tried to eliminate a fundamental solar policy, net metering, at the LPSC several times, and failed each time. SWEPCO also backed openly anti-solar candidate Eric Skrmetta, who has been widely criticized for receiving 2/3 of his campaign contributions from entities he regulates. In Arkansas, SWEPCO is expected in 2015 to ask regulators to allow them to pass along the costs of building and running the John W. Turk Jr. Coal Plant, the most expensive project in state history, to Arkansas ratepayers. This process is expected to elicit similar controversy to what has plagued the plant since construction. SWEPCO operated Dolet Hills Power Station was scheduled for closure in Louisiana in 2021, due to pressure by Beyond Coal. Other subsidiaries AEP also bought much of the town of Cheshire, Ohio, where the Gavin Power Plant is located, due to pollution issues. In 2004, AEP announced their plans to build one, or more, integrated gasification combined cycle (IGCC) coal-fired power plant which is expected to reduce emissions while providing additional electricity capacity to the customers served by AEP. The company also operates its own inland barge line, AEP River Operations (formerly MEMCO Barge Line), and owns major tracts of land throughout its service areas. In August 2008, AEP has formed a joint venture company with Duke Energy to build and own new electric transmission assets. It is the largest shareholder in the Ohio Valley Electric Corporation (OVEC). OVEC is an associate company of AEP, not a subsidiary, because AEP owns less than half of it. Nuclear AEP owns and operates the Donald C. Cook nuclear power plant. This accounts for 6% of the generation portfolio. Hybrid technology AEP is expanding its green efforts to include 18 more International DuraStar hybrid diesel trucks. AEP is also teaming with Ford for the integration of a Vehicle-To-Power grid communication system, which allows hybrid vehicles to communicate with power companies to determine where, how long, and what it would cost to re-charge a hybrid during travel. Solar and wind energy In 2009, AEP signed a deal with Wyandot Solar LLC to purchase power from one of the largest solar fields in the eastern United States of America, based in Upper Sandusky, Ohio. AEP owns and operates the Desert Sky Wind Farm and the Trent Wind Farm. In 2009, AEP partnered with other energy companies in commissioning a study of how to transmit wind energy generated in
