Are transmission lines holding America back?
By Brad Plumer,
Here’s a striking data point on renewable energy from this new report by the President’s Council on Jobs and Competitiveness: There are currently 275,000 megawatts worth of proposed wind-power projects in the United States. For context, the capacity of the entire U.S. coal fleet, providing half of the country’s electricity, is 315,000 megawatts. Now, turbines aren’t a perfect substitute, because the wind isn’t always blowing, but that’s a huge amount of wind potential. So what’s holding those projects back? There just aren’t enough wires to connect them all.
By and large, the hurdles aren’t technological. They’re political. Dozens of agencies are typically involved in the permitting process. There are state authorities, plus hordes of independent grid-owners, plus landowners who would need to allow new transmission lines through their property, plus environmentalists worried that tramping new lines through places like the Mojave Desert will wreak havoc on endangered habitats. What’s more, many state governments aren’t thrilled with spending money on grid upgrades that would primarily benefit wind farms in neighboring states.
Technically, there’s a way to streamline this process. The 2005 energy bill gave the Department of Energy legal authority to approve large new transmission projects if states wouldn’t cooperate with one another. The jobs council report recommends the government use this authority. But that’s not so simple. Under George W. Bush, the department identified two grid areas — one in the Mid-Atlantic and one in the Southwest — as national priorities. But those areas spanned 10 states and 220 congressional districts. Fourteen senators from both parties (including Joe Biden!) quickly fired off a letter warning that the federal government was acting too aggressively.
That’s why a growing number of people who work in the industry are now questioning whether massive, centralized clean-energy projects really are the future. What good are huge solar farms in the desert if you can’t get them wired? Perhaps smaller, distributed sources of clean energy — rooftop solar panels, say, or small turbines — that don’t need fancy new transmission lines are a more promising option.
“It’s long been conventional wisdom that it’s much easier and cheaper to build those big plants,” Allan Schurr, vice president of strategy and development at IBM’s energy and utilities group, told me. “But, when we interviewed customers, we found a strong appetite for individuals having control over their own energy future.” As an alternate model, Schurr points to Germany, where well-crafted incentives for rooftop panels have transformed the cloudy nation into a solar leader. And there’s a lot of untapped potential here: the National Renewable Energy Lab has estimated that we have 661,000 megawatts of rooftop-solar resources here in the United States.
Does that seem difficult to imagine? Perhaps. Then again, every few months a new report comes out lamenting our need for big new transmission lines, and the political hurdles never seem to get any easier.
