Northern New England's hydro dams are struggling to generate power because of drought conditions. Regional Grid operator ISO-New England spokesperson Mary Kate Colapietro said environmental conditions can affect electricity production. "That could be a variety of factors, from things like the weather, if there are say drought conditions that could perhaps impact what generators are making decisions on," Colapietro said. But there might be other reasons dam owners could also be holding back from bidding to sell energy into the grid, Colapietro added.
