Microgrids
Microgrids combining local generation, storage and controls
Microgrids combine local generation, battery storage, and control systems to supply power independently or alongside the grid. They are used where reliability, fuel cost, or grid access are constraints.
Systems can operate grid-connected, islanded, or fully off-grid depending on site requirements.

Microgrids for independent site operation
How microgrids operate in each mode
-
1On-site generation (solar, wind, or other sources) provides primary energy where available
-
2Battery storage captures excess generation and supplies power during deficits
-
3A central controller manages generation, storage, and load balancing in real time
-
4Dispatchable generation (typically diesel or gas) provides backup when required
-
5The system operates in grid-connected or islanded mode depending on site conditions
Typical configuration envelope
Microgrids are designed around load profile, generation availability, and required reliability. Renewable generation reduces fuel consumption but is intermittent; battery storage provides short- to medium-duration balancing and stability; dispatchable generation ensures reliability during low renewable output. Full renewable operation is possible in specific cases, but most systems retain backup generation for reliability.

Microgrid – Deployment Case Study
A remote mining operation relied on diesel generation for a continuous ~2 MW load, resulting in high fuel costs and exposure to supply disruptions.
A hybrid microgrid was deployed, integrating solar generation, battery storage, and existing diesel generation under a central control system.
- Diesel consumption reduced substantially (site and solar resource dependent)
- Reduced exposure to fuel supply disruptions
- Improved system stability and operational reliability
Plan your microgrid operating modes
Start with the loads, available generation and required islanded duration. Then define how the microgrid will transition between grid-connected and islanded operation. Microgrids also need a coordinated plan for recharge, operating reserves and restoration after an outage.
