Inner Mongolia balances renewables and coal

Inner Mongolia is adopting an "all-of-the-above" electricity strategy that increases wind and solar capacity while maintaining and expanding coal-fired generation. Regional officials describe renewables and coal as complementary, with coal plants remaining a key part of the power mix for the foreseeable future.

Authorities state that both renewable and coal capacity will rise for now, with coal used to cover gaps when weather limits wind and solar output. This approach is intended to support grid reliability as large-scale renewable projects come online.

A major example of the region’s renewable buildout is the Dalad Banner solar farm in Inner Mongolia. The facility contains more than 3 million solar panels arranged in the shape of a galloping horse, making it a visually distinctive project as well as a large power producer.

AP reporting indicates that the Dalad Banner farm currently generates around 2 billion kilowatt-hours of electricity each year. This output contributes to the region’s growing renewable share, even as coal remains a significant source of electricity.

Regional officials say coal’s role is being reshaped from primary baseload supply toward supporting and grid-regulating functions. Vice Governor Huang Zhiqiang stated that coal power units have been refurbished so they can ramp down to about 15% of capacity when needed.

This claimed flexibility is presented as a way to integrate more variable wind and solar output without compromising grid stability. As renewable capacity grows, officials say coal power will also continue to expand, but at a gradually slowing pace.

Energy consultant David Fishman noted that in Inner Mongolia, the addition of renewable energy projects has often coincided with expanded coal capacity. This pattern underscores that coal remains closely linked to the region’s broader power development strategy.

Fishman also described the 15% ramp-down capability for coal units as an "aspirational or best-unit" figure rather than an operational norm across the entire fleet. His comments highlight potential differences between technical targets and day-to-day practice in managing coal plants alongside renewables.
