Dispatch, not just parking
Yantai Bus Group built the country's first bus-sector virtual power plant, connecting 19 stations and dynamically managing green power consumption for nearly one million yuan in annual benefit. The 293 charging piles are linked to the State Grid e-charging platform and shared with public vehicles.
Idle resources activated
Buses run by day and charge by night, the opposite of residents, so the same piles gain higher utilization through time-sharing. The idea transfers directly to residential communities coordinating with nearby workplace lots, easing the anxiety of finding a charger at home.
Off-peak savings are visible
Off-peak charging saved 6.8 million yuan a year, a model of using valley electricity and avoiding peaks. For Dongshang New Energy and Dongdian Huichong in Yantai, guiding orderly residential slow charging delivers the same logic at smaller scale and steadier cost.
Lesson for communities: The bus case proves local professional operation, off-peak dispatch and open sharing turn charging facilities from cost into asset. The core is unchanged: let professionals do the work and let resources live through off-peak use that benefits everyone.
