News Release Jules Layer Cooper Power Systems 763-543-7774 jules.layer@cooperindustries.com Aaron Parker Honeywell 763-954-4257 aaron.parker@honeywell.com COOPER POWER SYSTEMS AND HONEYWELL ANNOUNCE ZIGBEE 1.1 CERTIFICATION FOR SMART GRID TECHNOLOGY Joint Demand Response System Using Honeywell UtilityPRO® Thermostat and Cooper Power Systems Yukon™ Technology Meets ZigBee Standard, Gives Utilities and Homeowners Greater Control of Energy Use WAUKESHA, Wis., and MINNEAPOLIS, July 20, 2011 — Cooper Power Systems, a division of Cooper Industries plc (NYSE: CBE), and Honeywell (NYSE: HON) today announced the companies’ joint demand response system is one of the first technologies to receive certification for ZigBee® Smart Energy™ version 1.1, an open communication standard for smart grid products that help manage energy use and delivery. The system combines the Honeywell UtilityPRO® demand response thermostat with the Cooper Power Systems Yukon™ advanced energy services software and communication technology. The certification means the thermostat can receive demand response and other signals from the utility via the customer’s smart meter or in-home gateway. As a result, both utilities and homeowners can get detailed insight into energy consumption, and maximize the benefits of demand response technology and smart meter deployments. In addition, the ZigBee Alliance, the non-profit association that manages ZigBee standards, designated the UtilityPRO/Yukon system as a “golden unit,” making it a benchmark the alliance will use to test other products for Smart Energy certification. "Cooper Power Systems has a proven history of delivering solutions that enable utilities to maximize their investment, reliability, and customer participation," said Mike Stoessl, president of Cooper Power Systems. “Our technologies add intelligence and automation to the grid, from the substation to the home. This next generation of demand response communications demonstrates -MORE- 2-ZigBee 1.1 Certification interoperability among solution providers, plus it provides utilities more real-time load forecasting, verification and customer feedback.” Combining technology from Cooper Power Systems and Honeywell, UtilityPRO is the first touchscreen programmable thermostat designed exclusively for residential demand response programs. Effective demand response strategies help utilities temporarily reduce load on the electric grid when energy use and prices spike — typically on the hottest days of the year. UtilityPRO and Yukon enables a variety of control strategies that allow utilities to implement direct load control, dynamic pricing, and improve energy management through two-way communication. The collective decrease in demand helps stabilize energy prices, prevent disruptive brownouts and blackouts, and reduce the need for additional power plants. With the UtilityPRO advanced display and messaging capabilities, utilities can now deliver near real-time usage and billing data to the home, providing homeowners with better customer service, and greater control over energy decisions. Utilities can also confirm the thermostat is connected to the network and is taking action when it receives a signal from the utility. The Cooper Power Systems Yukon™ advanced energy services software is the engine behind the thermostat. It is a robust platform with an integrated delivery process and Web-based management dashboards that provide visibility into program performance and other metrics. The software offers utilities more communication choices than any other solution, along with additional two-way features and a solid migration path for the future. The collective decrease in demand helps stabilize energy prices, prevent disruptive brownouts and blackouts, and reduce the need for additional power plants. “An electrical grid that’s more intelligent and robust will engage the consumer in new ways,” said Kevin McDonough, director of Honeywell Utility Solutions. “Adding ZigBee communication to UtilityPRO empowers smart energy users, and helps maximize the investment utilities and regulators are making to modernize the grid. It’s an important link between the smart metering infrastructure and utility customers in the home.” Thirty-three utilities in the United States and Canada have already selected UtilityPRO and Yukon for their demand response programs, providing combined control of more than 500 -MORE- 3-ZigBee 1.1 Certification megawatts of peak energy use. The long-term collaboration between Honeywell and Cooper has delivered more than 500,000 programmable communicating thermostats for programs across North America.
