Legislation affecting 2008′s Proposition C is making its way through the Missouri General Assembly. The mandate, which was approved by 66 percent of voters, requires utility companies to use new renewable energy sources for 15 percent of their power by 2021. House Bill 44 would allow hydropower that already exists to be counted in that total.
Hickey said if lawmakers change the formula to include existing hydropower plants, an equivalent of three new large wind farms might not be built.
Hickey said Missouri stands to benefit from more than $2 billion in economic development and thousands of new jobs if new wind and solar resources are built in the next few years under the Renewable Energy Standard.
The organization Renew Missouri has already filed a complaint with regulators accusing Ameren of trying to circumvent the standards. Ameren denies this charge.
