Octave

Flanders Expo in Ghent runs more than 40,000 m² of solar panels and 100 charging points, but its demand peaks sharply during major events, when halls, technical installations, catering, lighting and audiovisual equipment all draw power at once. The venue installed Octave's 5 MWh Battery Container, which stores locally generated energy, manages power peaks on busy event days and makes better use of the available grid capacity. On days without events, the EMS deploys the battery flexibly based on generation, consumption and grid conditions. Installation by ExtraPower / Extravolt, energy supplier BEE (Belgian Eco Energy).

In October 2025, Eneco and football club OH Leuven unveiled a stadium that combines more than 1,000 solar panels with 6 air-cooled Octave One cabinets. The batteries store excess solar energy during the day and release it when demand is high, so the club reduces peak loads, depends less on the grid and uses its own renewable energy instead of importing electricity when prices are high. Eneco acted as energy partner, Octave as battery technology provider, and Extravolt / Extrapower handled the installation.

Family chocolatier Limar, in Turnhout since 1983, aims to make its new factory Belgium's first 100% climate-neutral chocolate plant. It already recovers heat from chocolate cooling and its compressors, and generates part of its own power with 938 kWp of solar panels. To use more of that power on site, Limar installed eight Octave One Air battery systems, with installation and project management by Argona. The Octave EMS runs the batteries fully automatically, based on Limar's energy contract, grid costs, forecast solar production and local consumption.

The Pelkmans-Vervoort family runs a poultry farm with 195,000 chicks in Turnhout, with 230 kWp of solar panels installed in 2022 and 168 kWp more in 2023. An Octave battery system installed by Eco Technics, steered by Yuso on the imbalance market, now maximises self-consumption and sells surplus energy during imbalance peaks. Octave's solar curtailment control scales production down to the farm's needs when prices are negative, so the farm no longer pays to inject. Smart solar curtailment on the imbalance market, added in March 2025, is expected to bring around €5,000 in additional revenue per year (estimate published by Octave).

Hans Gheldof and Leen Vanoverbeke run a mixed farm in Gijverinkhove, West Flanders, with pigs, potatoes and the quinoa sold under Gelvanco in Belgian supermarkets. Early adopters of solar panels more than 15 years ago, they added Octave battery systems spread across three locations within a one-kilometre radius. Team Green handled the installation and project management, and the batteries are steered with Yuso to optimise performance on the imbalance market.

Agricultural company Thovarco has 145 kWp of solar panels, but used to inject about 50% of the solar energy it produced into the grid. With two Octave outdoor battery cabinets installed by Eco Technics and steered for self-consumption and imbalance arbitrage via Yuso, grid injection fell to approximately 10%.
