I'm unclear about why the remedies for permit/project cancelations are designed this way. Happy to be corrected on any of this, but this bill feels like a *gigantic* adverse selection problem waiting to happen. I've got a few questions:

Companies like GE killed their coal businesses in the first Trump administration, because there is no amount of political wish-casting that can make it competitive with solar, wind and gas. I don't think there are any domestic boiler OEMs left. This stuff is a waste of everyone's time.

PJM's attitude towards ratepayers and elected officials within its territory has been off-putting to say the least. I'm impressed with this op-ed by David Lapp at the Office of People's Counsel in MD, which I think makes the argument very persuasively: www.utilitydive.com/news/pjm-ceo...

PJM leadership openings are an opportunity to chart a new course
Rather than addressing the root causes of its problems, the organization blames states for supply and infrastructure shortages, often defending the very policies that are driving up customer costs.

There's a lot of attention paid to Chinese dominance of critical minerals. Much less to control of grid components and subcomponents - even after a physical backdoor was discovered in a Chinese transformer in 2020. The grid is a national security issue, full-stop. Good report from SAFE.
