Built much closer to end-users, if not on-site, and equipped with combined heat and power (CHP) technology, microgrids are typically more efficient than centralized power generation and distribution systems. Often making use of renewable energy resources, they're also emissions-free, or at least significantly less polluting, than traditional fossil fuel-fired power generation.
More frequent and longer lasting power outages due to more frequent and extreme weather events and aging power infrastructure are also fueling interest and investment in microgrid technology and deployments. Boosting infrastructure spending, in turn, means more jobs and rising personal income.
Furthermore, growth in residential solar PV installations has driven growth and the emergence of power “prosumers.” That, in turn, is resulting in growing public interest in, and calls on government leaders, to institute industry and market reforms that support power production at the homeowner scale, such as net metering.
Adding to these benefits is microgrids' flexibility in terms of use. This extends across: primary or quick-start back-up generation, emergency recovery, load shifting, peak shaving and ancillary grid services, such as frequency and voltage regulation.
Though small, highly fragmented and posing numerous challenges to developers, the North American microgrid market is growing fast, Navigant highlights in its “Multi-client Microgrid Study.”
At present, campus/institutional microgrids account for the largest segment of the market. Growth is expected to accelerate in the utility microgrid segment as states continue to enact policy and regulatory reforms in order to meet power infrastructure needs.
Similarly, community microgrids are also growing rapidly in order to enhance grid resiliency in the face of climate change, as well as realize associated social and environmental advantages and benefits.
The microgrid benefits everyone by creating cleaner, more resilient communities. The bulk power system can also benefit from microgrid flexibility.
Frequently asked questions
What are the main benefits of a microgrid?
Microgrids deliver three core benefits: resilience, because they can 'island' from the main grid to keep critical loads powered during outages; cost savings, through peak shaving, energy arbitrage and avoided capacity charges; and decarbonization, by integrating renewables and combined heat and power. Many operators pursue all three at once.
How does a microgrid improve resilience during power outages?
A microgrid can disconnect, or 'island,' from the utility grid and run on its own generation and storage, keeping hospitals, campuses and other critical facilities powered through storms and grid failures. This matters because roughly 80% of major US power outages from 2000-2023 were weather-related, according to Climate Central, and such events are becoming more frequent.
Do microgrids actually save money?
They can. Beyond avoiding the cost of outages, microgrids monetize value streams such as reduced peak-power costs, capacity-charge reductions, energy-price arbitrage and demand-response ('negawatt') payments. Falling battery prices are improving the economics further, with BloombergNEF reporting 2025 stationary-storage costs near $70/kWh.
Are microgrids good for the environment?
Generally, yes. Because microgrids are built close to end users and often pair renewables with combined heat and power, they tend to be more efficient and less carbon-intensive than centralized fossil-fuel generation. They also make it easier to integrate rooftop solar and battery storage at the community scale.
How fast is the microgrid market growing?
Quickly. Operational US microgrid capacity has grown at roughly a 32% annual rate, reaching about 8.6 GW by the end of 2023, per Wood Mackenzie. Commercial market-research estimates suggest the global sector could roughly double this decade, to somewhere near $95 billion by 2030.
Why are data centers driving microgrid demand?
Surging, quality-sensitive electricity loads — led by AI data centers — are pushing operators toward on-site microgrids for reliable, controllable power. The IEA projects global data-center electricity demand will more than double by 2030 to around 945 TWh, with US data centers accounting for nearly half of US electricity-demand growth this decade.
