PLMJ advises Helexia on €20M investment in energy storage systems
PLMJ advised Helexia, the French company of the Voltalia group, on the signing of an agreement with NGEN Group for the implementation of energy storage systems in Portugal, involving an investment of €20 million in 2026.
The agreement foresees the development of a pipeline exceeding 100 megawatts (MW), and Helexia expects to complete about a quarter of it (25 MW) during 2026, representing an investment of around €20 million. NGEN Group is a European energy technology company specializing in battery energy storage systems (BESS) and smart grid solutions.
The system is integrated with photovoltaic panels, allowing the battery to be charged whenever there is excess solar production. A behind-the-meter solution consists of a system for energy generation, storage, and management that enables the company to consume the electricity produced internally before drawing from the power grid.
The operation was led by João Marques Mendes, partner responsible for the energy practice at PLMJ, with the participation of senior associate Maria Gorjão Henriques (both pictured from left to right).
