Long wait to connect large storage systems to the grid, unlike smaller systems<\/h1>\n

Combined power plant consisting of many small commercial storage systems makes the electricity grid more flexible<\/h2>\n

Berlin, Wittenberg\/Germany, 7 July 2025 \u2013 Distribution grid operators are receiving a large number of requests to connect large-scale energy storage systems to the medium- and high-voltage grid. This has been published by Bayernwerk Netz, Bavaria\u2019s largest distribution system operator, and Mitnetz Strom. Due to the necessary grid expansion measures, the waiting period for applicants is usually at least five years. Start-up TESVOLT ENERGY has found a solution that can quickly connect battery storage solutions to the utility grid. It gives commerce and industry \u2013 which usually already have a sufficiently large connection to the low-voltage grid \u2013 the previously lacking incentive to connect smaller energy storage systems of 100 kWh or more to the utility grid.[\/vc_column_text][vc_gallery el_id=”gallery-763710″ medias=”86147″ gutter_size=”3″ media_items=”media|lightbox|original,icon,caption” screen_lg=”1000″ screen_md=”600″ screen_sm=”480″ single_text=”under” single_width=”10″ single_overlay_opacity=”50″ single_padding=”2″ uncode_shortcode_id=”891773″ items=”eyI4NTY5M19pIjp7InNpbmdsZV90ZXh0IjoidW5kZXIiLCJzaW5nbGVfd2lkdGgiOiIxMCJ9fQ==”][vc_column_text uncode_shortcode_id=”187076″]Press images<\/strong>:\u00a0https:\/\/www.tesvolt.com\/en\/press\/long-wait-to-connect-large-storage-systems-to-the-grid-unlike-smaller-systems.html<\/a><\/p>\n

Influx of applications for grid connections from large-scale battery storage systems<\/h3>\n

\u201cThe number of applicants who want to connect large-scale storage systems to the utility grid is continuing to rise. This is no different to the other large distribution system operators,\u201d<\/em> reports Stephan Kilz, Head of Generation Plants for Individual Customers at Mitnetz Strom, one of the largest distribution system operators in eastern Germany. \u201cBringing more flexibility to the utility grid using battery storage systems is important. However, this usually requires grid expansion measures, so it often takes several years before a new large-scale storage system or battery park can be connected to the utility grid.\u201d<\/em><\/p>\n

Bayernwerk Netz, Bavaria\u2019s largest grid operator, is also reporting the very high number of connection requests for large-scale storage systems on its homepage. For the medium- and high-voltage grid, the capacity for grid connections has already been exhausted to such an extent that it will only be possible to connect storage systems of more than 300 kW in five years\u2019 time or more.<\/p>\n

Until now, there has been no incentive for smaller battery storage systems to connect to the utility grid<\/h3>\n

\u201cWe urgently need much more storage capacity in the electricity grid so that renewable energy suppliers do not have to be limited in the event of strong sunlight and strong wind. Instead of building a mind-boggling number of new gas-fired power plants to make the electricity grid more flexible, we should focus on climate-friendly solutions,\u201d<\/em> says Sebastian Kratz, Managing Director of TESVOLT ENERGY. \u201cCommercial and industrial companies have enormous potential for bringing urgently needed flexibility to the utility grid with battery storage systems. So far, other than the big battery park operators, they haven\u2019t had the opportunity to find a good trader that trades their small storage capacities on the exchange. They have therefore been excluded from energy trading.\u201d<\/em><\/p>\n

Network of smaller storage systems makes lucrative energy trading possible<\/h3>\n

TESVOLT ENERGY is enabling commerce and industry to engage in lucrative front-of-the-meter energy trading for the first time. The company integrates battery storage systems of 100 kWh or more into a pool. In doing so, many smaller storage systems form a virtual power plant, whose capacity is traded by renowned traders Enspired, Entrix and The Mobility House. The prerequisite is that commercial enterprises have a grid connection point with an output of at least 50 kW. On-site planning, installation and maintenance of battery storage systems are handled by specialist partners trained and certified by TESVOLT.<\/p>\n

A one-of-a-kind first: trader competition for higher revenue<\/h3>\n

\u201cWe bring our traders into competition with each other. The energy trader whose trades achieve the highest revenues with the least intensive operation of the storage systems gets to manage the most battery systems in our pool,\u201d<\/em> explains Anshoo Pandey, who is heading the new company together with Sebastian Kratz. \u201cThis business model is unique on the market so far. This allows us to generate higher revenues for our customers.\u201d<\/em> Software developed by TESVOLT ENERGY ensures careful operation of the battery storage systems. TESVOLT storage systems that use this software therefore also have a 15-year performance guarantee. This far exceeds the usual market performance guarantees.<\/p>\n

Collaboration with grid operators<\/h3>\n

\u201cWe are also prepared to respond to the requirements of grid operators and operate storage systems in a grid-neutral manner or in a grid-supporting manner at specific times \u2013 i.e. not feeding electricity from the storage systems into the utility grid when renewables are supplying a lot of electricity. Or using our storage systems to absorb excess electricity from the utility grid,\u201d<\/em> says Kratz. \u201cUsing our software and redispatch interface, we can implement this technically straight away and are already talking to grid operators about specific timescales and restrictions for charging and discharging our battery storage systems. After all, we are all driven by the goal of getting as much renewable electricity as possible into the utility grid. Climate protection is not a luxury item that we cannot afford right now. In the current political debate about gas and other fossil fuels, people often ignore that the costs of climate change are enormous.\u201d<\/em><\/p>\n
