"Photovoltaics will become one of the most important sources of generating power in future. The expansion of photovoltaics is important for achieving our climate protection goals and ensuring an affordable electricity supply," said Katharina Fegebank, Senator for Science, Research and Equality. The new PV system on the roof of the Centre for Hybrid Nanostructures is expected to generate around 140,000 kilowatt hours of green electricity per annum and save around 45,000 kilograms of CO2 emissions. This could supply around 55 households with an average 2,500 kWh per year.
System on Centre for Hybrid Nanostructures to supply 14,000 kilowatts of green electricity annually
HEnW KommunalEnergie, a subsidiary of Hamburger Energiewerke, has installed the largest photovoltaic (PV) system to date on the roof of the Centre for Hybrid Nanostructures (CHyN) in Science City Hamburg-Bahrenfeld. The system is on a 750 square-metre area and marking another step towards the energy transition.
Achieving energy transition in Hamburg
More photovoltaics
HEnW KommunalEnergie GmbH was founded in 2024 to come up with and operate climate-friendly energy solutions. It currently operates 35 systems with an output of 1.9 megawatt peak. Another 31 systems with 3.2 megawatt peak are under construction or in the commissioning phase. "We are planning four megawatt peaks for this year," said Michael Prinz, Managing Director of Hamburger Energiewerke. The company is also planning plants with a capacity of five megawatt peak for 2025.
Climate-neutral supply by 2045
Hamburg is aiming for a climate-neutral electricity supply by 2045. "We are rolling up our sleeves in public buildings and have installed PV systems on roofs of schools and swimming pools among others," said Jens Kerstan, Senator for the Environment. The University of Hamburg wishes to set up even more roof-top photovoltaic systems in future and to use the sustainably-produced electricity, according to Martin Hecht, Chancellor of the University of Hamburg.
