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.

Review of the 2017 Nova Scotia Load Forecast.
Comments on NSPI Reply Evidence
On behalf of Counsel to the Nova Scotia Utility and Review Board (NSUARB), Synapse assessed Nova Scotia Power's (NSPI) advanced metering infrastructure pilot proposal in 2017. NSPI requested approval to deploy advanced (“smart”) meters to up to 1,000 customers at a cost of $8.2 million. Ms. Alice Napoleon identified multiple issues with the proposal, including, among other things, that the pilot period would neither provide sufficient time for data collection nor cover the period of highest system demand; that the pilot’s size was not adequately justified; that complementary programs to help customers experience the benefits from implementation of AMI were omitted; and that the proposed network for the pilot is not consistent with the network that may be required for full implementation. The evidence concluded that the design of the proposed pilot would not provide a solid basis for determining whether the costs and benefits associated with AMI justify a full roll out. Ms. Napoleon recommended that NSUARB not approve the current pilot application based on the current record of evidence. To address deficiencies identified by Ms. Napoleon and others, NSPI withdrew its initial AMI application and stated its intention to submit an amended filing.
In October, 2017, NSPI submitted an application to implement AMI throughout its service area. The application requested Board approval of a capital work order for $133 million to replace about 495,000 conventional meters with smart meters over the period 2018 to 2020. In early 2018, Alice Napoleon submitted evidence on behalf of the NSUARB regarding NSPI's proposal. Specifically, the evidence considered: 1. cost effectiveness of the proposal, including the magnitude of and support for claimed benefits such energy savings associated with critical peak pricing; 2. the reasonableness of allowing a return on the conventional meters to be replaced; and 3. coordination with the energy efficiency utility, EfficiencyOne, to enable benefits of the meters to be realized. In response to this evidence, NSPI submitted a sensitivity analysis to more fully consider the downside risks. The Board approved NSPI’s proposal subject to conditions but disallowed a return on the existing meters.

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. As part of the project, Synapse submitted evidence on its assessment of EfficiencyOne’s proposed 2019 Demand Side Management Resource Plan.

2019 NS DSM Plan Evidence Napoleon M08604
In 2018, Prince Edward Island Energy Corporation (PEIEC) filed an application (the Application) for approval of its 2018-2021 Energy Efficiency and Conservation Plan (Plan) with the Prince Edward Island Regulatory and Appeals Commission (the Commission or IRAC). Carr, Stevenson, and MacKay hired Synapse Energy Economics, Inc. (Synapse) to assess the Plan, in particular whether the Plan is likely to satisfy legislative requirements. To this end, Synapse reviewed the Application, issued information requests, and sponsored an expert report. The report considered the reasonableness of PEIEC’s Plan in terms of scope, cost allocation, and projected savings, participation, costs, and benefits. The expert report built upon Synapse’s 2016 comprehensive, best practice report for PEI on energy efficiency program and policy requirements. Project completed May 2019.
On behalf of the Keystone Energy Efficiency Alliance (KEEA), Synapse Energy Economics (Synapse) analyzed the potential impact on energy savings, economic benefits, and net-benefits from expanding the state’s utility energy efficiency programs by increasing budgets beyond the current budget cap. Synapse examined both a Base Case scenario and an Alternative Case scenario for 2021 to 2025, the period immediately following the Phase III programs. The Alternative Case illustrates a future with more robust energy efficiency programs, possible only if state policy makers remove the budget cap before the start of the next program phase in 2021. Under the Alternative Case, we project Pennsylvania ratepayers will enjoy incremental benefits of $1.2 billion with incremental savings of about 330 MW, equivalent to a single small natural gas power plant.
Synapse was retained by the Alliance for Clean Energy New York to develop an analysis of the role of existing renewable generation in achieving New York’s goal of 50 percent renewable energy by 2030. The report shows that so-called “Baseline” resources, which New York policymakers assumed would keep their energy and attributes in New York through 2030, have other markets for their production. If those resources are exported, New York would be forced to acquire substantial additional new renewable generation. Synapse analyzed policy options to compensate existing renewable resources for retaining their attributes in New York, and showed that they are less expensive than developing new renewable resources.
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.

Sierra Club retained Synapse to assess the 2017 Integrated Resource Pan (IRP) filed by Puget Sound Energy (PSE). Synapse's review found that the PSE IRP included a reasonable near-term resource plan but contained proposed actions that could lead to an unjustified deviation from that resource plan. In addition, Synapse identified a series of unjustified assumptions and conclusions regarding renewable resource costs and availability and coal plant retirement dates that resulted in a biased long-term resource plan. In comments submitted to the Washington Utilities and Transportation Commission, Synapse recommended that the Commission ensure full oversight of PSE's upcoming resource procurement processes and require PSE to use updated assumptions and enable full stakeholder participation in future IRP cycles.
Synapse provided analysis and expert testimony on behalf of Southern Alliance for Clean Energy for North Carolina's 2018 Avoided Cost Docket, no. E-100, Sub 158. Witness Devi Glick submitted responsive testimony on the topic of Battery Storage and PURPA Avoided Cost Rates.

Join us as we trace the evolution of a new reliability standard that the Federal Energy Regulatory Commission (FERC) appears to be endorsing as a part of its docket on resiliency. The FERC rejected the U.S. Department of Energy's recent request for an immediate FERC rule-making to support “fuel-secure resources.” Instead, the FERC initiated an administrative docket (AD 18-7) to solicit comments from RTOS and stakeholders on how to meet new reliability concerns related to fuel storage. Two recent FERC Orders suggest that the FERC is not waiting for a resolution of the AD 18-7 process before directing RTOs to modify their tariffs to “support” necessary resources whether through capacity market enhancements or through cost-of-service agreements. In this webinar, recorded live on July 19th, 2018, Synapse's Paul Peterson provides a play-by-play analysis of these ongoing actions and developments related to reliability.
We then take a deep dive into distribution level reliability, using New Jersey as a case study. Max Chang leads a discussion on how utilities and the New Jersey Board of Public Utilities have invested in distribution infrasture to withstand future large-scale storms in the aftermath of major storm events in 2011 and 2012: Hurricane Irene, the October '11 snowstorm, and Superstorm Sandy.

For the January edition of Synapse's Third Thursday webinar series, we talked strategic electrification with Asa Hopkins, PhD, Kenji Takahashi, and Danielle Goldberg.
Dr. Hopkins led a big picture discussion on issues that come up for regions that adopt strategic electrification as a strategy for decarbonization, including what quantitative work can be done to assess the opportunity strategic electrification represents, and its impact on the electric system. He provided helpful examples drawn from Synapse's recent work analyzing strategic electrification opportunities in New York and New England for the Northeast Energy Efficiency Partnerships. Kenji Takahashi and Danielle Goldberg then got into the nitty gritty details of a specific efficiency electrification technology: cold climate heat pumps. Mr. Takahashi and Ms. Goldberg have analyzed heat pump cost-effectiveness by examining various scenarios of fuel switching from fossil fuel heating to cold climate/advanced heat pumps. This includes retrofits, early retirements and new construction for different baseline fuels.
Bruce Biewald, CEO and Founder of Synapse, moderated the discussion, which took place on January 18, 2018.
Synapse was engaged by the Newfoundland and Labrador Board to provide detailed technical support during a first-phase review of “rate mitigation” approaches associated with the impending start-up of the Muskrat Falls hydroelectric generating station in Labrador. Synapse evaluated the Province’s load forecast, the potential for beneficial electrification and more aggressive energy efficiency policies, and the amount of surplus energy available for export. Synapse also addressed time-of-use and related rate design issues, and provided a more in-depth analysis of all issues during a second phase of work in 2019.
Phase 2 Report on Muskrat Falls Project Rate Mitigation
On June 21, 2018, Synapse Energy Economics and Robyn DeYoung from the U.S. Environmental Protection Agency presented a webinar about the Avoided Emissions and Generation Tool (AVERT). AVERT is an open-access tool built for the EPA by Synapse and ERG to estimate the hourly emissions and generation benefits of energy efficiency and renewable energy policies and programs. AVERT allows non-expert users to measure displaced HOURLY emissions of CO2, SO2, PM2.5 and NOX, and avoided generation mitigated by local, state, or multi-state programs. Stakeholders and regulators can also use the outputs of the tool for air quality modeling and to estimate public health benefits. Advanced users can also develop a near-term future scenario by retiring, replacing, or retrofitting with pollution controls. AVERT uses public data reported to the EPA by power plants in the United States.
New to AVERT? Watch this webinar to see it in action! Already familiar with AVERT? This webinar is your opportunity to learn about the exciting 2018 updates.

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.
We've spent early 2018 absorbed in data recently released by the U.S. Energy Information Administration (EIA). We've been analyzing numbers, creating snappy data visuals, and preparing the Synapse Electricity Snapshot 2018 (available here). In this webinar from March 16, 2018, we discuss the historical trends we found. We also look to the future by reviewing EIA's 2018 Annual Energy Outlook projections for energy use from the electric power, residential, commercial, and transportation sectors through 2050.
In typical Synapse style, we walk through the data using some of our favorite interesting graphs and charts.

Sierra Club retained Synapse to review the input assumptions and modeling methodologies underlying the 2017 Integrated Resource Plans (IRP) filed by Arizona Public Service Company (APS) and Tucson Electric Power Company (TEP). In comments submitted on behalf of Sierra Club, Synapse presented evidence that APS's plan to build thousands of megawatts of new natural gas-fired capacity was based on a series of analytical errors and flawed assumptions including an unrealistically high load forecast, under-statement of available cost-effective energy efficiency, inflated renewable costs, and deflated natural gas prices. Synapse recommended that APS hold off on procuring new gas capacity until it had produced an analysis containing a more reasonable set of assumptions. In comments on TEP's IRP, Synapse recommended that TEP revise its modeling to capture a wider range of scenarios and potential portfolios, and more rigorously assess the economic status of its coal units. Citing Synapse's comments, the Arizona Corporation Commission declined to acknowledge the IRPs submitted by APS and TEP, and imposed a series of requirements to ensure that future IRPs incorporate reasonable load-growth scenarios and evaluate a reasonable range of portfolios and sensitivities.

Southern Alliance for Clean Energy engaged Synapse to provide technical support regarding the Tennessee Valley Authority’s electricity rates. Synapse reviewed trends in electricity prices for industrial and residential customers to assess whether TVA allocates costs across customer classes fairly. Synapse published a white paper on our findings, "Electricity Prices in the Tennessee Valley: Are customers being treated fairly?"
Synapse reviewed ISO New England’s Operational Fuel Security Analysis (OFSA) study published in January and compared the model results with alternative scenarios suggested by New England stakeholders. The report shows how assumptions about demand for energy (electric and gas) and variations in supply resources might impact grid operations and reliability during an extreme winter in 2024/25. The report finds that using reasonable assumptions about demand and supply resources show minimal grid operation concerns and no rolling blackouts. This finding is starkly different from the ISO’s conclusions in its January OFSA study.
Our report was prepared for Conservation Law Foundation, with support from the Barr Foundation, on behalf of a group of NEPOOL participants that requested that additional scenarios be modeled as part of ISO New England’s OFSA.
Maintaining Reliability Under Extreme Conditions: Understanding ISO New England's Operational Fuel Security Analysis
Synapse was awarded a Conservation Applied Research and Development (CARD) grant by the Minnesota Department of Commerce to produce a white paper with recommendations on updates to Minnesota's energy efficiency cost-effectiveness framework. The objective of this project was to describe how the key elements of the National Standard Practice Manual (NSPM) could be applied to energy efficiency cost-effectiveness analyses in Minnesota. To determine how the NSPM’s principles could be applied to Minnesota’s cost-effectiveness framework, Synapse examined Minnesota’s current energy efficiency screening policies and practices and interviewed stakeholders. We used the Resource Value Framework (RVF) described in the NSPM to recommend a Minnesota-specific test as the state's primary test.

Dr. Asa Hopkins provided testimony before the District of Columbia PSC on behalf of the District of Columbia Department of Energy and Environment. Altagas proposed to acquire the District’s gas distribution utility, and Dr. Hopkins testified regarding the suitability of Altagas as a purchaser in light of DC’s goals for greenhouse gas emissions reductions. His testimony included an analysis of the long-term potential for natural gas consumption in the District in the context of an 80 percent GHG emissions reduction across all sectors, and concluded that dramatic reductions in fossil fuel gas consumption are going to be necessary, that renewable natural gas supplies are unlikely to make up the difference, and that WGL would need to change aspects of its business model as the city moves toward its goals. Dr. Hopkins testified regarding the suitability of Altagas’s merger commitments to the District’s GHG goals in light of these conclusions.
