What are microgrids – and how can they help with power cuts?
Summary
Microgrids are local power grids that can operate independently from the main electricity grid, providing resilience during outages through 'islanding' and delivering power to remote areas. They increasingly rely on renewable energy sources such as solar, wind, and hydropower to reduce greenhouse gas emissions. According to the International Energy Agency, decentralized solutions are the most affordable way to provide electricity to the approximately 770 million people without access, primarily in Africa and Asia.
Key insights
- Microgrids are local power grids capable of operating independently of the main electricity grid to power individual buildings, collections of buildings, or larger areas like towns and cities. They provide critical resilience during main grid failures through a process called 'islanding'.
- The International Energy Agency (IEA) identifies decentralized solutions, including mini-grids and stand-alone systems—which are 90% based on renewables—as the most cost-effective method to provide power for half of the 770 million people globally who lack electricity, mostly in Asia and Africa.
- There are three primary types of microgrids: remote (off-grid) systems for areas too distant for main grid connection, grid-connected systems that can switch to independent mode during supply issues, and networked microgrids that link multiple units to serve wider geographic areas.
- Global distribution of microgrid capacity is led by Asia Pacific, followed by North America, the Middle East, and Africa. Specific examples include 160 microgrids in the US (concentrated in Alaska, Texas, New York, and California) and 160 in India, where over 80% are solar-powered.
