Missouri utility regulators have given approval for what Ameren Missouri calls the most aggressive energy efficiency plan ever in the state.
Under the plan approved Wednesday by the Missouri Public Service Commission, Ameren will invest $147 million over three years in several programs that seek to reduce electricity use by 800 million megawatt-hours.
The plan was part of a negotiated settlement among Ameren, PSC staff, consumer advocates and environmental groups.
St. Louis-based Ameren serves 1.2 million electric and 127,000 natural gas customers in eastern and central Missouri.
