WRI Weingarten Realty Investors

BELTSVILLE, Md., May 21 /PRNewswire/ -- SunEdison, North America's largest solar energy services provider and a subsidiary of MEMC Electronic Materials (NYSE: WFR), today announced an agreement with Weingarten Realty Investors (NYSE: WRI), a real estate investment trust, for the deployment of up to 10 MW of PV solar power plants in Arizona and New Mexico.  By leasing space on Weingarten's underused rooftops SunEdison will install and operate solar energy systems that will allow Weingarten to convert underused roof space into a source of new revenue.  Once a system is operational, Weingarten Realty Investors will purchase the energy for common areas, and/or allow their tenants to realize energy savings by choosing to purchase power generated through the program at or below average retail energy rates.

"This program with SunEdison will provide Weingarten and its tenants with predictable energy costs," said Bill Goeke, Senior Vice President, Property Management of Weingarten Realty Investors. "SunEdison brings proven expertise in structuring, financing and operating large-scale solar projects. Having green buildings is obviously good for the environment, and we expect the rooftop PV systems to become a significant amenity we will use in marketing our properties."

"Weingarten Realty Investors understands how to think creatively about deal structure and tenant amenities," said Brian Jacolick, General Manager, Americas for SunEdison. "This agreement delivers on that thinking in a way that will reduce electricity costs and enhance property values.  We look forward to a long, productive partnership."

SunEdison and Weingarten are currently investigating additional deployment opportunities in other regions of the United States.
