The Minnesota Municipal Power Agency has started the construction of a $30-million renewable energy plant in the City of Le Sueur. The facility will collect agricultural and food processing waste to produce a source of electricity for the city. The plant will also help the municipal power agency reach a state mandate requiring a quarter of its power to come from renewable sources by 2025. The waste itself includes chicken manure, potato-processing residues and corn silage, and has been a major point of contention during the city’s approval process. Opponents said it would attract vermin and give off unpleasant odors. About half a dozen workers will be employed at the plant once it’s up and running, and around 100 jobs have been created during the construction phase. Work is expected to take about a year.
