French Polynesia: Energy Pool and Sunzil launch their first joint project, carried out for Eco Energy
A partnership driving local energy transition
This project marks the first step of a partnership set to expand quickly, with four more sites to follow in French Polynesia. Sunzil was appointed EPC contractor for this project thanks to its proven capability in complex hybrid projects. The company has also been developing, building and operating solar PV plants for its own portfolio for over 40 years. Energy Pool provides its energy management platform, supervising and optimising all assets in real time. Together, we offer a comprehensive solution perfectly tailored to the needs of island territories.The Tupapa project: maximising solar self-consumption
The end customer of this first project is Eco Energy, a developer and operator of solar power plants in French Polynesia. As the local photovoltaic leader, Eco Energy operates a 15 MWp portfolio made up of rooftops, car park canopies, and solar farms. Its installations are mainly dedicated to self-consumption, with surplus energy fed back into the public grid.In the Punaruu industrial zone in Punaauia, Eco Energy operates several sites, including Tupapa. This site brings together three distinct companies — Sopal, Bevco, and Sodimark — whose rooftops are used to generate the energy required to meet their combined needs, providing a clear illustration of the prosumer model. The project demonstrates how locally generated energy can be directly harnessed for self-consumption. It therefore helps strengthen the sites’ energy autonomy while reducing their carbon footprint.
Beyond complying with the strict injection and withdrawal constraints set by the grid, and the need to continuously maintain the balance between generation and consumption, Eco Energy pursues both economic and environmental objectives. Enhancing its energy autonomy relies on a twofold approach: reducing costs through optimised use of solar and batteries, and lowering its carbon footprint through better utilisation of renewable energy.
Assets managed by an intelligent solution
The Tupapa site brings together several energy assets: two battery storage systems with a total capacity of 5 MWh, three photovoltaic plants with a combined capacity of 2 MWp, as well as industrial consumers such as buildings and refrigerated containers. All of these, subject to strict grid constraints, are connected and managed in real time by Energy Pool’s Energy Management Platform. The platform ensures supervision and dynamic control of the installations, monitors consumption and grid limits, and forecasts energy flows to automatically apply optimised schedules, continuously adjusted to local conditions. This intelligent control maximises solar self-consumption, reduces energy costs and maintains real-time balance with the grid, thus ensuring reliable, efficient and sustainable operation of industrial sites.Results and outlook
The first results are already visible — and impressive. Over 36 consecutive hours, spanning 20, 21 and 22 September, the site achieved 100% self-production highlighting peak operational performance and maximised use of renewable energy, all within strict grid compliance.
