As stars align for America’s rapid transition to a clean economy, slow electric transmission project permitting is gumming up the gears.
The vast majority of newly-installed and planned energy projects in the U.S. consist of clean energy – solar and wind farms, often paired with battery storage - even before the Inflation Reduction Act (IRA) expanded the tax credits available to incentivize low-carbon electricity. Economics, policy, and public demand are now all aligned in favor of clean energy.
But as a recent report from Lawrence Berkeley National Laboratory (LBNL) highlights, a growing number of clean energy projects are getting stuck in what are known as “interconnection queues.” In the 2000s, these projects waited an average of two years for the determination about whether the electric grid could handle their added power load. In the 2010s that wait time nearly doubled, to 3.7 years, and a growing number of clean energy projects have been canceled as a result of these lengthy delays.
The key bottleneck? Too-slow construction of new electric transmission lines (especially long-distance lines) to transport electricity from the exploding number of proposed clean energy projects to the places where it’s needed. If not addressed, transmission project delays caused by factors like an onerous permitting process could dramatically hamper America’s clean energy rollout and thus its ability to cut pollution fast enough to meet the country’s Paris commitments.
As a result, some experts believe that climate advocacy in the U.S. may need to shift from a focus on stopping fossil fuel infrastructure to one that centers on enabling the clean energy infrastructure that will displace it.
Demand is shifting from fossil fuels to clean energy
Another new LBNL report finds that America’s energy landscape has shifted dramatically over the past decade. About 60% of new energy installations built in the U.S. in 2011 were fossil fuels (mostly fossil gas) compared to just 40% from renewables (mostly wind). In 2021, 85% of newly installed energy capacity came from clean sources (primarily solar), and the remaining 15% from fossil gas. Of the proposed energy projects currently in the queue, LBNL reports that more than 92% are wind and solar – nearly one-third proposed to be coupled with battery storage – compared to just 7.5% from natural gas. .
