Work has started on a 14,580-panel solar farm inside London Luton Airport's airfield. It could make 11.2 GWh a year, after a year's delay waiting on grid approval.
Construction has started on a solar farm inside London Luton Airport’s airfield. It will have 14,580 panels and cover 106,000 square metres, roughly the area of 15 full-size football pitches.
The array is rated at 10.42 megawatts peak and could generate up to 11.2 gigawatt hours of electricity a year. The companies building it expect it to be fully connected in early 2027. The details come from the announcement by Ikigai Energy, one of the two firms delivering it, published on 8 September.
It arrives a year later than the airport originally planned.
What is being built
The panels are going in airside, at the southern end of the airfield, across five separate plots. Airside means inside the secure perimeter, so none of it is on land the public can reach.
The key facts, as Ikigai Energy set them out:
- 14,580 solar modules on a ground-mounted array
- 106,000 square metres across five development areas
- 10.42 MWp of capacity
- up to 11.2 GWh of electricity a year
- about 1,467 tonnes of CO2e saved in the first year
- Ryebridge Construction as principal contractor, with Emtec Energy and Emtec Utility Services
The airport is not paying for the panels up front. Zestec Renewable Energy is developing and financing the scheme, with Ikigai Energy as delivery partner. The airport buys the electricity under a long-term power purchase agreement. The two firms say they won the work through a competitive procurement, and that they previously built a similar 10MWp array at Glasgow Airport.
Marc Wolman, Infrastructure Director at London Luton Airport, said: “Generating clean energy on-site is a major step forward in our decarbonisation journey.”
Why it matters to the airport
Electricity is the airport’s biggest source of its own carbon. Ikigai Energy says it accounts for more than 60% of the airport’s Scope 1 and 2 emissions, the ones produced by its own buildings, vehicles and energy use.
The airport operator’s own 2025 sustainability report shows how much electricity it uses. Its figures, in megawatt hours:
| Year | Electricity used (MWh) |
|---|---|
| 2019 | 19,488 |
| 2024 | 18,564 |
| 2025 | 17,643 |
The solar farm’s maximum of 11.2 GWh is 11,200 MWh. On paper, that equals about 63% of the 17,643 MWh the operator used in 2025. That is our calculation, and it is a ceiling rather than a forecast. Panels produce most in summer and at midday, so not all of the output will line up with when the airport needs power, and neither firm has said how much will be used on site.
A year late
The airport’s target was to supply 25% of airport-used electricity from on-site or near-site renewable generation by 2026. Its 2025 report says that will not happen on time. Its own words: “Following delays in securing UKPN approval, full electrification is now expected in early 2027.”
UKPN is UK Power Networks, which runs the local electricity grid. A generator this size needs its permission to connect. The report says the airport spent 2025 advancing the design and completing “key preparatory works and surveys” while it waited.
The solar farm is also part of the airport’s wider Net Zero 2040 aim for the emissions it controls directly.
What it means for you
For most people in Luton, very little changes day to day. The panels sit inside the airport’s secure perimeter, and neither firm has announced any road or footpath closures for the work. Zestec’s chief executive, Simon Booth, said: “Airside solar is a genuinely complex undertaking.”
If you follow the airport’s expansion, this is one of the few parts of its carbon plan with a date and a physical scheme behind it. The bigger question, emissions from the flights themselves, is not touched by it: those sit outside the Scope 1 and 2 figures above.
