ANSI/IEEE C57 Market
Power Infrastructure
in United States.
ETS manufactures UL-listed pad-mounted, ANSI/IEEE-compliant power transformers and ANSI-rated switchgear across all 50 states. North American sales operations are based in Gaithersburg, MD with focus on data-center, renewable PV and utility infrastructure procurement.
Market context
Grid topology, regulation & demand drivers.
The US transformer market is the largest globally, structured around three RTO/ISO regions — PJM (mid-Atlantic), MISO (midwest) and ERCOT (Texas) — plus the Western Interconnection's CAISO and the Eastern Interconnection's NYISO and ISO-NE. Procurement runs through three distinct utility models: investor-owned utilities (IOUs) like Duke Energy, Southern Company and Dominion; municipal and public power agencies; and ~900 rural electric cooperatives. Pad-mounted distribution transformers (200 kVA–5 MVA) and substation power transformers (10–500 MVA) follow ANSI/IEEE C57 standards, UL 506 listings and DOE 10 CFR 431 efficiency mandates (Tier 2 effective 2027). Voltage levels are 12.47/13.8/24.94/34.5 kV at MV and 69/115/138/230/345/500/765 kV at transmission. Demand is driven by an unprecedented data-center buildout in Northern Virginia (PJM Dominion zone), Texas (ERCOT), Phoenix and Atlanta — projected to add 100 GW+ of load by 2030 — plus IRA-funded utility-scale solar and storage in California, Texas and the Southeast. Permitting bottlenecks and 2–3 year lead times for power transformers from incumbent OEMs have created severe procurement pressure. ETS sales operate from Gaithersburg, MD with UL-listed pad-mounted units shipped from our ISO 9001 manufacturing facility via East-Coast container ports, addressing the supply gap.

Frequently Asked Questions — United States
Lead times for projects in United States depend on the specification, scope of supply, order volume and prevailing factory load. Distribution transformers (11–33 kV, up to 5 MVA) typically build and test faster than power transformers (33–132 kV, up to 60 MVA), and EHV units above 132 kV require the longest manufacturing and testing windows. Every quoted programme includes witnessed Factory Acceptance Testing at our Jebel Ali high-voltage lab and agreed delivery terms, across the 38 cities we serve in United States. Please contact ETS with your technical schedule for a project-specific delivery plan.
