Why it matters

Editorial context

Storage can absorb and release energy to help balance supply and demand. MWh measures stored energy; it must not be added to the MW ratings of generators or data centres.

Questions to follow

Research prompts · not assertions of future events
  • What operating evidence shows its contribution to grid balancing?
  • How will additional storage interact with increasing solar generation?

Location precision

Sakra installation reference. The reported 285 MWh belongs to the whole two-site Banyan–Sakra system, not this point alone.
