From load to node
In Zhaoyuan City, vehicle to grid turns the charger from a pure consumer into a storage node. Cars charging in valleys and sending back at peaks flatten grid load and may bring owners earnings for the energy they lend to the system.
Avoid a second retrofit
New charging facilities without two way ability may soon face forced upgrades. Planning bidirectional capability now spares Zhaoyuan City the cost of rebuilding later when rules and incentives finally catch up to the available technology.
Clear responsibility first
Write site duty, supply responsibility and settlement into agreements before build. Dongdian Huichong keeps local teams in Zhaoyuan City to support the transition, and the sensible move is a small demonstration with clear settlement rules first.
For Zhaoyuan City the path is to pilot before mandating, because a small demonstration with honest settlement teaches more than a district wide rule that outruns both the technology and the settled habits of ordinary car owners.
