Good neighbourliness

Current news: In January 2026, Hamburger Energienetze and the Borough of Altona will begin construction work in Lise-Meitner-Park. New power lines must be laid to supply the surrounding district as well as DESY. This work is not directly related to our planned PETRA IV project, which has not yet been approved by the federal government. We anticipate the federal government's decision on PETRA IV in the first half of 2026.

The power lines supplying the district and DESY need to be replaced due to their age. Replacing them now brings a major advantage for the possible future construction work for DESY’s future project PETRA IV: Once the federal government has given the go-ahead, construction work on PETRA IV can begin immediately.

If you are interested in DESY and DESY’s future project PETRA IV, please feel free to come by for a tour. No special knowledge of physics is required. You can register for a tour with us or take a virtual tour. We look forward to welcoming you to our events.

But of course, we would also be happy to come and visit you – at your sports club, your initiative or in your community – to get to exchange ideas. Please feel free to contact us.
