“Storing with wind and foresight”: increasing the degree of self-sufficiency of the city of Haren
The city of Haren (Ems) has set itself the goal of increasing the city’s energy self-sufficiency from local renewable energies to up to 80%. In this project, two INTILION | scalecube large-scale storage units are being used as a containerised version – coupled to an electrolyser and the wind farm. Storing the energy means that green electricity can be supplied at any time, even during periods of low production, which significantly increases self-consumption for the city of Haren.

- Self consumption
- Trading
- E-mobility
A look at the initial situation: the "Full supply from RE" project
Back in 2014, the town of Haren (Ems) was proud to report that 45% of its quarter-hourly intervals came from renewable sources. In an effort to further increase this proportion and maximise self-sufficiency, the Haren Green H2 Hub was built, which is supplied with electricity from the local Fehndorf/Lindloh community wind park. In order to stabilise the volatile energy, the integration of a battery storage system was planned from the outset. A 2 MW electrolyser was also installed at the H2 hub in Haren, which is connected to the wind farm and the battery storage system via a higher-level energy management system. The storage units ensure the stabilisation of surplus electricity, i.e. the production volume from wind energy that exceeds demand. The town of Haren is thus consistently focussing on a sustainable energy future and setting standards for the responsible use of renewable resources.

The customised solution for the project
A battery storage system proved to be an indispensable component for the successful realisation of this project in order to optimally utilise the volatile energy generated by the wind farm. We installed a large INTILION | scalecube storage system in two 40-foot containers with a nominal capacity of 7.4 MWh. We not only supplied and installed the batteries, but also integrated the control units, converters, transformers and switchgear. We were also responsible for the smooth installation and commissioning of the entire system. The volatile energy generated by the wind farm can now be stored efficiently and distributed in a targeted manner. The seamless integration of this advanced energy storage system into the overall concept of the project is helping to support the town of Haren on its way to a sustainable and environmentally friendly energy future.

Strong partnerships as the key to success
The success of this project was the result of committed cooperation between numerous contractors. The smooth realisation of the project depended to a large extent on coordination with our project team. Together, we mastered the challenges and utilised our diverse expertise to ensure the harmonious integration of the various components. In the end, we can proudly announce that the project was successfully realised.
On behalf of CEC Haren, I would like to thank you for the excellent and constructive cooperation in this ideal demonstration project, which shows how the energy transition can work in the future, especially in rural areas.
