Danbury-based FuelCell Energy is planning to furlough some workers at its Torrington plant this summer.  The shortened work weeks will affect 110 employees.  FuelCell is taking part in the state's “Shared Work Program” which is for companies thinking about laying off a minimum of 10-percent of their workforce.  Employees will be able to collect half unemployment benefits during the furlough and can seek employment elsewhere, while remaining on FuelCel's health plans.  Company officials said in an investor conference call that this could change if state legislation is singed authorizing the purchase of up to 100 megawatts of new generation capacity from renewable sources, including fuel cells.
