A survey of six stand-alone wood-based electric power generation plants in Michigan assessed facility operating characteristics, fuel characteristics, sources of wood, and operators' views on wood supply and needed policy changes. Survey results provide insights regarding the role of these renewable energy plants in meeting Michigan's Renewable Portfolio Standard (RPS). The plants have long-term power supply agreements with Consumers Energy Company; they produced the bulk of renewable energy for Consumers in 2009. The six plants were the only wood-burning electric generating facilities operating in Michigan during 2008, the base year for the survey. Each plant employed 22 people, on average, to operate the facility. The three smaller plants generated 18.4 MW on average in 2008 and used 195,954 tons (177,766 metric tons) of wood fuel. Larger plants produced 27.7 MW on average and consumed 323,915 tons (293,851 metric tons) of wood fuel. Green wood from logging residues was the largest source of material. The second largest wood fuel source in 2008 was chips, but managers noted that this was an anomaly driven by depressed activity in the wood products industry. Given the economic downturn in 2008, more logs and chips were available for power generation. Most facilities supplemented their wood fuel with tire-derived fuel. Managers identified several policy changes that would encourage stability and growth in their industry, most related to wood fuel supply.
