| Solar-Plus-Storage Microgrid | Solar photovoltaic panels, battery storage, and often a grid connection or dispatchable backup generator. | Stores surplus daytime solar power for evening use, helps balance short-term changes in solar output, and can provide backup power when configured for islanded operation. | Commercial buildings, campuses, community facilities, and sites with good solar exposure. | Modular design, low operating emissions during solar generation, and reduced dependence on grid electricity. | Solar availability varies with weather and time of day. System sizing should reflect load patterns, seasonal conditions, backup requirements, and battery limits. |
| Solar-Wind-Battery Microgrid | Solar photovoltaic panels, wind turbines, battery storage, and optional dispatchable backup generation. | Balances mismatches between renewable generation and demand; can absorb excess generation and support the system during periods of low renewable output. | Remote communities, islands, agricultural sites, and locations with complementary solar and wind resources. | Combines two variable renewable resources that may produce at different times, potentially reducing reliance on fuel-based generation. | Wind resource, turbine siting, permitting, maintenance access, and seasonal generation patterns require site-specific assessment. |
| Solar-Battery-Diesel Hybrid Microgrid | Solar photovoltaic panels, battery storage, and diesel generators. | Provides fast-response balancing, stores solar energy, and can reduce generator runtime when renewable generation and stored energy are available. | Remote facilities, islands, mining operations, and other sites where grid access is limited or unavailable. | Combines renewable generation with dispatchable backup, supporting continuity of supply when solar output is low. | Fuel delivery and generator maintenance remain important. Controls must coordinate renewable output, battery operation, generator loading, and reserve capacity. |
| Wind-Battery Microgrid | Wind turbines, battery storage, and, where needed, a grid connection or dispatchable backup source. | Helps smooth short-term changes in wind generation, stores excess energy, and supports local loads when wind output declines. | Coastal communities, rural sites, islands, and locations with suitable and consistent wind resources. | Can make use of strong local wind resources and diversify generation when paired with other sources. | Wind measurements, turbine placement, noise and land-use constraints, maintenance logistics, and low-wind periods affect project design. |
| Small-Hydropower Hybrid Microgrid | Run-of-river or small hydropower, solar or wind generation, and battery storage; backup generation may also be included. | Provides short-duration balancing and helps manage changes in demand or renewable output. The hydropower resource may provide a more controllable supply where water flow permits. | Rural communities and facilities near suitable streams or existing small-hydropower infrastructure. | Can combine a local water resource with variable renewables and storage to diversify supply. | Water flow is seasonal and site-specific. Water rights, ecological impacts, civil works, and permitting must be evaluated. |
| Grid-Connected Renewable Microgrid | Local solar and/or wind generation, battery storage, and a connection to the wider electricity grid. | Shifts energy use, supports local balancing, and may provide backup during a grid outage if the system is designed and equipped to operate independently. | Hospitals, campuses, industrial facilities, commercial districts, and community energy systems. | Can combine local generation and storage with grid-supplied electricity; some designs can separate from and reconnect to the grid. | Islanded operation requires suitable controls, protection, switching, and interconnection arrangements. Capabilities depend on system design and local rules. |
| Renewable Microgrid with Long-Duration Storage | Solar and/or wind generation with batteries, thermal storage, pumped storage, or hydrogen-based storage, depending on the project. | Stores energy for longer periods than typical short-duration balancing applications, subject to the storage technology and system design. | Sites with extended periods of low renewable output, remote energy systems, and facilities seeking longer backup or energy-shifting capability. | Broadens storage options beyond short-duration battery applications and can support longer energy-management periods. | Technologies differ in efficiency, response time, duration, cost, safety requirements, and infrastructure needs; feasibility must be assessed for each site. |
