TVA issues enviro review on 20-MW Wildberry Solar project in Tennessee

The Tennessee Valley Authority is taking comment until March 14 on a draft environmental assessment (EA) covering the 20-MW (dc) Wildberry Solar Center project, planned by Coronal Development Services LLC for a site in Tennessee. 

TVA proposes to execute a power purchase agreement (PPA) with Wildberry Solar Center LLC (WSC), an affiliate of Coronal Development Services LLC, for electricity generated by the proposed 20-MW (dc) solar photovoltaic (PV) facility near the City of Moscow, Tennessee. The proposed solar farm would occupy up to 135 acres of a 347-acre site that WSC would lease for a 20-year period with five-year extension options from the single private property owner.

The facility would be interconnected to the Chickasaw Electric Cooperative (CEC) distribution grid at an interconnection point located on the solar facility site. The existing 2.2-mile long CEC distribution line that runs west along Tennessee Highway 57 from the site to CEC’s Moscow Substation would be upgraded to accommodate the electricity that would be generated by the facility.

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 (referred to as the “standard offer”) from operators of qualifying renewable energy facilities. Qualifying facilities must be new, located within the TVA service area, and must generate electricity from specific technologies or fuels. Solar PV is one of the qualifying technologies. WSC has met the qualifications for the RSO program, and now TVA must decide whether to execute the PPA.

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 by 2023. This proposed action would help meet this need for additional solar capacity.

TVA lately has also been reviewing PPAs with another solar project 

Notable is that TVA was taking comment until Feb. 15 on its draft EA covering two proposed power purchase agreements with a solar facility to be built in Greene County, Tennessee.

TVA has tentatively approved agreements to purchase the electricity generated by Birdseye Renewable Energy’s proposed 20-MW (dc) Brown Swiss solar farm for up to 20 years, pending the outcome of the assessment process. The photovoltaic solar facility, currently scheduled for completion in late 2016, would consist of two adjacent 10-MW (dc) facilities occupying about 130 acres near Chuckey Pike about eight miles east of Greeneville.

The PPAs would be with Brown Swiss Holdings LLC, a subsidiary of Birdseye Renewable Energy. The PPAs would be executed through TVA’s RSO, under which TVA agrees to purchase qualifying renewable energy at set prices for a 20-year period.
