Shepherds Flat Central is a wind energy facility with 116 turbines and a maximum generating capacity of 290 megawatts, located within a site boundary of approximately 11,769 acres.
Under Review/Operating. On October 25, 2019, the Council approved a second amended site certificate, authorizing the certificate holder to lower the minimum above ground blade tip clearance for two wind turbines from 25 to 21.5 meters based on proposed operations and maintenance demonstration activity that would replace wind turbine blades and modify nacelles.

On October 7, 2019, the Department received a Request for Amendment 3 to the Shepherds Flat Central site certificate (RFA3). RFA3 seeks approval for wind turbine upgrades that would include replacing the wind turbine blades and modifications to the nacelles. The upgrades would require Condition 26 to be amended, lowering the minimum aboveground wind turbine blade tip clearance from 25 to 21.5 meters for 114 of the 116 turbines (two turbines, T-368 and T-370, were assessed as part of Request for Amendment 2). On December 31, 2019, the Department received the complete Request for Amendment 3 to the Shepherds Flat Central site certificate.

On December 31, 2019, the Department issued a Draft Proposed Order on RFA3. The Department is now seeking written comments on RFA3 and the Draft Proposed Order.

Written comments on RFA3 and the Draft Proposed Order on RFA3 must be received by 5:00 p.m. PST on January 20, 2020, and must be submitted in writing by mail, email, hand-delivery or fax per below:
