Microgrid investment analysis involves a comprehensive evaluation of the financial viability, technical feasibility, and sustainability impact of proposed microgrid projects. This evaluation assesses the capital expenditure required for generation assets, storage, and control systems, alongside. This paper presents the Microgrid Performance and Investment Rating (MPIR) index, a novel assessment framework developed to link economic and environmental objectives within microgrid configurations. The MPIR index evaluates microgrid configurations based on five critical dimensions: financial. EPRI's cost-benefit analysis framework for microgrids offers an objective, consistent, and repeatable approach for assessing the value proposition of differing microgrid designs, use cases, distributed energy resources (DER) technology mixes, ownership configurations, and other contexts. This rigorous process determines whether the quantifiable benefits, encompassing economic savings, resilience value, and. Amid high renewable penetration, market reform, and dual-carbon goals, microgrids are expected to deliver economic, environmental, and technical value, yet much work remains static or single-dimensional and lacks a closed loop from evaluation to fair sharing and incentives. This paper proposes an. • Microgrids offer economic advantages and enhance reliability. •Significant timeandengineering effortis needed to integrate the control and communication systems. •Interoperabilityof the various systems involved isa critical challenge.
