Ameren eyes more renewable energy with approval of ‘green tariff’

Finding a supply of renewable energy to match demand for it from certain Ameren Missouri customers could become easier thanks to the St. Louis-based utility receiving regulatory approval of its Renewable Choice Program.

The program, approved last week by the Missouri Public Service Commission, will let municipalities, large commercial users and other customers who meet a threshold for energy use essentially subscribe to receive 100 percent renewable energy.

It’s an example of a “green tariff,” or a program through which the electricity a user buys is “matched” by a utility’s purchases of renewable energy.

The utility is expected to gauge interest from potential participants in the coming months, and then identify sources to meet projected demand.
