Wal-Mart says in solar power pilot project

NEW YORK (Reuters) - Wal-Mart Stores Inc. said on Monday that as part of a new solar power pilot project, it is purchasing solar power from BP Solar, SunEdison LLC, and PowerLight for 22 combined Wal-Mart stores, Sam's Clubs and a distribution center in Hawaii and California.

The world's largest retailer, which is working toward the goal of one day being supplied by 100 percent renewable energy, said each solar power generating system installed can provide up to 30 percent of the power for the store on which it is installed.

"Pilot project stores are expected to achieve savings over their current utility rates immediately--as soon as the first day of operation," said David Ozment, director of energy for Wal-Mart, in a statement.

SunEdison will provide four solar power systems in Hawaii and four in California, while PowerLight and BP Solar will each supply seven systems in California.

PowerLight is a subsidiary of SunPower Corp.

The installations are subject to receiving the appropriate permits and approvals in their respective states, the company said.

Wal-Mart said the total solar power production from the 22 sites is estimated to be as much as 20 million kilowatt-hours per year.
