Frequency Response Services UK

Designed to operate post-fault, i.e.

for deployment after a significant

frequency deviation in order to

meet our most immediate need for

faster-acting frequency response.

First of National Grid ESO new

end-state service (DC-HF/DC-LF)

Dynamic Containment (DC) Dynamic Moderation (DM) Dynamic Regulation

(DR)

A pre-fault service designed to slowly

correct continuous but small deviations in

frequency. The aim is to continually

regulate frequency around the target of

50Hz. New end-state service following

the launch of DC

Rapidly delivers with the aim of

assisting the ESO to keep frequency

within operational limits (Such as due

to an erroneous wind forecast by

responding quickly when frequency

moves towards the edge of the

operational range. ). New end-state

service following the launch of DC

DC Service Specification & Requirement

Dynamic Containment (DC) is designed to:

• Stabilize frequency to within frequency limits (obligation to control system frequency at 50Hz plus or minus 1%. make sure there is

sufficient generation and demand held in readiness to manage all credible circumstances that might result in frequency variations)

• Delivery dynamic response

• Limit response within operation limits

DC Benefits & Needs

• Ensure a stable grid at any

point in time

• Balance supply fluctuations

• Larger total losses (infeed +

RoCoF, outfeed)

Grid network supports: Customers/ESS Off-taker: ESS Suppliers:

• Lighter DOD (Depth of Discharge)

of Battery system

• Better Degradation Curve (SOH)

of Battery system

• Longer Battery System life

• DC service provider &

participation

• Another outstanding revenue

opportunity

• Less burdens to generation

plant assets
