On Feb. 8, EFSEC received an application for a site certification from Horse Heaven Wind Farm, LLC proposing the construction and operation of the Horse Heaven Wind Farm project in Benton County. The applicant proposes the construction of a renewable energy generation facility that combines wind and solar facilities, and battery energy storage systems, with an energy generating capacity of up to 1,150 megawatts. The applicant proposes that if approved, commercial operation of the first phase built would begin by the end of 2023. 

The applicant is requesting permitting authorization for up to 244 turbine locations and two solar arrays to convert energy from the wind and sun into electric power and then deliver that power to the electric power grid. 

The applicant has also requested a review under expedited processing, which EFSEC can grant if the environmental impacts are not significant or can be mitigated to non-significant levels, and the project is consistent and in compliance with city, county, or regional land use plans. EFSEC has 120 days to determine whether or not the application qualifies for expedited review. 

EFSEC is the state agency charged with providing one-stop permitting for certain types of major energy projects in Washington. EFSEC specifies the conditions of construction and operation. The council also manages an environmental and safety oversight program of facility and site operations. 

EFSEC is an independent council that is administratively housed at the Washington Utilities and Transportation Commission.
