Nevada Power will unveil its newest Photovoltaic (PV) System with tracking arrays at
11 a.m. on Thursday, April 13 at the Clark Generating Station located at 5640 Stephanie Street (US 95& Russell).  Nevada Power executives, elected officials and community leaders will be on hand for a dedication and a demonstration of the Clark Photovoltaic System that will harness the sun's rays to generate additional, clean, and renewable energy.

The Clark PV Station consists of three dual-axis high concentrating photovoltaic tracking arrays that will produce 180,000 kilowatt hours of power that will be fed directly into the local electrical grid.  This is enough energy to power approximately 12 medium-sized homes in southern Nevada.

“This project is the start of many more to come and we are pleased that it has come to fruition,” said Roberto Denis, Nevada Power's vice president of energy supply. Ã¢â‚¬Å“We are committed to the development of renewable resources and will continue to look for opportunities to independently produce more projects like this one or to partner with other entities to better utilize alternative energy sources."

Over the year, the technology will provide up to 30 percent more energy than equally sized, traditional, fixed photovoltaic panels, which do not follow the sun's movement.  The units are programmed to seek the sun based on the astronomical time-clock and sun sensor, tracking it from the east in the morning to the west in the afternoon.  The technology utilizes magnification to concentrate the sun's irradiance to 500 times normal and focuses this energy on the photovoltaic cells to produce electrical power.

Headquartered in Nevada, Sierra Pacific Resources (NYSE:SRP) is a holding company whose principal subsidiaries are Nevada Power Company, the electric utility for most of southern Nevada, and Sierra Pacific Power Company, the electric utility for most of northern Nevada and the Lake Tahoe area of California. Sierra Pacific Power Company also distributes natural gas in the Reno-Sparks area of northern Nevada.
