Executive Summary A major operator of public fast EV charging stations aims to establish a state-of-the-art charging facility featuring 23 EV chargers, supported by distributed energy resources (DERs) and battery storage. The objective is to minimize reliance on the grid, reduce operating costs, and provide a seamless fast charging experience for EV owners. DG Matrix has developed a customized energy management solution centered around its innovative Power Routers to achieve an IRR of more than 30% with a payback period of 4 years. Challenges The operator faces significant challenges in designing and deploying this flagship public fast EV charging facility: High Energy Demand: Rapidly fast charging 23 vehicles simultaneously creates substantial peak loads, leading to elevated demand charges and increased stress on the local grid infrastructure. Grid Dependency: Relying on the grid for peak energy requirements increases exposure to potential disruptions and higher electricity prices.

Scalability Constraints: Expanding the number of fast chargers and integrating additional renewable energy sources require costly infrastructure upgrades. Sustainability Commitments: The operator must align with environmental, social, and governance (ESG) goals by incorporating renewable energy solutions. Deployment Timelines: Rapid commissioning is critical to meeting market demand and operational deadlines. Requirements and Priorities The EV charging operator outlines the following priorities to address these challenges: Cost Optimization: Minimizes both capital expenditures (CapEx) and operational 1 expenditures (OpEx) while maintaining profitability. Resiliency: Ensures uninterrupted fast charging services for EV owners, even during grid outages. Sustainability: Maximizes renewable energy usage and reduces carbon emissions. Scalability: Future-proofs the facility for easy integration of additional fast chargers and energy sources. Operational Simplicity: Implements a centralized energy management platform for seamless operation and monitoring.
