Microgrids are electrical power networks designed at smaller scales than typical ‘national grids’. Often built around the buildings, communities, or wider infrastructure they serve, they can generally operate both alongside, or independent from a larger grid. Microgrids tend to have their own energy generation sources, such as solar panels or wind turbines, which are connected to local energy users, and increasingly, energy storage systems batteries as well. In these cases, a local microgrid can largely power a community on clean energy alone.

Given their distributed generation and ability to operate independently, microgrids are often resilient to disruptions from weather or other disasters that affect larger power grids. Their smaller scale makes it easier to add additional renewable generation, and being closer to users reduces power lost in transmission over long distances. Today, in many isolated or rural communities, especially in Global Majority countries,  microgrids are often easier to build than fossil-energy infrastructure, providing the opportunity to build a clean energy system from the ground up, rather than adapting an existing, dirtier system. 

Microgrids do face financial and legal barriers. Raising funds can be difficult, especially given the smaller scales and variety of designs. At the same time, most places lack a clear legal definition of a microgrid and this makes complying with local laws difficult, while increasing permitting costs.

National or local governments and utility companies are often the most important decision makers when it comes to supporting the growth of microgrids. Partnerships between public and private institutions can sometimes help overcome challenges, so a system might be built and operated by the combination of businesses, utilities, communities, and government. Whatever shape microgrids might take, consistent, supportive policies and comprehensive standards are key.
