The Stadtwerke Flensburg municipal works company is taking part in the Norddeutsche EnergieWende (NEW 4.0) project, a press release said Wednesday (October 2017). In July, construction of an 800 kW electro boiler began to turn excess electricity from renewable energies into storable heat in the Tarp district heating system. The new facility can react to fluctuating amounts of electricity in seconds and help achieve grid balance and in terms of demand and supply.
Challenge of fluctuating amounts of electricity
Crucially, the load and availability of electricity has to be balanced out which can have a huge impact on the power grid. Wind power, photovoltaic and cogeneration units require different facilities for feed-in power depending on wind and sunshine for renewable energy. The planned electro boiler can replace a cogeneration unit’s district heating output with electric heat. This saves fossil fuels and uses local wind energy.
