The National Energy Administration (NEA) officially launched the pilot of thermal power flexibility transformation on June 14, according to the Memorandum of Understanding on the Establishment of Sino-Danish Thermal Power Flexibility Partnership and work arrangement for cooperation platform for thermal power flexibility enhancement.
The pilot reflects the following principles: 1) meeting the requirements of the transformation of central and local power companies; 2) focusing on renewable energy absorption and power-heat contradiction; 3) giving priority to areas surrounding large cities and heat load sufficient areas, to achieve thermoelectric decoupling effect; 4) taking into account condensing unit transformation of the power system adjustment capacity building program during the 13th Five-Year Plan period.
Based on preliminary research on technical roadmap and comprehensive comparison and selection, a total of 15 pilot projects are identified, concentrated in areas with prominent renewable energy absorption problem, including Liaoning, Jilin, Heilongjiang, Inner Mongolia, Hebei, Guangxi and involving Huaneng, Datang, Huadian, Guodian, Shenhua, SDIC, and TieFa Coal Industry Group.
The pilot is expected to increase the peaking capacity of cogeneration units by 20% of the rated capacity and minimum technical output by 40% -50% of the rated capacity. For condensing units, the number will read 15% -20% and 30% -35% respectively. By strengthening domestic and international technical exchanges and cooperation, a group of transformed power plants will reach the international advanced level, and the minimum technical output of condensing units under stable load without auxiliary fuel support will attain 20% -25%.
NEA strives to complete the pilot within the year by guiding the cooperation platform to provide technical support with reference to advanced international experience, organizing and coordinating the implementation of technical programs in the pilot projects, and introducing supporting policies and incentives. The lessons learnt will summed up and spread, so that the thermal power flexibility transformation can play the due role in improving peaking capacity and new energy absorption and further promoting efficient, intelligent power system.
