With the change of mix of energy generation, the national grid operator need to continue ensuring a good balance of electricity transmission at any given time. In other words, ensuring that the energy flow remains constant.
One of the solution is the Enhance Frequency Response: The aim of this service is to maintain the system frequency closer to 50 Hz under normal operation.
Speed of response is a key element of EFR. The assets must be able to deliver at 100% EFR capacity for a minimum of 15 minutes under normal operating conditions. For storage assets, this equates to a minimum power to energy ratio of 2C.
EFR is a service to provide frequency response in one second or less.
As a leading provider of storage systems, SMA has the capacity to meet all EFR’s requirements?
FIRM FREQUENCY RESPONSE (FFR) is another tool considered by the National Grid. Its purpose is to maintain frequency around 50 Hz.
Frequency Response (FFR) is the firm provision of dynamic or non-dynamic response to changes in frequency.
This service is open to generators connected to the transmission and distribution networks, storage providers and aggregated demand side response.
