The Wuhai pumped storage power station

as a crucial energy infrastructure project in western Inner Mongolia

faces challenges in investment management due to its large scale

long duration

and complex multi-party collaboration. In response to these challenges

this paper designs and implements an investment management system based on modern information technology and advanced management concepts. The system adopts a microservices architecture

encompassing a client layer

application layer

microservices layer

and infrastructure layer

and includes six core functional modules: contract management

budgetary estimate management

bidding management

planning management

electromechanical equipment management

and material management. Through a mobile app and a centralized "investment map" visualization hub

the system breaks down data silos from multiple sources

enhances collaboration among various roles

and improves investment transparency and decision-making efficiency. The system effectively addresses issues such as contract change risks

budget overrun warnings

and inefficient fund allocation

providing a digital and standardized management paradigm for the construction of the pumped storage power station. This significantly reduces management costs and mitigates financial risks.
