Classic multi-use applications typically allow the combination of two functions in a storage system, such as self-consumption optimization and peak shaving. With the TESVOLT EMS , users can combine multiple applications, even with time-dependent configurations. This opens up entirely new possibilities for optimizing the use of storage systems. It also enables adaptation to regulatory and economic market changes and the realization of business models that may only become relevant in the future.
The matrix illustrates the versatile combination options of operational strategies:

Combining the self-consumption optimisation and peak shaving applications reduces additional costs for peak loads as well as the electricity purchased from the supplier.
Every day, the TESVOLT Energy Manager ensures an optimal charging and consumption strategy. This is based on weather forecast data and the battery capacity or charging level. In many cases, the grid connection specifies a maximum load peak that the TESVOLT system precisely adheres to with physical PS. The difference between this and the maximum storage capacity can be used for self-consumption optimisation. This applies regardless of whether physical PS or the more efficient, dynamic Peak shaving RLPM (registered load profile measurement) is applied.
If the self-consumption optimisation and time of use applications are combined, both the use of electricity produced in-house and any drawing of electricity from the utility grid are automatically aligned to ensure optimum cost efficiency.
The TESVOLT Energy Manager is configured so the amount of electricity that has to be purchased from the supplier in addition to the electricity you’ve produced in-house is charged at a particularly affordable price, e.g. at the night tariff. The battery storage system delivers its power either if and from the point that the company’s own electricity production is insufficient to cover demand, or at certain times when the supplier’s electricity price is particularly high.
Combining peak shaving and time of use applications reduces additional costs caused by load peaks and ensures that electricity is only purchased from the utility grid at times when prices are favourable. (Depending on the pricing of the electricity tariff and potential legal restrictions on the time-dependent maximum amount of electricity purchased.)
The TESVOLT Energy Manager is configured so the storage capacity required for peak shaving is obtained from particularly cheap electricity. The load curve shows how many kWh are typically used for PS and when, so the system knows when the storage system is to be charged and to what level. At predefined times, the storage system can then be charged with cheap electricity from the utility grid.
