Fast charging can create short, high site peaks. Where a tariff bills monthly demand, a battery may cap grid import during those events. The value depends on the exact billing rule and the operator\u2019s ability to recharge without creating a second peak.<\/p>\n\n\n\n

A global battery-cost benchmark cannot replace a local cash-flow model. Charger use, tariff structure, grid upgrade cost and service obligations must be entered separately.<\/p>\n\n\n\n
