Howard Industries
Mississippi manufacturer of distribution and power transformers. Its June 2026 catalog lists power units up to 300 MVA and 345 kV, plus data center distribution units up to 20 MVA.
Facts
Source per value- Segment Power when the maker publishes power, GSU, HVDC, autotransformer or reactor products or a rating above 20 MVA; Distribution when it publishes distribution, pad-mount, pole-mount, network or dry-type products; both when it publishes each. Derived from Transformer types and Largest rating.
- Power and distribution 4
- Transformer types Product types the maker lists, separated by semicolons: power, GSU, autotransformer, HVDC, shunt reactor, substation, distribution, pad-mount, pole-mount, network, dry-type (cast resin, VPI), mobile, rectifier/industrial, renewable and data center lines.
- distribution; pad-mount; pole-mount; network; substation; mobile 4
- Largest rating MVA Largest verified published rating in the cited product or regional scope, in MVA. Product range identifies base, forced-cooling, phase-shifter throughput or group-history claims; these rating bases are not interchangeable. Planned future ranges are described separately.
- 300 5
- Smallest rating kVA Smallest published rating, in kVA. Shows how far down the distribution range a maker goes.
- Not published
- Product range The kVA/MVA range as the maker states it, by product line.
- June 2026 catalog: medium and large power transformers up to 300 MVA; distribution transformers up to 20 MVA 5
- Highest voltage kV Highest voltage class the maker publishes or has delivered, in kV (AC system voltage; HVDC noted under Voltage classes).
- 345 5
- Voltage classes Voltage classes and BIL as the source states them, by product or plant.
- Power: primary through 345 kV, 1,300 kV BIL; distribution: primary through 46 kV, 250 kV BIL 5
- Plants Transformer manufacturing locations, city and country. Planned plants carry their target date. Location lists identify verified sites and may not cover every factory in a global group.
- Laurel (Jones County), Mississippi, United States; Clarke County, Mississippi, United States; Simpson County, Mississippi, United States; Mexico (new plant announced 2026-05) 1
- Plant countries Countries with verified operating transformer manufacturing in the cited scope; not necessarily the complete global footprint. Component and service-only sites do not establish new-unit manufacturing.
- United States 1
- US plant Yes when an operating US transformer plant is verified; No when the source shows the maker's plants and none is in the US. Empty means not verified.
- Yes 1
- EU plant Yes when an operating transformer plant in an EU-27 country is verified (the UK, Norway, Switzerland and Turkey do not count). Empty means not verified.
- Not published
- Capacity expansion Announced transformer capacity expansions: amount in the original currency, place, announcement date, target date and output change. US and EU projects first.
- $236.95M expansion across Clarke, Jones and Simpson counties, Mississippi, announced 2025-06, 450 jobs within five years; substation plant expansion groundbreaking 2026-04-02; new Mexico plant announced 2026-05-08 1
- Largest US/EU expansion $M Largest single announced US or EU transformer capacity investment, in US$ millions, where the source states a dollar amount. Euro amounts stay in Capacity expansion unconverted.
- 236.95 2
- Expansion region Where the announced capacity expansions are: US, EU, both, or only elsewhere (Other).
