ChartJavascript is required to render chart Electricity prices: Day-ahead baseload contracts – monthly average (GB).Source: ICIS.Information correct as of: March 2019 This chart shows the price of electricity on the wholesale market in GB for delivery the next working day at a constant ‘baseload’ rate. The data is averaged by month rather than by day and covers around an eight year time period. Further information on wholesale prices can be found in our Wholesale Energy Markets in 2016 report. The data comes from ICIS’s price assessment of over-the-counter trading through brokers. A full explanation of ICIS’s methodology is available on ICIS's website.

This is because gas-fired generation is often the marginal source of supply and hence sets the electricity price. Changes in carbon prices have also influenced electricity prices in recent years. Relevance and further information Day-ahead prices are a good indicator of the short-term price of electricity in GB. However, Day-ahead prices are just one measure of the price of electricity. Suppliers will often buy most of their electricity months or even years in advance of when it will be delivered, so Day-ahead prices may not necessarily reflect the price that suppliers will have paid for their electricity. The ‘baseload’ rate refers to a contract for electricity that is produced continually throughout the day and is distinct from ‘peak rates’ when electricity is bought/sold for consumption at peak times (7am to 7pm).
