Jackdaw: Will it cut energy bills and how much gas will it provide?

Energy Secretary Miatta Fahnbulleh has stated that gas extracted from the Jackdaw field “won’t lower energy bills this winter.” This view aligns with many energy market analysts who also believe that the increased gas supply from Jackdaw is unlikely to have a notable, direct effect on the energy costs faced by households. The reason behind this is tied to the structure of natural gas markets, as the UK’s energy system is closely integrated with broader European markets. Physical connections via undersea pipelines link Great Britain to the continent, meaning that prices are set based on wider European demand rather than solely on local production levels.

Because British consumers pay prices influenced by the European market, the energy bills for both homes and businesses in the UK are essentially dictated by what customers across Europe are willing to pay. The continent has experienced significant increases in energy prices in recent years, largely driven by geopolitical tensions such as conflicts involving Ukraine and Iran, which have disrupted the supply of gas and oil. Given that the contribution of gas from Jackdaw will be relatively modest, it is unlikely to exert significant downward pressure on the pan-European price, and thus on the bills paid in Britain. Karl Matikonis, professor of taxation at University College Dublin, summed it up by saying, “Essentially, producing more British energy doesn’t necessarily mean cheaper British energy,” adding that North Sea oil and gas are sold at market prices rather than being reserved for British consumers at a reduced rate.

The environmental consequences of the Jackdaw field have also sparked considerable debate. Supporters argue that gas sourced from the UK’s own North Sea would result in lower carbon emissions compared to importing liquefied natural gas (LNG) from the United States. According to the North Sea Transition Authority (NSTA), the total emissions related to the production, transportation, and processing of US LNG are approximately three times greater than those associated with North Sea natural gas. This is largely because the LNG supply chain—including liquefying gas, shipping it across the ocean, and regasifying it at the destination—is highly energy-intensive, leading to higher carbon emissions relative to pipeline deliveries.

However, NSTA also notes that Norwegian North Sea gas, which the UK already imports in significant volumes, has a substantially lower emissions footprint compared to the UK’s existing North Sea production. The main reason for this difference lies in the fact that much of the UK’s gas comes from smaller fields and older infrastructure, whereas Norwegian fields tend to be larger and utilize more advanced technology. The owner of Jackdaw estimates that the emissions intensity of gas production there would be lower than that from older UK facilities, though still higher than emissions from Norwegian fields. Ultimately, the environmental impact of Jackdaw depends on future shifts in UK gas consumption patterns. If Jackdaw’s output replaces American LNG imports, it could reduce the UK’s national emissions. On the other hand, if the new production primarily displaces lower-emission Norwegian imports, overall emissions linked to UK gas consumption could increase
