Potential UK North Sea electrification projects declined in number by around 60% over the past year, according to the North Sea Transition Authority (NSTA). The regulator currently oversees seven schemes and has revised down its projections for the greenhouse gas savings that electrifying installations could deliver.
The NSTA published its Emissions Monitoring Report 2026 on 13 October 2026. Its assessments found that several Central North Sea platforms were not reasonable candidates for a switch to electricity under current conditions. Grid connection schedules were among the constraints, and technical obstacles also narrowed the list of possible projects.
For existing installations, delays in securing electricity supplies can leave too little operating life to justify the investment. Further setbacks in obtaining consent or preparing infrastructure could restrict delivery. NSTA could reassess projects if their economics, expected power-supply dates or prospects for delivery changed materially.
The report models three outcomes for cumulative greenhouse gas abatement over 2027–2050, expressed in million tonnes of carbon dioxide equivalent (MtCO2e). The high-range case assumes delivery of up to 80% of the projects’ potential benefits and projects savings of up to 6.2 MtCO2e. The mid-range case assumes 10–50% of potential benefits, with savings reaching up to 3.6 MtCO2e. The low-range case combines projects already underway with a maximum 10% share of the remaining potential, yielding up to 0.7 MtCO2e.
The industry aims to cut production emissions by 50% by 2030 and by 90% by 2040, using 2018 as the baseline. NSTA considers the earlier goal attainable on present trends, but says the later target requires additional action. Operators are expected to investigate alternative low-carbon power supplies where full electrification cannot be justified.
NSTA estimates that UK oil and gas production emissions dropped 7% in 2025 relative to 2024, bringing the decline since 2018 to 37%. These figures cover offshore fields, onshore processing terminals and exploration flaring. They mark six successive annual decreases.
For offshore fields specifically, with terminals excluded, NSTA attributes 53% of the 2024–2025 decrease to active measures at installations that continued operating. The balance was associated with installations approaching or reaching the end of production.
NSTA also highlighted projects at individual fields. Serica Energy installed equipment to recover flare gas at Bruce in 2026. Neo Next+ is pursuing a similar scheme at Elgin-Franklin and partial electrification at Culzean.
