UK Power Prices Soar in First Fortnight of September

Volatile power prices are becoming increasingly prevalent, with extreme increases seen throughout September so far.

A contributing factor to the electricity price hike was a fire at the IFA1 French Interconnector. However, interconnector capacity prices are also peaking at particularly high levels as a consequence of Brexit trading arrangements.

Prices on the day-ahead market for the 14th September peaked at £2,500 per MWh. This is compared to the £40 per MWh average baseload price during 2019-20. This was then followed by another extreme evening peak on the 15th September at a staggering £1,860 per MWh.

The Balancing Mechanism hasn’t been immune from the spikes, as it saw a record high of £4,037.80 per MWh on 9th September.

EnAppSys data shows that in September’s first two weeks, daily average prices have been eight times up on two year ago 2019.
