The Bureau of Land Management says it will be heavily scrutinizing transmission lines if they are expressly necessary to bring solar or wind energy to the power grid.
Since the beginning of July, I’ve been reporting out how the Trump administration has all but halted progress for solar and wind projects on federal lands through a series of orders issued by the Interior Department. But last week, I explained it was unclear whether transmission lines that connect to renewable energy projects would be subject to the permitting freeze. I also identified a major transmission line in Nevada – the north branch of NV Energy’s Greenlink project – as a crucial test case for the future of transmission siting in federal rights-of-way under Trump. Greenlink would cross a litany of federal solar leases and has been promoted as “essential to helping Nevada achieve its de-carbonization goals and increased renewable portfolio standard.”
Well, BLM has now told me Greenlink North will still proceed despite a delay made public shortly after permitting was frozen for renewables, and that the agency still expects to publish the record of decision for the line in September.
This is possible because, as BLM told me, transmission projects that bring solar and wind power to the grid will be subject to heightened scrutiny. In an exclusive statement, BLM press secretary Brian Hires told me via e-mail that a secretarial order choking out solar and wind permitting on federal lands will require “enhanced environmental review for transmission lines only when they are a part of, and necessary for, a wind or solar energy project.”
However, if a transmission project is not expressly tied to wind or solar or is not required for those projects to be constructed… apparently, then it can still get a federal green light. For instance in the case of Greenlink, the project itself is not explicitly tied to any single project, but is kind of like a transmission highway alongside many potential future solar projects. So a power line can get approved if it could one day connect to wind or solar, but the line’s purpose cannot solely be for a wind or solar project.
This is different than, say, lines tied explicitly to connecting a wind or solar project to an existing transmission network. Known as gen-tie lines, these will definitely face hardships with this federal government. This explains why, for example, BLM has yet to approve a gen-tie line for a wind project in Wyoming that would connect the Lucky Star wind project to the grid.
At the same time, it appears projects may be given a wider berth if a line has other reasons for existing, like improving resilience on the existing grid, or can be flexibly used by not just renewables but also fossil energy.
So, the lesson to me is that if you’re trying to build transmission infrastructure across federal property under this administration, you might want to be a little more … vague.
