FERC grants approvals for Patua’s 90-MW geothermal project

The Federal Energy Regulatory Commission on June 24 granted certain waivers to Patua Project LLC related to its 90-MW geothermal project in Nevada.

Patua Project had asked for waivers of certain requirements under Order Nos. 888, 889, and 890, and Part 358 of the commission’s regulations. Patua is a wholly-owned subsidiary
 of Gradient Resources LLC. Patua will own and operate an approximately 90 MW geothermal facility currently under construction, with the facilities spanning Churchill and Lyons counties, Nev.

On May 6, Patua told FERC that it will also own and operate limited, radial generator interconnection facilities, including a dedicated 8-mile, 120-kV gen-tie line that will interconnect the project to the integrated transmission system in order to deliver the power to Sierra Pacific Power’s transmission system. Patua explained that the line will be constructed for its sole use and exclusively for the purpose of delivering output from its project to the integrated transmission system.

On May 6, 2013, requested waiver of the following commission regulatory requirements applicable to transmission providers: the Open Access Transmission Tariff (OATT), the Open-Access Same-Time Information System (OASIS), and the Standards of Conduct, in connection with an application for market based rate authority. Specifically, Patua requested waiver of the requirements of Order Nos. 888, 889, and 890 and Part 358 of the commission’s regulations. Patua asserted that the interconnection facilities are radial, sole-use interconnection facilities dedicated exclusively to the generation owner’s facility. Patua claimed that the interconnection facilities are limited and discrete, not an integrated component of any transmission grid, and designed solely to enable Patua to transmit electrical energy from its project to the point of interconnection with the integrated transmission system.

Patua has told FERC it is developing the project in 30 MW (net) phases, each of which is fully committed from its respective commercial operation date under a long-term power purchase agreement (PPA) with a non-affiliate, the Sacramento Municipal Utility District (SMUD). The project will interconnect to the Sierra Pacific Power system via the Eagle Substation located within the limits of the City of Fernley, Nev.
