Tesvolt And WEMAG Announce Commercial Storage System Cooperation
Utility company WEMAG is launching the Germany-wide distribution of Tesvolt commercial storage systems. Tesvolt, the storage system experts from Wittenberg, beat competitors to be chosen as WEMAG’s supplier for large commercial storage systems. These systems make it possible to store the electricity produced by, for example, solar or wind power installations on farms, factories or car showrooms at an average cost of just 9 euro cents per kilowatt hour (kWh).
“Cooperating with Tesvolt will allow us to offer our commercial customers very attractive energy storage solutions. The storage systems enable novel supply concepts, particularly for customers already producing their own renewable energy," explains Michael Hillmann, WEMAG AG’s Sales Director. “The technical solutions and the quality of Tesvolt’s products, as well as their corporate philosophy, were compelling reasons to choose them as our partner."
“Everyone at Tesvolt is delighted to have found such a strong distribution partner in WEMAG. We won’t just be delivering storage systems, we will also be involved in WEMAG’s consulting services," says Sven Huntemann, Area Manager Central/Eastern Germany at Tesvolt. “One of the reasons why WEMAG chose us was the fact that our storage systems provide a technical solution for every application — they’re always the right fit."
The smallest Tesvolt storage system has a capacity of 10 kWh, the largest 1 MWh. Different-sized Tesvolt systems can be combined to suit applications with a storage demand of up to 100 MWh. “Our systems have a high charging speed of 1 C, which is very important for many customers. If, for example, the air conditioning fails in a stable, the animals’ lives depend on the storage system supplying the required energy quickly," says Huntemann.
Thanks to their intelligent battery management system, Tesvolt storage systems can be expanded even years later. “Other storage systems on the market don’t offer this option; expansions are generally only possible within the first year, after which the age difference between the old and new battery cells starts causing problems," explains Huntemann.
Tesvolt storage systems have a service life of up to 30 years, which is the equivalent of around 8,000 complete charge cycles with a depth of discharge (DoD) of 100 percent. At 92 percent, Tesvolt storage systems achieve one of the highest whole-system efficiency ratings found on the market. The systems are produced at the company’s facility in Lutherstadt Wittenberg.
