Where it fits
Develops and operates grid-scale storage projects - BESS and/or pumped-storage - selling capacity and flexibility services to discoms and the grid operator, distinct from selling raw energy.
Why it matters
Storage integrators are what actually turns intermittent solar/wind output into power the grid can rely on at any hour - the commercial layer tying the whole renewable buildout together.
Where the value pool sits
Storage/flexibility capacity payments are a newer, distinct revenue stream from traditional energy sales, increasingly bid for alongside or bundled with generation in RTC tenders.
