The North Omaha Station, a coal burning power plant, was supposed to stop burning coal next year. But its owner wants an extension to keep burning coal for three more years.

Ameren Missouri plans to buy a solar power plant in Bowling Green, Missouri, that could produce energy by 2024. The announcement comes days after it shared plans to open a natural gas plant. Both facilities need approval from Missouri’s Public Service Commission.
