The Hamburg-based solar power plant developer and operator ENERPARC has integrated large-scale battery storage systems into two more of its ground-mounted solar parks. ENERPARC previously took part in the innovation tender to secure the feed-in tariff with both projects. Both storage systems have now successfully completed the test phase within the deadline.
The battery storage systems have a nominal DC capacity of 17.8 MWh. The 24 battery cubes are each housed in containers developed for this purpose. They enable efficient and reliable storage of the 6.9 MW of solar power generated over approx. 2.5 hours.
The storage units are usually charged at times when solar production is high but demand on the grid is low. This reduces the load on the public electricity grid and prevents the solar power generated from being capped at peak times. The storage systems can then be discharged for roughly the same length of time during periods of high electricity demand, thus also relieving the grid. Depending on the season, they can compensate for the energy requirements of around 2,000-3,500 households.
Armin Scherl, Head of Battery Systems & Innovations at ENERPARC: "We were able to successfully integrate the two large-scale battery storage systems into our solar parks. The storage systems are working smoothly and have already proven their efficiency."
With Büttel and now Lemwerder and Ehndorf, ENERPARC has connected the first three large-scale battery storage systems to solar parks. A further 16 projects are already being planned.
Christoph Koeppen, CEO of ENERPARC, emphasizes: "Batteries are an important driver with which we can further accelerate the energy transition. They stabilize our electricity infrastructure, ensure a flexible green electricity supply in addition to grid expansion and are independent assets for electricity trading. For ENERPARC, large-scale power storage systems are an important addition to the pv plants and are therefore an integral part of our growth strategy."
About ENERPARC:
ENERPARC is an international specialist in solar power plants in the megawatt segment, developing, constructing, operating and investing in large-scale solar power plants. Founded in Hamburg in 2008, the unlisted company now employs over 500 people and, in addition to its core market in Germany, is also active in Spain, France, Portugal, India and Australia. In recent years, ENERPARC has successfully connected more than 650 solar plants worldwide to the grid, with a capacity of over 4,500 MW – around 3,500 MW of which are from its own solar power plants – and has become one of the largest independent solar power producers in Europe. By 2030, ENERPARC's goal is to develop a total of 10 GW of PV plants worldwide for its own portfolio and a further 10 GW for third-party solar portfolios.
