Battery Energy Storage Systems
Transformers and electrical equipment matched to battery energy storage system (BESS) interconnection and power-conversion requirements.
Overview
Grid-scale and behind-the-meter battery energy storage systems place high power-density, fast-response demands on their interconnection transformers. We coordinate transformers and related electrical equipment engineered for these characteristics through our manufacturing network, matched to your PCS (power conversion system) configuration.
Technical Considerations
PCS (power conversion system) output voltage and rated capacity
Fast charge/discharge cycling and overload tolerance
Step-up voltage ratio to the interconnection point
Enclosure and thermal management for containerized BESS units
Grid code compliance for the interconnection point
Harmonic performance under fast switching conditions
Exact specification is confirmed against your project's PCS datasheet and SLD — available upon project requirement.
Applicable Standards
Products can be supplied and tested in accordance with applicable IEC, IEEE/ANSI, CSA, GOST and destination-market requirements, subject to product type and manufacturing partner.
Customization Options
Voltage ratio, thermal design and enclosure configuration can be adapted to your PCS and container layout through our manufacturing partners — confirmed per project.
