Battery Energy Storage Electrical Solutions
Battery Energy Storage Systems are critical to a stable, flexible grid. They store power when demand is low and deliver it when the grid is stressed, support renewables, and improve power quality for utilities and large energy users. As your electrical contractor, Benchmark Electrical Solutions provides the full Balance of System that brings a BESS to life.

Turnkey Balance of System
From underground duct banks to final terminations, we manage the entire electrical scope outside the battery enclosures. Our team installs inverters and power conversion systems, AC and DC cabling, pad-mounted transformers, medium voltage gear, and low voltage distribution so every component is connected correctly and ready for commissioning.
Medium Voltage, Protection & Utility Coordination
We design and build medium voltage systems that align with utility standards and project interconnection agreements. This includes switchgear, protective relays, metering, grounding grids, and grid-tie equipment to ensure safe and reliable energy delivery.
Safety, Controls & Auxiliary Systems
Reliable storage depends on more than batteries. We power and integrate fire detection, HVAC units, lighting, egress, security systems, and SCADA or communications networks to ensure the entire facility operates safely and meets code requirements.
Testing, Commissioning & Ongoing Support
Before the site goes live, we perform insulation resistance tests, termination checks, functional testing, and support OEM and utility commissioning teams. Our goal is a smooth energization and reliable long-term operation.
