As this article in Yesterday's Oregonian notes:
Windmills and power lines operate near Wasco in Sherman County. The region's electricity grid will need to expand to handle all the new wind and other renewable energy projects being built across Oregon and the West.
------------
The rows of white turbines spinning over wheat fields and ridgelines in eastern Oregon are ample evidence that renewable energy from wind is real and growing. So much so that the aging network of transmission lines and power stations that carries energy around the region is loaded to its limits.
But wind developers are just getting started. And thousands of miles of new power lines carried by skyscraper-sized steel towers will need to be laid across deserts, farms and forests as more wind farms rise in farther-flung corners of Oregon and the West. It won't be cheap, or without controversy.
More than half of Oregon is public land that Oregonians value for recreation, unobstructed vistas and habitat for sensitive species. And the cleared corridors that accommodate such transmission lines cut a wide swath. Expanding the power grid is one trade-off of the national effort to expand clean energy technology and combat climate change.
"There's no question that we are changing the face of the state right now," said Brent Fenty, executive director of the Oregon Natural Desert Association in Bend, which is tracking transmission proposals in eastern Oregon. "And the important part is that we do that in a way that is responsible and reflects our values."
Energy experts have long lamented the inadequacy of the nation's energy grid. The federal government estimates that even though electricity demand has increased nationally by a quarter since 1990, construction of new transmission facilities has slowed.
The Department of Energy also says $60 billion in new investment in transmission, or about 12,650 miles of new lines nationwide, is needed by 2030 to get 20 percent of power from wind. Expanding the power grid is one trade-off of the national effort to expand clean energy technology and combat climate change.
"There's no question that we are changing the face of the state right now," said Brent Fenty, executive director of the Oregon Natural Desert Association in Bend, which is tracking transmission proposals in eastern Oregon. "And the important part is that we do that in a way that is responsible and reflects our values."

Most of Oregon's wind development has focused on the Columbia River Gorge, where there are existing transmission lines, farmers willing to lease their land for turbines and good wind, at least in the summer.
"If you take a look at maps of where the high-quality wind sites are, they're generally not where people live. And ultimately the energy that's produced needs to be delivered to consumers," said Brian Silverstein, senior vice president for transmission services at the Bonneville Power Administration.
The agency, which markets the power from federal dams, has 15,200 miles of transmission lines in Oregon, Washington, Idaho and Montana, that make up about three-fourths of the regional grid. And it proposes 225 miles of new lines, mostly to handle the increased energy production from new wind farms, Silverstein said.
Those thousands of miles of lines don't take into account the multitude of smaller feeder lines that will be needed to connect scattered wind projects to the grid. A good example is the roughly 50-mile line Columbia Energy Partners proposes to carry power from its planned wind farm on the north end of Steens Mountain in Harney County.
Originally envisioned to cross the Malheur National Wildlife Refuge, the line was rerouted after opposition from environmental groups. The new route would cross mostly private land, with six power poles proposed on Bureau of Land Management land, said Columbia President Chris Crowley. "Our project is permitted, and it's on private land. But to connect to the grid, we have to cross federal land. And that's proven to be the hook," Crowley said.
The BLM has 30 pending applications for transmission projects in the West, according to Interior Secretary Ken Salazar. On Wednesday, Salazar and other administration officials announced an agreement to streamline the permitting process for transmission projects on public land.
Simultaneously, Western states and federal agencies are trying to plot where new transmission corridors should be located based on where the renewable resources are greatest and potential environmental impacts the least. That includes the West-wide Energy Corridor, a plan to designate 6,000 miles of new energy corridors on 3 million acres of federal lands in Oregon and 10 other Western states where applications to build new pipelines or electricity lines would be expedited.
