Are transmission lines holding America back?

Transmission Permitting Reform aims to streamline grid planning, interstate transmission lines, and approvals for renewables, easing political hurdles while complementing distributed energy like rooftop solar and small turbines to meet clean energy goals.

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.

Transmission is an underrated issue in energy policy. The process for locating and permitting new wires was established way back in 1935, when most power plants were situated close to the people who used the electricity. That process works okay for building a natural-gas turbine near town. It’s not as useful for transporting wind power that often pushes the grid to its limits from large, remote farms out in North Dakota to cities in California. Right now, building big new transmission lines is an enormous hassle, and a lack of new power lines is threatening renewable growth across markets. One 90-mile line from West Virginia to Virginia, the council report notes, took American Electric Power 13 years to site. Is that fixable?

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, where power line projects face opposition from multiple sides, 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 facing a transmission glass ceiling today.

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, and that a smart grid for wind and solar can help integrate, are a more promising option.

“It’s long been conventional wisdom that it’s much easier and cheaper to build those big plants, even as the wind industry faces transmission constraints in many regions,” 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, even as stimulus has fanned growth for wind producers nationwide, and the political hurdles never seem to get any easier.
