Advantages of Teiszmann ESS

Provision of positive and negative balancing energy / frequency stability: Both the operators of transmission networks and power plants, as well as private solar energy producers can save excess energy highly efficient in phases of overloaded grids and can feed it back when the conditions are best with respect to the general energy volume and/or the energy prices. In addition, the in-stalled storage volume can contribute to frequency stability in the grid.

Continuous provision of energy from volatile power generation systems: The capability of regenerative energy sources from sun, wind and water rarely meets the contemporary demand. Therefore storage systems are indispensable for balancing generation and demand.

Increase in self-exploiting of regenerative electricity: The installation of small private storage systems allows operators to significantly increase their rate of consumption of self-generated energy. A largely desired effect in this process is that the distribution net-works can be significantly relieved in times of high solarisation rates.

Relief for power transmission networks

Almost every power transmission network has “bottlenecks” due to the limited transmission capacity. However, these are mostly only short-term bottlenecks. Instead of complex network extension, two communicating storage systems can be economically used upstream and downstream of the bottleneck to remove capacity limits.

Peak load reduction

Peak loads are not only a network problem, but in particular a problem which industrial and business enterprises are often facing. If high industrial power is needed only for a short term it makes sense to pro-vide the peak load from storage systems. This ensures that the capacity of the supply network will not be affected to a high extent and the load curve is smoother so that the company will pay a more favourable power supply tariff.

Regenerative mobility

Electro mobility makes sense in particular with regenerative energy production. Shifting of CO2 emissions from the vehicles towards coal-fired power plants cannot be the objective. However, there is often the problem that neither the power nor the time frame of the regenerative energy production corresponds to the loading process. Basic capacities in storage systems used otherwise can be reasonably utilised also in this situation.

High degree of storage efficiency

Storage systems based on modern battery technology can have a storage efficiency of up to 94%. Up to date, this efficiency is not achieved by any other storage medium.

Economic storage costs

Battery systems which are available today allow the provision of competitive energy storage systems. With an optimised storage design the price per delivered kilowatt-hour already dropped to a cost level of only 10-12 cents.

Decentral organisation

Battery storage systems can be set up and installed everywhere where there is demand for storage and/or controlling power range. These are preferably locations of high regenerative production (large-scale PV systems, wind farms), network areas with problematic transmission performance and areas of supply with a high demand for security (hospitals, industrial plants, computer centres etc.).

Scalability/modularity

A key benefit of battery storage systems is that the capacity can be adjusted to the demand at any location in the grid – from private small-scale storage systems in a single-family house (Home Residential Systems – HRS), to medium-size performance categories (Company Storage Systems-CSS) to large-scale storage systems in the MW/MWh range (Megawatt Storage Units – MWSU). The storage capacities can be adjusted and extended in the course of time to ensure optimum storage conditions for any situation.

Security against power failure / isolated operation / black start capability

Due to a very quick switching mode, all storage systems of Teiszmann-Systems AG can be used on-grid as well as off-grid and are therefore fully capable of isolated operation. In addition, the storage capacity can be utilised for the provision of black start capability in the range of network and power stations.

Topography

Battery storage systems are not bound to any topographic requirements and do not impair our natural environment.

Reactive power compensation

Electricity and voltage are subject to phase shifting depending on the connected consumers (inductive, capacitive or ohm resistive load). This results in unnecessary load of the consumer, both physically and economically.
