Generators now on drawing boards will be left uneconomical
Natural gas-fired power plants, which have crushed the economics of coal, are on the path to being undercut themselves by renewable power and big batteries, a study found.
By 2035, it will be more expensive to run 90% of gas plants being proposed in the U.S. than it will be to build new wind and solar farms equipped with storage systems, according to the report Monday from the Rocky Mountain Institute. It will happen so quickly that gas plants now on the drawing boards will become uneconomical before their owners finish paying for them, the study said.
The development would be a dramatic reversal of fortune for gas plants, which 20 years ago supplied less than 20% of electricity in the U.S. Today that share has jumped to 35% as hydraulic fracturing has made natural gas cheap and plentiful, forcing scores of coal plants to close nationwide.
