There is a big difference between the feasibility estimate based on the analysis of historical price information and the actual project cost, which leads to a high project balance and reduces the investment benefit of the company. Taking the substation project as an example, this paper analyzes the change law of the main equipment price in recent years, studies the impact of the price change of the main equipment on the cost, assists the project cost prediction, supports the analysis and evaluation of the feasibility study estimation, reduces the balance rate, optimizes the investment strategy, reduces the project investment risk, and improves the lean management level of the project investment.
