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.

‘Green Grocer’ takes on new meaning for Twin Lakes store

From an article in the Kenosha News:

TWIN LAKES — Installing energy-efficient lighting and controls is expected to save a Twin Lakes grocery store more than $28,700 a year eventually.

New equipment — mechanisms on freezers, cash registers and scales, and almost 650 lights — set up the past four months at Richter’s Twin Lakes Sentry, 600 N. Lake St., should cut utility costs enough to pay for the changes in less than five years.

The alterations are part of a “Green Grocer” program offered by the Wisconsin Grocers Association. The store will receive its Green Grocer certificate at 10 a.m. today during a store tour by representatives of various involved organizations. The public is invited.

Brett Hulsey, from Better Environmental Solutions, a Madison firm administering the program, said the western Kenosha County store is one of 10 certified in the state. The stores were in the service area of Wisconsin Power and Light, one of the program’s supporters.

The program now will expand outside that area, including Racine, Hulsey said. Kenosha grocers could take part by contacting the Wisconsin Grocers Association.

The program offers a low-interest loan to grocers to purchase the energy-efficient merchandise, costing up to $100,000 on average, Hulsey said. Savings will be used to pay off the loan. After that, it will translate to a reduced cost of business, he said. BES estimated the $28,700 savings at the Sentry store.

Plan would transform Monroe County landfill waste to energy

From an article in the Tomah Journal:

Solid Waste Manager Gail Frie offered a plan to generate energy and extend the life of Monroe County’s Ridgeville landfill at Monday’s meeting of the Solid Waste Management Committee. The committee approved $14,000 to begin the initial planning for the gas to energy project.

Frie, who was Vernon County’s solid waste manager for 18 years, said he had put a lot of study into the project. He said, “Every citizen of Monroe County should have a direct benefit from this project.”

The solid waste manager told the committee that he had “…done a lot of thinking…” on the plan so that the county had no cost. He did not want to tie up county bonding for a landfill project. He added that his focus was on saving money and extending the life of the landfill.

The gas to energy project is a $6 million proposal funded with United States Department of Agriculture grants and loans and funds from partners including Alliant Energy, Focus on Energy and Gundersen-Lutheran. Food waste would be the principal source of energy. The county would save over $500,000 in landfill operation costs. Gundersen-Lutheran would buy the electricity generated by the plan.

We Energies' wind park offers significant benefits to the state

From the written decision of the Public Service Commission on We Energies’ Glacier Hills Wind Park:

WEPCO’s [We Energies’] wind-powered electric generating facility is a renewable resource that offers significant benefits to the state of Wisconsin. The air pollution and greenhouse gas emissions it avoids, the lack of solid waste, and the fact that it consumes virtually no water are important environmental benefits. This project will support the state’s goal of increasing its reliance upon renewable resources and will help diversify Wisconsin’s pool of electric generating facilities. It fits well with existing land uses, will help preserve the agricultural nature of the project area, will impose no reliability, safety, or engineering problems upon the electric system, and will create no undue adverse impacts on environmental values. After weighing all the elements of WEPCO’s project, including the conditions imposed by this Final Decision, the Commission finds that issuing a CPCN will promote the public health and welfare and is in the public interest. The Commission also finds that, while members of the public are concerned about possible health effects associated with the project, there is not sufficient evidence in the record to conclude that the project would cause adverse health effects.

Wisconsin wind map shows potential around St. Croix

Wisconsin wind map shows potential around St. Croix


From the announcement of a new map of winds published by the U.S. Department of Energy:

The Department of Energy’s Wind Program and the National Renewable Energy Laboratory (NREL) published a new wind resource map for the state of Wisconsin. The new wind resource map shows the predicted mean annual wind speeds at 80-m height. Presented at a spatial resolution of 2.5 km (interpolated to a finer scale for display). Areas with annual average wind speeds around 6.5 m/s and greater at 80-m height are generally considered to have suitable wind resource for wind development.

Additionally, a national dataset was produced of estimated gross capacity factor (not adjusted for losses) at a spatial resolution of 200 m and heights of 80 m and 100 m. Using AWS Truewind’s gross capacity factor data, NREL estimated the windy land area and wind energy potential in various capacity factor ranges for each state. The table (Excel 75 KW) lists the estimates of windy land area with a gross capacity of 30% and greater at 80-m height and the wind energy potential from development of the “available” windy land area after exclusions.

Though difficult to see on the small image above, an area around in St. Coix County stands out for wind speeds higher than much of the rest of Wisconsin.

Communication will help rally support for Domtar biomas project

From an editorial in the Wausau Daily Herald:

Outside a recent open house WE Energies held to discuss its proposed biomass power plant in Rothschild, a group of residents distributed information outlining their concerns and objections to the plant.

It’s good for people to be engaged in a local matter that affects them, and we applaud residents for voicing their concerns. But in our judgment, the benefits that the biomass plant would bring our area far outweigh the costs.

The $250 million power plant would be a boon to the area, full of upsides. It would provide an economic boost, both in the 400 construction jobs required to build it and in the 150 permanent jobs that would staff the plant. It would boost the state and municipal tax base. And the technology it would employ is clean, renewable and low-emission, helping Wisconsin reach its goal of using 10 percent renewable energy by 2015.

The biomass plant, which would power the Domtar paper mill and provide electricity to the grid, would be fueled by burning wood waste — low-quality wood, unusable bark and such. That’s a good deal cleaner than burning coal and fossil fuels, and it’s a renewable resource.

This project needs to happen. WE Energies is waiting on state approval to begin construction, but says it hopes to have the plant up and running by fall of 2013.
