Stonewater Expands the Business Energy Coalition's Demand Response Program for Pacific Gas & Electric for 2008

EVANSTON, ILLINOIS—August 1, 2007—Stonewater Control Systems is providing its Energy 1st platform to expand an innovative program in San Francisco that will give large power customers the opportunity to participate in a cooperative to reduce peak demand by a goal of at least 50 megawatts.

The Business Energy Coalition is a cooperative partnership between Pacific Gas & Electric Company and major San Francisco businesses, facilitated by The Energy Coalition, located in Irvine, California. Businesses participating in the program range from major hotel chains such as Marriott, Westin and Hilton to retail chains such as Gap to major technology giants such as Microsoft.

Using Stonewater's web-based Network Operating Center, members get a near real-time view of their own and the entire cooperative's electric consumption. Stonewater's system also provides instant communication and feedback among coalition members. In addition to reducing load on power plants during times of high electricity demand, the program aims to protect the transmission and distribution infrastructure. "We are pleased that Stonewater participated with us in the initial pilot for PG&E, and this has led to an expansion of the project to 50MW. Stonewater has helped us make demand response a reality in Northern California," said Leanne Hoadley, Program Manager for The Energy Coalition.

The Energy Coalition is a non-profit organization that has been in operation since 1981. The oldest energy cooperative in the United States, The Energy Coalition is dedicated to raising awareness among consumers, businesses and municipalities about smart energy management strategies for a healthy energy future.
