Photovoltaic system installed on the 3U distribution centre in Koblenz

  • Around 300 kWp cover up to 60 % of the electricity consumption
  • Around 132 tonnes of CO2 are saved annually
  • Investment will have amortised within a few years

Marburg and Koblenz, 30. September 2021 – 3U HOLDING AG (ISIN DE0005167902) has built a rooftop photovoltaic (PV) system at its Koblenz site. The distribution centre for 3U online trading, which is operated by the subsidiary PELIA Gebäudesysteme GmbH, has around 14,000 m² of roof space. 810 photovoltaic modules with a nominal output of 299.7 kWp are now installed on a large part of the roof. Five powerful inverters ensure that the electricity generated in the distribution centre can be used by the centre itself and that surpluses can be fed into the grid. Up to 60 % of the annual electricity consumption at the site is covered by the PV system. In this way, the company saves around 132 t of CO2 year after year. The use of self-generated solar power is also cheaper than purchasing it from an electricity provider. The production costs are calculated at less than 6 cents per kilowatt hour. The profitability calculations indicate that the investment of around EUR 250,000 will have paid for itself within about seven years.

Michael Schmidt, Spokesman of the Management Board of 3U HOLDING AG, sees the commissioning as confirmation of this assumption: “Since the first beginnings of our business with renewable energies in 2009/2010, this assumption has been confirmed time and again: Sustainability, ecology and profitability go hand in hand. Our investment in the photovoltaic roof system in Koblenz reduces our carbon footprint considerably and leads to significantly cheaper energy costs. Photovoltaic investments like this help to sustainably increase the value of the company.”

The warehouse and logistics centre in the Koblenz industrial park was built by 3U HOLDING AG with an investment volume of around 12 million euros. The 3U subsidiary PELIA Gebäudesysteme GmbH put it into operation in May 2021 and ships the goods of the Group’s SHK segment (sanitary, heating and air conditioning technology) from here. With its subsidiaries in the SHAC segment, in particular with the online trading of Selfio and PELIA, the 3U Group is successfully active in the e-commerce megatrend. The 3U online trade has doubled its sales volume over the last five years. The new distribution centre offers the necessary capacities for the planned further dynamic growth.
