Chart: The US clean energy backlog is getting bigger and bigger

A recent report from Lawrence Berkeley National Laboratory highlights a significant increase in proposed clean energy projects awaiting approval. The backlog, known as the interconnection queue, has ballooned to approximately 2.6 terawatts, double the size of the current U.S. electrical grid. This surge in interest is driven by various factors, including emission reduction targets, clean energy incentives, and declining costs.

The lengthy process for projects to navigate through the queue, now averaging nearly five years, presents a challenge to meeting clean energy goals. While the completion rate of such projects historically remains low, the scale of potential development remains substantial. Efforts to address the bottleneck include recent regulatory reforms and proposed solutions from the Department of Energy.
