101.2 MW Hatchet Ridge Wind Farm to Generate Power for Nearly 44,000 California Homes Annually

SAN FRANCISCO, Oct. 8 /PRNewswire/ -- Pattern Energy Group LP (Pattern) today announced the closing of financing and commencement of construction of its Hatchet Ridge wind project, the first large-scale wind project to begin construction this year in California. The 101.2-MW Hatchet Ridge project, developed by Renewable Energy Systems Americas Inc. (RES Americas), will be located on a portion of Hatchet Mountain near the town of Burney in Shasta County, California. The project is expected to finish construction and reach commercial operation before the end of next year.

Hatchet Ridge will generate power equivalent to the amount of energy needed to serve nearly 44,000 California homes annually. Pacific Gas and Electric Company (PG&E) will purchase the power, including the renewable attributes, under a 15-year power purchase agreement.

In addition to providing clean, renewable energy for Californians, Hatchet Ridge will create approximately 100 - 200 construction jobs over the next year and 6 - 8 permanent jobs during operations. There will also be an economic ripple effect in the area from the purchases of goods and services for the wind farm and increased business for service industries.

Hatchet Ridge will invest $5 million dollars in the local community over the life of the project through the Shasta County General Fund, the Shasta Regional Community Foundation, and the Burney Foundation Regional Education Fund as well as pay substantial local taxes.

Pattern selected a six-bank club to provide a debt facility to fund project costs during construction, which converts to a term financing facility upon commercial operation. The lenders include: Natixis, UBOC, LBBW, Calyon, SocGen, and WestLB. RES America Construction, Inc. will construct the project, which will consist of 44 Siemens 2.3 MW turbines. The Siemens SWT-2.3-93 wind turbine is a proven technology with more than 2,000 operating worldwide and is well-regarded throughout the industry.

"We are pleased to close financing and commence construction on the Hatchet Ridge Wind Farm. We are very excited about starting construction of our first project only four months after forming Pattern Energy," said Mike Garland, CEO of Pattern Energy. "This project is the result of years of dedication and collaboration with RES Americas, Siemens, PG&E, local government, project property-owners, and the community. We are very appreciative for the local support we received that helped make this project a reality."

"California is one of the top states in generating wind power capacity and we are excited to continue to bring clean, renewable energy to the region and working with the local businesses in completing the project," said Andrew Fowler, Senior Vice President of Construction of RES Americas. "Renewable energy brings economic benefits to the community and provides a secure and sustainable future for all."
