What information is collected and what research is conducted in the field of feasibility studies for power infrastructure development?

　　(1) Power plant construction shall, based on thermal load and installation schedule, as well as forecasts and analyses of thermal load trends and power load projections, formulate a comprehensive load table and typical load curves in accordance with the design. An analysis shall be conducted on the nature, scale, installed capacity, unit types, installation schedule, and phased construction of this power plant, and corresponding power supply recommendations for the plant shall be put forward. Furthermore, connection schemes between the power plant and the grid shall be studied, the outgoing line voltage level and the number of outgoing circuits shall be justified, and the transmission projects and associated scope to be constructed concurrently with the power plant shall be substantiated.

　　(2) Fuel supply for power construction. Collect data on coal mine reserves, mining output, and the quantities to be supplied in accordance with the construction schedule, as well as coal quality parameters (moisture content, ash content, sulfur content, calorific value, etc.), pricing, and transportation methods.

　　(3) Water sources for factory sites in power construction projects. This section elaborates on the required supplementary water quantities under conditions of various site-specific water supply sources, circulation schemes, cooling water requirements, and water conservation measures; presents hydrological reports or preliminary hydrogeological reports for different water supply sources; and, with the approval of the local water resources management authorities and based on relatively reliable baseline data, proposes preliminary water supply schemes for various cooling methods along with a technical and economic comparison.

　　(4) Ash-removal system and ash-repository site. Provide preliminary design schemes for the ash-removal systems at each plant site, including conveyor lengths, conveyor heights, and integrated utilization design requirements. Specify the area required for ash disposal, the area to be demolished for building relocation, as well as data on lake characteristics, flash-flood discharge, flood levels, tidal levels, dewatering measures, engineering geological and hydrogeological conditions, dam materials, transportation distances, and transportation conditions.

　　(5) Engineering Geology. A separate engineering geology investigation report shall be submitted, which shall identify structural faults relevant to the stability of the plant site, determine the basic seismic intensity for the site, analyze the seismic design requirements for the site, characterize the soil types at the construction site and assess the potential for and countermeasures against liquefaction of the foundation soils, and evaluate the overall stability of the plant site.

　　(6) Engineering Philosophy. This primarily involves studying the main process systems and key technical principles and schemes for new, expanded, or reconstructed power plants, which serve as the basis for project investment estimation and economic benefit analysis.

　　(7) Environmental Protection. In accordance with the State’s “Environmental Protection Law” and “Environmental Impact Assessment Law,” as well as the former Ministry of Electric Power’s “Emission Standards for Air Pollutants from Coal-Fired Power Plants” and “Provisional Regulations on the Depth of Content in Environmental Impact Reports During the Feasibility Study Phase of Thermal Power Plants,” an Environmental Impact Report was prepared and submitted to the provincial and municipal environmental protection authorities for approval.

　　(8) Economic Benefit Analysis. Based on the major process systems and key technical principles and schemes considered in the recommended plant design and engineering concept, conduct an investment estimation for the project. Calculate the power generation cost and compute economic benefit indicators in accordance with the “Detailed Implementation Rules for the Economic Evaluation Method of Power Construction Projects” issued by the China Electric Power Planning & Engineering Institute.

　　(9) Summary and Technical-Economic Indicators. This section synthesizes the issues examined in the preceding chapters of the feasibility study, presenting the main conclusions and overall evaluation. It also identifies key issues and offers recommendations, along with a detailed explanation of various technical and economic indicators. Concurrent with the feasibility study, the power company shall submit the “Design Assignment Document” and, with the assistance of the design institute, provide the requisite data. The site-selection report for the transmission line shall be developed in tandem with the rest of the study. For the time being, the specific transmission route has not been finalized; however, if the line length is substantial, a preliminary survey may be conducted.
