Common Misreading and Metrics
A frequent mistake is viewing grid regulation in isolation, because coordination with the whole system decides the outcome. Utilization and coordination efficiency beat installed capacity, and written terms beat verbal promises, since many plans stall at demo for lack of real landing.
Stage-by-Stage Focus
Early stage tests feasibility, rollout tests stability, maturity tests efficiency. In Yantai's varied conditions, adjust the approach by stage and review at each transition rather than using one measure throughout, because what works in one district may not in another.
Is It Worth It
There is no one answer, because it depends on usage frequency and cycle. We suggest a three-year view over upfront cost, counting maintenance, energy and risk, and offer on-site measurement so the math stays transparent and decisions stay simple for partners.
