Using the Coactive Connector(R) Internet gateway with Silicon Energy's EEM Suite(TM) and MSP (managed service provider) hosted value-added services, corporations and service providers will be able to use the Internet to monitor real-time energy usage across homes and businesses; use intuitive visualization software to analyze energy usage; implement load management and alarming; link to billing and accounting; and significantly reduce operating costs enterprise-wide.

"The partnership between Coactive and Silicon Energy will further allow energy service providers to deliver customized value-added solutions to their clients," said John Woolard, president and CEO of Silicon Energy. "We believe commercial and residential customers will both benefit by being able to manage energy usage, control costs, and negotiate more favorable rates."
