TVA takes enviro input on 10-MW and 20-MW solar projects

The Tennessee Valley Authority said May 12 that it is seeking public comments on draft Environmental Assessments for two proposed power purchase agreements with solar generating facilities.

TVA has tentatively approved 20-year agreements to purchase 30 MW in total, pending the outcome of the assessments.

  • Coronal Development Services is proposing the 20-MW (dc) Latitude Solar Center near Whiteville, Tennessee, in Hardeman County. The 135-acre solar facility would connect to the TVA transmission system through a power line to an existing Bolivar Electric Authority substation.
  • Silicon Ranch Corp. is proposing the 10-MW (dc) Selmer North II Solar Project in McNairy County, Tenn. The facility would occupy about 73 acres near Selmer and tie to the TVA transmission system through a connection to a nearby Pickwick Electric Cooperative power line.

Both facilities would consist of multiple rows of single-axis tilt photovoltaic panels to generate electricity. The draft Environmental Assessments evaluate the anticipated environmental impacts of the construction and operation of the solar generating facilities and associated electrical connections.

Comments for the Latitude project should be submitted by June 6. Comments for the Selmer project should be submitted by June 13.

In its 2011 Integrated Resource Plan (IRP), TVA established the goal of increasing its renewable energy generating capacity by 1,500 to 2,500 MW by 2020. TVA established the Renewable Standard Offer (RSO) program as one of the means of meeting this goal. Under the RSO program, TVA purchases energy at established terms and conditions (the “standard offer”) from operators of qualifying renewable energy-generating facilities. Qualifying facilities must be new, located within the TVA service area, and must generate electricity from specific technologies or fuels. Solar PV generation is one of the qualifying technologies.

TVA’s 2015 IRP recommends the continued expansion of renewable energy-generating capacity, including the addition of between 175 and 800 MW of solar capacity within its jurisdiction by 2023. The proposed actions would help meet this need for additional solar capacity.
