In this weeks’ Current± Price Watch – powered by Enact – we take a look at the use of the coal units, the surge in imbalance price and how National Grid ESO worked to keep the lights on.
National Grid ESO has called on four of its contingency coal units to warm, as well as issuing an electricity margin notice (EMN), as capacity margins for this evening’s peak look tight.
Ofgem has stated it is ready to use its powers to change market rules if necessary in light of balancing costs doubling between September and November.
The volatility in the energy market has continued this week, with National Grid ESO issuing another Electricity Market Notice (EMN) while day ahead prices just to almost £1,500/MWh.
