Hamburg Commercial Bank has contributed €75 million to the financing package for NeXtWind.
The bank said the consortium is led by Deutsche Bank, ING, LBBW and others, with the total financing coming in at €1.8 billion.
NeXtWind will invest the funds in the modernisation and repowering of existing wind farms.

Hans Lotzer, head of project finance at Hamburg Commercial Bank, said: “We are proud to support NeXtWind in this groundbreaking transaction, which further advances the expansion of climate-friendly renewable energy infrastructure and underscores our expertise as an experienced financier for the energy transition.”
Jorg-Uwe Fischer, head of structured finance at NeXtWind, said: “This financing is a significant milestone for NeXtWind and a proof to the confidence in our business model.”
He said: “We are delighted that HCOB is supporting us with its experienced team of experts and commitment to the German wind market.”
