What Imes Group does
Imes Group is a privately-held French EPC (Engineering, Procurement, Construction) contractor specializing in high-voltage electrical infrastructure. Founded in 2009 by Loic Derrien as IMES Electricité and rebranded to IMES Group in 2017, the firm delivers turnkey and vendor-neutral solutions across the HVDC (High Voltage Direct Current), Grid, and Power sectors, with documented expertise in VSC (Voltage Source Converter) and SVC (Static Var Compensator) technologies and projects spanning 20kV to 500kV plus HVDC.
The company's offering covers the full asset lifecycle through six core service lines: Project Delivery, Solution Engineering (FEED through detail design and protection cubicle manufacturing), Project Management Services, Sites Services (installation, testing, commissioning), Operation & Maintenance Services with 24/7 hotline support, and Site Survey Services. Technical differentiators include IEC 61850 protection scheme testing, end-to-end substation testing and commissioning, secondary systems engineering, and proprietary Omicron-based testing methodologies. Imes is ISO 9001, ISO 14001, and ISO 45001 certified.
Commercially, Imes operates as a B2B project-based EPC contractor serving grid utilities (RTE, KEPCO), OEM main contractors (GE, Siemens T&D, AREVA T&D, ALSTOM Grid, Schneider Electric), and renewable energy developers (Valeco France). Revenue is generated through quote-based one-time EPC turnkey contracts plus recurring professional services for engineering consulting and ongoing O&M. The firm holds multi-country offices in France (Ennery HQ, Paris, Brest, Rennes), Switzerland (Geneva), Germany (Cologne), UK (London, Stafford), and South Korea (Seoul), with a partnership covering the Baltics from Vilnius.

Imes Group competitors and assessment
Company assessmentEmerging players
- AFRY (formerly Pöyry): European engineering consultancy with strong power transmission and HVDC advisory capability serving utilities and renewable developers. Comparable to IMES in the European power engineering services market, with overlap on substation and grid connection scopes.
- Mott MacDonald: Global engineering consultancy with a strong power transmission and HV substation practice providing owner's-engineer, design and project management services. Comparable to IMES in serving TSOs and renewable developers, though typically on the consultancy side rather than as an EPC contractor.
- NKT A/S: Danish manufacturer and installer of HVDC cable systems and provider of related HV installation services. Comparable to IMES in the broader HVDC project delivery ecosystem, though focused on the cable system scope rather than converter stations and protection systems.
- Tractebel (Engie): European engineering consultancy with significant HVDC, substation and grid infrastructure expertise, part of the Engie group. Overlaps with IMES in serving European utilities and renewable developers on HV project engineering scopes.
Direct peers
- GE Vernova (Grid Solutions): GE Vernova's Grid Solutions business provides HVDC, HV substation and protection systems globally. GE is both a customer and a key competitor for IMES, operating across overlapping project scopes in transmission and renewable interconnections.
- Hitachi Energy (formerly ABB Power Grids): Hitachi Energy is the global market leader in HVDC systems and a major provider of HVDC commissioning, service and engineering solutions. It is the most direct comparable to IMES in the HVDC-VSC and grid substation space, although it operates at vastly greater scale and as an OEM rather than a vendor-neutral contractor.
- Siemens Energy: Siemens Energy is a leading OEM and EPC provider for HVDC converter stations, grid substations and HV infrastructure. Like IMES, it serves global TSOs and renewable developers; IMES in fact counts Siemens T&D among its past customers, indicating direct overlap on project scopes.
- Hyosung Heavy Industries: South Korean HVDC and HV power equipment manufacturer and EPC contractor that has executed major HVDC projects (including for KEPCO). Directly comparable to IMES's Korean operations and overlapping on the same regional HVDC pipeline.
- LS Electric: Korean HV power equipment and HVDC system provider serving KEPCO and other regional utilities. Overlaps with IMES's Seoul branch on Korean HVDC tenders and EPC scopes.
Broad incumbents
- Worley: Global EPC and engineering services provider with significant power and renewables delivery capabilities, including HV substation and grid connection work. Comparable to IMES as a multi-disciplinary EPC contractor in the energy sector, though at much larger scale and with broader scope.
