Cooper Power Systems Introduces New Demand Response Device

Cooper Power Systems, a division of Cooper Industries plc (NYSE: CBE), is helping homeowners become better consumers of electrical power with the introduction of the company’s new, in-home, peak load indicator. The wall outlet-sized, plug-in indicator, developed in cooperation with Delaware Electric Cooperative, utilizes colored LED lights to notify customers when a peak power use period is approaching or underway.

The indicator contains a series of LED lights to inform consumers of either approaching or occurring peak power use periods, advising them to reduce consumption. Consumers are informed that reduced energy use during peak power periods could have a significant impact on both the power delivery system and on the customer’s monthly electric bill. Using the Cooper Power Systems Yukon Advanced Energy Services Platform, the in-home indicator receives hourly signals from the utility to confirm that continuous communication is taking place.

The Cooper Power Systems in-home indicator is an expansion of Delaware’s "Beat the Peak” program, an effort to increase communication with customers and reduce electricity use during peak times. In 2008 the company’s technology helped Delaware Electric save more than $2 million, by minimizing power requirements during monthly peak periods.

"Our members now help us manage our peak load demands by responding to Beat the Peak signals played on the radio, on television, or sent in e-mail or text messages,” said Bill Andrew, President and CEO of Delaware Electric Cooperative. "With Beat the Peak we’ve been able to cut our rates in the face of rising costs. The in-home indicator is key to the long-term effectiveness of that program.”

The in-home indicator is offered free of charge to Delaware Electric Cooperative members. The Co-op recently signed an agreement with Cooper which will enable it to install the devices in more than 40,000 homes in its service territory. Once installed, Delaware solicits feedback from consumers on the effectiveness of the device and how it is being utilized in each home.

"The in-home indicator is the result of Cooper Power Systems listening to and working with our customers to meet their needs,” said Tom Pitstick, Vice-President and General Manager of the Energy Automation Solutions division at Cooper Power Systems. "Delaware is a forward-looking cooperative and ideas like this will help shape the future of the Smart Grid and electric power delivery.”
