The Gas Utilities industry in Europe has been anything but steady recently. The Russia-Ukraine war has rocked the whole supply chain, with Russia tightening its gas supply, Europe hustling to cut its reliance on Russian gas and gas prices shooting up following the initial invasion. Amid unprecedented price increases and threats to the supply of gas into Europe, European governments have been forced to step in to support customers and protect energy supplies. All that aside, the industry remains threatened by a long-term decline in gas consumption and accelerating efforts to transition to renewable sources of energy. Revenue is forecast to climb at a compound annual rate of 1.4% over the five years through 2025, reaching €401.9 billion. This growth is almost solely attributable to a spike in revenue recorded during 2022, which followed a recovery from pandemic-induced lows during 2021, when prices and demand recovered as global economic activity rebounded. Russia’s invasion of Ukraine kicked off a period of significant disruption in energy markets, with a surge in gas prices leading to record revenue and profitability for gas manufacturers while causing substantial losses for gas suppliers. Wholesale prices have eased from record highs as European governments have reduced reliance on Russian gas. At the same time, a drop in demand for gas has also contributed to a revenue contraction since the height of the energy crisis. Revenue is set to decline by 3.9% in 2025. Revenue is forecast to increase at a compound annual rate of 1% to €422.2 billion over the five years through 2030. European markets are set to pursue a green revolution in the coming years, with investment in renewable energy sources gathering pace as European governments strive towards emissions reduction targets. Investment in green alternatives to natural gas is likely to lead to a fall in demand, with plans set out by the European Commission to at least triple solar thermal capacity by 2030, displacing the consumption of nine billion cubic metres of gas annually. Gas prices are set to continue to stabilise in the short term, before falling rapidly as renewable generation capacity rises.

Between 2014 and 2021, the number of customers and sites supplied by British multinational utility company Centrica has been in steady decline. In 2021, roughly *** million customers and sites were supplied gas by Centrica. This was a decrease of over *********** compared to 2014. However, the number of customers at Centrica recorded an increasing trend. Domestic market shares Through its England, Wales, and Scotland serving subsidiary British Gas, Centrica has the largest market share of both the gas and electricity supply in Great Britain. The energy service provider had a share of ** percent of the gas supply market over the last few years. Similarly, British Gas was the leader in the electricity supply market, with a market share of ** percent at the end of 2022. Energy supplier switching in the UK Although the company’s market share and the number of its customers decreased over the past few years because of increased competition in the sector, several small energy suppliers failed in 2021 and 2022 because of the energy crisis. Therefore, the trend in energy supplier switching in the UK was reversed for the first time in decades. In 2022, the number of consumers switching from small and mid-tier suppliers to larger ones surpassed the number of consumers changing to smaller suppliers.

The industry comprises eight Gas Distribution Networks (GDNs) across Great Britain, owned by four companies operating regional monopolies. Gas distributors are heavily regulated through price control frameworks set by Ofgem in the UK and NIAUR in Northern Ireland to protect consumers. Over the five years through 2025-26, gas distributors' revenue is forecast to decline at a compound annual rate of 0.8% to £5.2 billion. A downward trend in natural gas consumption has weighed on allowed revenue in recent years, though the impact of changing consumption trends has been mitigated by constant investment in GDNs to improve efficiency, which has been reflected by price controls. Soaring wholesale gas prices spurred an increase in shrinkage costs in 2021-22, leading to a cut to operating profitability. Price control adjustments allowed gas distributors to recover these cost increases, spurring a jump in revenue and profitability in 2022-23. These costs continued to be recovered in 2023-24, though declining consumption spurred a dip in capacity income, weighing on revenue allowances during the year. Revenue allowances continued to fall in 2024-25, reflecting a reduction in shrinking costs and adjustments made based on Supplier of Last Resort (SoLR) costs. Revenue is set to record renewed growth of 1.6% in 2025-26, supported by revenue true-ups to ensure that deferred revenue from previous periods is settled before moving on to the next price control period. Looking forward, the rising efficiency of GDNs, the rollout of smart meters and the decarbonisation of the energy system will influence gas distributors' revenue. Over the five years through 2030-31, revenue is forecast to climb at a compound annual rate of 1.2% to reach £5.6 billion. Major investment required to decarbonise GDNs, such as innovations to help displace natural gas with biomethane, will necessitate a boost in revenue allowances. Although specific details are yet to be released, Ofgem’s Sector Specific Methodology Decision (SSMD) indicates a potential increase in the allowed cost of equity for RIIO-GD3, boosting revenue and operating profit. Shrinkage costs are expected to decline as gas leak detection systems continue to improve. This is set to ease pressure on operating profit in the coming years.

Natural gas producers are facing turbulent times. Europe has traditionally relied on Russia and Norway as internal sources of natural gas, while countries such as the US, Qatar and Algeria are major sources of imports (although accounting for a much smaller share of overall consumption). Russia’s invasion of Ukraine has shaken up Europe’s natural gas supply structure, with European governments making efforts to reduce their dependence on Russian gas supplies. Revenue is forecast to swell at a compound annual rate of 16.2% to €113.9 billion over the five years through 2025. Revenue expanded in 2021 and 2022 as a sharp hike in natural gas prices and a post-pandemic rise in demand drove an increase in exploration and production activity. Russia’s invasion of Ukraine led to a spike in natural gas prices, with the impacts of reduced demand for gas and a decrease in Russian gas production outweighed by soaring wholesale prices and heightened demand for other natural gas reserves, spurring a jump in revenue. An ongoing reduction in demand for natural gas and easing prices caused revenue to dip in 2023 and 2024. In 2025, revenue is slated to bounce back by 53.3% owing to geopolitical uncertainties, including trade wars and fresh sanctions on Russia, buoying natural gas prices. Revenue is forecast to rise at a compound annual rate of 2.3% over the five years through 2030 to just under €128 billion. The gas market will continue to be shaped by geopolitical tensions into the medium term, with the International Energy Agency expecting natural gas prices to remain high until 2025 as countries continue to shift their supply structure. Following this, natural gas demand and prices are set to fall as Europe continues to expand its renewables capacity.
