Utility-scaleContainerised BESSMV connection

Utility-scale BESS: containerised storage from design to commissioning

Megawatt-scale battery energy storage systems are now standard equipment for solar plants, grid regulation and large industrial consumers. BST.SOLAR covers the full chain: sizing and design, supply of our manufacturer partners' equipment (CATL, EVE, Sunnic, Sinexcel, Kehua, Delta, ComAp), integration, commissioning and operational support.

Applications

  • Storage next to a solar plant: handling export limits, shifting production, optimising feed-in tariff or market sales.
  • Grid services: frequency regulation and reserve markets, in cooperation with an aggregator.
  • Large industrial sites: peak shaving and reserve at megawatt scale.
  • Plant hybridisation: existing generating units combined with storage.
