This is true. About 85% of our power comes from Niagara Falls and is purchased at a fixed rate. However, the cost associated with getting that energy to us fluctuates with demand and the paths available, the term congestion charges is used to account for this. To get power from Niagara Falls to Freeport we use lines owned by LIPA, CON ED, NYPA, NYSEG, Niagara Mohawk, Orange and Rockland, Central Hudson and many others. Each one gets paid based on how much power is transferred.
