Lempäälän Energia Oy is an energy production company and the operator of the Marjamäki area’s Lemene energy system. We produce district heating using biomass-based production methods in two different heat plants. Electricity is generated using solar power and a combined production method that also produces heat in addition to electricity. The produced electricity supports the Nordic electrical grid, and with industrial-scale battery systems, we participate in balancing national power grid consumption and production.
