Enhanced Frequency Response (EFR): Use of Energy Storage to deliver active power to the grid within 500ms as a proportional response to a change in system frequency outside of the deadband. Proportionality of the response means that active power increase/decrease has to be proportional to the frequency deviation from 50Hz.

EFR tender results
Note: (1) Under the EFR tenders participants were invited to submit bids under either ''Service 1'' or ''Service 2''. Service 1 has a deadband of +/- 0.05 Hz compared to Service 2 with a deadband of +/- 0.015 Hz deadband. Whilst the wider deadband Service 1 facilities are cheaper to run, they are less useful to National Grid since they are

EFR was designed "to improve management of system frequency pre-fault" [27]. To be eligible for EFR, a BESS must be able to provide symmetric power response to frequency deviations outside the so-called ''deadband'', 2 and to inject or absorb power at its rated capacity for 15 min uninterrupted. Although penalties for under-delivery exist ...
EFR: what we learned from the first auction
EFR is defined by National Grid as being a service that achieves 100% active power output at 1 second (or less) of registering a frequency deviation. Other frequency response services include Primary and High which have timescales of 10 seconds, and Secondary which has timescales of 30 seconds. Batteries the big winners in the first EFR auction
Implementation of Envelopes as a Regulatory Degree of Freedom …
In Great Britain, the Enhanced Frequency Response (EFR) service was developed considering storage limitations and thus introduces the concept of envelopes to support …
