We have our own village electric service with a fixed rate contract for hydroelectric. When we go over the 100,000 kw limit we pay extra for purchasing power from the grid, which I'm told, is supplied by mostly gas-fired power plants.
In summer it's 3.5 cents a kw, total cost delivered. In winter that usually goes up to 4.5 - 5.5 cents kw because of the added cost for going over the village's limit.
This winter we're way over that limit. The high demand has driven the cost up to 9.5 cents kw. More than half of which is purchased power.
Not as bad as the 16 cents kw I had 22 years ago on Long Island, but it's still a shock to see bills almost double what they usually are.
So much for the BS that all those windmills around here will bring electric costs down.
