Extremely-low gas-fired energy technology, falling demand, and the restart of photo voltaic technology build-out characterised Britain’s electrical energy market within the second quarter this yr, in accordance with a brand new report by vitality information analyst Montel Analytics.
Gasoline output decreased by over a 3rd on this interval to 13.4TWh – the bottom quarterly determine recorded by Montel Analytics within the final 20 years. Gasoline costs rose steadily, beginning the quarter at £23.24/MWh, dipping to a low of £21.26/MWh in early April, then climbing above £23.00/MWh for many of the month. After a quick decline for a couple of days from Could 10 as a consequence of a heat spell, costs surged to a peak of £30.06/MWh on June 3 and remained above £26.00/MWh for the remainder of the quarter, closing at £27.35/MWh.
Common transmission system demand dipped to 23.5GW, the bottom determine for any Q2 because the first lockdown in 2020. This was attributed partly to milder climate, notably in Could and late June and elevated embedded technology from photo voltaic and cargo shifting from batteries and different sources.
Renewables contributed 47% to the GB energy technology combine, with wind output (17.2TWh), biomass (6.8TWh), and hydro (1.1TWh) all boosting Britain’s clear vitality output through the quarter. Photo voltaic technology reached its highest stage for any latest quarter, rising from 4.90TWh in Q2 final yr to five.1TWh.
Total GB energy technology (excluding imports) fell 17% from the earlier quarter to 54.6TWh, marking the bottom quarterly complete since Q2 2022. This discount was attributable to decreased demand and excessive ranges of imports, which resulted within the steep drop in output from CCGT crops.
Internet imports into GB rose to 9.2TWh from 7.4TWh the earlier quarter, with many of the energy coming from France (6.4TWh).
Phil Hewitt, director at Montel Analytics – which is a part of the Montel group – mentioned:
“Photo voltaic technology rose by 4% on Q2 final yr, which is decrease than the earlier year-on-year development in Q2 2023 however that is within the context of some fairly horrible climate. The sample of demand destruction additionally continued due partly to hotter climate and folks and companies turning into extra aware of limiting their vitality prices.
“Increased ranges of web imports resulted in very low fuel output, whereas fuel costs elevated steadily following a decline within the earlier quarter. This rise was pushed by a number of components together with escalating tensions within the Center East affecting liquid nitrogen fuel (LNG) shipments, an earlier-than-expected cease in Russian fuel flows to Austria, and decreased provides from Norway as a consequence of upkeep at manufacturing services.
“Wind output fell from 24.9TWh within the first quarter to 17.2TWh in quarter two. Reductions in wind technology grew to become needed throughout windy spells, with bid volumes getting used to cut back the surplus of obtainable wind technology. Many of the accepted bids occurred through the first three weeks in April and the best day by day bid quantity for the quarter of greater than 4GW was noticed on the morning of June 28 when wind was considerably excessive.
“The nuclear fleet principally operated at capability on this quarter because of the return to service of most items, with solely restricted outages noticed in comparison with the earlier quarter. Consequently, technology elevated by 37% on a quarter-on-quarter foundation to 10.7TWh, the best for any quarter since Q3 2022.
“In the meantime, coal-fired technology fell to 0.3TWh from 1.0TWh in Q1 2024. This decline aligns with the decommissioning of the final coal-fired energy station, Ratcliffe-on-Soar, which is scheduled to shut on September 30 this yr.”
Renewables technology (wind, biomass, photo voltaic, and hydro) was the most important contributor to the GB energy technology combine throughout Q2 2024, accounting for 47% of the full output. Gasoline-fired technology made up 21% of the full, with nuclear (17%), imports (14%), and coal (0.3%) accounting for the remaining.
