Naturgy adds two new battery storage projects in Fuerteventura

These, together with five other projects across Spain, will add an extra 100 MW of capacity.

Naturgy is adding seven new battery‑storage projects to its renewable portfolio, bringing the total number of such installations in Spain to 16, the company announced. The new facilities will contribute an additional 100 MW of power and 359 MWh of storage capacity.

Project locations

• Canary Islands – two sites in Fuerteventura
• Castile and León – San Blas
• Castilla‑La Mancha – Los Pedreros
• Galicia – Troncal and Monte Redondo
• Murcia – Jumilla

The six projects are hybridisations of the group’s renewable plants, while a stand‑alone battery will be directly connected to the grid in Vigo. Several of the plants are already under construction and are expected to start operating in the first months of 2026.

Financing

The seven new storage projects, driven by the group led by Francisco Reynés, have secured €39 million in funding from the first call for innovative energy‑storage project aids, co‑financed with the Feder 21‑27 funds, according to the final resolution proposal published by the Institute for the Diversification and Energy Savings (IDAE).

First battery‑storage installations in Spain

Naturgy, the country’s leading gas company and third‑largest electricity provider, has recently begun construction of its first battery‑storage projects in Spain. These batteries will hybridise the photovoltaic parks of:

• Tabernas I and II (Almería)
• Carpio del Tajo (Toledo)
• La Nava (Ciudad Real)
• El Escobar and Piletas (Las Palmas)

Their commissioning is scheduled for 2026.

Portfolio of a total capacity of 260 MW and 689 MWh

Including the seven newly awarded projects, Naturgy now manages 16 storage installations (development and construction phases) with a combined 260 MW of power and 689 MWh of storage capacity. The total investment in these projects will reach €140 million.

These systems store renewable energy for use during periods of low production, enhancing the flexibility of renewable generation and ensuring its integration into the grid.

National energy outlook

According to the Integrated National Energy and Climate Plan (PNIEC), by 2030 81 % of Spain’s electricity generation will come from renewable sources. This creates a need for flexibility tools to match generation with consumption and to provide firm capacity. In this context, storage is crucial for supply security and quality; the PNIEC foresees the installation of 22.5 GW of storage by 2030. Spain’s 2021 Energy Storage Strategy also highlights stationary batteries as a key element for grid flexibility.

Experience in battery storage

Naturgy already has international experience in battery storage. Through its Global Power Generation (GPG) arm, the group connected its first worldwide battery‑storage installation, the ACT Battery project, to the Australian grid in 2023.

This year, in Australia, Naturgy commissioned Cunderdin, its first large hybrid solar‑plus‑battery project, featuring 128 MW of solar capacity and a 55 MW / 220 MWh storage system.
