Economic Analysis about Big Consumers Purchasing Electricity Directly

Abstract:

If the big users electricity consumption kept the same, while comparing through grid direct-purchasing power with building the power plant and purchasing the power by grid, and then establish the profit and loss model and point to point mode. Finally, we need to demonstrate the economy of direct power purchase through the example and value.
