Gabonese State signs 25-year PPA with Solen SA for Ayémé solar and battery storage project

The Gabonese State, through a state-owned company, has signed a 25-year Power Purchase Agreement (PPA) with Solen SA for the Ayémé solar and battery storage project. This agreement, announced on March 4, 2026, covers the development, construction, and operation of a 60 MW solar photovoltaic plant co-located with 30 MWh of battery storage. This long-term PPA underscores a strategic commitment by Gabon to integrate significant hybrid renewable energy capacity into its national grid, aiming to enhance energy security and grid stability through the combination of generation and storage assets. This deal is notable for its substantial capacity, combining 60 MW of solar generation with 30 MWh of battery storage, representing a significant hybrid project for the region. The Gabonese State's involvement as the offtaker, backed by a 25-year PPA, provides a strong sovereign guarantee for the project's revenue stream, de-risking the investment for Solen SA, which is responsible for the full project lifecycle. The integration of battery storage alongside solar PV is a critical feature, addressing the intermittency of solar power and ensuring a more reliable electricity supply. While the project value remains undisclosed, the long-term nature and scale of the PPA suggest a substantial investment in Gabon's energy infrastructure.
