In support of New York State’s nation-leading GHG emissions reduction goals—targeting 40 percent reduction of GHG emissions by 2030 and 80 percent by 2050—the New York State Energy Research and Development Authority (NYSERDA) has begun a process of developing an integrated policy framework to address emissions from the heating and cooling sector. Synapse joined a group of consultants led by Meister Consultants to assist NYSERDA with this effort. More specifically, Synapse assisted NYSERDA and Meister with developing (a) a comprehensive database of costs and performance of Renewable Heating and Cooling (RH&C) technologies such as air-source heat pumps, geothermal heat pumps, solar hot water, and heat pump water heaters; (b) an Excel-based tool to analyze costs and benefits of RH&C technologies; and (c) a state RH&C Policy Framework report. As part of our effort to develop RH&C technology profiles, Synapse also participated in a stakeholder meeting by the Advisory Committee of industry stakeholders and experts and facilitated a working group on air-source heat pumps.

In 2016, Public Service Company of Colorado (PSCo) filed a request for rate design modifications, including a tiered monthly “Grid Use Charge” for all residential customers and a voluntary residential demand – time-of-use rate. The Company’s stated intent for the proposed Grid Use Charge was to act as an interim step before the implementation of a demand charge. On behalf of Energy Outreach Colorado, Synapse conducted an analysis of PSCo’s proposal and Tim Woolf provided expert testimony before the Colorado Public Utilities Commission. Synapse’s testimony challenged the Company’s proposal to move residential customers toward demand charges because such charges are inconsistent with fundamental rate design principles, create inefficient price signals, are complex and difficult for residential customers to respond to, place undue burden on low-usage and low-income customers, and may ultimately increase long-term electricity costs. Project ongoing.

New England’s growing dependence on natural gas has had some in the region worrying about supply constraints. In fact, concerns about natural gas supply and the impacts of proposed new pipelines prompted no fewer than three separate studies on the issue last year. In 2015, three consulting firms released separate reports for different clients analyzing the need for incremental natural gas pipeline in New England through 2030. The three distinctly different approaches to the studies have the potential to create uncertainty for those trying to compare the results. To address this confusion, Synapse produced a white paper which reviews the main differences in the methods and inputs for each of the three studies, along with their results and key findings.

Synapse reviewed the modeling methodology used by Portland General Electric (PGE) in the development of its 2016 Draft Integrated Resource Plan. Synapse found that PGE’s methodology lacked rigor and, as such, did not sufficiently justify its portfolio selection for the draft IRP. In comments submitted on behalf of Sierra Club during a stakeholder feedback process, Synapse recommended that PGE address the flaws in the selection process by (1) conducting optimization modeling, (2) performing a probabilistic analysis, (3) replacing its unreliable metrics with standard measures, (4) providing scenario results to stakeholders, and (5) involving stakeholders in future procurement decisions.

On behalf of Sierra Club, Synapse reviewed the Tucson Electric Power Company’s (TEP) rate application submitted to the Arizona Corporation Commission. Specifically, Synapse reviewed TEP’s decision to retire the San Juan Generation Station (SJGS) Unit 1 in 2027 and its request to recover costs from ratepayers for a $34 million investment in two pollution control projects at the unit. Synapse found that TEP did not exercise due diligence in supporting its recommendation of a 2027 retirement and its capital expenditures, relying heavily on another owner of the plant, Public Service Company of New Mexico. TEP conducted its own analysis in 2012 and 2013, prior to several major changes that affect the economics of San Juan. Synapse’s analysis found that the unit is unlikely to be economic after 2022. As such, Patrick Luckow submitted expert testimony recommending that the Commission reject the proposed 2027 retirement in favor of a 2022 retirement.

Synapse analyzed least-cost strategies for reducing emissions 40 percent below 1990 levels in Regional Greenhouse Gas Initiative (RGGI) states by 2030. Synapse’s analysis focused on four well-researched, cost-effective emission reduction measures: energy efficiency, wind and solar generation in the electric sector, and conversion from gas-powered to electric light-duty vehicles in the transportation sector. Using a purpose-built version of Synapse's Multi-Sector Emissions Model (MSEM) and the National Renewable Energy Laboratory’s Regional Energy Deployment System (ReEDS) model to emissions in the RGGI states, Synapse analyzed the impacts of adding the following measures to the RGGI states’ existing goals:

  • Converting one-third of all light-duty vehicles from gas to electric
  • Achieving Massachusetts’ level of energy efficiency savings in all RGGI states
  • Investing in onshore wind generation up to the economically achievable potential
  • Limited investments in utility-scale solar installations

Version 2.0 of the resulting report considers the gas and oil savings (co-benefits) from electric energy efficiency measures and the electric savings from gas energy efficiency measures. It also includes two new carbon dioxide emission reduction measures that were not considered in our original January 2016 report:

  • Gas energy efficiency measures in the residential, commercial, and industrial sectors
  • The replacement of aging residential oil heating systems with air-source heat pumps (efficient electric heating units)

In addition, this study:

  • revises the methodology for choosing which emission reduction measures to include in the modeling by incorporating the cost of powering electric vehicles with renewables;
  • reallocates the installation of onshore wind generators across Northeast states to be more consistent with expected wind speed potential; and
  • uses updated levelized costs of energy for onshore wind and utility-scale solar, reflecting the best information available at the time of publishing.
  • With these measures in effect, lower emission reductions are required of the electric sector to reach the same 40-percent all-sector emissions reduction target for the nine Regional Greenhouse Gas Initiative states.

Subsequent to this study, Synapse presented a webinar in which Synapse staff used RGGI as a case study to demonstrate the use of Synapse's Multi-Sector Emissions Model (M-SEM). View presentation here.

The thermal energy sector, which relies primarily on fossil fuels, accounts for approximately one third of Rhode Island’s total energy consumption and total carbon emissions. By diversifying the thermal energy sector to increase use of low-carbon renewable heating and cooling technologies (e.g., air source heat pumps, ground source heat pumps, wood pellet heating, solar thermal), Rhode Island can make significant strides toward achieving greenhouse gas emission reduction goals while producing substantial economic benefits for the state. To meet these objectives, the Rhode Island Office of Energy Resources tasked Synapse and Meister Consultants Group with (a) analyzing policies and programs designed to grow the renewable thermal industry and (b) conducting a detailed market model of an alternative thermal sector energy future. This market model analyzed the cost-effectiveness, energy rate and bill impacts, local job impacts, and emission impacts of an alternative future in which Rhode Island achieves five percent renewable energy penetration by 2035.

Jurisdictions across the country are grappling with the challenges and opportunities associated with rapidly increasing adoption of distributed solar resources. While distributed solar can provide many benefits – such as increased customer choice, decreased emissions, and decreased utility system costs – in some circumstances it may result in increased bills for non-solar customers. Utility regulators and state policy-makers face the difficult task of striking a balance between ensuring that cost-effective clean energy resources continue to be developed, and avoiding unreasonable rate and bill impacts for non-solar customers.

This report, prepared by Synapse for Consumers Union, provides a framework for helping decision-makers analyze distributed solar policy options comprehensively and concretely. This framework is grounded in addressing the three key questions that regulators should ask regarding any potential distributed solar policy:

  • How will the policy affect the development of distributed solar?
  • How cost-effective are distributed solar resources?
  • To what extent does the policy mitigate or exacerbate any cost shifting to non-solar customers?

Answering these questions will enable decision-makers to determine which policy options best balance the protection of customers with the promotion of cost-effective distributed solar resources.

The New York Public Service Commission has undertaken an ambitious initiative to improve system efficiency, empower customer choice, and encourage greater penetration of clean generation and efficiency technologies. Called the Reforming the Energy Vision initiative, or REV, this case has proceeded on two tracks. The focus of Track Two is to examine what regulatory changes in current regulatory, tariff, and market designs and incentive structures are needed to better align utility interests with achieving the PSC’s objectives. Synapse provided the Natural Resources Defense Council (NRDC) with analytical and policy expertise to help NRDC ensure that REV Track Two: (1) results in a regulatory and ratemaking model for New York that moves away from electricity as a commodity, (2) promotes the penetration of clean and renewable resources, (3) ultimately decarbonizes the electric sector, and (4) becomes a model for other jurisdictions. Synapse assisted NRDC in this matter by conducting and quantitative research and analysis to inform NRDC comments and proposals, developing and executing work plans for strategic engagement in REV Track Two, working with NRDC to draft submissions to the PSC, and otherwise participate in REV-related stakeholder processes, where required.

Synapse also assisted NRDC with Track One issues

One of the key benefits most attributed to energy efficiency and renewable energy (clean energy resources) is that they reduce the use of fossil fuel resources consumed for generating electricity, and in doing so reduce fossil fuel-related carbon dioxide emissions. Synapse reviewed a range of sources and compiled evidence that clean energy resources have indeed displaced generation by fossil resources connected to the grid, and that they are projected to continue doing so in the future. The report includes:

  • utility-level case studies of electric system integrated resource planning (IRP) model results;
  • a review of national-level analyses;
  • an overview of marginal resources in different regional transmission organization (RTO) areas;
  • modeling case studies using EPA’s AVERT; and
  • a review of historical data demonstrating the impact that energy efficiency and renewable energy have already had on fossil fuel use.

In addition, the report highlights original Synapse analysis using the ReEDS model on the impacts of expanding clean energy resources on emissions related to fossil-fuel generation.
