A mission-critical microgrid comprising a renewable energy generator, a microgrid control and distribution unit, electric vehicle supply equipment, an energy storage system, and critical infrastructure electric service equipment. The renewable energy generator generates and provides direct current (DC) power that is then controlled and distributed by the microgrid control and distribution unit. The electric vehicle supply equipment receives DC power from the energy storage system through the microgrid control and distribution unit to be utilized to charge a mission-critical electric vehicle fleet. The mission-critical electric vehicle fleet supplies DC power through the electric vehicle supply equipment to the energy storage system through the microgrid control and distribution unit. The energy storage system receives, and stores DC power generated by the renewable energy generator through the microgrid control and distribution unit. The critical infrastructure electric service equipment receives alternating current (AC) power through the microgrid control and distribution unit that is inverted from the DC power created by the renewable energy generator and stored by the energy storage system, wherein the AC power is used to power a critical infrastructure.
