Battery energy storage system (BESS) technology supports the variable generation of renewable energy technologies by playing an important balancing and grid stability role. BESS helps support the network operator by storing energy at times when generation exceeds demand and releasing electricity back to the grid network when demand exceeds generation. 

BESS is essential to enabling and accelerating the rollout of zero carbon energy. Increasing its installed capacity will be vital to support Northern Ireland's net-zero emissions target and help to deliver a reliable, resilient, decarbonised electricity system for the future.

BESS has a key role in cost-effectively decarbonising the power sector. They help to balance the electricity system at a lower cost by maximising the output of variable generation as well as minimising both network upgrades and the need for new infrastructure

The Ballyross BESS proposal includes a comprehensive Landscape Mitigation Plan. The measures within this plan would not only reduce potential visibility of the project but also provide wildlife corridors and vital resources for mammals, birds, and insect species. The plan includes measures for the seeding of areas using a specific wildflower seed mixture to attract the pollinators crucial to a healthy eco-system.

The BESS could deliver direct benefit to the area – generating jobs for local businesses during construction and decommissioning. Inward investment can be significant as a range of services may be required including haulage, on-site welfare facilities, refuse and recycling facilities, transport and local accommodation for construction workers.

RES has been working in the BESS market for a decade and design safe storage projects using proven Lithium iron phosphate technology. RES has developed over 1GW of BESS across the UK and Ireland and currently manage over 600MW of operational storage projects with 24/7/365 monitoring provided from their control centre in Glasgow.
