Google has asked for approval from the Federal Energy Regulatory Commission to become an electricity marketer, essentially giving it the authority to buy and sell bulk power at market prices, just the way large utilities and energy traders do. Via WSJ.
Google’s power usage is unclear; it doesn’t disclose how many data centers it operates or where each is located. Last April, it said its data centers were the most efficient in the world, so far as it was able to determine, but declined to say how much power it actually uses.
Rich Miller, editor of Data Center Knowledge, an online publication that tracks the data center industry, says he has identified about 24 Google data centers. He says it is common for large centers run by Internet companies to consume 30 to 50 megawatts of energy capacity.
Google’s largest data centers could use even more. A data center consuming 10 megawatts is about what a subdivision of single-family homes consumes. Based on an estimate of 24 large data centers, Google’s energy need would be roughly equivalent to the output of two large conventional power plants.
In 2007, Google announced its intention to become “carbon neutral,” meaning it would take actions to neutralize the effects of carbon dioxide produced in the course of furnishing its buildings and data centers with electricity. It installed a 1.6-megawatt solar array on its headquarters building and has been trying to obtain green power, when available.
If its FERC request is granted, “we could go directly to a renewable energy project and buy power for our operations,” says Google spokeswoman Niki Fenwick. The company also wants the ability to enter into contracts for carbon offsets.
Google’s FERC application could also potentially allow the company to play a much larger role in energy markets, even becoming a wholesaler of electricity to other big buyers.
In its application, the company said it was reserving for itself the right to “act as a power marketer, purchasing electricity and reselling it to wholesale customers,” and trading “in the bulk power markets, such as arranging…transmission and fuel supplies.”
