Renewable energy sources covered 91% of electricity demand in Navarra in 2025, consolidating the region as one of the European territories with the highest penetration of these technologies in its energy system.
According to data published by Red Eléctrica, electricity demand reached 4,874 GWh, representing a 2% increase compared to the previous year. Meanwhile, total electricity generation in Navarra amounted to 7,007 GWh, growing by 8.2%. In this context, renewable energy sources accounted for 64% of the electricity mix, placing Navarra well above the national average, where these sources cover 59% of demand.
Wind power continues to lead the electricity system
Wind energy remains the main generation technology in Navarra, representing 46.5% of the electricity mix, more than double its share nationwide. In March, this technology played a particularly prominent role, covering nearly 70% of monthly generation and helping renewables reach 88% of the total during that period.
Strong growth in solar photovoltaic energy
Solar photovoltaic energy recorded the highest growth in 2025. Its production increased by nearly 50%, reaching 6.4% of regional electricity generation, two percentage points higher than the previous year. During the year, 183 MW of new installed capacity were added, reflecting the sector’s investment momentum and the strong development potential of this technology in Navarra.
In addition, for the first time, self-consumption data have been published. In 2025, 49 MW of additional capacity were installed, bringing the total to 210 MW. This modality accounted for around 4% of annual generation, anticipating a growing role for distributed generation in Navarra’s energy model.
An industrial and decarbonised electricity system
Industry remains the main electricity consumer, accounting for 60% of demand, followed by the services sector (24%) and residential consumption (16%). This confirms the strong weight of the industrial fabric in Navarra and the importance of ensuring a competitive and sustainable energy supply.
From an environmental perspective, the 4,458 GWh generated from renewable sources avoided the emission of approximately 1.65 million tonnes of CO₂, equivalent to the annual emissions of around 800,000 vehicles.
The high level of renewable penetration strengthens industrial competitiveness, reduces exposure to fossil fuel price volatility and consolidates Navarra’s progress in the energy transition.
At Enercluster, we highlight public–private collaboration and the role of companies within the regional energy ecosystem as key factors in maintaining this leadership and continuing to advance the decarbonisation of industry, mobility and society in the coming years.
