Storage power
Storage power in the SpeicherCampus context: determines how strongly the system can intervene during load peaks. Technically, the term is usually described as power in kW or MW.
What does storage power mean?
Storage power — stated in kW or MW — summarizes how much power a system can absorb and deliver. Alongside capacity it is the second fundamental quantity of any storage system, limited jointly by the PCS, the battery’s C-rate and temperature.
In sales practice, power often disappears behind capacity marketing: the kWh figure gets advertised, but for peak shaving, backup power and charging infrastructure the kW figure is almost always what decides.
What matters in practice
- determine the governing power requirement for each application
- distinguish continuous power, short-term power and temperature derating
- match the power-to-capacity ratio (C-rate) to the application
- scaling: parallel connection increases power linearly
Practical example
A charging hub needs 400 kW of buffering power but only 300 kWh of energy per peak hour. The choice falls on high-power units with a 1P rate instead of large, sluggish capacity blocks — power was the scarce resource here.
The SpeicherCampus perspective
SpeicherCampus treats storage power as an independent design goal. In the product finder it is the central filter dimension alongside capacity.
