What is a Microgrid?

Traditional electricity grids were built to be large remote power plants and were generally located long distances from customers. According to General Electric EcoImagination Group’s “The Rise of Distributed Power” the transition to distributed energy started two decades ago in the late 1990’s and early 2000’s. Efficiencies were expected from shifting away from centralized systems toward integrated local networks and more distributed energy resources located near customer locations. The transition is also the result of challenges related to political, technical, environmental and funding constraints of building large power plants and distribution systems. Microgrids are small, easier to finance, quicker to build and operate and can be added as new energy needs arise.

Microgrids are also great for countries like Brazil, India and China which have huge populations with lower per capita income levels and where smaller distributed projects often make more sense than huge plants.

Microgrids Provide More Resiliency to Local Areas

Today cities, communities and campuses across the United States and around the world are searching for greater energy efficiency, reliability and resiliency as they grapple with environmental and economic challenges.

These groups are building microgrids that leverage local energy, heat and power systems. Smart microgrids make it easier to control, produce and distribute electricity and thermal energy to local customers while simultaneously operating in parallel with large regional electric grid operators.

Advantages of Microgrids

Using advanced technologies such as responsive balancing of capacity microgrids more efficiently handle succeed in lowering peak electricity demand and relieving strain on large grids. Over time, microgrids also reduce and eventually eliminate intermittent renewable resources as batteries are now able to store energy over longer and longer time periods.  Finally, microgrids run in parallel with larger grids can connect or supplement large grids through efficiently managing energy consumption.

Following is a YouTube video explaining the transition from large grids to microgrids:
