China mandates cross-province emergency power sharing — grid operators must now move electricity across borders on demand

China's energy regulator just issued binding rules for how electricity gets moved between provinces during emergencies or shortages. Previously, provinces could hoard power or negotiate ad-hoc deals; now grid operators must follow a standardized protocol to shift supply where it's needed most, with clear authority lines and procedures.

For decades, China's electricity system was built around provincial self-sufficiency — each region generated what it needed, and cross-border trades were rare and negotiated case-by-case. This mandate flips that: the grid operator now has explicit authority to move power across provincial lines without waiting for local permission, which means a shortage in one region can be solved by surplus in another in hours instead of weeks. The structural shift is from provincial autonomy to national grid optimization. This matters because China is adding massive amounts of renewable capacity (solar and wind) that are geographically scattered — some provinces will have huge surpluses, others will have deficits. Without forced sharing rules, you get blackouts in some places and curtailment in others. With them, you get a functioning national grid.
