During the 14th Five-Year Plan (2021-25), Hohhot has developed a stable, efficient, and clean heating system to comprehensively enhance heating services.

In 2023, Hohhot established the longest and most capable long-distance heating network in China, achieving a heating capacity of 20 million square meters from 2023 to 2024, and 60 million sq m from 2024 to 2025. By 2027, with the use of large temperature difference heating technology, this project is expected to reach a heating capacity of over 91 million sq m.

During the five years, Hohhot has implemented an interconnected heating network project to ensure stable heating by allowing other heat sources to quickly supply heat. Coordinated management and mutual support has been realized among the five major cogeneration heat sources – Jinshan power station, Datang Togtoh power station, Jinqiao power station, Shengle Cogen power station, and Hohhot power station – along with large-scale emergency peak-shaving heat sources. In the main urban area, 85 coal-fired boilers have been replaced with clean heat sources, further improving the stability and cleanliness of the heat sources.

In 2024, Hohhot advanced the "Warmth Project", repairing and upgrading 209 kilometers of heating pipelines, 1,333 community courtyard pipelines, and 743 heat exchange stations. A smart heating management service platform was established, installing over 90,000 temperature sensors and upgrading 708 heat exchange stations with smart technology for real-time monitoring and intelligent dispatch of heating data across Hohhot’s heat sources, networks, exchange stations, and users. Hohhot also launched a heating service hotline and formed a professional emergency response team to promptly address users' heating issues. "Heating stewards" were assigned to each community to provide precise services, improving heating quality and customer satisfaction.

Hohhot implemented "coal-into-electricity", "coal-into-gas", and "coal-into-central heating" projects for 148,400 households. In a 617-square-kilometer high-pollution no-burn zone, coal burning has been eliminated, with an 86 percent clean heating rate realized in rural areas. Hohhot also constructed and upgraded 586 km of 10-kilovolt power lines, installed 2,095 transformers, and built 236 km of new gas pipelines.
