the Indiana Utility Regulatory Commission seeking a certificate of public convenience and necessity to install Selective Catalytic Reduction at Rockport Power Plant Unit 2 near Rockport, Indiana. Synapse assessed the analysis conducted by American Electric Power Generating Services on behalf of I&M in support of the application. Specifically, Synapse examined if the installation of the controls would be in the interest of I&M’s ratepayers and if the proposal was consistent with regulatory requirements. On behalf of Citizens Action Coalition of Indiana, Sierra Club, and Valley Watch, Dr. Jeremy Fisher submitted testimony to the Commission recommending that the Commission deny the CPCN on the basis that the Company’s analysis is outdated and Rockport 2 is not a reasonable long-term resource.

As new, more stringent federal environmental regulations come into effect, the fleet of U.S. coal-fired power plants is becoming increasingly less economic in comparison to the alternative of electricity market purchases. Numerous industry groups, environmental advocates, and government agencies have published estimates of the U.S. coal capacity at risk of retirement. However, all of these estimates have been conservative in that they have excluded the costs of installing and operating some of the controls expected to be required for compliance with environmental regulations, and/or they have assumed a long-run carbon-emission price of zero. This study explores a more comprehensive set of assumptions, using Synapse's Coal Asset Valuation Tool (CAVT). CAVT (now on version 6.0) is a spreadsheet-based database and model that forecasts the costs for individual coal units to comply with environmental regulations, and compares these forecasts to electricity market prices. It includes cost estimates for all expected environmental retrofits along with carbon prices.

Challenges for Electric System Planning
2016 NECPUC Symposium Presentation
On June 10, 2014, the Maine Public Utilities Commission issued a Notice of Inquiry (NOI) into the design and implementation of a methodology to determine the value of distributed solar energy in the state of Maine. To inform the inquiry, which served as the first step in designing a study mandated by legislation to support solar energy development in Maine (P.L. 2013 CH. 562), the Commission asked interested parties to respond to questions detailed in the NOI. Synapse assisted the Maine Office of the Public Advocate (OPA) in responding to the inquiry, and later in developing comments on the subsequent draft value of solar methodology issued by the PUC on October 30, 2014.
The OPA’s comments on the draft methodology include recommendations on assumptions about fuel price escalation and heat rate, and suggested modifications to the technical and economic analysis that would more closely align the methodology with best practices.

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.
The Proposed Plant at Big Bend: A Review of Climate Impacts
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.
Synapse's Ben Havumaki and Tim Woolf lead an afternoon conversation about grid modernization that both addresses broad themes and zooms into the nitty gritty. Topics include:
- Overview of key concepts in grid mod
- Benefit-cost analysis, including how to select an appropriate cost test for grid mod projects
- Challenges in quantifying costs and benefits
- Customer equity
- Best practices
- Case studies of recent utility-facing grid modernization plans
CEP Comments on Future of Value Stack
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. Project ongoing.
As a continuation of previous work, Synapse provided NS UARB with consulting services on energy efficiency issues. Specific areas where Synapse provided technical support and analysis included: rate and bill impacts, non-energy benefits, methodology to determine program incentives, and benefits of location-specific efficiency targeting.
Comments on EfficiencyOne’sJanuary 21, 2019 Locational DSM Pilot –DSMAG Update
Synapse reviewed the Energy Efficiency Plan filed by the Prince Edward Island Energy Corporation for its conformance with the provisions of the PEI Electric Power Act.
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.

If you honked (or rang your bicycle bell), you'll want to watch our April 2018 Third Thursday webinar on electric vehicles, featuring Synapse experts Melissa Whited and Avi Allison.
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 testified on behalf of the Illinois Attorney General, recommending that Ameren should consider prioritizing low-income populations when implementing voltage optimization projects.
Sierra Club retained Synapse Energy Economics to analyze and comment on Arizona Public Service Company's (APS) 2018 Load Forecast Report. Synapse's analysis concluded that APS's latest report continued to fail to provide adequate justification for its projection of rapid and steady load growth in the face of a decade of flat load.
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.

The Southwest Energy Efficiency Project (SWEEP) conducted a study on benefits of residential heat pumps for space heating and water heating in five major cities in the Southwest. Kenji Takahashi of Synapse Energy Economics played a key advisory role assisting SWEEP with conducting the first major analysis of heat pumps against natural gas heating in the region. More specifically, he reviewed, advised, and offered recommendations on key assumptions and methodologies for evaluating energy, economic, and emissions impacts of heat pumps.
You can read the report on SWEEP's website.
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.
