China’s renewable power dependency has a major flaw. This transformer just solved it.

by Inside China Business [1-12-2026].

Solar and wind power are crucial to China's power mix, and China builds more renewables power generation than the rest of the world combined.

But their dependency on renewable sources poses a serious problem for grid operators, who struggle to balance the intermittent supply sources hitting the system. That challenge is compounded in China, who have massive wind and solar facilities thousands of kilometers away from the population centers who depend on them to keep the lights on.

Local weather conditions in China's far west regions can have wide-ranging impacts on the national system, and "backflow" issues can cause blackouts anywhere in local markets.

A new high-capacity DC transformer may be the answer in China, and elsewhere in Asia where heavy reliance on renewable power strains electric grids.
