Coal-fired power plants around the country are closing due to environmental regulations and competition from cheap natural gas, but during hearings before the Indiana Utility Regulatory Commission earlier this month, officials from one of the state’s largest utilities sought to buck the trend.
Duke Energy Indiana is seeking permission from the state regulatory commission to bill ratepayers for making retrofits to three of its Indiana coal-fired power plants in order to comply with looming federal environmental regulations, most importantly the Mercury and Air Toxics Standard (MATS) with a 2015 deadline.
Environmental groups that submitted testimony at the hearing argued that investing in the aging coal plants is a bad deal for ratepayers, who will pick up the cost since Indiana is a regulated energy market. And, they say, it unwisely continues a dependence on electricity sources that emit high levels of carbon dioxide, further contributing to climate change.
Instead, they told the commission, Duke should invest in natural gas, energy efficiency and other options. The Indiana Citizens Action Coalition, Valley Watch, Save the Valley and the Sierra Club intervened in the regulatory proceedings (the Sierra Club is a member of RE-AMP, which also publishes Midwest Energy News).
The commission is currently considering Duke’s request to pass on about $400 million worth of pollution control investments to ratepayers for its Cayuga, Gibson and Gallagher coal plants, as phase two of an ongoing retrofit program. Duke told the commission it plans to close a fourth coal plant, the Wabash River station, though there is a possibility one of its units would be retrofitted as a natural gas plant. The average age of the four coal plants is 45 years. →
