What Asplundh Engineering Services does

Asplundh Engineering Services (AES) is a privately held engineering services firm headquartered in Horsham, Pennsylvania, operating as a subsidiary of Asplundh, a diversified conglomerate with over 33,000 employees and 100+ years of utility services history. AES delivers engineering, design, planning, construction management, testing and commissioning, and full EPC (Engineering, Procurement & Construction) services for the U.S. utility industry, serving investor-owned, municipal, and cooperative electric and gas utilities, as well as large power users, government entities (including the Department of Defense), commercial/industrial clients, renewable energy developers, and transit authorities. The company's service portfolio spans ten market segments: distribution, transmission, substation, protection & control, power generation, renewable energy, commercial & industrial, transit, gas distribution, and gas transmission, with voltage capabilities ranging from 480V to 500kV and generation facility support from 10kW to 2GW. Testing and commissioning services are delivered through the wholly owned subsidiary Asplundh Electrical Testing (AET), which holds NETA certification and provides substation commissioning, acceptance testing, and maintenance services nationwide.

AES generates revenue through project-based professional services contracts and EPC delivery, with pricing determined per project via RFP and direct enterprise engagement. The company operates from 17 office locations across the United States — spanning the Northeast, Southeast, Midwest, and West Coast — enabling local responsiveness while maintaining national delivery capacity. Its technology stack is built on industry-standard power system analysis and engineering design software including EasyPower, SKM PowerTools, PSS/E, ETAP, ASPEN OneLiner, PLS-CADD, AutoCAD, Civil3D, Plant3D, and AVEVA. AES differentiates on the basis of safety credentials (ISO 45001 certification, OSHA ET&D Strategic Partnership membership, industry-leading TRIR/EMR rates), NERC compliance expertise, in-house protective relay panel design and fabrication, and the ability to offer a single-entity EPC solution that eliminates the need for clients to coordinate multiple contractors. The company holds no public ticker, has no venture capital or institutional investment rounds, and operates as part of the Asplundh family of companies under unified private ownership.
