The Union of Concerned Scientists (UCS) retained Synapse to review, from a public policy perspective, the merits of long-term power purchase agreements (PPAs) between developers of wind power projects and providers of retail electric supply service (“load serving entities” or LSEs) in restructured electric markets. This review found that long-term PPAs encourage the development and/or expansion of wind power projects. Using Massachusetts as a case study, Synapse found that long-term PPAs provide several important benefits to customers of the contracting LSEs in particular, and to the Commonwealth of Massachusetts (Commonwealth) in general. The benefits of the PPAs to the customers of the contracting LSEs include mitigation of price volatility, mitigation of future increases in prices and reduction in the cost of RPS compliance reflected in those prices. In addition, because long-term PPAs encourage the development and/or expansion of wind power projects, they provide additional benefits to the customers of the contracting LSEs, and to the Commonwealth in general, in the form of reductions in dependence on natural gas, increased generation diversity, and reductions in emissions of carbon dioxide.
Synapse was hired to analyze the costs and effectiveness of supply-side and load-side up approaches for state carbon reduction policy for the electric power sector. Bruce Biewald prepared a simple Excel model and presented the results to CPUC/CEC.

Synapse investigated a number of issues in a rate case: 1) whether Arizona Public Service’s (APS) acquisition of the Sundance Generating Station was prudent; 2) whether the amounts that APS requested for Operating & Maintenance expenditures (“O&M”) for the PWEC Units and the Sundance Plant were reasonable; and 3) the generation and associated costs included in APS’ base rate application. Synapse found that APS’ acquisition of the Sundance Plant was reasonable and prudent. However, we found that the Company’s requested power plant O&M was unreasonably high and should be reduced for both plants. Project completed in February 2006.

Synapse evaluated the potential benefits and costs associated with the deployment of Broadband Over Power lines (BPL) in a utility’s service territory. The potential benefits of BPL include the ability to use the existing power lines and the wiring inside homes and other buildings to offer enhanced energy services and load control, to facilitate the use of distributed generation, for automatic meter reading, to provide internet and other informational services to customers, and for increased system monitoring and outage detection. Project completed in March 2006.
Synapse was asked to evaluate alternatives to the Broadwater LNG import facility, proposed as a floating storage and regasification facility to be located in Long Island Sound. Synapse concluded that the region does not have a pressing need for a new baseload resource to provide natural gas, and the region's energy needs for the next decade can readily be met through energy efficiency, implementation of existing renewable energy goals, expanded use of combined heat and power, and repowering of existing power plants. Finally, we found that there are other options for increasing gas supply to the region which would be far preferable to the Broadwater proposal. The most promising of these includes two LNG import facilities already under construction in Eastern Canada, together with the planned expansion of the Maritimes and Northeast pipeline from Eastern Canada into the northeastern United States. Project completed in February 2006.
