WILLEMSTAD – On Saturday, September 6, Aqualectra announced that testing of its Battery Energy Storage System (BESS) has been successfully completed in preparation for integration into the island’s electricity grid. With pride, Aqualectra confirmed that all phases of the testing process were completed smoothly. At this stage, the final configuration of the Energy Management System (EMS) is underway, after which the BESS will be formally connected to the grid.

Among the key components tested were the system’s storage capacity of up to 25 MW and 45 MWh, as well as the speed at which the batteries can respond to grid demands when needed. The testing process exceeded all parameters, and no disturbances were reported by customers during the procedures.

For Aqualectra customers, the BESS means a more reliable power supply with fewer outages.

One of Curaçao’s main sources of renewable energy is wind power. However, wind is unpredictable: some days bring strong winds, others very little. As a result, wind energy production fluctuates. The BESS will help stabilize these fluctuations by storing excess energy generated during periods of high wind and releasing it back to the grid when production is low, thereby preventing service interruptions for customers.

This system, together with the new power plant currently under construction, represents significant investments to ensure that Aqualectra’s services remain stable even during peak demand.

The integration of the BESS into Aqualectra’s electricity grid is a clear expression of the company’s mission: to fundamentally serve the community with electricity that is reliable, affordable, and sustainable.
