Wind turbines in the Bonneville Power Administration's transmission grid generated more than 3,000 megawatts for the first time this week, producing enough electricity to serve a city three times the size of Seattle.
The growth of Northwest wind power continues to exceed expectations of just a few short years ago, said a Bonneville Power Administration news release.
More than 1,500 megawatts have been added in the last two years.
Even though most of the Northwest's wind power is owned by private developers, they rely on BPA's extensive transmission grid to move that power.
The Portland-based BPA owns and operates three-quarters of the Northwest's high-voltage transmission.
The number of wind generation sites contributing to this record now total 35. The wind farms include more than 2,100 turbines found mostly east of the Columbia River Gorge.
BPA is a not-for-profit federal electric utility that operates a high-voltage transmission grid and markets more than a third of the electricity consumed in the Northwest.
BPA power is produced at 31 federal dams and the nuclear plant near Richland. And it buys power from seven wind projects and has more than 3,300 megawatts of wind interconnected to its transmission system.
