Minnesota & Wisconsin
Operator: Great River Energy
Configuration: 2 X 11.5 MW, 1 X 22.5 MW
Fuel: RDF, gas
Boiler/incinerator system supplier: Springfield, Riley Stoker
T/G supplier: Elliott
Quick Facts: Elk River began operation burning coal and oil. Beginning in 1963, the site hosted a 22-MW demonstration nuclear unit, and was then reconverted to coal and oil in 1968, and converted again to RDF in 1989. Daily fuel burn is about 1,250 tons, derived from 1,500 tons of MSW collected from five Minnesota counties.

Quick Facts: Red Wing has two stoker boilers built for coal-firing and converted to RDF fuel in 1986. RDF is sourced from resource recovery facilities in Elk River and Newport, MN, which collect and process approximately 790,000 tpy of MSW. In 1998, The plant was retrofit with a dry lime scrubber and baghouse as part of a $12mn environmental improvement program. Red Wing burns about 200,000 tpy of RDF.
