Clearing up Wisconsin’s lakes with clean digester energy

From a commentary by Michael Vickerman, RENEW's executive director:

In the next six weeks the Legislature will make a truly momentous decision on the state’s energy future. Either it can embrace an ambitious 15-year commitment to invigorate the state’s economy through sustained investments in clean energy or decide to coast along on current energy policies until they lapse and lose their force and effect.

Arguably the most innovative feature in the Clean Energy Jobs Act, as it’s now called, is a proposed requirement on larger electric providers to acquire locally produced renewable electricity with Advanced Renewable Tariffs (ARTs). These are technology-specific buyback rates that provide a fixed purchase price for the electricity produced over a period of 10 to 20 years, set at levels sufficient to recover installation costs along with a modest profit. Now available in more than a dozen nations in Europe as well as the Province of Ontario, ARTs have proven to be singularly effective in stimulating considerable growth in small-scale production of distributed renewable electricity. . . .

Consider the much-vaunted Dane County Cow Power Project, which should be operational before the end of the year. Using anaerobic digestion technology, this Waunakee-area installation will treat manure from three nearby dairy farms and produce biogas that will fuel a two-megawatt generator. This community digester project, the first of its kind in Wisconsin, will be built with private capital and a State of Wisconsin award to support a technology that reduces the flow of phosphorus into the Yahara Lakes. A second digester project is also planned for Dane County.

The key element that makes the financing of this project work is the special biogas buyback rate that Alliant Energy, the local utility, voluntarily put in place a year ago. With the higher rate, the project’s return on investment was sufficient to interest outside investors. . . .

If we are serious about neutralizing the algae blooms that turn the Yahara lakes green each year, we’ll need to adopt a clean energy policy, including ARTs, that facilitates the development of biodigesters in farm country.
