What Atlantic Plant Maintenance does

Atlantic Plant Maintenance (APM) is a US-based construction and maintenance services firm specializing in skilled craft labor for power generation outages. Founded in 1975 and headquartered in Pasadena, Texas (adjacent to Houston), the company operates under the corporate parent Viceroy, Inc. APM deploys craft professionals drawn from a 40,000+ person union labor pool — primarily through partnerships with the United Brotherhood of Carpenters — to execute planned and unplanned outages at gas, steam, nuclear, boiler, and renewable power facilities across the Americas. The company completed integration into the GE/Alstom power services portfolio in 2015 and now maintains a US/Canadian corporate structure (APCom Power, Viceroy Canada, API Canada, GETSCO Technical Services) with operations spanning US regions (North, South, West) and an Edmonton-based Canadian hub, plus a Middle East presence in Israel.

APM's service portfolio is organized across eight divisions: Gas Power, Rigging & Renewables, Oil & Gas and Aero, Specialty Services, Steam Fossil, Steam Nuclear, Boiler (US and Canada), and APM Canada. These divisions cover maintenance, inspection, and upgrade services across major turbine and generator OEM platforms (GE, Alstom, Siemens, Toshiba, Mitsubishi), as well as ASME/NBIC-certified boiler and pressure vessel work. The Leadership Development Center (LDC), an 80,000 square foot training facility in Pasadena, TX with the largest 75/75 ton crane in the Houston area, serves as the workforce development backbone. APM executes 1,000+ jobs and 3M+ manhours annually (2.6M+ hours across 1,200+ jobs in H1 2024 alone).

The business model is professional services, with revenue generated through billable craft labor hours and project-based turnkey outage execution. Pricing is quote-based and negotiated by union jurisdiction and labor class (24-hour standard quote turnaround, extending to 48–72 hours for new union/class combinations). Customers are enterprise power generation operators including NextEra Energy, Dominion Energy, Calpine, Puget Sound Energy, SMUD, TransAlta, Capital Power, and Southern Company (Plant Vogtle). Distribution is through direct regional field sales with dedicated Operations Division Managers, supplemented by the apmdelivers.com website and regional request-manpower forms. Safety, quality documentation, and regulatory certifications (ASME stamps A/PP/S/U, NBIC R Stamp #3, CSA Category A–H) are central to the value proposition and constitute significant barriers to entry for competitors.
