TORONTO, ONTARIO--(Marketwired - May 22, 2015) - Capstone Infrastructure Corporation (TSX:CSE)(TSX:CSE.DB.A)(TSX:CSE.PR.A)(TSX:CPW.DB) (the "Corporation") today announced the commissioning of the 25-megawatt Goulais Wind Farm in the Algoma District of Ontario, north of Sault Ste. Marie. The site consists of 11 Siemens S113-2.3-megawatt turbines, has a 20-year Feed-in-Tariff (FIT) contract with the Independent Electricity System Operator (IESO) expiring in 2035 and was developed in partnership with the Batchewana First Nation of Ojibways.

"We're very pleased that Goulais has been commissioned, the third Capstone wind project to successfully achieve commercial operations in the past nine months," said Michael Bernstein, President and Chief Executive Officer. "Our partnership with the Batchewana First Nation of Ojibways has been essential to the successful completion of this project and we are grateful for their valuable contribution to it."

"Clean energy projects such as the Goulais Wind Farm are aligned with our People's expectations around alternative energy sources that are compatible with looking after our mother, the earth," said Batchewana First Nation Chief Dean Sayers. "Our partnership with Capstone is an excellent representation of building economic growth, while respecting the obligations to preserve the land. This initiative will help us guarantee a healthier and cleaner environment for our future generations."

The Goulais Wind Farm is part of a larger development program for Capstone that includes the 9.5-megawatt Skyway 8 and 24-megawatt Saint-Philemon sites, which were commissioned in August 2014 and January 2015, respectively. Capstone also has Renewable Energy Approvals in hand for the Ontario-based Ganaraska, Grey Highlands ZEP, Grey Highlands Clean and Settlers Landing facilities. Construction on the first of these projects is expected to start later in 2015. Approvals are pending for one additional Ontario project, and one in Saskatchewan. In sum, all of these wind projects comprise a development program totalling 86.9 net megawatts.

"Capstone's consistent progress in organic growth demonstrates our ability to execute on our wind development projects, which form an important part of our strategy to create long-term value and stability for our shareholders," said Mr. Bernstein. "I commend our development team for their dedication and hard work in getting Goulais commissioned on budget and within our time frame."
