Low carbon design schemes had been adopted for Guodian Jianbi Power Plant project (2×1 000 MW units). This paper proposed the calculation formula of low carbon design for condensing units, and analyzed the low carbon design for the project from four aspects: system design and main equipment selection, optimization design, energy saving design and design requirements of energy-saving management during operation. In addition, the major features of low carbon design were also introduced comprehensively. The low carbon design for Guodian Jianbi Power Plant has remarkable achievements, whose experience can be a reference for similar power plants.
