What is a Microgrid?

A microgrid is a small-scale electrical grid that can work autonomously from the centralized electricity grid. A microgrid is a type of local energy grid. When the centralized energy grid fails, a microgrid provides the energy needed.

Microgrids Aid Centralized Energy Grids

A microgrid works with the centralized energy grid, otherwise known as the macrogrid. The macrogrid connects buildings to central power sources, providing the use of electronics and heating/cooling systems. This interconnectedness means that when part of the macrogrid fails, the entire macrogrid fails, causing a power outage.

Microgrids Generate Energy Needed

When the macrogrid fails, a microgrid can power a designated area with its own local energy production. A microgrid can generate energy for however long is needed from a variety of sources, including natural gas lines, wind turbines, or solar panels. It can be managed automatically or manually.

Other Benefits of Microgrids

A microgrid functions as a backup energy source during power outages. It can also decrease energy costs and dependence as well as increase environmental friendliness. A microgrid can also be used to power a variety of smaller resources that are otherwise not fit for traditional grid use. One microgrid can be used to power a single facility or an entire district.
