Modular Skid-Mounted Unit Substation (Step-Up / Collector)

up to 38 kV class · modular skid

Entogo modular skid-mounted step-up collector unit substation for renewables

Overview

A fully modular, skid-mounted unit substation for renewable collector and step-up (boosting) duty — cutting site footprint ~30% and design/install time ~70%, with cloud-based remote diagnostics. Up to 38 kV class, 60 Hz; designed to IEEE C37.121/ANSI C57.12.34; UL/CSA certifiable.

This modular skid-mounted unit substation provides a fully prefabricated, fast-deploy solution for renewable collector and step-up (boosting) duty. Because the all-metal cabins are factory-built, wired and tested, it cuts site footprint by roughly 30% and design, installation and commissioning time by roughly 70% versus a conventional field-built substation. It is configured as a step-up collector for solar PV, wind and battery storage, or as a step-down service-entrance substation, up to 38 kV class equipment (34.5 kV system) at 60 Hz.

Intelligent environmental control suits high-heat, high-humidity and dusty sites, with cold-climate, wind and seismic packages specified per location. Cloud-platform remote health diagnostics, fault analysis and SCADA integration enable unmanned operation and full-lifecycle equipment management. Designed and built to IEEE C37.121, ANSI C57.12.34 and IEC 62271-202, with UL (cULus) / CSA certification available on request.

Key features

FAQ

Common questions

Is this a step-up or step-down substation?
Either. It is configured as a step-up collector substation for solar, wind and battery-storage interconnection, or as a step-down service-entrance substation for industrial loads — up to 38 kV class equipment (34.5 kV system), 60 Hz.
What makes the modular skid format faster to deploy?
Because the cabins are factory-built, wired and tested, the modular skid cuts site footprint by roughly 30% and design/installation/commissioning time by roughly 70% versus a conventional field-built substation.
Which standards and certifications apply?
Designed to IEEE C37.121, ANSI C57.12.34 and IEC 62271-202, 60 Hz, with SCADA-ready remote diagnostics. UL (cULus) / CSA certification is available on request.
