L'Anse Warden Electric Company (LWEC)

LWEC is a 20 Megawatt power plant located on the shore of Lake Superior in the Upper Peninsula of Michigan. LWEC supplies electric power to DTE under a power purchase agreement for renewable energy. The plant also supplies steam and electricity to the CertainTeed Plant that is adjacent to LWEC in L’Anse. As such, the LWEC Plant cogenerates both steam and electricity for sale.

LWEC is currently fueled with a combination of renewable fuels including: wood chips, wood by-products, and railroad ties. In addition, LWEC burns tire-derived fuel (TDF) that falls under the U.S. EPA alternative fuels program. The TDF we use is considered a partially renewable fuel and offers a low moisture, high Btu fuel that improves the heat rate of the plant, helping the biomass combust more efficiently. TDF comprises a small portion of the overall fuel mix at less than 10%.

In addition to LWEC, Convergen Energy is working to either acquire or partner with other solid fuel power and/or steam generating facilities that utilize:

• wood biomass
• agricultural biomass
• alternative fuels such as TDF, Pellets, CD Materials, and the like
• blends of fuels incorporating the above types
• coal plants needing to switch fuels for cost and/or environmental compliance

We also invest in alternative and advanced energy projects, such as such as gasification, distributed generation, and other similar advanced technology to provide long-term reliable base load energy supply from the CE engineered solid fuel pellets, as well as from other renewable resources such as landfill gas and biogas.

The global debate on carbon footprint reduction, coupled with the rising cost of traditional energy sources and methods, means the need for cleaner power has never been greater. A growing number of customers are recognizing the advantages that Convergen Energy solutions can deliver. These include major single-site organizations with energy generation needs, such as municipalities, universities, hotels, hospitals, manufacturers, and industrials with large quantities of non-recyclable residuals.
