From a news release issued by Alliant Energy:
Biomass burns to resume at Nelson Dewey Generating Station in spring 2011
MADISON, WI – December 30, 2010 – Wisconsin Power and Light Company (WPL), an Alliant Energy company, will build upon the success of its 2010 biomass test burns by expanding those efforts in 2011, burning larger quantities of biomass for longer durations at the Nelson Dewey Generating Station in Cassville, WI.
WPL has received a Research and Testing Exemption (RTE) from the Wisconsin Department of Natural Resources (WDNR) that allows for up to a 50 percent co-firing of biomass over a 12 month period within the facility’s two cyclone fired boilers. While that approval came this week, the 12 month period won’t actually begin until the test burns begin. WPL anticipates that will happen this spring.
“With the potential that biomass presents to create Wisconsin jobs and build upon a new and developing economic market for Wisconsin farmers, expanding our test burns at Nelson Dewey is the next step in our focus on balanced generation,” explains John Larsen, Senior VP Generation – Alliant Energy & President – WPL. “As we continue to manage costs overall as a company, we are also managing our generating fleet to reduce our reliance on market purchases and remain flexible to adapt to change.”
WPL will continue to examine a number of factors during the test burns in 2011, including environmental impacts, supply chain capabilities, material delivery and handling costs and the blending and combustion of biomass based materials within the current plant configuration. No permanent structures or modifications will be made to the existing facility’s equipment to accommodate the test burns.

A news release for the Wisconsin Office of Energy Independence:
First-of-its-kind pilot size study to turn organic waste and
biobased plastics into a clean energy resource
MADISON, WI – In an effort to turn an organic waste stream and biobased plastics into an energy resource, the Office of Energy Independence, University of Wisconsin – Platteville (UW-Platteville), and UL – EnvironmentSM (UL-E) an Underwriters Laboratories Company, have joined forces to conduct the first pilot study in the nation to test anaerobic digestion of bioplastics as a co-feedstock.
“When perishable foods, such as meat or dairy items, reach the end of their shelf-life, the store must remove the product for proper disposal to a landfill,” said Judy Ziewacz, Director for the Office of Energy Independence. “If successful, the food packaging and plastic industry would be able to turn a waste expense into a profitable energy generator.”
Annually, more than 830,000 tons of organic waste is sent to Wisconsin landfills. If this waste was diverted to a digester, it could potentially generate 5 megawatts of renewable energy to power 5,000 homes.
UW–Platteville, with scientific partner UL-E, will use an existing 4-stage digester built by Hanusa Renewable Energy to run the pilot study.
“The pilot scale digester is the only one of its kind in the nation that we are aware of,” said Tim Zauche, Chemistry and Engineering Physics Chair at UW-Platteville. “If we can determine bioplastic can be processed through the system, then the question becomes will it contribute to renewable gas production and a quicker return on investment.”
“Business owners are seeking innovation to lower their environmental footprint,” said Joe Mecca, Business Development Manage for UL-E. “This has great potential to reduce waste-to-landfill while producing renewable energy. We look forward to working with UW-Platteville to test the feasibility of this concept and setting guidelines for the marketplace.”
The study will be conducted at Pioneer Farm, located about 5 miles southeast of the city of Platteville. Pioneer Farm is a key component of the Wisconsin Agricultural Stewardship Initiative, a statewide
collaboration between producers, state government and the University of Wisconsin System to evaluate best management practices in Wisconsin and form policies based on practices that will enhance the environment and produce a profit for business.

From an article by Jake Miller in the Wausau Daily Herald:
ROTHSCHILD — Union leaders, village officials and small business owners were among the overwhelming majority who spoke Tuesday in favor of a proposed — and highly debated — biomass plant.
Only four of the 43 speakers opposed the plant during the first of two public hearings held by the Wisconsin Public Service Commission, which will assess the comments when deciding whether it will approve the project in mid-January, said Administrative Law Judge Michael Newmark.
We Energies and Domtar first proposed the plant, which will burn a woody biomass as fuel, in September 2009. It has been at the center of public debate for nearly as long.
At the afternoon hearing attended by about 200 people — another hearing was held Tuesday evening — supporters continued to argue that the biomass plant is critical to keep Domtar competitive and that it will create both temporary and permanent jobs.
Opponents stood strong, saying the plant, which is expected to burn 500,000 tons of biomass each year, will adversely affect air quality despite We Energies data that say emissions would be cut by 30 percent.
Jeff Morzenti, an employee at the Domtar Mill in Rothschild for more than 25 years, said he is one of those responsible for monitoring what exits the mill’s smoke stacks.
Not just as an employee, but as a longtime resident of Weston, the 51-year-old Morzenti said he wouldn’t support the plant if he didn’t believe it was safe.

From an article by Tom Content in the Milwaukee Journal Sentinel:
Xcel Energy Inc. on Monday halted plans to build a biomass power plant on Lake Superior in Ashland.
The utility holding company’s Eau Claire-based utility informed the state Public Service Commission of its decision in a letter Monday.
Xcel had planned to build a biomass gasification plant that would have made the Ashland power plant the largest wood-burning power plant in the Midwest.
The decision came as a result of a significant increase in the cost of the project, as well as declining costs for other generation options. The utility also cited “considerable regulatory uncertainty at the state and federal level.”
The announcement was made one day before the start of Public Service Commission hearings on a separate biomass power plant, proposed by Milwaukee-based We Energies to be built at the Domtar paper mill in Rothschild.
The timing of the announcement was coincidental and not linked to the We Energies proposal, said David Donovan, Xcel manager of regulatory policy.
“Although we are disappointed with the outcome, we have gained considerable value from the evaluation that we have completed,” said Mike Swenson, president and chief executive of NSP-Wisconsin, a unit of Xcel Energy, in a statement.
“The engineering studies will advance gasifier technologies for utility applications and our efforts to procure sustainable biomass supplies have resulted in a model that can be adopted in future projects,” Swenson said. “In addition, as part of this project we helped fund the development of two biomass energy plantations in northern Wisconsin, which will provide valuable research and study opportunities for decades to come.”
Those plantations are testing the development of hybrid poplar and black willow trees for harvesting and burning at the power plant.

From an article by Tom Content in the Milwaukee Journal Sentinel:
As a new administration prepares to take office in Madison, with a different attitude toward renewable energy than the Doyle administration, We Energies is pressing forward with plans to build a wood-burning power plant in north-central Wisconsin.
The state Public Service Commission will hold a hearing on the project this week, with a decision expected early in 2011.
Concerns about greenhouse gas emissions, the cost of the project and even competition for biomass are all being reviewed as the proposal makes its way through the state approval process.
We Energies is optimistic, as it has won all the local approvals it needs from officials for the Village of Rothschild and the Village of Weston, utility spokesman Brian Manthey said.
“We believe we’ve answered every question that has come up, and we are pleased that we’ve gotten unanimous support from the municipal boards for the project,” he said. “We’ll continue to supply the information needed to move the project forward at the state level.”
The $255 million project at the Domtar Corp. paper mill in Rothschild, south of Wausau, would generate 50 megawatts of electricity, enough to power about 40,000 typical homes. It also would provide steam for the Domtar mill. . . .
The $255 million cost of the Domtar project is also raising concerns.
An analysis by auditors at the PSC found that building a wind farm would be less expensive for customers than building this project. The commission suggested that We Energies explore the possibility of burning wood in conjunction with coal at some of its existing coal-fired power plants, such as its older coal plant in Oak Creek.
An estimate by the customer group Citizens’ Utility Board found the plant would be twice as expensive as a similar-sized wind farm, executive director Charlie Higley said.
While the cost may be higher, We Energies said the utility wants to diversify its renewable energy sources beyond wind. And unlike wind and solar projects, biomass power plants have the added benefit of being able to run round the clock.
In addition, Allan Mihm, We Energies director of generation projects, said the project is more efficient because it’s supplying electricity and steam. It would cost the utility $20 million more to build a power plant separate from the paper mill, he said.
