Portugal’s Ministry of Energy has announced that it has allocated EUR 100 million ($104.2 million) to 43 energy storage projects which should be installed by the end of 2025.

A total of 79 applications were vying for grant support secured under the country’s Recovery and Resilience Plan (RRP). Eligible projects were in line for up to EUR 30 million and allowed to be developed both at the transmission and distribution levels.

The tender was launched in August 2024 and preliminary results were released last week. The Minister of Environment and Energy, Maria da Graça Carvalho, said on the occasion that the number of applications submitted reflects the success of the scheme.

The addition of at least 500 MW of energy storage projects “will enable significant advances in the decarbonization of the energy system and the transition to a greener economy, aligning with the goals established in the National Energy and Climate Plan 2030. The impact of these measures includes greater security and flexibility of the electricity grid,” the minister said.

The biggest grant was awarded to Solara4Phase4 to the tune of EUR 16.4 million. The second biggest went into the hands of another PV developer, Revendesol, amounting to EUR 14.75 million.

The list of awarded projects includes six developments from Spanish utility Iberdrola, totaling almost EUR 20 million.

Individual project sizes in terms of power output and storage capacity were not specified in the last week’s announcement.

The storage procurement takes place as the nation continues to rapidly grow the share of renewable energy on its grid. In 2024, renewables supplied 71% of Portugal’s electricity, with record production of 36.7 TWh, according to grid operator REN.

Portugal’s updated energy plan targets 80% renewable electricity by 2026 and 85% by 2030.
