What to Look for in Microgrid Storage
- Islanding capability - Seamless transition to off-grid operation during outages.
- Controls and software - Coordinating generation, storage, and loads in real time.
- Configurability - Sizing storage to local generation and critical loads.
- Operations support - Many sites benefit from managed or operated solutions.
Frequently Asked Questions
What is a microgrid battery storage system?
A microgrid battery storage system stores energy locally so a microgrid can balance on-site generation and loads, and continue operating independently from the main grid during outages or planned islanding.
How does storage help a microgrid?
Storage smooths variable renewable output, supplies power when local generation is insufficient, and enables a microgrid to island, keeping critical facilities running without grid power.
Can I deploy a temporary microgrid?
Yes. Rental, plug-and-play systems such as Aggreko's can establish temporary or rapidly deployed microgrids for events, construction, disaster recovery, or remote operations.
