Also in 2004 CVPS created its Cow Power program where customers opt in to pay a premium of $.04/kilowatt hour (kWh) on renewably-produced power. In turn, CVPS (renamed Green Mountain Power after merging with that utility in 2012) pays farms a premium of $.04 for each kWh they deliver to the grid. In 2006, Entergy Nuclear Vermont Yankee, LLC requested permission from the utility regulating body, Vermont Public Service Board (PSB) to increase power output from the nuclear plant and to store high-level radioactive waste on-site. The PBS agreed to the request but required Entergy to fund a renewable energy development program. This funding — administered through a "Clean Energy Development Fund" (CEDF) created by the state legislature — could be used "to increase the development and deployment of cost effective and environmentally sustainable electric power sources."
