1. Small-scale electrical grids that can operate independently or in connection with the main power grid, typically serving a localized area such as a building, campus, or community.
Usage: plural form of microgrid; technical term used in energy and electrical engineering; increasingly common in discussions of renewable energy and grid resilience

Examples

• Many universities are installing microgrids to reduce their dependence on the main power grid.
• Microgrids can integrate solar panels, wind turbines, and battery storage systems.
• During a blackout, microgrids can disconnect and continue supplying power to critical facilities.
• The city is developing microgrids in several neighborhoods to improve energy resilience.
• Microgrids are becoming more affordable as renewable energy technology advances.
• Hospital microgrids ensure that essential services remain operational during grid failures.
