The Federal Energy Regulatory Commission has authorized Google Energy to buy and sell electricity in bulk like any other utility.

The FERC, the agency with oversight of the U.S. power grid, signed an order (PDF) on Thursday that grants Google Energy market-based rate authorization. This paves the way for the search giant to not only better manage its own energy costs, but to possibly add electricity marketer to its repertoire of services.

The order specifically grants Google Energy--a subsidiary of Google--the rights "for the sale of energy, capacity, and ancillary services at market-based rates" while acknowledging that neither Google Energy nor its affiliates "own or control any generation or transmission" facilities.
