#116 – EXECUTIVE SUMMARY
Boston Edison Company
Large Commercial & Industrial Retrofit

Boston Edison’s Large C/I Retrofit program for customers that have an average monthly demand greater than 150 kW is an example of a highly sophisticated, but "conventional" incentive-based DSM program. While its generous direct incentives may soon be a thing of the past, many of its program design elements -- such as market segmentation, financing options, and verification guidelines -- will likely be highly applicable to future programs that will serve both customers’ needs and shareholder profitability in the future.

The Large C/I program exemplifies a refined approach to market segmentation and customer financing options. For instance, a customer can elect one of three program tracks depending on the complexity of his or her retrofit. The program is further subdivided based on whether or not the customer is an institutional or non-institutional customer, since institutional customers tend to have even more restricted access to capital than their private-sector counterparts. Furthermore, while the utility has been increasing the required customer contribution over time -- and BECo plans to require a 100% customer contribution by the year 1998 -- customers have had two basic fundamental options: They can either utilize the program’s 100% financing option and receive smaller incentive rebates, or they can finance the retrofits independently and collect a commensurately larger incentive. In fact, staff consider three important parameters for incentive payments: who pays for audit costs, the timing of payments, and incentive levels. Institutional customers, for example, can finance audit costs. Non-institutional customers, on the other hand, receive incentive payments based on quarterly verification of program savings.

The Large C/I program also has had a heavy emphasis on metered savings using BECo’s Verification Guidelines, a protocol for establishing confidence in program savings. BECo, like many utilities, is moving away from engineering estimates of savings and now demands greater accuracy and consistency from savings. (A BECo evaluation of school retrofit savings suggested that the utility expected nearly twice the level of savings than it actually achieved.) Thus BECo has placed a great deal of attention on determining "net savings" using rigorous in-house and external evaluations and "true-ups" in subsequent years. Free ridership, for example, has been backed out of program impacts. Through the true-ups BECo has squarely addressed persistence of installed measures. Furthermore, the utility has maintained a keen interest in programs’ load shape impacts.

Despite the program’s basic transition, it has nevertheless racked up impressive impacts. During 1992 and 1993 alone, the program resulted in annual energy savings of 32 GWh and nearly 8 MW of capacity from a total, two-year expenditure of just $28 million. Lighting accounted for 79% of the savings. The commercial sector contributed nearly 80% of the total savings; within the commercial sector, colleges provided the majority of the savings followed by offices.

The Results Center Profiles:  The results center


In the early and mid 1990s The Results Center produced 126 case studies of the most successful energy efficiency and renewable energy programs in the United States and around the world. With the support of the John D. and Catherine T. MacArthur Foundation, Ted Flanigan directed a research team at Colorado-based IRT Environment to produce and distribute these exceptional examples. Thanks to strong demand for case studies, The Results Center was supported by dozens of major utilities and energy associations worldwide. The Results Center is again producing the case studies it has been known for, still under the direction of Ted Flanigan, but now at EcoMotion Incorporated, a firm focused on strategic consulting, information dissemination, program design, outreach services, and aggressive implementation.
