OMERS Infrastructure Management Inc. on March 22 said it has agreed to purchase ArcLight Capital Partners LLC's Dallas-based wind portfolio company with a total installed capacity of about 1,700 MW for an undisclosed sum.

Leeward Renewable Energy LLC develops, owns and operates 19 wind projects across nine states, including California, Colorado, Idaho, Illinois, Oklahoma, Pennsylvania, New Jersey, New Mexico and Texas, according to a company news release. The output of most of the operating wind facilities is committed to specific buyers.

Subject to customary approvals, the companies expect to close the deal during the third quarter of 2018.

"Upon closing of the transaction, we believe Leeward's partnership with OMERS Infrastructure will only enhance the company's role in the renewable energy future of the U.S. power markets," ArcLight founder and managing partner Dan Revers said.

OMERS Infrastructure is an investment arm of the Ontario Municipal Employees Retirement System, a defined benefit pension fund for Ontario government employees.

Wells Fargo Securities LLC is serving as exclusive financial adviser to OMERS Infrastructure, while Shearman & Sterling LLP is its legal counsel. Bank of America Merrill Lynch is acting as exclusive financial adviser to Leeward Renewable, while Latham & Watkins LLP is acting as legal adviser.
