“Three-renovation”(energy-saving renovation

flexibility renovations and heating renovations) of coalfired power is an effective measure for clean and low carbon utilization of coal. The paper analyzes current energy efficiency

flexibility and heating situation of coal-fired power

and researches the policy requirement

implementation progress and expected effect of “Three-renovation”. In terms of technical difficulty

energy saving renovation is the most difficult

followed by flexibility and heat supply. It is anticipated that the coal consumption for power supply will be decreased to about 297 g/(kW·h)

the additional peak regulation capacity will be over 40GW and the heating scope will be further expanded. In view of the problems such as large coal power loss

difficult technical transformation of some types

hidden safety risks of equipment under low load operation

unanticipated input and output of renovation

and small financial support of renovation

this paper puts forward measures and suggestions to promote the “Three-renovation” from the perspectives of policy

technology

standards and market.
