State Grid Anhui Electric Power Marketing Service Center builds Yangtze River Delta's first full-link power grid carbon emission monitoring platform

The Marketing Service Center of State Grid Anhui Electric Power completed the construction of the province-wide full-link power grid carbon emission monitoring platform on Dec 1, which stands as the first of its kind in Anhui province and even across the entire Yangtze River Delta. At present, the platform has pioneered the establishment of an electricity-carbon metering network covering power plants, substations, and end-users across the province. It has successfully achieved three-level (provincial, municipal and county) integrated electricity-carbon monitoring as well as accurate carbon emission monitoring across all power grid segments. This initiative fills the gap in comprehensive and refined carbon emission monitoring within Anhui's power system, providing robust data support for the regional implementation of the "dual carbon" goals.

Based on the actual conditions of Anhui's power grid, the center has adopted an innovative and scientific implementation approach based on a "pilot verification followed by province-wide promotion" model. In the early stage, during pilot construction in Anqing and Bengbu, the center successfully tackled the technical challenges of step-by-step carbon emission monitoring spanning from power plants to the grid side to end-users. It also established a complete theoretical system and practical paradigm for electricity-carbon metering technology. Building on the pilot achievements, the platform has expanded its monitoring coverage to the entire province through the integration of multi-source data resources, achieving full coverage of electricity-carbon monitoring for the province's main power grid. Leveraging data homology governance and intelligent algorithm modeling technologies, the platform breaks through the fragmented barriers of traditional power carbon emission monitoring, and constructs a three-dimensional monitoring network that is "vertically integrated across the provincial-municipal-county levels and horizontally covers all links including power generation, transmission, distribution, transformation and consumption". Taking advantage of the massive data collection capability of over 40 million operational electricity meters and more than 500,000 operational terminals across the province, the platform realizes real-time capture and accurate accounting of carbon emission data from substations of different voltage levels. In terms of visual presentation, the "Anhui Electricity-Carbon Map" innovatively uses geographic information as the carrier to intuitively display the distribution and flow direction of carbon emissions across various regions and voltage levels, providing decision-makers with an efficient research and judgment tool for "full-province overview on one screen".

The platform will be able to provide precise data references for the formulation of regional carbon peaking and carbon neutrality policies and strongly support the implementation of the dual control system for total carbon emissions and emissions intensity. It will also support the optimization of clean energy consumption and power grid dispatching decisions, promoting the development of a new type of electricity-carbon coordinated dispatching system. In the future, it will provide personalized carbon emission monitoring services for dedicated-line users, helping high-energy-consuming enterprises achieve low-carbon transformation.

Moving forward, the Marketing Service Center of State Grid Anhui Electric Power will follow a plan to "expand from dedicated-line users to all users" and continuously advance the development of the platform. It will gradually extend the monitoring scope to all distribution and consumption links, and ultimately build a province-wide full-chain electricity-carbon monitoring network. Meanwhile, the center will further optimize the electricity-carbon metering model to improve the spatiotemporal resolution of data, and actively explore the connection and application of the platform with green finance, carbon trading markets, and other fields, so as to fully unleash the value potential of power big data in driving low-carbon transformation.
