May 12, 2009 May 12, 2009 Media Contact: Lauren Bartlett, (626) 302-2255 WILDOMAR, Calif., May 12, 2009 — Demonstrating its commitment to protect the environment while maintaining the reliability of the electricity system, Southern California Edison (SCE) has opened a new energy-efficient service center here that will allow the utility to respond more quickly to power outages in the southern part of Riverside County. The 19-acre complex, now home to nearly 300 employees, is 39 percent more energy efficient than similar buildings. The “green” building, powered by solar panels, was built to stringent standards developed by the Leadership in Energy and Environmental Design, commonly known as LEED, a national organization that certifies green buildings. State-of-the-art energy efficiency lighting allows for 90 percent of the interior spaces to have a line of sight to the outdoors. In addition, controls automatically raise and lower lighting levels based on natural light levels during the day. Among the water conservation features are low water demand landscaping and an underground water purification system that releases cleaner water into the environment. “The new service center in Wildomar is a model of energy efficiency, environmentally friendly and vital to providing optimum service to our customers in southern Riverside County,” said Cecil House, SCE senior vice president, safety, operations support and chief procurement officer. “It is really important to us to be in this growing community so we can better serve our customers’ needs.” Having nearly 300 people working in Wildomar, which has been impacted by tough economic times, will help put money into the local economy, from patronizing restaurants to gas stations. The location of the new service center also will allow SCE crews to more quickly respond to areas such as Temecula, Lake Elsinore and Canyon Lake. The crews previously were based in San Jacinto. “Southern California Edison’s opening of its green service center is an illustrative example of shared goals by the City Council and our community partner — combining sustainably developed materials and facilities that coexist with their surroundings,” Wildomar Mayor Scott Farnam said. “Having the new service center in our city also benefits our local economy, which is especially important during this economic downturn.” The new service center also will allow SCE to be a part of the community in a different way — it has a community room that holds nearly 270 people where some public meetings will be held.
