Your entire bus fleet plugs in at the same hour. The depot connection cannot take it.
Electric bus fleets all charge in the same overnight window, and that simultaneous peak sets a punishing tariff the depot’s grid connection was never built to carry.
One window, one enormous peak.
A transit operator electrifies the fleet to cut emissions and fuel cost, then discovers the real bill is the depot. Dozens of buses charging together in the small hours create a coincident demand spike that sets the capacity tariff for a period, and the existing connection cannot grow fast enough to carry it. Reinforcement is slow, expensive, and outside the operator’s control.
Charge steady, draw smart.
On-site storage charges gently across the day and discharges into the depot at the overnight peak, capping the demand the tariff is based on while keeping every bus on schedule. It lets an operator add vehicles without waiting years for a grid upgrade, and it shields the depot from time-of-use price swings.
Why 247 Energy.
Depot charging is deep, daily and relentless, which is exactly where supercapacitor storage holds up: hundreds of thousands of cycles without fade, high power on demand, and instant response, all running quietly and without fire risk beside a working garage. Electrify the timetable, not the tariff.
