To promote the orderly development of the energy and power industry and meet the planning and needs of the smart cities in the Greater Bay Area (GBA), Companhia de Electricidade de Macau - CEM, S.A. (CEM) actively participated in the compilation of the group standard “Technical Specifications for Smart Distribution Substation” (T/GDEA 001-2024). After many efforts, the Specifications were officially released and implemented on 19 February 2024, marking another advancement in the standardization of China's power industry.

The compilation of the Specifications was led by Guangdong Energy Association, with the participation of 19 units including Guangzhou Southern Investment Group Co., Ltd., CEM and other relevant enterprises in the GBA. The Specifications clarify the configuration principles, technical conditions, and testing requirements for smart distribution, including the technical requirements and on-site inspections for power equipment monitoring, environmental monitoring, security monitoring, intelligent gateways, and communications in distribution substations. It provides detailed technical guidance and specifications for the construction and management of smart distribution substations. The implementation of the Specifications will effectively promote the standardization and normalization development of the national smart distribution substation technology, meet the needs of technological and market innovation in the energy field and smart distribution substations, and contribute to the construction of smart cities.

Smart distribution substations are crucial in the modernization of energy infrastructure, providing safe, reliable, and efficient electrical support to new urban developments. As early as 2022, CEM has cooperated with the University of Macau to carry out a pilot project of smart distribution substations, installing intelligent sensors in 5 distribution substations. The pilot project used an online monitoring system to monitor the operational status of power equipment in real-time to ensure the stable operation of the power supply system. Valuable experimental data and practical experience were collected for the compilation of standard.

CEM has always been concerned about the sustainable development of the industry, actively participating in the formulation and improvement of industry standards with its professionalism. For many years, it has continuously conducted power industry-related training courses, optimized the registration system for local power industry talents, and cultivated more professionals for the industry. CEM also actively engages in exchanges and explorations with various academic institutions and suppliers, covering all-round development areas of the power industry, including carbon neutrality, smart grids, clean energy, EV charging, big data, artificial intelligence, communication technology, and cybersecurity, etc., resulting in a series of collaborations and achieving concrete results.
