Pennsylvania’s Portland Generating Station will switch from coal to diesel.
Plant owner, NRG Energy (NYSE: NRG), shut down its coal-fired boilers June 1, but hope to have the boilers burning low-sulfur diesel fuel to generate electricity by 2016.
The plant will likely operate on peak days, NRG Energy spokesman David Gaier said. He noted that after the retrofit, nitrogen oxide emissions should decline by about 95 percent; sulfur dioxide by about 99 percent; and carbon dioxide by 93 percent.
"The plant will run much less often overall, and therefore its total emissions will be dramatically reduced," he said.
New Jersey Department of Environmental Protection Spokesman, Larry Hajna, added that the ultra-low sulfur diesel's sulfur dioxide output is similar to natural gas.
“However, nitrogen oxide emissions, which cause smog, can still be high using ultra-low sulfur diesel unless proper control equipment is installed," said Hajna. "We are committed to working to making sure Pennsylvania requires these controls."
NRG shut down the boilers after a 2007 lawsuit settlement brought by Connecticut and New Jersey.
