The “Atlantic Wind Connection” (as it’s called) is interesting on several levels. The ownership is split between Google (37.5%), an investment company called Good Energies (37.5%), and the Japan trading company Marubeni (15%). The deal came about from a chance meeting between developer Trans-Elect Development and Good’s desire to find new projects to invest in.
The announcement is interesting on many different levels.
One is that this is a sizable bet among a series of ongoing RE investments by Google. It appears that it fits nicely with the founders’ philosophical support for renewable energy, as announced by Larry Page three years ago (and reflected in their personal investments in Tesla among other cleantech startups.) The announcement also reflects Google’s strengths at mass communications in web-enabled world, as much of the press coverage was just a paraphrase of the key details provided by Google and its partners in its posting and press conference. (A rare exception was the National Geographic story.)
The second point is that, as the Heritage Foundation noted, this is a rare example of a large RE project being funded by private investors rather than hefty government subsidies. They quote approvingly from the official announcement by Google’s “Green Business Operations Director”:
We believe in investing in projects that make good business sense and further the development of renewable energy. We’re willing to take calculated risks on early stage ideas and projects that can have dramatic impacts while offering attractive returns. This willingness to be ahead of the industry and invest in large scale innovative projects is core to our success as a company.transmission infrastructure for any large-scale renewable energy projects: where the power is generated (wind coastal shelves, sunny deserts) is not where it needs to be consumed. The 350 mile transmission line would be built about 22 miles offshore, and come ashore in four places: Northern NJ, Southern NJ, Delaware and Southern Virginia. It would eventually have a capacity of 6 gigawatts of power. The project construction would take from 2013-2021.
Fourth, as an April paper in the Proceedings of the National Academy of Sciences points out, a wide geographic dispersion of wind farms can ameliorate one of the biggest disadvantages of wind power — dramatic fluctuations in output — by smoothing that output over a broader geographic base. The law of averages may make large scale wind generation more useful than the existing wind farms concentrated in a few localized areas like the Tehachapis and the Altamont Pass.
Fifth, the unique advantages of the Mid-Atlantic region point out the limitations of offshore wind more broadly. As the NYT article summarized:
The lure of Atlantic wind is very strong. The Atlantic Ocean is relatively shallow even tens of miles from shore, unlike the Pacific, where the sea floor drops away steeply. Construction is also difficult on the Great Lakes because their waters are deep and they freeze, raising the prospect of moving ice sheets that could damage a tower.So if the plants have to be located far enough offshore to avoid objections over aesthetics but in shallow enough water to operate a fixed platform, there are limited opportunities to do so.
Sixth, it appears that local and state governments have conflicting motives between NIMBYism and a desire for local jobs — to the point of discouraging East Coast use of renewable energy generated in the Midwest. (A similar dynamic has occurred here in California). Again the NYT captured it nicely:
Nearly all of the East Coast governors, Republican and Democratic, have spoken enthusiastically about coastal wind and have fought proposals for transmission lines from the other likely wind source, the Great Plains.Finally, the construction of a transmission line does nothing to solve the daunting cost problems of offshore wind energy. Parochial governors aside, the cost of building and operating wind turbines in the ocean is higher than on flat dry ground: 50% higher is the estimate provided by the NYT.
“From Massachusetts down to Virginia, the governors have signed appeals to the Senate not to do anything that would lead to a high-voltage grid that would blanket the country and bring in wind from the Dakotas,” said James J. Hoecker, a former chairman of the Federal Energy Regulatory Commission, who now is part of a nonprofit group that represents transmission owners.
More generally, the prices of wind generation are not falling as quickly as solar, and in fact ticked up last year at the height of a deep recession. (What’s up with that?) Blogger Tom Fuller argues that wind has a fundamental problem of lack of competition — where a cartel of a few large manufacturers controls the supply of generating equipment — and predicts an eventual triumph for solar:
There are a lot more [solar] manufacturers, and they are increasing capacity continuously. Each new generation of fab provides 20% performance gains, and the next generation of wafers is longer, wider, thinner and less likely to break. Innovations for their balance of system peripherals come from a variety of outside companies in their supply chain, and the inexorable march to grid parity is nearing its goal.So perhaps offshore wind will be the only local supply of RE available to the Northeast, but — as with everything else over the past 40-50 years — the region will remain an expensive place to live and work. In other words, not a good place to put a Google server farm.
They both get the same level of subsidies, which amount to a pittance overall. So what’s the difference?
Solar sells to consumers, too. Residential, small business, offices and plants. Solar scales down as well as up. And their customers are you and me–cranky and demanding if things don’t work, unwilling to sign long term contracts, wanting to see bottom line improvements rather than brochures showing acres of installations.
So solar will win. Not because they’re nicer guys, but because their industry is more fragmented and they have more demanding customers.
Which, I believe, is the way the system is supposed to work.
