Stonewater Customer, The Energy Coalition, Wins Award for Innovative Program Design

Evanston, Illinois — March 16, 2006 — Today the Business Energy Coalition Program in California received the award for Innovative Program Design from the Peak Load Management Alliance (PLMA). This program, managed by the Irvine, California-based Energy Coalition, is an initiative between Pacific Gas and Electric Company (PG&E) and more than 30 major San Francisco business and civic leaders.

Stonewater was selected by The Energy Coalition to provide its energy1st platform to support the Business Energy Coalition Program. Using Stonewater's web-based software suite for aggregated energy analysis, remote device management, curtailment event notification and performance reporting, program members get a near real-time, web-based view of their own and the entire cooperative's electric consumption. Stonewater's platform also provides instant communication and feedback among coalition members. In making the award, PLMA noted that the program was innovative in providing a comprehensive strategy, including energy analysis and metering and monitoring tools.

"The energy1st system is one of the key elements to the success of the Business Energy Coalition group load curtailment program," said Leanne Hoadley, Program Manager. "We are able to instantly and continuously monitor and verify our group's demand reduction. This makes the program viable for the utility and, in the long-term, the entire state of California."

The pilot project was launched on July 1, 2005, to allow large electric users who normally would find it difficult to participate in demand response programs to join forces to reduce electric energy use during peak demand days and help avoid power shortages. Between July 1, and December 31, 2005, seven "Energy Action Days" were called, totaling 31 hours and resulting in an average load reduction of 14.6 MW per event (146% of the program's 10 MW goal).

Stonewater provides real-time, two-way control capability to monitor and control thousands of machines and sensors simultaneously and securely over the Internet. Stonewater customers are able to view any number of remote sites from any location worldwide and manage data from a variety of manufacturers and equipment types.
