Energy Storage Solutions
Flexible, scalable Energy Storage solutions that support both stationary and mobile applications. With deep engineering expertise and advanced energy control software, we design and deliver complete BESS systems—from concept and procurement to construction and commissioning.
Stationary Energy Storage
BQ-G Modular battery energy storage system (BESS) is poised to play a key role in the transition to a more sustainable and renewable energy future.
Grid-scale energy storage solutions provide several benefits:
- Highly flexible and scalable solution.
- Provides grid stability and balance.
- Prevents fluctuations and maintain stable power supply.
- Stores excess energy and release when needed.
- Reduces number of traditional power plants run by fossil fuel.
- Reduce greenhouse gas emissions
