Overall reliability is a critical focus for utilities across North America, creating the need for solutions and equipment that can support the grid during times of emergency or occasional planned outages. Taking proactive measures to address these potential vulnerabilities is, therefore, vital to ensure a resilient network that minimizes customer interruption frequency and duration.

Southern States, with over 100 years experience integrating high voltage switching equipment, has worked to address this initiative through mobile substation designs that are specifically tailored to each customer’s unique application. Advantages of mobile substations and auxiliary trailers include immediate costs savings to a utility’s network, expedited restoration times, as well as operational flexibility when multiple location sites are impacted by severe weather or equipment damage.

Leveraging our partnership with various ISO certified transformer manufacturers, Southern States has the resources to design or retrofit mobile substations (mobile transformers) that can be outfitted with Southern States’ or your preferred switchgear brands. Available up to 230 kV and 65 MVA, our mobile products are manufactured with stringent specifications, ensuring the design is robust, durable, and to the utility’s expectations.

For additional applications, Southern States also offers auxiliary mobile solutions to support reactive power compensation, switchgear failures, as well as other utility resiliency initiatives. These include mobile capacitor trailers, mobile circuit switcher trailers, mobile circuit breaker trailers, mobile disconnect switch trailers, mobile reactor trailers, mobile recloser trailers, mobile voltage regulator trailers and mobile GIS to name a few. Each can be equipped with a variety of custom features such as racking mechanisms, hydraulic systems, turntables, fences, and much more. Let our team of experienced designers and engineers develop a solution best suited to your utility’s specification requirements. Make sure to download our mobile substation brochure to learn more!
