Abstract
We use emergency outages of coal and gas generators in PJM as an exogenous source of variation in the power generation stack to study how changes in the marginal fuel source affect real-time wholesale electricity prices. Our results cast significant doubt on anecdotal evidence that natural gas generation leads to higher electricity price volatility. We find that wholesale prices are less volatile when natural gas is on the margin more often.
