"Since the first ZECs eligibility period began, power markets have deteriorated significantly, thus the financial needs of New Jersey's nuclear plants have continued to grow. Nationwide, nuclear plants continue to struggle economically to survive. Since 2018, three nuclear plants have closed in the eastern U.S., all for economic reasons, and the impact has had a ripple effect."
So, they aren't blaming regulations, they're blaming the fact that the power markets have "deteriorated" ie. there is less money to be made.
Nuclear clearly hasn't become cheaper, and neither have fossil fuels, so what exactly has led to this cheaper electricity if it isn't the plummeting price of renewables?
