Tesvolt Delivers High-Voltage Storage Systems Around the Globe for 9 Cents

Wittenberg, 04 December 2017 – TESVOLT has begun delivery of the new TS HV 70 generation of high-voltage storage systems, which store energy even more efficiently than before. To enable installers to compare different storage systems reliably and transparently, TESVOLT is also now offering an LCOS calculator on its website. This can be used to calculate and compare the actual costs per kilowatt hour stored (levelized cost of storage, LCOS) – making it the very first online tool to offer such a clear and comprehensive comparison. For TESVOLT’s high-voltage storage systems, the calculator gives an LCOS of 9 to 10 cents per kilowatt hour.

New high-voltage storage system increases cost efficiency

TESVOLT has adjusted various parameters to make its TS HV 70 high-voltage storage system even more efficient and, as a result, even more profitable. The system’s discharge capacity has been boosted to as high as 75 kilowatts, and customers can choose to install 14 or 16 modules. Thanks to its increased capacity, the high-voltage storage system achieves a particularly low LCOS of 9 to 10 cents per kilowatt hour stored.

LCOS calculator brings greater transparency to the storage system market

The abbreviation LCOS stands for levelized cost of storage, which refers to the cost of storing one kilowatt hour in a battery storage system including battery inverter – without taking into account production costs, which are included in the LCOE (levelized cost of energy), for example. This makes the LCOS one of just a few indicators that can be used to reliably compare the profitability of different storage system models.

To enable specialist partners to access this tool, thereby ensuring greater transparency in the storage system market, TESVOLT is now offering the LCOS calculator alongside the storage assistant and the peak load assistant on its website. The relevant information for TESVOLT products is already stored in the tool’s database, while the details of other storage systems can be manually entered using data sheets in order to calculate and compare them.

“We want this comparison with the rest of the market,” says Michael Geib, Vice President of Global Sales at TESVOLT. “Properly dimensioned commercial storage systems  are unbeatable in an LCOS comparison. So we’ve decided to be completely transparent when it comes to profitability. After all, alongside the right size and flexible expansion options, profitability is the most important factor in the decision to invest in a battery storage system.”
