Nova Scotia is one of the last remaining Canadian provinces to consider adoption of the US FERC 888 pro forma tariff structure. Synapse evaluated the tariff application and provided expert witness testimony to the Board, focusing on issues that included generation interconnection standards, ancillary service rates, and reciprocity concerns. Project completed in September 2005.
Synapse reviewed numerous categories of documents provided by the defendants during discovery related to Clean Air Act lawsuits against American Electric Power Company and Cinergy Corporation and evaluated whether the public release of these materials would cause competitive harm to the companies. Project completed in January 2005.
The Connecticut DPUC has opened a proceeding to consider possible Alternative Transitional Standard Offers (TSOs) authorized by the legislature. On behalf of the Office of Consumer Counsel, Synapse prepared recommendations for how to structure and procure Alternative TSOs for both renewable energy and energy efficiency products made available to residential and small commercial customers who do not shop for competitive offers. Project completed in November 2004.
Synapse conducted an analysis of several case study utilities in PJM. Synapse estimated the unbundled pre-deregulation prices for the generation portion of bundled electric service and indexed those prices forward in time to allow for comparison with the deregulated generation service market prices. Project completed in August 2004.
Amy Roschelle and Paul Peterson presented “Best Practices in Procurement of Basic Electric Service for Residential and Small C&I Customers: The end of the transition period in Massachusetts” before the Office of Massachusetts Attorney General on May 17, 2004.
Synapse testified and prepared recommendations to the California PUC with regard to California's long-term resource plans for electric utilities. In particular, Synapse focused on making sure plans were clear, comprehensive, forward-looking, and integrated, especially with respect to renewables generation and energy efficiency. To do this, Synapse focused on the concept of scenario planning with respect to carbon emission regulation and gas price forecasts, as well as making sure that transmission lines would be in place to serve renewable generation facilities. In addition, Synapse examined the effect of debt equivalency on long-term contracts for renewables. As a result of our contribution, the CPUC lowered the value of debt equivalency on all long-term contracts. In addition, the CPUC adopted our recommendation regarding carbon and other greenhouse gas emissions with regard to their use in fossil fuel plants. Specifically, the CPUC will consider cleaner generation sources more cost-effective than fossil fuel plant generation sources if the cleaner generation sources prevent carbon emissions at a cost of less than $8 - $25 per ton. Project completed in December 2004.
Rebuttal Testimony Reviewing California Utilities Long Term Resource Plans
Synapse reviewed and reported on mechanisms designed to ensure resource adequacy for regions that have adopted ISO-administered competitive wholesale energy markets. These include demand curves as well as alternative mechanisms.
Synapse and Tellus Institute developed a plan for the aggressive implementation of energy efficiency and renewable resources in seven Interior West states. The analysis included PROSYM electricity market simulation modeling, a technical assessment of cost-effective energy efficiency opportunities, a technical and economic assessment of renewable resource potential, and the development of policies for overcoming market barriers to these clean resources. The study also assessed the role of renewable and distributed generation resources in addressing transmission constraints.

Bruce Biewald presented “Estimating Emissions Reductions from Energy Efficiency in the Northeast” at the ACEEE Summer Study in California in August 2004.
Building on our 2003 work for the North American Commission for Environmental Cooperation (CEC), Synapse analyzed several non-modeling based methods of estimating emission reductions from energy efficiency and renewable energy. Based on a review of numerous papers, Synapse identified three common methods of estimating emission reductions using simplifying assumptions about power system dynamics. Synapse assessed the extent to which each of these methods was likely to provide an accurate and credible assessment of emission reductions. The most promising method sought to identify the marginal generating unit(s) in the relevant system based on a load curve analysis. The report identified several aspects of this method that need to be further investigated to determine how robust the method is. Project completed in November 2004.
Synapse conducted a comprehensive assessment of BC Hydro’s Power Smart energy efficiency programs. The assessment included the review of program design, program cost-effectiveness, program budgets, and BC Hydro’s assumptions regarding program costs and benefits. The analysis indicated the Power Smart programs to be highly cost-effective and well-designed, and that the Company should pursue additional efficiency opportunities. Synapse also found that the rate impacts of the Power Smart programs are likely to be small and should not hinder the Power Smart programs or their expansion. The results of the analysis were provided in direct testimony of Tim Woolf, filed before the British Columbia Public Service Commission on April 20, 2004. Project completed in August 2004.
