What's ailing nuclear power

MIT electricity expert Jesse Jenkins is out with a new paper that looks to quantify the different forces that are jointly pushing down electricity prices enough to make nuclear power increasingly uneconomic.

  • The paper looks at the trajectory of wholesale power prices in the PJM Interconnection from 2008–2016. The region covers all or part of 13 states — including Ohio, Pennsylvania and Virginia — that are together home to about a third of the U.S. nuclear fleet.

The big takeaway: The 72% decline in market prices for natural gas is by far the biggest culprit, with flat power consumption and the growth of wind power playing lesser roles (with wind only a factor in the western parts of PJM).
