NESO's Electricity National Control Centre has this evening
issued an Electricity Margin Notice (EMN) https://bmrs.elexon.co.uk/
for the period 06:00-11:00 tomorrow (9 November).
A NESO spokesperson said:
"We have issued an Electricity Margin Notice for tomorrow
morning, as a routine and precautionary measure, giving market
participants the opportunity to make additional generation
capacity available. This is not a warning of power cuts, there is
no risk to customer electricity supplies, and customers do not
need to take action - Great Britain's electricity system remains
secure."
Background
- Before reporting this story, it is important to understand
what an Electricity Margin Notice (EMN) is and what it is not.
- An EMN is a routine operational market notice used by NESO's
control room as part of the normal operation of Great Britain's
electricity system. It is used to notify the market that
additional generation capacity may be required and to encourage
market participants to make any available capacity known.
- An EMN does not mean forecast electricity demand cannot be
met. It is a routine market mechanism used to further increase
the cushion between expected demand and available electricity
supplies.
- It would be wrong to frame the notice as evidence that
Britain does not have enough electricity to meet demand. It is
not a warning of power cuts and does not mean electricity
supplies are at risk.
- It would also be wrong to describe this as a plea for power
because Britain is not running short of electricity. Customer
supplies are not at risk. NESO is acting in advance by using a
routine market mechanism to maintain an appropriate operating
margin while wind levels are low.
- The EMN is one of a number of operational actions being taken
by NESO. Additional commercial and operational measures are
already being used to manage system conditions and maintain
security of supply.
- Any suggestion that Britain is running out of power, that the
electricity system is struggling to cope, or that customers face
an imminent risk of power cuts would be wrong. Britain's
electricity system remains secure and resilient.
- This notice is directed at electricity market participants,
not the public. Customers do not need to take any action.
