At 1:12 a.m. on November 21, the waste heat generator set at Yan’an Energy Chemicals successfully generated electricity and was connected to the grid on the first attempt. This power generation unit primarily uses the waste heat steam generated by chemical processing units to produce electricity; it serves as a key factor in helping the company reduce costs and increase efficiency, while also enhancing the stability and reliability of the power supply provided by the company. In the generator set plant, the Electrical and Instrumentation Center as well as the Thermal Power Center of Yan’an Energy Chemical Company carried out the necessary pre-startup inspections. At 1:08 a.m., they submitted an application to the Shaanxi Electric Power Company’s Control Center (referred to as the Provincial Control Center) to connect to the power grid. One minute later, following instructions from the Provincial Control Center and after further inspections, the company activated the automatic synchronization procedure, and the waste heat generator set was successfully integrated into the Shaanxi power grid. It is understood that the company has two waste heat generator sets, both with a rated capacity of 50MW. In April of this year, the approval document from **Grid Shaanxi Electric Power Company for power generation and grid connection was obtained. After completing the design, construction, unit commissioning, and other preparatory work related to grid connection, a commissioning committee for the waste heat generator set was established, consisting of **Grid Shaanxi Electric Power Company, **Grid Yan’an Power Supply Company, Yan’an Energy & Chemical Company, and all other parties involved in the project. With the authorization of this committee, the operation command team for the waste heat generator set officially initiated the process of power generation and grid connection on November 20th. Once the two generator sets are put into operation, they are expected to generate 520 million kWh of electricity per year, saving the company 260 million yuan in electricity costs.
