Frequency regulation
Frequency regulation in the SpeicherCampus context: grid-scale storage can react quickly. Technically, the term is usually described as stabilization of the grid frequency.
What does frequency regulation mean?
Grid frequency — 50 Hz in Europe — is the real-time measure of the balance between generation and consumption: surplus pushes it up, deficit pulls it down. Frequency regulation keeps it in a narrow band, classically via power plants, increasingly via battery storage.
Storage is predestined for this because it can switch between charging and discharging in fractions of a second. The capability is marketed on the balancing markets — in practice a domain of grid-scale systems.
What matters in practice
- the relevant market is primary reserve (FCR) with strict prequalification
- frequency services tie up power and capacity permanently
- even grid-connected commercial systems must respond frequency-stably (protection settings)
- participation below the MW class only pooled via aggregators
Practical example
A HyperBlock M project provides 2 MW as primary reserve. The battery reacts to frequency deviations within seconds and is paid for constant readiness — a revenue model that exists only in this size class.
The SpeicherCampus perspective
SpeicherCampus places frequency regulation where it belongs: as a utility-scale application for PotisBank and HyperBlock projects with professional marketing.
