NRG Yield, Inc. To Acquire Energy Systems Company

  — Leading Thermal Infrastructure Assets Significantly Increases Cash Available for Distribution —

PRINCETON, NJ; December 3, 2013 — NRG Yield, Inc. (NYSE: NYLD), in its first third-party acquisition, has entered into an agreement to acquire the assets of privately held Energy Systems Company (ESC) of Omaha, Neb., an award-winning supplier of district energy, for $120 million in cash.

NRG Yield intends to fund the purchase price using cash on hand and expects the acquisition to increase Cash Available for Distribution by approximately $8 million in 2014. The assets will be acquired debt-free.

“The acquisition of ESC demonstrates NRG Yield’s ability to successfully compete for attractive contracted energy assets available from third parties,” said David Crane, NRG Yield’s Chairman and Chief Executive Officer. “In addition to contributing to our objective of sustainable and visible dividend growth for our investors, ESC provides us another important opportunity to supply the energy needs of business and other institutional customers directly and in a manner that is not entirely grid dependent.”

ESC currently serves nearly 14 million square feet of data center, commercial, educational, hospital, cultural and governmental space in Omaha with a weighted average remaining life of customer contracts over 11 years. The Omaha system to be acquired by NRG Yield is known as one of the premier assets in the U.S. district energy industry and has been recognized as a “System of the Year” by the International District Energy Association (IDEA) — one of only 15 such systems (out of more than 700 in the U.S. alone) that has received this award.

“As just the second owner in ESC’s 45-year history, we have long been committed to providing reliable district energy service to our many customers in downtown Omaha,” says Todd Johnson, ESC’s Chairman and CEO. “So it was important to us that the new owner be a stable, well-respected company like NRG that would honor that tradition of operational excellence. We are confident that it is an exceptional fit for both parties.”

Investment Highlights:

·                  Immediately accretive to 2014 Cash Flow Available for Distribution per share by approximately 8%

·                  Consistent with NRG Yield strategy of acquiring long-term contracted assets that favorably complement its existing portfolio and offer long-term growth opportunities

·                  Unique opportunity to achieve geographic diversification and grow thermal infrastructure platform

·                  Demonstrates NRG Yield ability to execute on its growth strategy through third-party acquisitions

NRG Yield expects the transaction to close by the end of the year.
