Critical power equipment systems that simplify your operations.

Utilities choose Concentric for one reason: one partner covers everything. Batteries, chargers, DC power, racking, engineering, installation, testing, maintenance, and repair, all from a single source. That eliminates the cost and complexity of managing multiple vendors across substations.

With 25+ years of experience, a national service footprint, and 100+ engineering and service professionals, we respond fast to urgent needs and support long-term modernization planning. The result: fewer vendor handoffs, faster response times, and infrastructure that holds up through regulatory changes, demand spikes, and supply chain pressure.

With 25+ years of experience in stationary power and ESS support, we install approximately 35,000 batteries annually across utility, industrial, and commercial sites, covering everything from battery installation and monitoring to full multi-site backup power modernization.

In one multi-year partnership, we helped a Northeast utility phase its backup power upgrades across multiple sites, balancing CAPEX constraints while keeping substation systems current and compliant. That phased model is how we approach utility substation power projects nationwide.

Match your battery chemistry, charger capacity, and monitoring setup to your substation's load profile, discharge requirements, and compliance needs. We offer lead-selenium options, the LSe flat plate and OPzS tubular plate, alongside the MSR and Mesa ONE industrial chargers, each suited to different utility grid backup scenarios.

Three factors drive the decision:

• Discharge duration and load: LSe flat plate batteries handle shorter, high-rate discharges; OPzS tubular plate batteries support the longer backup durations typical in utility substations.
• Charger reliability: Continuous-duty applications need chargers built for it, like the MSR and Mesa ONE.
• Monitoring visibility: Battery monitoring flags degradation early, giving substation teams time to act before a string fails.

Our engineering team evaluates each of these factors on-site and recommends the right combination for your substation backup power needs.

Multi-site modernization works best when upgrades are sequenced by risk, budget cycle, and equipment age, not replaced all at once. The constraints are real: more infrastructure needs than available CAPEX, longer supply chain lead times, and compliance requirements that shift mid-project.

A phased approach lets you address the highest-risk substations first and spread cost across multiple budget cycles. We help utilities plan around supply chain lead times in advance, including mobile battery trailer (MBT) options that keep substation power protected during a planned transition, without forcing a single-year capital outlay.

Continuous battery monitoring tracks cell voltage, internal resistance, and temperature trends across a string, catching degradation early, before it causes an unplanned substation outage.

We pair that monitoring with scheduled testing, maintenance visits, and repair services, delivered by our national team of 100+ engineering and service professionals. The result: longer battery life, lower risk of backup failure during a grid event, and a data-backed view of infrastructure health across every site.
