What Electrical Reliability Services does

Electrical Reliability Services (ERS) is a US-based field services firm specializing in electrical power system testing, commissioning, maintenance, and engineering for critical infrastructure. The company employs ANSI/NETA-certified engineers and field technicians to deliver acceptance testing, maintenance testing, preventive and predictive maintenance, transformer services, arc flash studies, single-line diagrams, protection and controls, relay upgrades, DC power (battery/UPS) services, and NERC compliance support. ERS also provides building commissioning, complex project management, 24/7 emergency response, and NFPA 70E/70B-aligned training services. The technical scope spans electromechanical, solid-state, and microprocessor-based relays through to IEC 61850 IEDs, distributed protection, and automation logic controls.

ERS serves data centers, electric utilities, industrial and manufacturing facilities, commercial buildings (including hospitals and institutional facilities), wind and solar renewable generation, water and wastewater treatment, electric vehicle (EV) charging infrastructure, and battery energy storage system (BESS) installations. The company operates through direct enterprise field sales, deploying certified technicians from a national network of regional office locations across the United States, enabling both multi-site rollout and rapid single-site response. ERS is a wholly owned subsidiary of Vertiv Holdings Co. (NYSE: VRT); its website is hosted at ers.vertiv.com and its support operations route through Vertiv's sales cloud.

Revenue is generated through quote-based, custom-scoped engagements — primarily project-based professional services for commissioning and acceptance testing, supplemented by recurring preventive and predictive maintenance contracts structured as multi-year agreements. Customer acquisition is supported by industry content marketing, webinars, tradeshow participation, customer stories, and a Resource Center, complemented by named-account recognition such as the QTS 2024 Partner & Innovation Summit (Commissioning Agent of the Year, Gold Honor) and Highwire's Platinum Safety Award.
