Vermont Yankee Nuclear Power Station

The Vermont Yankee Nuclear Power Station (Vermont Yankee) is a nominal 650 megawatt boiling water reactor located in the southeastern corner of Vermont, in the town of Vernon. Vermont Yankee is  the largest electric generation station within Vermont. In 2002, Vermont Yankee was sold by the eight New England utilities that owned the plant to Entergy Nuclear Vermont Yankee, LLC, a subsidiary of Entergy Corporation of New Orleans, Louisiana.

Vermont Yankee began operating in 1972 and was licensed to operate for 40 years through March 21, 2012. Vermont Yankee received a renewed operating license from the U.S. Nuclear Regulatory Commission (NRC) extending the plant operation for an additional 20 years to 2032. However, Vermont Yankee must also receive approval from the State of Vermont to operate beyond 2012. Entergy Nuclear Vermont Yankee has petitioned the Vermont Public Service Board for a Certificate of Public Good in Docket 7862, to operate Vermont Yankee for an additional twenty-year period ending in 2032. That case is still pending in front of the Public Service Board, and Vermont Yankee has continued to operate beyond March 21, 2012, while that case is pending.

On August 27, 2013, Entergy announced that Vermont Yankee would cease operations in the fourth quarter of 2014 for economic reasons, and also amended its petition in Docket 7862 to seek approval to operate only through December 31, 2014. On September 23, 2013, Entergy formally notified the NRC that it would cease operations in 2014.

On December 23, 2013, the State of Vermont and Entergy VY announced a Settlement Agreement (the “Agreement”) that resolves all ongoing litigation between the State and Entergy VY, and provides a path to decommissioning and site restoration of Vermont Yankee.  The full text of the Agreement can be read here.  The Agreement is contingent upon the Public Service Board issuing a Certificate of Public Good in Docket 7862 by March 31, 2014.  As part of the Agreement, the State and Entergy VY submitted a Memorandum of Understanding (MOU) to the Public Service Board in Docket 7862.  The full text of the MOU can be read here. A joint statement by the parties to the Agreement can be read here.


Nuclear Issues Vermont Faces

In the present and coming years, Vermont faces a number of issues related to the Entergy Nuclear Vermont Yankee power station (Vermont Yankee) including:

  • The national dilemma of no permanent storage plan for spent nuclear fuel from power reactors.
  • Additional studies are being conducted concerning lessons learned from the problems uncovered at Fukushima, Japan following the tsunami event there.

The Vermont Comprehensive Energy Plan also contains more extensive discussion of these and other nuclear issues.
