With the current climate change situation, such prolonged extreme weather has caused the demand for electrical equipment to increase very high, the capacity requirement of the power system has increased to a record high and wind power sources have increased. Solar power has unstable characteristics with many erratic changes. Therefore, the requirement to ensure safe and reliable operation of the plant must be given top priority, requiring solidarity and consensus from the Company's Board of Directors to all employees in the factory.
To complete the assigned economic and technical targets as well as ensure the safe and stable operation of power units, furnaces, and load systems, the Company has proposed a series of basic solutions.
Specifically, the Company has systematically carried out testing, periodically changed equipment, and continuously reviewed and checked equipment status to detect and promptly handle equipment defects and abnormalities. Every month, the operation teams script and rehearse incidents according to the established plan, and at the same time disseminate to all operating staff typical incidents of the plants to improve experience and prevent incidents.
Moreover, the Company always prepares adequate fuel including coal, HFO oil, DO to be ready to meet mobilization needs; reviews and prepares adequate supplies, especially for equipment that frequently changes working modes, ensuring operational reliability.
As a result, in the first 7 months of 2023, the Company has produced an electricity output of 2,411.97 million kWh, reaching 95.83% (2,516.97 million kWh) of the Ministry of Industry and Trade's 7-month plan and reaching 62.68 million kWh. % (3,847.92 million kWh) of the yearly plan of the Ministry of Industry and Trade; reaching 101.22% (2,383 million kWh) of EVNGENCO1's 7-month plan and reaching 64.93% (3,715 million kWh) of EVNGENCO1's yearly plan.

Not only emissions parameters (dust concentration, exhaust flow, SO2, NOx... and parameters of industrial wastewater and cooling water such as pH, chlorine content, TSS, wastewater temperature...) are displayed on the Electronic Board, but also the standard values according to National Technical Regulations on industrial waste are displayed for people and local authorities to monitor, compare and evaluate.
With the motto of operating the plant safely and ensuring the environment, leaders and employees of Nghi Son Thermal Power Company have set management and operation goals to ensure the maintenance of emission targets below the allowed value. For exhaust gas is NOx 850mg/Nm3, SOx 425mg/Nm3, Dust 170mg/Nm3 and for allowed wastewater is residual chlorine 1.17mg/l, temperature 400C, TSS 58.5mg/l, contributing to the supply Providing electricity for national economic development and environmental protection for the entire society.
