Ormat’s Wild Rose geothermal project due in service in October

ORNI 47 LLC, a unit of Ormat Technologies, on Aug. 2 asked the Federal Energy Regulatory Commission for various approvals related to its in-development Wild Rose geothermal power project.

It asked the commission to: accept the attached market-based rate tariff under which ORNI 47 will sell electric energy, capacity, and ancillary services at market-based rates; designate ORNI 47 as a Category 1 seller in all regions; grant other waivers and blanket authorizations generally granted to wholesale sellers; grant a waiver of requirement set forth in Order Nos. 8881, 8892, and 8903; and waive prior notice requirements in order to permit the requested authorizations and waivers to become effective as of Oct. 1, 2013.

ORNI 47 is a wholly-owned indirect subsidiary of Ormat Technologies, a publicly-traded company. Ormat is the only vertically-integrated company primarily engaged in the geothermal and recovered energy power business.

ORNI 47 was formed by Ormat for the sole and exclusive purpose of constructing, owning, and operating the Wild Rose Geothermal Project near Gabbs, Nev. Wild Rose is scheduled to be placed into service in October. It is located within the balancing authority area of Sierra Pacific Power and will interconnect to transmission facilities owned and operated by Sierra Pacific.

“Wild Rose will operate as a variable energy resource,” the application noted. “As such, the nameplate capacity of Wild Rose (25 MVA) does not reflect the actual net capacity after Wild Rose supplies its own Station Power and Fuel Delivery System. In addition, net generation varies over time depending primarily on ambient weather conditions. Due to the factors mentioned above, the expected yearly average net capacity of Wild Rose is 16-17 MW and the maximum net capacity of Wild Rose in extreme cold weather is estimated to be approximately 22 MW.”

Other than Wild Rose, ORNI 47 does not own or control any other electric generation facilities in the U.S. Other than the interconnection facilities that will connect Wild Rose to the Sierra Pacific transmission system – a 20.5-mile, 120-kV tie line – ORNI 47 does not own, operate, or control any transmission facilities in the U.S.
