At the request of the Massachusetts Office of the Attorney General, the Connecticut Office of Consumer Counsel, the Maine Office of the Public Advocate, and the New Hampshire Office of Consumer Advocate, Synapse analyzed the impact that the FERC’s incentive pricing policy would have on New England transmission costs. The report details the results of that analysis based on estimates of the value of New England’s transmission facilities, as well as the value of facilities proposed for construction over the next several years.
Synapse performed a comprehensive assessment of the emissions impacts of demand response programs in New England. As ISO New England continues to refine its nascent electricity markets, there is widespread interest in facilitating demand response (DR) -- the ability for customers to respond to high prices by reducing electricity use or producing their own electricity onsite. There is also widespread interest in the net air emissions impacts of DR.
Synapse assessed the net emissions impacts of selected DR programs using the PROSYM/PROMOD dispatch model. The programs assessed included the economic DR program proposed by ISO New England for the summer of 2003, an economic DR program proposed by the New England Demand Response Initiative (NEDRI) for the summer of 2004, and several scenarios that explored key variables and uncertainties in these programs. In addition, Synapse modeled several energy efficiency programs in order to compare the emissions impacts of these programs to the DR programs. For all programs assessed, Synapse explored both the emissions impacts of DR operation and the impacts of new DR capacity on ISO unit commitment. Project completed in May 2003.

Synapse worked on a two-phase project focusing on electricity industry policies on clean power and energy efficiency. Phase one identified and summarized clean power and energy efficiency programs that were planned or on-going. The survey focused on initiatives within the Ozone Transport Commission (OTC) States, but also identified certain promising options from other states. The purpose of the survey was to provide information in a consistent format on each of the programs, and to identify which programs or program aspects were worthy of additional study as OTC continued its clean energy initiative. The survey was submitted to OTC in January 2002. The second phase was a more in-depth review and technical analysis of specific policies or issues pertaining to clean power and energy efficiency. Project completed in July 2002.
Predicting Avoided Emissions from Policies that Encourage Energy Efficiency and Clean Power
Survey of Clean Power and Energy Efficiency Programs
Synapse developed a quantitative tool to estimate emission reductions from a wide variety of energy policies in the Northeast. The tool was designed to assess three types of energy policies: policies that encourage energy efficiency and new clean generation, emissions portfolio standards, and multi-pollutant regulations targeting groups of existing power plants. Synapse used the PROSYM/PROMOD dispatch model to perform detailed marginal emissions analyses of the New England, New York, and PJM power control areas. The quantitative results of these analyses were embedded in a Microsoft Excel workbook designed to allow users to estimate emission reductions from different energy programs. Users of the workbook have the option to use the data on marginal emission rates developed by Synapse or to use other input data. Changes can easily be made in the workbook to represent different policy design decisions and assess the results of these decisions. The "OTC Emission Reduction Workbook" is available on both the OTC and Synapse websites. Project completed in December 2002.
