Global GridThe Isle of Man's energy mix and electricity
🇮🇲 In 2023/24 (April 2023 to March 2024), the Isle of Man's power stations made electricity from the sources below; the total amount was not published. Almost all of it, 95%, came from gas. In total, 4.7% came from low-carbon sources (nuclear and renewables) and 95% from fossil fuels.
The dashboard shows the Isle of Man's energy mix and the planned flow on its cable to Great Britain (as notified to Elexon).
Energy mix in 2023/24
- Gas 95%
- Bioenergy 4.1%
- Hydro 0.6%
- Oil and other fossil fuels 0.3%
| Source | Share | Generated |
|---|---|---|
| Gas | 95% | n/a |
| Bioenergy | 4.1% | n/a |
| Hydro | 0.6% | n/a |
| Oil and other fossil fuels | 0.3% | n/a |
About these figures
- Bioenergy here is the Richmond Hill energy-from-waste plant, which burns the island's household waste and makes about 25 GWh of electricity a year (SUEZ). Oil is diesel generators.
- The island uses around 360 GWh of electricity a year (Guide to the Power System of the Isle of Man, March 2025). The total generated in 2023/24 was not published in a source we could check, so it shows as n/a.
- Most of it comes from the gas-fired Pulrose power station (84 MW), with diesel generators (40 MW), the Sulby hydro plant (1.2 MW) and the energy-from-waste plant (5.5 MW) (Manx Utilities and SUEZ, as recorded by Electricity Maps).
- A 104 km undersea cable to Bispham, near Blackpool, has linked the island to Great Britain's grid since 2000; it can carry about 60 MW (Manx Utilities). Manx Utilities says the island is generally a net exporter of electricity over it, and in 2022/23 it exported 37% of the electricity generated on the island (Manx Utilities annual report 2022/23, quoted by Tynwald's research service).
- Gas reaches the island through an 11 km branch of the UK–Ireland gas interconnector, landing at Glen Mooar, since 2003 (Gas Networks Ireland; Global Energy Monitor).
Energy security score
Vulnerable. It is not ranked because its power system is very small. The score shows how well a country could keep electricity affordable and on if fuel supplies were disrupted. It is based on 3 of the 5 measures.
| Measure | Score |
|---|---|
| Produces its own energy No reliable figure exists for the Isle of Man, so this measure is left out and the other four count for more. | n/a |
| Variety of power sources How evenly generation is spread across nine sources. The largest, gas, made 95%. | 11 |
| Little reliance on imported power No import figure is available. | n/a |
| Low-carbon power Nuclear and renewables made 4.7% of generation. | 5 |
| Low gas and oil use Gas and oil made 95% of generation; the score is 100 minus that share. | 5 |
The five measures are weighted 30%, 20%, 20%, 15% and 15%. How the score works.
