• Shifting renewable energy to peak demand hours
• Reducing reliance on fossil-fuel peaker plants
• Supporting islanded grids and remote energy access
• Enabling more efficient energy trading and grid services
From lithium-ion battery systems to flow batteries, EV charging infrastructure, and co-located solar and storage facilities, demand for energy storage professionals is growing rapidly.
