Saranac Lake is considering a plan that would allow it to start up a geothermal heating and cooling utility, in theory, without paying a dollar for the massive project. According to the Adirondack Daily Enterprise, a set of circumstances are lining up to make this a possibility — state grants, a contract with a multinational conglomerate and the Adirondack Park Agency’s plan to relocate its headquarters to downtown Saranac Lake. The village board is set to discuss this again at its meeting on Tuesday evening.
