Yunnan Province has issued its first local standard regulating grid-connected operations for major power consumers. On June 9, the Technical Specifications for Grid Operation of Electrolytic Aluminum Users in Yunnan (DB53/T 1414-2025), developed by Yunnan Power Grid Co. under China Southern Power Grid, was officially released.
In recent years, industrial electricity demand in Yunnan has surged, with large consumers—particularly electrolytic aluminum producers—becoming key to the province’s renewable energy consumption. These users now account for about 30% of Yunnan’s total electricity usage, making them the most influential industrial power consumers in the region.
As renewable energy capacity continues to expand, China’s power system is shifting from the traditional “generation-follows-load” model to a more dynamic system of intelligent coordination among generation, grids, loads, and storage. In this context, large industrial users are evolving from passive recipients of electricity to active participants in grid operation and system balancing—playing an increasingly important role in ensuring power system reliability and flexibility.
Tailored to Yunnan’s local conditions, the new standard sets out comprehensive technical requirements for the grid participation of electrolytic aluminum users. It fills a gap in local standards for coordination between high-consumption users and the grid, and represents a key step toward a more standardized and integrated approach to grid-load coordination in the province’s emerging power system. The standard is expected to help improve grid stability while enhancing the province’s ability to absorb renewable energy.
