HOUSTON, February 19, 2008 -- Cooper Power Systems, a division of Cooper Industries, Ltd. (NYSE: CBE), announced today that it has been selected by Baltimore Gas and Electric Company (BGE), a subsidiary of Constellation Energy, to provide a system for peak demand reduction designed for BGE’s residential customers.  The Cannon Demand Management solution, which is a product of Cooper Power System’s Energy Automation Solutions (EAS) group, supports a number of BGE goals including ensuring system reliability and helping customers manage their energy use.  Cooper expects the project will represent $42 million in revenue over the period 2008-2011—and when expanded to full capacity, it will provide more than 600 megawatts of clean energy capacity by 2011.

Cooper Power Systems’ EAS group is providing BGE a solution comprised of its Yukon enterprise software, along with a combination of state-of-the-art smart thermostats and control switches utilizing a wireless communications system.  “With the largest demand response business in North America, Cooper is committed to supplying world-class technology solutions that assist our utility customers in improving service reliability while providing clean energy and reducing customer bills,” said Cooper Power Systems President Mike Stoessl,  “The Cannon Demand Management solution will support the combined needs of BGE and EmPOWER Maryland (the State’s energy consumption reduction initiative) - satisfying their common goal to reduce energy use and provide bill savings to the end consumer.”

 “BGE selected the Cannon Demand Management solution after a thorough evaluation process,” said William Pino, director of electricity supply and forecasting for BGE. “BGE announced its Smart Energy Savers ProgramSM in January of 2007, and during the summer successfully piloted the residential demand response program to support a reduction in peak electric demand usage and energy conservation efforts. BGE’s Smart Energy Savers ProgramsSM is a customer-focused service tailored to give residential consumers more options for managing their energy costs. The program includes several initiatives such as Cannon’s Demand Management solution utilizing smart thermostats and air conditioner load control switches, energy efficiency/conservation programs (such as rebates for energy efficient appliances and discounts for compact florescent light bulbs) and advanced metering (smart meters) to facilitate dynamic pricing options for our customers.”
