At the same time, it hopes to lead domestic thermal power plants to advance toward the road of Sustainable Development of energy efficiency and environmental protection by aiming at cleaner production and zero pollution. This research identifies three kinds of different scenarios (scenario 0, scenario 1 and scenario 2) and carries out the performance assessment respectively. The obtained result is as follows: First, scenario 0 mainly calculates the weighed scores of pollution prevention index, and its average score is highest in the assessment. Because the present domestic Thermal Electricity Plant are well equipped in the prevention and control of pollution, exhaust gas emission has mostly conformed to the BACT emission standard, and wastewater emission is far lower than the standard. Second, scenario 1 mainly calculates the weighed scores of power generation efficiency and the reuse of resources. Compared with the scenario 0 scores, it puts more emphasize in power generation efficiency, energy conservation measures, waste-heat recovery efficiency, and resources reuse efficiency. It can also underline energy conservation and carbon reduction quite well, which conforms to the government’s policy in reducing greenhouse gas emission. Third, scenario primarily emphasizes environmental management. Its scores are lowest after weighing environmental management index scores. This is mainly because most power plants have not obtained the ISO 14064-2 certification and the environmental education hour has not reached 24 hours. Although obtaining the ISO 14064-2 certification will increase the scores, it is likely to neglect energy consumption, resource reuse, etc, while implementing the assessment.
