NY & IL have already intervened. CT, NJ, others debating action now.
Lower demand obviously means lower prices. Straightforward effect. So that's suspect #2.
Here are my primary results.
The graphic makes it obvious: natural gas is the main killer. Effect of gas is order of magnitude larger than wind or demand.
For ALL OTHER nuclear plants in PJM, wind does not appear to have statistically significant effect on prices earned.
That said, stagnant electricity demand and expectations of future growth in wind generation going forward may be accomplices.
Case closed? /end
