Solar Power Raises the Score for the Colorado Rockies


Coors Field Celebrates First Utility-Scale Solar Power Electric System in a Major League Ballpark

DENVER, April 20 -- This weekend, the Colorado Rockies will take on the San Diego Padres at home under a solar-powered scoreboard. The new 9.9 kilowatt solar electric system, which was installed by Independent Power Systems as a result of a partnership between the Rockies and Xcel Energy, is being celebrated on Earth Day, April 22. Comprised of 46 solar panels from SunPower Corporation (NASDAQ:SPWR), it is the first commercial- scale solar electric power system to be installed in a Major League Baseball ballpark.

The new system covers an area of 616 square feet and will produce more than 14,000 kilowatt hours of energy, enough to offset energy consumption by the Rockies' 'Rockpile' LED scoreboard for over a year. A flat-panel monitoring system shows fans at the ballpark real time system performance and scoreboard energy use, and the same data is available on-line at www.solarips.com/coors.

"This solar project delivers on the Colorado promise of the 'New Energy Economy' that I have been speaking about all over the state," said Colorado Governor Bill Ritter. "I congratulate the Rockies for their leadership and call upon Major League Baseball, the NFL, and stadium owners throughout the nation to follow the example we've set by deploying solar at Coors Field."

Independent Power Systems, a SunPower Premier Dealer, designed and installed the system in two weeks, just in time for the Rockies' season opener. "We designed the system to ensure that no glare from the solar panels will reach players on the field," said Independent Power Systems President Tony Boniface. "SunPower solar panels were the perfect choice for this project because they offer the highest efficiency on the market."

"Solar power is an essential component of our global energy mix, and companies such as Independent Power Systems and Xcel Energy are doing their part to ensure that it is an easy, affordable option for home and commercial use," said Tom Werner, chief executive officer of SunPower. "The Rockies have distinguished their organization as a leader, by bringing clean, renewable energy to a great American sport."

"We were pleased to partner with the Rockies on this project," said Pieter Leenhouts, director of strategic marketing at Xcel Energy. "This Earth Day, Rockies fans can celebrate their team's commitment to helping take America to a new level of energy independence."

Solar rebates from Xcel Energy helped offset the cost of the system for the Rockies. Similar rebates are available to both commercial and residential customers of Xcel Energy.
