Lanzarote Power Station Gets Green Light for Gas Turbine Upgrade
Lanzarote’s Punta Grande power station has received official authorisation for a technical upgrade intended to extend the working life of one of its gas turbines. The decision was published in the Canary Islands’ official gazette on 9 October 2026 and relates to the existing electricity-generating installation in Arrecife.
For residents, businesses and visitors, the development is part of the ongoing work needed to maintain a reliable electricity supply across Lanzarote and the wider island system.
What has been approved?
The Directorate General for Energy of the Canary Islands Government has authorised Unión Eléctrica de Canarias Generación, S.A.U. to carry out improvements to the plant’s TG1 gas turbine, also identified in the project as Punta Grande 9, Gas 1.
The turbine has a net generating capacity of 19.60 megawatts (MW). The stated aim is to help the generating unit operate reliably over the longer term by renewing key internal equipment.
The project includes replacing the turbine rotor, including compressor blades, changing the casings and replacing the control system. It also includes adjustments to allow synchronisation with the high-voltage network at 66 kilovolts.
Will the upgrade produce more electricity?
The official authorisation is clear on this point: the works do not increase the plant’s electrical or thermal generating capacity, and the turbine will continue to use the same fuel.
This is therefore a refurbishment and life-extension project rather than an expansion of the power station. The distinction matters when discussing Lanzarote energy infrastructure: keeping existing equipment dependable is different from adding new generating capacity.
Why does Punta Grande matter to Lanzarote?
Punta Grande is an established part of Lanzarote’s electricity infrastructure, located in Arrecife. The official documentation describes the wider station as having 11 diesel generating groups and two gas turbines.
Like other island electricity systems, Lanzarote’s grid needs generation that can help meet demand when required. Maintaining existing equipment is one part of keeping the system dependable, while the Canary Islands also work to increase the contribution of renewable energy.
The regional government has described a wider programme to modernise generating units across several islands. It says updated equipment can improve reliability and responsiveness and help the electricity system accommodate more renewable generation. The precise effect of this individual turbine project on bills, emissions or day-to-day supply has not been quantified in the authorisation, so it would be premature to promise specific savings or environmental improvements from this upgrade alone.
Does the project need a new environmental impact assessment?
The published authorisation states that this project is not subject to an environmental impact assessment. The decision treats the work as an upgrade to existing equipment that does not significantly alter the installation’s operating impacts. This should not be confused with a claim that the power station has no environmental impact; it is a statement about the assessment requirements for this particular project.
What happens next?
The authorisation sets a maximum period of 12 months from notification for the operator to apply for permission to put the upgraded installation into service. That is a deadline for the application, not a confirmed date for completion or reopening, and the published decision does not give a precise timetable for the works.
There is also no indication in the authorisation that the project will increase the station’s output or change its fuel. The main purpose remains extending the useful life of the existing TG1 gas turbine.
The bigger picture for Lanzarote energy
The Punta Grande turbine project illustrates the balance facing island electricity systems: existing power equipment must remain dependable while the transition to cleaner energy continues. Modernising an existing unit can help preserve its role in the system, but it is not the same as replacing fossil-fuel generation with renewable power.
Lanzarote’s energy future will depend on a combination of maintaining essential infrastructure, expanding suitable renewable generation and ensuring that the electricity network can manage changing sources of supply.
For now, the confirmed news is straightforward: the Canary Islands Government has authorised technical improvements to the 19.60 MW TG1 gas turbine at Punta Grande in Arrecife, with the aim of extending its useful life. The works are not designed to increase the plant’s capacity or change the fuel it uses.
