Horse Heaven Wind Project

Project background:

On February 8, 2021 EFSEC received an Application for a Site Certification (ASC) from Horse Heaven Wind Farm, LLC proposing the construction and operation of the Horse Heaven Wind Farm project. The ASC proposes the construction of a renewable energy generation facility that would have a nameplate energy generating capacity of up to 1,150 megawatts (MWs) for a combination of wind and solar facilities as well as battery energy storage systems (BESS). The proposed project is located in Benton County, Washington. According to the ASC, if approved, the Applicant is anticipating commercial operation of the first Phase to be built by the end of calendar year (CY) 2023.

The Applicant is seeking permitting authorization for up to 244 turbine locations and two solar arrays with their capacity dependent on the approved location, technology, and power market interest.

The Facility will utilize wind turbines and solar photovoltaic (PV) panels to convert energy from the wind and sun into electric power which is then delivered to the electric power grid. Two battery energy storage systems are proposed that would have a storage capacity of up to 300 MWac (megawatt capacity) using lithium-ion batteries.
