Construction course of Shuanghuai thermal power plant

On February 19, 2003, China Electric Power Group officially signed a contract with Chongqing Planning Commission, with the first phase investment of 51900,000 yuan to build Hechuan Shuanghuai Thermal Power Plant and become the owner of the thermal power plant.

In April 2004, the first phase of Shuanghuai Thermal Power Plant was officially started. In the first phase, 600,000 kilowatts of domestic subcritical coal-fired generating units will be built, and flue gas desulfurization devices will be built simultaneously. On August 2, 2006, at 6: 30 pm, the first phase project of Shuanghuai Power Plant with an installed capacity of 300,000 kWh 1 unit was successfully completed 168 hours of full-load trial operation, and the input rate of main protection devices 100%. This indicates that the power plant 1 unit has completed the transformation from the capital construction stage to the production stage and officially entered the commercial operation.

June 5438+October 2006 10, Unit 2 of the first phase project of Shuanghuai Power Plant with the same installed capacity of 300,000 kWh was officially put into operation.

On August 7, 2009, the National Energy Administration approved the preliminary work of the second phase of Shuanghuai Thermal Power Plant in Hechuan, which means that the second phase of Shuanghuai Thermal Power Plant has entered the substantive implementation stage. The total investment of the second phase project of Shuanghuai Thermal Power Plant is nearly 5 billion yuan. After the completion of the project, the new power generation will be 6.5438+0.32 million kWh, which will provide a lot of electricity for Chongqing.

201116543817 October, the National Development and Reform Commission issued the Reply on Agreeing to the Phase II Expansion Project of Shuanghuai Power Plant in Hechuan, Chongqing, officially approving the construction of the Phase II Expansion Project of Shuanghuai Power Plant in Hechuan District, which marked a breakthrough in the project. It is reported that the project will start construction in early February of 20 1 1. Yu, head of the Economic Reform Section of Hechuan District Development and Reform Commission, said that the second phase expansion project of Shuanghuai Power Plant plans to build a 2× 660 MW domestic ultra-supercritical coal-fired generator set and simultaneously build a coal-carrying railway line. The National Development and Reform Commission approved the construction of the first batch of1660,000 kW generating units, with an estimated total investment of 2.78 billion yuan, which is expected to be put into operation in 20 12 years. After the power plant is put into operation, the annual coal consumption is about 6.5438+0.4 million tons, and the annual water consumption is about 7.65438+0.5 million cubic meters. The water comes from Qujiang. The project will install high-tech devices such as high-efficiency electrostatic dust removal, desulfurization, denitrification and on-line continuous monitoring of flue gas, and all emission indicators meet the national environmental protection requirements. The second phase expansion project of Shuanghuai Power Plant is not only a national key project, but also a key measure for Chongqing to build the largest energy base in the north.
