The Federal Energy Regulatory Commission on Nov. 6 approved Tesoro Refining & Marketing Co. LLC for market-based rate authority so it can sell power out of two newly-acquired facilities.
On June 28, Tesoro filed the application for market-based rate authority with an accompanying tariff. The proposed market-based rate tariff provides for the sale of energy, capacity, and ancillary services at market-based rates in the Southwest region.
Tesoro recently acquired the Wilmington Coke Calciner qualifying facility (QF), a 35.8-MW cogeneration facility, and the BP Carson Refinery Site QF, an 8-MW cogeneration facility, both located in southern California.
Tesoro is owned by Tesoro Corp., a publicly traded company that owns and operates refineries for the manufacture of various petroleum products, and is affiliated with entities that own or control generation facilities located in North Dakota, Utah, Alaska, and Hawaii. Tesoro and its affiliates own and operate about 547 MW of generating capacity in the Southwest region, all of which is located in the California ISO market.
