Omexom Portugal implements energy storage systems in solar project
Omexom Portugal deploys energy storage systems in Hyperion solar projects, strengthening grid resilience.
Omexom Portugal is deploying two Battery Energy Storage Systems (BESS), integrated into the Vale de Moura (29 MWp) and Estremoz (52 MWp) photovoltaic power plants developed by Hyperion Renewables.
With a combined injection capacity of 16 MW and a total storage capacity of 64 MWh, these systems store electricity produced during periods of high solar generation and release it when demand is higher, enhancing the flexibility, stability and efficiency of Portugal’s electricity grid.
Portugal is at a decisive stage of its energy transition, with more than 6 GW of installed photovoltaic capacity. At certain times, high solar output combined with lower demand has led to curtailment. Large-scale energy storage therefore emerges as a strategic solution to turn renewable surpluses into value for the power system.
Under the Balance of Plant contracts signed with Hyperion, Omexom Portugal is responsible for the design, technical integration, partial supply and construction of the infrastructures associated with the storage systems. The technological solution includes 21 battery containers, grid-forming power conversion systems and advanced energy management solutions.
It should also be noted that the Estremoz solar power plant was built under an EPC contract by Omexom Portugal, reinforcing in-depth technical knowledge of the asset and facilitating the efficient integration of the storage system.
