State Grid Zhenjiang's zero-carbon power service helps firms save energy, increase efficiency

At Wetown Electric Group in Yangzhong, a county-level city in Zhenjiang, Jiangsu province, customer manager Zhu Yujin from State Grid Zhenjiang Power Supply Company conducted an on-site energy follow-up and used digital tools to diagnose energy use on Sept 20.

After retrofitting, the company's energy efficiency rose 15 percent, and it passed several certifications and secured preferential loan rates. The results came from the zero-carbon power service launched by State Grid Zhenjiang this year.

As the dual-carbon strategy picks up steam, companies' environmental performance is increasingly affecting loans and exports. During earlier visits, many firms said their energy-saving projects lacked unified guidance, follow-up, and verified data on energy savings and carbon reductions, leaving them without supporting materials for certification.

To address this, State Grid Zhenjiang began implementing the Electric Warm Current 2026 practical initiatives in July. Focusing on expanding energy- and carbon-efficiency services, it launched the zero-carbon power service. Using digital applications, the service bundles green electricity trading, carbon management consulting, and energy-saving renovations.

Using electricity data, the company identifies areas where businesses fall short of relevant energy and carbon standards and recommends improvements. The service brings previously separate services — from energy-efficiency assessments to carbon footprint certification — into a single process, with State Grid Zhenjiang providing support throughout.

Wetowm Electric, one of the first pilot firms, completed carbon footprint certification for two core products through the service.

The service team first performed a comprehensive energy-carbon health check. It retrieved historical electricity and energy data online and verified production lines on-site, calculating energy use and carbon emissions for each process and piece of equipment. It then compared the findings with Jiangsu's zero-carbon factory standards, helping the company meet application standards.

Guo Cheng, Wetown Smart Energy's deputy general manager, said that in the past, energy-saving renovation, carbon accounting, and green electricity procurement required coordinating with multiple institutions, often with inconsistent data standards.

Now the power company guides and tracks the whole process. After renovation, two core products obtained carbon footprint certification, which helped secure preferential bank loan rates.

So far, State Grid Zhenjiang has conducted more than 100 energy-efficiency inspections, reached pilot cooperation agreements with five companies, and saved nearly 5 million yuan ($746,148.76) in electricity costs.

Wetown Electric has received a zero-carbon factory certificate from SGS, an internationally recognized certification body, and reduced annual energy costs by more than 15 percent.
