Endesa, through its renewable energy subsidiary Enel Green Power España (EGPE), formally launched the "El Matorral" photovoltaic plant on the grounds of the Barranco de Tirajana Thermal Power Plant this Thursday. It is more than just an inauguration. It represents a paradigm shift for the energy strategy of Spanish island systems and a positive signal for international investors who value resilience in isolated markets. The installation of 9.3 MW of solar power, along with a 10.37 MWh lithium battery storage system—the largest storage capacity in a solar plant in the Canary Islands—directly addresses the main challenge of the energy transition on the islands: the intermittency of renewables.
The integration of batteries is not merely a technological addition; it is a stability insurance. In a non-interconnected electricity system like the Canary Islands, the massive introduction of solar and wind power carries the risk of blackouts or frequency failures. By hybridizing the El Matorral plant, Endesa achieves operational risk mitigation: The storage capacity of 10.37 MWh allows for constant and scheduled energy injection into the grid, stabilizing supply and reducing dependence on traditional thermal plants (which coexist in the same Barranco de Tirajana enclave). This reduces the risk premium inherent in investing in island systems.
The project, with an investment of €11,5 million (of which €5,69 million comes from the EU's Next Generation funds), is an example of how European funds are being channeled to drive the technological transition. For the investor, the co-financing reduces the utility's capital at risk while ensuring critical infrastructure aligned with EU objectives.
The strategy of building the solar plant within the anthropized land of a former thermal power plant maximizes the efficient use of land, a scarce resource on the islands. The implementation (scheduled for early 2026, although the news simulates its inauguration as of October 2025) of this technology in the Canary Islands has a crucial geopolitical impact. It demonstrates Spain's determination to meet its 2040 decarbonization goal in the archipelagos.
With the capacity to supply more than 3.000 homes, 'El Matorral' becomes a symbol of the transition: the sun captured during the day is released at night, allowing the islands to rely less on diesel and more on lithium battery technology, whose development and supply chain become, by extension, a new risk factor and opportunity to monitor in the Atlantic. For Endesa, this project is not only an environmental breakthrough (it will avoid 1.874,5 tons of CO₂ annually); it is the consolidation of its leading role in the restructuring of the Canary Islands energy market, a utility move that ensures its market position in the post-fossil era.
