On January 21, 2010, the Federal Energy Regulatory Commission (“FERC”) invited industry comments on possible changes to its rules that might be needed to better accommodate VERs. For purposes of the inquiry, FERC defined a VER as renewable energy resources with variable fuel sources that they cannot control, including wind and solar generator and certain hydro resources. FERC is concerned that many of its transmission and electricity market policies were developed with conventional generation in mind and may need to be revisited to support the integration of large amounts of new VER capacity into the system. Thousands of pages of comments were submitted, many calling for a variety of changes and improvements. Further FERC action is likely.
