In June 2014 GDF Suez said the plant, which has been in operation since 1960, will close in October 2014 after more than three years of on-and-off operation. GDF Suez spokesperson Carol Churchill said the Holyoke plant cannot compete with cheaper natural gas, and confirmed that the company will consider converting the plant to producing electricity from solar energy. In 2013 legislation enabled the state’s Clean Energy Center to allot $100,000 to Holyoke to work on shaping plans for reuse of the Mount Tom site in the event of its closing. GDF Suez had earlier sought approval to halt power production in 2016-17.[1]
