other SESCO Projects 



All of SESCO's conservation projects have been performance-based energy 

 services contracts with the host utility, which pays SESCO based exclusively upon 

 the savings measured at the treated homes. No charge is made to the host 

 household. 



Central Maine Power Co.'s 20,000 house, $25 million "Project HouseWise" is 

 the nation's largest contract for residential conservation. Begun In 1992, it is about 

 40% complete. 



New York State Electric & Gas Co.'s "Free Power Project" with SESCO, an 58 

 million, 10,000 house residential project, is the largest residential performance 

 contract in New York. Begun in 1993, it is about 10% complete. 



Rockland Electric Co.'s "Free Power Project" with SESCO in northern New 

 Jersey treated essentially all (about 4,700) of that small utility's electric heat 

 customers. Savings during the first year have averaged 2,200 kWh per house, for 

 utility bill savings of about $280 annually per household. 



Central Maine Power Co.'s "Power Partners" program treated 9,700 houses 

 during 1990-92. Annual savings during the past three years have averaged 2,560 

 kWh per household. 



Commonwealth Edison Co. (Chicago, IL) treated 1 ,000 multi-family units 

 during 1988 and 1989 under its performance contracting REEP ("Residential energy 

 Efficiency Program"), making it the largest performance contracting project exclusively 

 for multifamily customers. Annual savings, which included common area treatments, 

 averaged over 3,000 kWh per treated customer. 



SESCO treated 5,550 Western Massachusetts Electric Co. (WMECO) electric 

 water heating customers in 1986-1987. Although only about half were also electric 

 heat customers, annual savings during the three years after treatment averaged 

 about 2,000 kWh per customer.
