The international project developer Green Energy 3000 GmbH and TESVOLT AG, one of the innovation and market leaders for commercial and industrial energy storage solutions, are continuing their collaboration with the launch of their fourth joint project. This involves deployment of TESVOLT battery containers in a new solar farm near Braunschweig. The solar farm will supply green electricity to around 5,000 households, while simultaneously reducing the load on the utility grid.
Four solar farms with a total of 18.3 MWh
The fourth joint battery storage system project will see TESVOLT deliver two TPS-E storage containers with a total of 10 MWh of energy and 4 MW of output to Gardessen, near Braunschweig in Lower Saxony. The storage containers are to be connected to a solar farm with an output of 12 MWp. Pairing photovoltaics with a battery storage system helps create a more reliable and climate-friendly energy supply in the region. The project is being funded by the government as part of its innovation tendering scheme1.
TESVOLT and Green Energy 3000 have already launched three similar projects over the past two years: battery storage systems totalling 8.3 MWh have been connected to solar farms in Saxony’s Großschirma, Brandenburg’s Maulbeerwalde and Bavaria’s Schnaittenbach. When combined with the current project, this means that the two partners have added a total of around 18.3 MWh in storage capacity to the utility grid.
The ban on bidirectional charging must be lifted
The battery storage system is not just intended to reduce the load on the utility grid; the energy it stores is also sold via arbitrage transactions, for instance, or via participation in the operating reserve markets.
Philipp Schreiber, project manager for large-scale storage systems at TESVOLT:
“Legislators need to take action to ensure the innovation tender remains an appealing tool for project owners. The current stipulation that battery storage systems are not allowed to store electricity from the grid, i.e. that they cannot run bidirectionally, must be changed as a matter of urgency. This is the only way for the available storage capacity to be used to full effect. This would also add a clear additional incentive for investing in energy storage, as operators would be able to boost their profits by selling their storage capacity. In turn, this would quieten demand from project developers for higher feed-in tariffs.”
A stable supply of green energy
Simon Schandert, TESVOLT’s CTO:
“We’re delighted to be continuing our brilliant partnership with Green Energy 3000. With our expertise in battery storage systems and Green Energy 3000’s project development know-how, we’re jointly contributing to a sustainable energy supply and showing the way toward the energy transition.”
Andreas Renker, CEO at Green Energy 3000:
“We managed to technically optimise the projects through our constructive collaboration with TESVOLT, which continued after the battery storage system had been commissioned. The partnership between Green Energy 3000 and TESVOLT has now proved its worth and delivered a wealth of valuable insights for both parties.”
Durable and specialised in ancillary services
TESVOLT’s TPS-E battery container boasts high energy density in three different container sizes, 100% depth of discharge and a planned lifespan of 30 years. Thanks to TESVOLT’s intelligent battery management system, the TPS-E stabilises the integration of renewable energy sources into the utility grid to enable a reliable supply of clean energy. The system can be adapted to any purpose – self-consumption optimisation, peak shaving, arbitrage trading on spot markets or the provision of operating reserves.

This government tendering model, called “innovation tendering”, aims to improve the grid and system security of the German utility grid through combinations of installations.
