The United States Department of Energy Microgrid Exchange Group defines a microgrid as ''''a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid. A microgrid can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode.''''
Going ''off-grid''
In the thrall of the increased electricity independence that solar PV systems can provide, it''s been accompanied by the idea that getting ''off-grid'' – a suburban household completely cut off from the rest of the grid – is some kind of energy nirvana: the ultimate act of defiance by individuals against big energy companies and governments.

Replacing fossil fuel-based power generation with power generation from wind and solar resources is a key strategy for decarbonizing electricity.
How Energy Storage Works | Union of Concerned Scientists
Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the ...

The Road to Resilience with Rooftop Solar | Department of Energy
Microgrids are localized energy grids that can disconnect from the main grid in a crisis and continue to operate on its own. Last year we showed that a microgrid in Chicago provided power entirely on its own to residences and businesses, drawing on power from battery storage and community solar systems.
What can energy storage do besides provide backup power for the grid?
In leading states like Texas and California, battery energy storage installations are driven by a desire to store excess power generated by abundant wind and solar PV resources. Such is the primary use case for utility-scale storage projects, including California''s Moss Landing site which is currently the country''s largest at 750MW.
Off-Grid in the Suburbs
11 May, 2023. Being Independent. Going ''off the grid'' for your energy needs means relying solely on self-generated sources of electricity, without any connection to the utility grid. While this lifestyle is very appealing, it can be challenging to achieve, particularly for those living in dense suburbia who are already connected to the grid.

Can you go off-grid with solar and energy storage?
The short answer to this question is that unless your electricity usage is minimal (around 5-15 kilowatt-hours per day), it''s not very easy to disconnect from the grid and still have all the comforts (and/or necessities) you''re accustomed to. Even with the cost of solar and energy storage falling, installing batteries really still only ...
