A physics argument broke out at Friday's hearing on the Bluewater Wind contract. When a wind farm powers up, which plants power down? Bluewater Wind officials said Friday that in the congested Delmarva Peninsula, it will be area fossil-fuel plants. Area residents will realize a direct environmental and health benefit, they said. But Delmarva Power officials said the benefits will be diluted throughout the 13-state PJM electrical grid, and would have its biggest impact on oil-burning plants, not generators that use the notoriously dirty-burning coal. ...Citing a PJM Interconnection official who spoke at the hearings, they contended environmental benefits of an offshore wind farm would be spread throughout the grid. It wouldn't be coal that would go first, but more-expensive fossil fuels such as oil, said company spokesman Bill Yingling.

Because wind-driven electrical generators would be located in the ocean, the corrosion effects will result in more down time and higher maintenance costs ...
The manufacturer picked to supply a proposed Delaware wind farm has halted production of its offshore turbine because of a faulty component. ...Of Vestas' 96 V-90 turbines installed off the coast of Europe, between 10 and 15 are idle as workers fix the gears, said Anders Soe-Jensen, president of Vestas Offshore. All of the gearboxes will eventually have to be replaced, if they haven't been already. ...Delmarva Power spokesman Bill Yingling said his company is disappointed Bluewater Wind didn't alert Delmarva to the mechanical problem during negotiations for a power purchase agreement. ..."It [offshore wind] will grow far bigger, but we do not believe, in the foreseeable future, it will become as big as people believe. Media coverage for offshore far exceeds reality," Kruse said. There are about 15,000 megawatts of wind power available globally, but only about 198 of those megawatts come from offshore production, he noted.
In an effort to secure a lucrative deal to supply Delmarva Power with electricity, three power companies are calling their rivals’ technology risky and potentially harmful to the environment, according to documents obtained by The News Journal. The conflict highlights two innovative but domestically unproven technologies. NRG Energy wants to add a coal gasification facility, perhaps with new environmental safeguards, to its Indian River plant. Bluewater Wind hopes to put up a wind farm in the Atlantic Ocean off the Delaware coast............Bluewater Wind. marked as “confidential” large portions of its filing, including information on electrical capacity. NRG has raised questions about the wind company’s ability to provide electricity during the hottest summer days. But Bluewater Wind removed details about its projected seasonal capacity from its filing.
