Portland General Electric (PGE) has signed a deal with Renewable Energy Systems Americas (RES Americas) to buy the development rights for the Rock Creek Wind Farm in Oregon, US.
The company said new generating resources will be needed to meet Oregon's renewable energy standards in future.
PGE has also filed a waiver request with the Oregon Public Utility Commission (OPUC) on the commission's bidding guidelines with regards to the project.
The terms of the preliminary agreement are expected to remain confidential until the parties sign a definitive agreement and satisfy related conditions.
RES Americas is currently pursuing state permits for the proposed facility with a 400 to 550MW of energy production capacity, depending on the size and number of turbines.
The company expects construction to begin by 2013, but will occur in phases in 2014 or 2015.
