Not surprising. More and more renewables keep getting built. April is a shoulder month for load so a lot of coal plants go offline in April for planned maintenance. I don't know about wind nationwide but April is generally the month with the highest production for our wind units. A lot of snowpack and spring rains this year probably also pushed hydro up in April as well.JohnStOnge wrote:Here's an interesting tidbit:
Also note this graph in the article:In April 2019, U.S. monthly electricity generation from renewable sources exceeded coal-fired generation for the first time based on data in EIA’s Electric Power Monthly.
Trump is BSing about coal. It's not happening.
Coal isn't coming back. But that is more to do with federal subsidies and rate making policies. The subsidies on wind drive energy markets negative or below the marginal fuel cost for coal and nuclear units, making them unprofitable so utilities want to shut them down. Utilities with marginal units that are fully depreciated are more likely to shut them down permanently because they no longer gain any value from them. Building wind, and putting the capital cost in to the rate base, means getting a 10% ROE on the new investment so utilities have an incentive to build. It's a win-win for the utilities - shut down a "dirty" coal plant and build renewables to make you look good and increase your ROE. What should concern everyone is that this is not only impacting coal but is also impacting nuclear plants. If you believe in the climate crisis than we should not be shutting down nuclear plants.
