The control system for the smaller microgrid will likely cost less in real dollars but consume more of the overall project budget than the control system for the larger one. "Your control system may be a little less [costly] in smaller ones, but it''s going to be a much larger portion of the cost than in the larger one.
On-site battery energy storage systems (BESS) are essential to this strategy. Battery energy storage systems maximize the impact of microgrids using the transformative power of energy storage. By decoupling production and consumption, storage allows consumers to use energy whenever and wherever it is most needed.
