Power-to-heat WARMTH
FOR THE MÜMMELMANNSBERG DISTRICT

By coupling modern CHP technology with an innovative power-to-heat system, the Mümmelmannsberg district is supplied with heat from electricity for our customer SAGA in Hamburg. And that's not all: The plant, which is coupled to the transmission grid of our cooperation partner, 50Hertz, goes into operation whenever there is an oversupply of renewably generated wind or solar power in the power grid. Climate-friendly and grid-serving sector coupling at its best.

THE cUstomized GETEC ENERGY SOLUTION

THE CHALLENGE

A climate-friendly and, at the same time, economical heat supply is to be provided for the Mümmelmannsberg district in the eastern Hamburg quarter of Billstedt. The supply area includes 7,000 apartments and commercial units.

THE OBJECTIVE

The project is expected to benefit increasingly from the medium-term expansion of renewable energies and successively increase the supply of heat generated from renewable electricity to the urban district. In the end-use stage, this is expected to substitute more than 20,000 MWh of gas per year, which corresponds to a CO2 saving of more than 3,600 metric tons per year. In addition to supplying the district with increasingly climate-friendly heating, the aim is also to relieve the burden on the power grid and thus avoid unnecessary costs for the shutdown and remuneration of EEG plants.

THE SOLUTION

GETEC already operates two modern combined heat and power (CHP) plants in Mümmelmannsberg, which supply around 7,000 apartments and commercial units with heat and electricity simultaneously. The power-to-heat system is being built with our cooperation partner, 50Hertz. In the event of strong winds and increased electricity supply, the CHP units are downregulated. The PtH plant with a capacity of 5 MW then converts the electricity from renewable energies into emission-free district heating for heating and hot water in an electrode boiler. CHP and PtH plants are coordinated by intelligent control technology.
