SUMMIT COUNTY — Proposed new limits on power plant emissions could spur a big shift away from coal and toward natural gas. The new rules on sulfur dioxide, particulate matter, nitrogen oxide and mercury may make nearly two-thirds of the nation’s coal-fired power plants as expensive to run as plants powered by natural gas, according to a new Duke University study.
“Because of the cost of upgrading plants to meet the EPA‘s pending emissions regulations and its stricter enforcement of current regulations, natural gas plants would become cost-competitive with a majority of coal plants — even if natural gas becomes more than four times as expensive as coal,” said Lincoln F.
