Firm Frequency Response

Dynamic demand management

Real-time responses

What is Firm Frequency Response?

Firm Frequency Response is split into 2 types of programme: Dynamic Frequency Response (DFR) and Static Frequency Response (SFR).

DFR is known as a pre-fault programme, as it acts as a preventative measure. SFR is known as a post-fault programme, as it reacts to a frequency trigger being hit.

In order to connect to the most lucrative dynamic programme, sites rely on complex controls, and should be managed by a sophisticated technology platform, such as GridBeyond’s, to provide the most valuable service.

The more complex the response, the more sophisticated the technology

As renewable generation plays a larger part in our energy landscape, and as frequency balance wavers when a generation source fails, the quicker the response, the more quickly the grid can be stabilised.

This sub-millisecond response requires the most sophisticated of technology, due to the complexity of the management of the asset’s capabilities. This is why National Grid are willing to pay more for these services.
