The average wholesale electricity price in September 2025 in the United Kingdom is forecast to amount to*******British pounds per megawatt-hour, a decrease from the previous month. A record high was reached in August 2022 when day-ahead baseload contracts averaged ***** British pounds per megawatt-hour. Electricity price stabilization in Europe Electricity prices increased in 2024 compared to the previous year, when prices stabilized after the energy supply shortage. Price spikes were driven by the growing wholesale prices of natural gas and coal worldwide, which are among the main sources of power in the region.

… and in the United Kingdom? The United Kingdom was one of the countries with the highest electricity prices worldwide during the energy crisis. Since then, prices have been stabilizing, almost to pre-energy crisis levels. The use of nuclear, wind, and bioenergy for electricity generation has been increasing recently. The fuel types are an alternative to fossil fuels and are part of the country's power generation plans going into the future.

Residential electricity prices in the United Kingdom amounted to 0.35 U.S. dollars per kilowatt-hour in March 2024, a decrease in electricity prices for households in the UK from the previous year.

Non-domestic consumers with consumption between *** megawatt-hours and ***** megawatt-hours tended to pay higher electricity prices than those users with consumption greater than ****** megawatt-hours. As of 2023, electricity prices for these consumers amounted to ***** pence per kilowatt-hour and ***** pence per kilowatt-hour, respectively. Generally, for both consumption rates, electricity prices presented a trend of growth with a peak in 2023.

In the third quarter of 2025, Bermuda had the highest household electricity prices worldwide, followed by Ireland, Italy, and Germany. At the time, Irish households were charged around 0.44 U.S. dollars per kilowatt-hour, while in Italy, the price stood at 0.42 U.S. dollars per kilowatt-hour. By comparison, in Russia, residents paid almost 10 times less. What is behind electricity prices? Electricity prices vary widely across the world and sometimes even within a country itself, depending on factors like infrastructure, geography, and politically determined taxes and levies. For example, in Denmark, Belgium, and Sweden, taxes constitute a significant portion of residential end-user electricity prices. Reliance on fossil fuel imports Meanwhile, thanks to their great crude oil and natural gas production output, countries like Iran, Qatar, and Russia enjoy some of the cheapest electricity prices in the world. Here, the average household pays less than 0.1 U.S. dollars per kilowatt-hour. In contrast, countries heavily reliant on fossil fuel imports for electricity generation are more vulnerable to market price fluctuations.

Wholesale electricity prices in the United Kingdom hit a record-high in 2022, reaching **** British pence per kilowatt-hour that year. Projections indicate that prices are bound to decrease steadily in the next few years, falling under **** pence per kilowatt-hour by 2030.

File information

The dataset consists of three type of files: - Historic_demand_year_20xx.csv: electricity demand in that year - Historic_demand_year_2009_2024.csv: all the yearly datasets merged in one - Historic_demand_year_2009_2024_noNaN.csv: same as above, but NaN values have been removed and the date includes the hour as opposed to only the day

Columns

The columns in the dataset are: * SETTLEMET_DATA: date in format dd/mm/yyyy * SETTLEMENT_PERIOD: half hourly period for the historic outtunr occurred * ND (National Demand). National Demand is the sum of metered generation, but excludes generation required to meet station load, pump storage pumping and interconnector exports. National Demand is calculated as a sum of generation based on National Grid ESO operational generation metering. Measured in MW. * TSD (Transmission System Demand). Transmission System Demand is equal to the ND plus the additional generation required to meet station load, pump storage pumping and interconnector exports. Measured in MW. * ENGLAND_WALES_DEMAND. England and Wales Demand, as ND above but on an England and Wales basis. Measured in MW. * EMBEDDED_WIND_GENERATION. This is an estimate of the GB wind generation from wind farms which do not have Transmission System metering installed. These wind farms are embedded in the distribution network and invisible to National Grid ESO. Their effect is to suppress the electricity demand during periods of high wind. The true output of these generators is not known so an estimate is provided based on National Grid ESO’s best model. Measured in MW. * EMBEDDED_WIND_CAPACITY. This is National Grid ESO’s best view of the installed embedded wind capacity in GB. This is based on publicly available information compiled from a variety of sources and is not the definitive view. It is consistent with the generation estimate provided above. Measured in MW * EMBEDDED_SOLAR_GENERATION. This is an estimate of the GB solar generation from PV panels. These are embedded in the distribution network and invisible to National Grid ESO. Their effect is to suppress the electricity demand during periods of high radiation. The true output of these generators is not known so an estimate is provided based on National Grid ESO’s best model. Measured in MW. * EMBEDDED_SOLAR_CAPACITY. As embedded wind capacity above, but for solar generation. Measured in MW. * NON_BM_STOR (Non-Balancing Mechanism SHort-Term Operating Reserve). For units that are not included in the ND generator definition. This can be in the form of generation or demand reduction. Measured in MW. * PUMP_STORAGE_PUMPING. The demand due to pumping at hydro pump storage units; the -ve signifies pumping load. * IFA_FLOW (IFA Interconnector Flow). The flow on on the respective interconnector. -ve signifies export power out from GB; +ve signifies import power into GB. Measured in MW. * IFA2_FLOW (IFA Interconnector Flow).

Electricity prices in Europe are expected to remain volatile through 2025, with Italy projected to have some of the highest rates among major European economies. This trend reflects the ongoing challenges in the energy sector, including the transition to renewable sources and the impact of geopolitical events on supply chains. Despite efforts to stabilize the market, prices still have not returned to pre-pandemic levels, such as in countries like Italy, where prices are forecast to reach ****** euros per megawatt hour in September 2025. Natural gas futures shaping electricity costs The electricity market's future trajectory is closely tied to natural gas prices, a key component in power generation. Dutch TTF gas futures, a benchmark for European natural gas prices, are projected to be ***** euros per megawatt hour in July 2025. The reduced output from the Groningen gas field and increased reliance on imports further complicate the pricing landscape, potentially contributing to higher electricity costs in countries like Italy. Regional disparities and global market influences While European electricity prices remain high, significant regional differences persist. For instance, natural gas prices in the United States are expected to be roughly one-third of those in Europe by March 2025, at **** U.S. dollars per million British thermal units. This stark contrast highlights the impact of domestic production capabilities on global natural gas prices. Europe's greater reliance on imports, particularly in the aftermath of geopolitical tensions and the shift away from Russian gas, continues to keep prices elevated compared to more self-sufficient markets. As a result, countries like Italy may face sustained pressure on electricity prices due to their position within the broader European energy market. As of August 2025, electricity prices in Italy have decreased to ****** euros per megawatt hour, reflecting ongoing volatility in the market.
