Wind energy's success creates a power grid challenge
October 29, 2009 by Matthew Preusch in The Oregonian

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. ...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.

Winds of change; Power projects drive billions in grid upgrades

When the wind blows, a massive amount of power flows to the grid and "any time you get that amount of power into the auction system of the power pool, it's going to crush price," said Rob Falconer, director of distributed generation for the utility.
The push to buy carbon offsets in a carbon-constrained world plays a strong role in developers' estimating profit margins, but existing uncertainty over prices makes the debate over sinking billions of dollars into extensive transmission projects even more relevant, he said.

Rupert Soames, the chief executive of Aggreko, the FTSE 250 emergency power generator, says the UK must prepare seriously for the danger of being hit by similar blackouts within the next decade.
"It has happened before in developed countries and we should not kid ourselves that it cannot happen here," he said in an interview with The Sunday Telegraph.
"The UK has an unacceptably high risk of interrupted power supply." ...sceptics worry that a so-called "intelligent grid" could also be used to ration consumers in the event of insufficient capacity.

Out-of-state power projects criticized; Utilities trying to meet mandate for renewables

In May, 62 wind turbines started sending electricity from southern Washington state to the Turlock Irrigation District.
Next year, a nearby wind project in northern Oregon will start supplying the Modesto Irrigation District. ...Outsourcing renewable power irks some activists. "It totally takes the focus off building our green-tech economy," said Laura Wisland, a clean energy analyst with the Union of Concerned Scientists in Berkeley.

Wyoming's recent rush on wind power led by utility giant Rocky Mountain Power could settle out during the next year and not pick up again until major new power lines begin connecting to the state in 2014.
But even that's not a given.
"Good luck getting financed," said Nate Sandvig, project manager for Horizon Wind Energy.
Wind proponents say credit markets make it difficult for independent generators and transmission companies to get into the game.

Wind promises blackouts as Obama strains grid with renewables

President Barack Obama's push for wind and solar energy to wean the U.S. from foreign oil carries a hidden cost: overburdening the nation's electrical grid and increasing the threat of blackouts.
The funding Obama devoted to get high-voltage lines ready for handling the additional load of alternative supplies is less than 5 percent of the $130 billion that power users, producers and the U.S. Energy Department say is needed.
