Power plants

⚡ Spain's power plants

Spain has 123.4 GW of capacity in 3,586 operating power plants of more than 1 MW, and another 9.3 GW under construction. Behind them are 141 GW of projects going through the permitting process, more than all the capacity already running, although only part of it will ever be built. This map shows every power plant (operating, under construction, in permitting, announced or already closed) according to Global Energy Monitor's worldwide inventory.

The map

Each circle is a power plant: its area is proportional to capacity and its colour shows the technology. Choose the status, the technologies and the region; hover over a circle to see its details.

3,586 power plants with 123.4 GW for the selected filters.

The coordinates of about 2,900 units (mostly solar and wind farms in the permitting process) are approximate: they are usually placed in the municipality, not on the exact plot. The Canary Islands appear to the south-west: zoom in on the map or choose the region in the filter.

What is running and what is coming

The capacity in permitting and announced is several times the installed capacity, but it is not a forecast: a large share of those projects will never be built (the inventory itself flags as shelved or cancelled those that have had no news for years). Capacity under construction is the best clue to what will come into service in the next two or three years.

How the generation fleet has changed

Capacity that came into service and that was closed each year, according to each unit's commissioning date. You can see the nuclear and coal wave of the 1980s, the combined cycle and wind plants of the 2000s, the standstill of the 2010s and the great solar photovoltaic wave since 2019; and, in the second chart, the closure of almost all coal around 2020.

Beware of 2017: some 790 small photovoltaic farms (3.9 GW, median of 3 MW) are listed in the inventory with 2017 as their commissioning year. This is almost certainly a default date (all of them are farms for which GEM "assumes" photovoltaic technology), and most of them probably date from the first solar boom of 2007-2008. That peak does not reflect what was built in 2017.

Some 8 GW in operation (mostly small solar and wind farms) have no commissioning year in the inventory and do not appear in these charts, so the cumulative total falls somewhat short of current capacity. Repowering projects and plants that closed before the inventory existed may be missing.

Methodology and caveats

• Source: Global Energy Monitor's (GEM) Global Integrated Power Tracker, September 2026 edition, licensed under CC BY 4.0. It is the only open inventory that brings together, for the whole of Spain, the location, capacity, status, owner and dates of every power plant, including those under construction, in permitting or already closed.
• Units and plants: GEM records units or phases (each unit of a thermal plant, each phase of a farm). Here they are grouped by plant and status: if a plant has some units closed and others running, it appears twice, once under each status. The technology of each point is the one with the largest capacity.
• Statuses: operating; under construction (works started); in permitting (pre-construction: with permits or financing in progress); announced; shelved (halted projects, those GEM considers shelved after two years without news, and plants in reserve or mothballed); cancelled (including projects with no news for four years) and retired. In the data and charts they appear with their Spanish labels: En operación, En construcción, En tramitación, Anunciada, Paralizada, Cancelada and Retirada.
• The project pipeline is inflated: some 92 GW of solar and 47 GW of wind are in permitting, far more than the system can absorb and than the PNIEC (Spain's National Integrated Energy and Climate Plan) envisages. Many projects are competing for the same grid access and will end up lapsing. That is why capacity under construction is shown separately from capacity in permitting or announced.
• What is not included: self-consumption and rooftop photovoltaics (about 8-9 GW), small installations (GEM covers solar from ~1 MW and wind from ~6 MW and leaves out mini-hydro and much of industrial cogeneration) and batteries, which the inventory does not include; pumped storage is included, within hydro.
• Comparison with REE: operating capacity by technology is similar to the official Red Eléctrica figures: photovoltaic ~34 GW (REE ~32 GW excluding self-consumption), wind ~31 GW (~32 GW), hydro including pumped storage ~16 GW (~17 GW), combined cycle ~27 GW (~26 GW), nuclear 7.4 GW gross (7.1 GW net). Cogeneration falls well short of the official figure (~1.4 GW versus ~5-6 GW) because GEM only covers the large plants. Pumped storage brings together hydro plants with pumping, pure or mixed.
• Technologies: cogeneration are natural gas units of less than 150 MW that also produce heat for industry; gas turbines and engines and steam turbines are mostly the fuel oil and diesel units in the Canary Islands, the Balearic Islands, Ceuta and Melilla. Municipal waste is counted as non-renewable, and pumped storage, as storage, does not count towards the renewable percentage either.
• Location: the province and region are assigned from each unit's coordinates (offshore wind farms, to the nearest coastal province).
