SunEdison and Gamesa sign memorandum of understanding to create a 50/50 joint venture to develop up to 1 gigawatt of wind power plants globally by 2018 --- Gamesa to supply the wind turbines and assume responsibility for the long term operation and maintenance of the wind power plants --- SunEdison to acquire the projects upon the start of construction and once operational, to drop the projects into TerraForm

MARYLAND HEIGHTS, Mo. and MADRID, July 2, 2015 -- SunEdison, Inc. (NYSE: SUNE), the world's largest renewable energy development company, and Gamesa (BME: GAM), a global technology leader in wind energy, today announced that they have signed a Memorandum of Understanding (MoU) to create a joint venture to develop up to 1 gigawatt (GW) of wind energy power plants globally by 2018. SunEdison and Gamesa will each own a 50 percent stake in the joint venture.

Under the terms of the agreement, Gamesa will supply the wind turbines and be responsible for operation and maintenance (O&M) of the wind power plants as part of long term O&M agreements. Gamesa may also provide engineering, procurement, and construction services for the projects. Ownership of the projects will be shared during development; upon construction SunEdison will acquire the projects from the joint venture. SunEdison will purchase additional wind turbines from Gamesa, based upon development volume targets achieved by the joint venture.

"This agreement will accelerate SunEdison's drive to respond to rapid growth in global wind markets," said Paul Gaynor, SunEdison executive vice president of the Americas and EMEA. "By partnering with Gamesa, one of the world's leading wind technology and development companies, we're particularly well positioned to capture the opportunity in India and Mexico, two regions where we already have a strong solar presence."

"This strengthens our position in the global wind energy market," said Carlos Domenech, president and chief executive officer of TerraForm Power. "This joint venture reinforces our commitment to emerging markets."

"This alliance with SunEdison falls under the umbrella of our new Technology Development Programme, within the 2015-2017 Business Plan, and will enable Gamesa to make the most of its technical and management experience, further reinforcing our position as a leading developer. The combination of both companies' strengths would also unlock synergies and maximise project returns," said Xabier Etxeberria, Gamesa's chief executive officer.

"This agreement evidences Gamesa's ability to come up with flexible collaboration and joint investment alternatives with very limited funding requirements," underscored David Mesonero, Gamesa managing director of corporate development.

SunEdison intends to place the power plants acquired from the joint venture on the call rights list for TerraForm Power. It is expected that the definitive agreement, including the initial selection of projects for development from Gamesa's pipeline, will be signed by the end of 2015.
