British Gas is the largest retail electricity supplier in Great Britain. Despite a notable decline throughout the years, it still accounted for ** percent of the market as of December 2024. E.ON followed closely, with a market share of ** percent.  Changes in the Big Six  The electricity market in Great Britain has historically been controlled by a few providers, collectively known as the Big Six. These include British Gas, E.ON, SSE, EDF, Npower, and Scottish Power. However, recently, there have been significant changes in their composition. In January 2020, OVO Energy acquired SSE's electricity and gas distribution business, albeit continuing to sell energy under the SSE brand. Meanwhile, Npower was acquired by E.ON in 2019, turning the Big Six into a de-facto Big Five.  Growing competition in the British electricity supply market  In 2010, the Big Six held *** percent of the domestic electricity supply market in GB. To promote a more competitive market, the British energy regulator, Ofgem, enacted a series of market reforms aimed at increasing access for smaller players. The past decade has seen a significant number of domestic customers switching from large electricity suppliers to small and mid-tier suppliers, causing the Big Six’s market share to dip to ** percent in 2024.

Recent developments include: February 2023: the Crown State in the United Kingdom signed agreements to lease six offshore wind energy projects.

Around 75 % of total investment was expected in renewable energy projects, including offshore wind, hydrogen, and electric mobility., January 2022: SSE announced details of its first solar project that delivered 30 MW of clean energy as part of its ambitious USD 16 billion investment program to power change toward net zero. The 30-MW solar farm at Littleton Pastures is located near Evesham, Worcestershire, England. Once completed in late 2023, the 77-acre site can power about 9,400 homes.. Key drivers for this market are: 4., Supportive Government Policies in the Country4.; Rising Efforts to Decrease the Dependency on Fossil Fuels to Reduce Carbon Emissions. Potential restraints include: 4., Changes in Government Policies Related to Increasing VAT on Various Clean Energy Technologies. Notable trends are: Wind Energy is Expected to Dominate the Market.

In 2024, EDF was the leading company in the wholesale electricity generation market in Great Britain (GB), with a share of ** percent. The UK branch of the German company RWE ranked second that year, with a market share of approximately ** percent.

The selling value of electricity for all sectors in the United Kingdom (UK) has historically been higher compared to the selling value of gas. In 2022, the selling value of electricity totaled 59.8 billion British pounds, while the selling value of gas amounted to 46.8 billion British pounds.

This statistic shows the share of consumers in Great Britain who received information from their energy supplier about the forecast cost of their energy consumption from 2012 to 2017. 58 percent of consumers have not received a forecast of the cost of their energy consumption in the coming year in 2017.

The Electricity Supply industry has developed considerably since its liberalisation in 1999. Following a period in which the Big Six suppliers dominated, energy regulator Ofgem endeavoured to introduce greater competition to the market as part of attempts to drive down energy bills. Major mergers and acquisitions effectively brought the dominance of the former Big Six suppliers to an end at the end of 2019-20. Along with weakening electricity consumption, swelling competition has applied further pressure on revenue in recent years. Electricity suppliers' revenue is slated to climb at a compound annual rate of 4.7% to reach £49.8 billion over the five years through 2024-25. The introduction of the standard variable tariff price cap in January 2019 squeezed revenue growth. The pandemic exacerbated the drop in revenue, as widespread tariff reductions compounded the effects of reduced electricity consumption. With suppliers bound by the energy price cap, soaring wholesale prices led to widening operating losses in 2021-22, albeit with a modest revenue recovery. A renewed spike in wholesale prices led to a continued wave of insolvencies among energy suppliers going into 2022-23, with 31 suppliers falling victim to the energy crisis. Soaring non-domestic energy bills and significant hikes to the SVT price cap spurred significant revenue growth in 2022-23, while the transfer of customer accounts from failed suppliers reinstated the dominance of major suppliers. The introduction of the Energy Price Guarantee (EPG) and support for business energy customers prevented energy prices from spiralling out of control going into 2023-24. A faster-than-anticipated drop in wholesale electricity prices has eased pressure on operating profit in the current year, contributing to an estimated 10.1% revenue contraction. Revenue is forecast to sink at a compound annual rate of 0.9% to £47.6 billion over the five years through 2029-30. Prices will remain elevated in the medium term as concerns surrounding supplies of Russian fossil fuels into Europe inflate wholesale costs. Wholesale prices are set to stabilise in the long term, spurring tariff reductions. The continued drop in electricity consumption is also set to limit growth prospects in the coming years.

The Energy Storage in United Kingdom Market size was valued at USD XX Million in 2023 and is projected to reach USD XXX Million by 2032, exhibiting a CAGR of 21.34 % during the forecasts periods. Energy storage is the process of capturing energy produced at one time for use at a later time, helping to balance supply and demand. It involves converting energy from forms that are difficult to store to more convenient or economical forms. Common energy storage technologies include batteries, pumped hydro storage, flywheels, compressed-air energy storage, and thermal energy storage. These systems store energy in various forms, such as chemical, gravitational, or thermal, and release it when needed. Energy storage is crucial for integrating renewable energy sources like wind and solar into the grid, as it allows excess energy generated during peak production times to be used during periods of high demand. This technology enhances grid stability, reduces reliance on fossil fuels, and supports the transition to a more sustainable energy system. Recent developments include: Jun 2022: Quinbrook Infrastructure Partners acquired exclusive project development rights for the 230 MW/460 MWh battery energy storage project in Wales, United Kingdom. The battery energy storage system will be at the former Uskmouth coal-fired power station in South Wales, which closed in 2015.
