In Burlington, Vt., the 50-megawatt McNeil power station has been operating successfully since 1984, using mostly leftover branches, leaves and stumps generated by people harvesting firewood or lumber. Plant manager John Irving said McNeil breaks even at 5.5 cents per kilowatt/hour. (To compare, the typical Florida utility customer pays the utility 10 to 13 cents/kWh.)
The price for McNeil power fluctuates depending on alternative sources. "There were some times when oil/gas was very cheap when I'm sure our owners were thinking maybe we should have done something else," Irving said in an e-mail. But lately, the utility has been getting 10 or 12 cents/kWh, plus a 3-cent bonus from Connecticut for providing clean energy. "They're pretty happy now," Irving said of the owners.
