Gorona del Viento El Hierro

What Gorona del Viento El Hierro does

Gorona del Viento El Hierro, S.A., founded in 2004 and headquartered in Valverde (El Hierro, Canary Islands, Spain), is the owner-operator of the Central Hidroeólica — a wind-pumped hydroelectric power station that has supplied El Hierro island's ~11,000 residents with renewable electricity since commercial operation began in August 2015. The core system combines a wind farm, a 6 MW pumped storage facility (with 2×1,500 kW and 6×500 kW pump groups), dual reservoirs at 700 m and 50 m above sea level (380,000 m³ upper, 150,000 m³ lower), and an 11.32 MW hydroelectric plant (4×2,830 kW groups, 2.0 m³/s flow, 655 m gross head), with diesel generators reserved as backup for exceptional shortfalls. The system has logged 4,800+ hours at 100% renewable supply since 2015, including a 24-consecutive-day record, and avoided 21,551 tonnes of CO2 and 5,591 tonnes of diesel consumption in 2025. Revenue is generated by selling electricity into Spain's regulated electricity market at tariffs set under Spanish law, supplemented by public services such as a network of 7+ (expanding to 16+) free EV charging stations and energy-efficiency advisory services delivered through the OSIA office (launched 2020). Ownership is majority public (~66% Cabildo de El Hierro, ~3.23% Gobierno de Canarias, plus 7.74% Instituto Tecnológico de Canarias), with Endesa holding 23.21% as a strategic technology partner; the predominantly public shareholder base means profits flow back to the island through dividends (€3.5M distributed for 2021, of which €2.3M went to the Cabildo). Customers are essentially the entire El Hierro population, the Cabildo as majority shareholder/dividend recipient, EV owners using the public charging network, and visiting international delegations studying the model for replication.

Broad incumbents

• Engie: French global utility with significant renewables, hydro, and storage operations in Europe, Latin America, and Africa. Comparable as a multinational incumbent deploying hybrid renewable-plus-storage projects in island and remote territories, including consulting and engineering services similar to Gorona's OSIA advisory office.
• Iberdrola: Spain's largest renewable-heavy utility with substantial hydroelectric and wind portfolios in Spain and globally. Comparable as a domestic incumbent that combines large-scale hydro with wind generation and operates under Spanish regulated market structures similar to Gorona.
• Endesa: Major Spanish integrated utility and 23.21% strategic technology shareholder of Gorona. Endesa operates generation, distribution, and renewables across Spain, providing a direct comparison for how a large incumbent manages grid-connected renewable assets, and is the most natural peer given the explicit partnership and overlap in wind-hydro operations.
• Acciona Energía: Pure-play Spanish renewables operator with significant wind and hydropower assets worldwide. Comparable as a Spanish-listed renewable operator active in wind generation and emerging storage integration, offering a benchmark for project economics and growth in adjacent geographies.
• Enel Green Power: Global renewables arm of Enel operating wind, solar, hydro, and storage across Europe, the Americas, and Africa. Comparable as a large incumbent executing island and remote-territory renewable projects with hybrid generation-plus-storage configurations similar in concept to Gorona's wind-pumped hydro system.
• Vattenfall: Swedish state-owned utility with a major hydro and wind portfolio across Northern Europe. Comparable as a state-affiliated, hydro-heavy operator that combines reservoir storage with wind generation — a similar architectural pattern to Gorona's wind-pumped hydro design.
• Statkraft: Norwegian state-owned hydropower operator and Europe's largest generator of renewable energy. Comparable as a hydro-centric utility with substantial pumped-storage expertise, providing a reference point for the long-term operating economics of pumped hydro and reservoir-based generation.

Direct peers

• Hydro Tasmania: Australian state-owned hydro operator that runs the King Island Renewable Energy Integration Project — a hybrid wind-plus-storage microgrid serving an isolated island community. The closest functional analogue to Gorona in combining wind, storage, and diesel backup for full island supply.
• Hawaiian Electric Industries: US island utility serving Hawaii's isolated grids with high renewable penetration targets and diesel backup for intermittency. Comparable as an island utility operating isolated microgrids where wind, solar, and storage replace imported fossil fuels under a regulated framework.

Others

• Mitsubishi Heavy Industries: Major supplier of pumped-storage hydro turbines and grid-scale power equipment globally. Comparable as the underlying equipment and engineering ecosystem that enables first-of-a-kind pumped hydro systems like Gorona's, and as a potential partner for the company's planned solar and storage expansions.
