Significantly expands NRG Energy's residential solar business Complements existing network of installers

PRINCETON, N.J.--NRG Energy, Inc. (NYSE:NRG) has acquired one of the nation's leading residential solar companies, Roof Diagnostics Solar (RDS), to support and expand the company's efforts to empower its customers to control their own energy destiny through clean self-generation. RDS will complement NRG's extensive network of independent solar installers and dealers and significantly increase the ability of NRG to meet the growing demand for high quality residential solar services delivered by a market leader in delivering retail electricity services in the home.

"With the price of residential solar increasingly competitive with the retail price of power in multiple states, the time is now for NRG to ramp up its efforts to bring the benefit of self generation to NRG's millions of present and future retail electricity customers," said David Crane, President and CEO of NRG Energy. "Roof Diagnostics Solar, its management and all of its dedicated employees are a perfect fit with NRG as together we take a big step towards a national residential solar business platform. With residential solar sales expected to take off in the next few years, NRG wants and expects to meet the demand of Americans in every state who are seeking to benefit from the inexhaustible supply of clean energy provided by the sun while affording themselves greater independence from an increasingly less reliable electric grid."

"Backed by the tremendous resources, capabilities and commitment of NRG, Roof Diagnostics can greatly increase the growth we have achieved since starting operations in 2011," said Kelcy Pegler, Jr., Chief Executive Officer of Roof Diagnostics, who will continue to lead RDS for NRG. "We look forward to working closely with the NRG team to advance the work they have done in solar and other innovations to enable greater customer choice in their power."

RDS is one of the largest solar sales and installation companies in America and a market leader in every state they operate. The 475-employee company has experienced tremendous growth in just a few short years in the Northeast and is now expanding into California and other areas.

"Together, the RDS team and NRG's existing extensive network of independent residential solar installers and dealers will allow us to give customers and potential customers significant options in creative and compelling home power systems," said Denise Wilson, President NRG New Businesses. "NRG's expertise to help customers make an informed decision on residential solar just got better as did the confidence customers can have knowing that an experienced Fortune 500 company is behind their solar installation and ensuring it reaches its maximum potential."

RDS' headquarters will remain in Wall Township, New Jersey. Over the next month, the company will begin operating under the brand NRG Residential Solar Solutions.
