Torus Power Integration
Engineering, procurement and construction for solar and storage.
Torus Power Integration is an EPC for utility-scale and commercial solar and battery storage projects. We engineer, procure and build the plant, from DC collection and inverter and transformer pads to medium-voltage collection and standby generation.
EPC delivery
One contract from design to energization.
Torus Power Integration takes solar and battery storage projects through engineering, procurement and construction, with testing and documentation at each stage.
Engineering
Plant design coordinated with the owner, the equipment manufacturers and the utility’s interconnection requirements.
Procurement
Sourcing and management of major equipment, including inverters, batteries, transformers and switchgear, through delivery to site.
Construction
Construction through energization, built to the engineered design and tested before anything is energized.
Scope
What we build.
From the first trench to the utility connection, with the testing and documentation each stage needs.
Battery storage
- BESS units, PCS and DC bus landings
- AC-coupled and DC-coupled systems
- Microgrid integration
- BMS, EMS and SCADA communications
Medium voltage
- 34.5 kV collection, direct-buried and in duct bank
- Pad-mount transformer installation
- Grounding grids and exothermic connections
- Switchgear, reclosers and metering CT/PT cabinets
Standby generation
- Generator sets and automatic transfer switches
- Closed-transition paralleling switchgear
- Generator step-up transformers and bus duct
- Load bank testing
Battery storage
Battery storage, installed to code.
Every system is built to NFPA 855 and NEC Article 706, matched to the equipment’s UL 9540 listing and UL 9540A test data, and coordinated with the local fire authority.
Testing and commissioning
Capacity and round-trip efficiency (RTE) testing, fire-system interlock checks and EMS integration, verified before the system goes into service.
Controls and communications
Hardwired and fiber links between the BMS, PCS, EMS and site controller, terminated, tested and documented for commissioning.
