Net electricity generated by Thermal power plants in the UK declined in 2020

During 2000–2020, installed thermal capacity decreased at a negative low-single digit CAGR. In 2020, within thermal power capacity, gas had the dominant share followed by coal and oil. Gas-based generation is expected to continue dominating installed thermal capacity. The discovery of substantial shale gas reserves is expected to augment the capacity share of gas-fired power plants and reduce import dependence. However, the share of thermal power capacity will decline between 2020 and 2030 owing to government’s decision to phase out of coal-based power generation. From 2020 to 2030, thermal power capacity is expected to grow.

During 2000–2020, annual thermal power generation at a negative mid-single digit CAGR. One of the factors responsible for the gradual decline in thermal power generation is the decline in coal-based power generation. Annual thermal power generation is expected to further decline by 2030.

Generation (GWh) is the amount of net electricity generated in a year from a particular technology/fuel after deducting own consumption. The unit is represented in Gigawatt hours (GWh).

Thermal- All thermal power plants for which the types of turbines or engine used are unknown; are categorized under “thermal” plant type.

Supply Security

The UK is actively involved in power exchanges with several European countries although characterized with a rather unsteady power import pattern over the years. For power generation, the UK generates power from a diverse range of sources, including coal, gas, oil, hydropower, renewables, and nuclear power. Thermal power is its main source of power generation and gas-fired power plants constitute most of its thermal capacity. By the end of 2019, the UK’s proven natural gas reserves amounted to 174 billion cubic meters. However, the UK’s natural gas reserves are decreasing, resulting in a large amount of natural gas imports from Norway, Belgium, and Netherlands. The UK also depends on imports to meet its coal requirements. The dependence on imports represents a potential risk to the security of the energy supply. Hydropower and nuclear power are the other major sources of power generation in the UK and is one of the few European countries not to have opted to phase out nuclear power generation. Hydropower generation in the UK is unreliable and depends on climatic conditions and rainfall. Moreover, the construction of additional hydropower plants has attracted criticism, owing to their harmful impact on the environment.
