Why frequency changes
When generation and demand move out of balance, system frequency moves away from its 50 Hz target. Response services ask assets to increase or reduce power automatically to help contain and correct that movement.
FREQUENCY RESPONSE
Fast response when the grid moves away from 50 Hz.
Electricity supply and demand must remain closely balanced. Batteries can change power rapidly, making technically suitable systems useful for frequency response.
Participation normally needs an aggregator or route-to-market provider, compliant controls, metering and successful prequalification.
Dynamic Containment
NESO's post-fault service acts rapidly after a larger frequency event. Batteries may be well suited because they can respond in fractions of a second, subject to technical compliance and available headroom.
Dynamic Moderation and Dynamic Regulation
Dynamic Moderation is designed for faster pre-fault support during volatile periods. Dynamic Regulation provides steadier pre-fault control around normal operating conditions. A provider must decide which service fits the asset and current procurement.
Commercial reality
Service volumes, cleared prices and eligibility change. The optimiser must reserve enough charge and discharge headroom, manage state of charge and avoid conflicts with site operations or other contracted services.
- Technical prequalification
- Telemetry and performance monitoring
- Availability windows
- Stacking and state-of-charge management
PLAIN-ENGLISH FAQ
Questions commercial teams ask.
Can any battery provide frequency response?
No. The battery, controls, metering, response performance and aggregation arrangement must meet the service requirements.
Are frequency-response revenues fixed?
No. Procurement, competition, accepted volumes and clearing prices change over time.
Do businesses contract directly with NESO?
Some larger, capable participants can. Many commercial sites use an aggregator or route-to-market provider to combine assets and manage market operations.
