Microgrids, Explained

The landscape of energy generation and distribution is in a constant state of change and evolution. Governments at various levels, be it local, state, and national, are constantly striving to build power grids that are not only stable but also sustainable. One such change that has gained traction is the introduction of microgrids.


These localized power grids offer smaller areas a reliable source of power, even in times when the main grid is unstable or facing interruptions. In this guide, we will delve deeper into the world of microgrids, exploring how they differ from traditional grids, their primary purpose, and their potential to pave the way for a greener and cleaner energy future.



What is a microgrid?

A microgrid is a small-scale version of an interconnected electricity system that can generate, distribute, and regulate the flow of electricity within a specific geographic location. It consists of distributed energy resources (DERs) such as solar panels, wind turbines, batteries, and backup generators that work together to provide power to a local area.


Why is the purpose of a microgrid?

Microgrids serve as a vital source of reliable and efficient power for specific areas or facilities, such as college campuses, hospital complexes, business centers, and neighborhoods. Not only do microgrids fulfill this primary function, but they also play a secondary role in reducing carbon emissions. By harnessing renewable energy sources, these modern microgrids actively contribute to curbing greenhouse gas emissions, promoting energy independence, and fostering sustainability. Furthermore, these compact utility grids hold the potential for substantial energy cost savings, bolstered grid resilience, and heightened energy efficiency.


What are the different types of microgrids?

Different types of microgrids cater to different energy needs, and they can be broadly classified into three categories: connected, remote, and networked.


  • Connected Microgrids are linked to the main power grid but have the ability to operate independently if needed. This model uses the microgrid as a backup power source if the larger grid loses power. This type of microgrid is commonly found in urban or suburban areas, and is ideal for colleges and hospitals.

  • Remote Microgrids, on the other hand, are located in isolated regions that lack connection to the main grid. These off-grid microgrids rely on local energy sources and storage to provide power to their communities. Remote microgrids are typically completely self-sufficient and do not require any connection to the main power grid.

  • Networked Microgrids are a combination of both connected and remote microgrids, where multiple smaller grids are interconnected to form a larger, more resilient grid.


Why are the benefits of microgrids?

Microgrids are designed to operate independently or in conjunction with the main power grid, depending on the specific needs of the community they serve. During power outages or emergencies, microgrids can disconnect from the main grid and function as an autonomous power source. They can seamlessly reconnect with the main power grid as required. This flexibility not only enhances the overall resilience of the grid but also mitigates the risk of widespread blackouts.


What is the future of microgrids?

Microgrids hold great promise for shaping the energy landscape. Microgrids are becoming increasingly popular due to their ability to provide reliable and resilient energy supply to communities.  As the demand for clean and sustainable energy continues to rise, microgrids will play a critical role in meeting these demands.


Additionally, microgrids are an effective way to generate electricity onsite rather than relying on the main power grid. These localized and decentralized power sources offer greater flexibility, autonomy, and cleaner energy.  Moreover, they offer an opportunity for communities to become self-sufficient in their energy needs. They can generate and store their own power, reducing dependency on external sources and providing greater control over energy costs.


Microgrids also have environmental benefits as they use renewable energy sources, reducing the reliance on traditional fossil fuels, leading to a reduction in greenhouse gas emissions while contributing to the fight against climate change. Property owners interested in contributing to the generation of renewable energy can lease their land to energy developers for clean energy projects, such as solar or wind farms.
