The technical baseline
Electricity substitution has cleared the validation stage. One baseline is to validate in small steps before promotion. The work now is doing it economically and stably rather than proving it can be done at all in a controlled setting.
Learning across regions
Yantai districts and neighbors can borrow from each other. Early movers' lessons often cost more than their successes. We log problems into checklists so later efforts avoid detours, and we sample first before any broad copy of an approach.
How to compare well
Comparison is not about ranking but finding concrete practices to borrow. Writing others' detours down steadies your own road. In varied local conditions, fitting the method to the place matters more than importing a template that worked elsewhere.
What sets electricity substitution apart on site is consistency. Dongshang New Energy shows up, documents the work, and treats each district as a long-term commitment rather than a one-time job. We would rather serve fewer sites well than spread too thin and lose the trust we have built.
