Galp has begun construction of two energy storage projects with a total capacity of 74 MW / 147 MWh. This will allow the company, already one of the leading Iberian photovoltaic energy producers, to also become one of the largest renewable electricity storage operators in the Iberian Peninsula, with 79 MW / 158 MWh.

The systems, supplied by Sungrow, will be connected to two of Galp’s largest photovoltaic solar parks, located in Alcoutim (Algarve, Portugal) and Manzanares (Castilla-La Mancha, Spain). These systems will use Sungrow PowerTitan 2.0 batteries and incorporate grid-forming inverters , which contribute to greater grid stability. The batteries will allow excess solar production to be stored during daylight hours and sent to the grid during peak demand, especially at dusk.

“These projects reinforce our commitment to a more sustainable Iberian energy system, combining renewable generation with cutting-edge technological solutions such as storage and smart real-time operation ,” says Georgios Papadimitriou, Galp’s Executive Director responsible for Renewables. ” By creating the capacity to supply clean energy, even during times of peak demand, we are actively promoting a more sustainable, reliable, and affordable electricity system for all ,” he concludes.

In Spain, Galp will install a 14 MW / 28 MWh storage system at the Manzanares photovoltaic park in the Castilla-La Mancha region. In Portugal, the company is developing a total of four storage systems integrated into solar parks, with a combined capacity of 60.5 MW / 120.4 MWh (2-hour batteries). These projects are funded by the Recovery and Resilience Plan through the C21 – REPowerEU Component ( see project profiles ) and represent an expansion of the 5 MW / 20 MWh project, operational since early 2025 in Alcoutim.

Real-time operation from the Galp Control Center

The operation and optimization of these systems is ensured by Galp’s Control Center, approved by the REN and REE in Portugal and Spain, respectively. This team centralizes the real-time management of the photovoltaic plants, storage units, and industrial consumption units, maximizing the value of the energy produced not only for Galp’s portfolio but also for third-party facilities.

By integrating battery systems with grid-forming inverters into an advanced operating model, the Dispatch Center enables Galp to actively participate in grid services markets such as: synthetic inertia, operation of manual and automatic frequency restoration reserves (mFRR and aFRR), and voltage regulation.

This strategic development enables faster grid response, greater system resilience, and lower operating costs for both the electrical system and end consumers.

More solar energy: Galp reaches 1.7 GW of installed capacity

Galp also continues to expand its solar photovoltaic capacity, having completed two new solar parks in Spain. The first, Toledo and Ahín in Castilla-La Mancha, has an installed capacity of 65.4 MWp and an estimated annual production of 127,000 MWh. The second, Almaraz in Extremadura, has a capacity of 49.87 MWp and an annual production of 95,000 MWh.

Together, both plants will produce enough energy to supply approximately 62,000 families and avoid the emission of 23,000 tons of CO₂ annually. With these additions, Galp reaches a total installed capacity of 1.7 GW in solar photovoltaic energy.
