Dive Summary:

• In a settlement with the Sierra Club, Duke Energy has agreed to stop burning coal at Wabash River Station in Indiana by June 2018 and develop more renewable resources.
• The settlement will allow Duke to keep its air permit for the new Edwardsport coal gasification plant.
• Before the settlement, Duke had planned to shutter at least four of the five coal units at Wabash to meet the Environmental Protection Agency's 2015 standards for the Mercury and Air Toxics Standards.

From the article:

“The settlement also includes a requirement that Duke pursue additional green energy sources by either implementing a 30 MW feed-in tariff for solar photovoltaic energy or constructing or contracting for 15 MW of wind and/or solar power generation.”
