Rule Issued on Connecting Generators to Transmission Grid

LCG, July 23, 2003--The Federal Energy Regulatory Commission intends to minimize the effort spent on negotiations between transmission providers and generators, with the issuance of a final rule specifying what costs are to be paid by either party when a generator with capacity of at least 20 megawatts is connected to the transmission system.

A generator owner connecting to transmission operated by a company that is not independent will need to pay for costs on the generation side of the transmission infrastructure. Upgrades to the transmission side during the would also be paid by the generator owner, although the payments could be refunded by the transmission provider.

Existing interconnection agreements will be maintained as they are currently. Regional transmission organizations will have some flexibility, and could engage in what is called participant funding for the first year of the rule being issued. A rule covering generators below 20 megawatts will be issued shortly, FERC has said.
