Key Technologies for Carbon Reduction throughout the Entire Process of Green Power Construction

In the context of the national "dual carbon" goals — namely, achieving carbon peaking and carbon neutrality — transmission and transformation projects, as an essential component of the power system, play a pivotal role in promoting green construction practices and advancing carbon reduction efforts. These projects not only serve as critical infrastructure for the reliable delivery and transformation of electrical energy but also represent key opportunities for integrating sustainable technologies and achieving substantial reductions in carbon emissions throughout the engineering lifecycle. Against this backdrop, this paper focuses on the development and application of key technologies that support carbon reduction across the entire green construction process of transmission and transformation projects. Specifically, it introduces the FCCSP (Full-process Carbon Control and Smart Planning) management system, which provides an integrated framework for systematically controlling carbon emissions at every stage — from project design and material selection to construction, commissioning, and long-term operation. Furthermore, the paper details a series of core technological innovations that enhance the carbon reduction capability of these projects, including advanced materials, intelligent construction techniques, and data-driven carbon management tools. The effectiveness and practical value of these technologies are rigorously validated through a set of representative engineering case studies, offering both theoretical insights and empirical evidence. In doing so, this research provides a comprehensive reference for advancing the low-carbon transformation of transmission and transformation projects, and contributes valuable guidance for achieving the broader objectives of sustainable power system development.
