Lahmeyer International Gmbh

What Lahmeyer International Gmbh does

Lahmeyer International GmbH is a German consulting engineering firm founded in 1966 and headquartered in Bad Vilbel (registration: Handelsregister 80852, Registergericht Frankfurt am Main). The firm delivers planning and consultancy services for complex infrastructure projects across the full project lifecycle — from development and feasibility through design, contracting, implementation, and operation. Its practice spans four domains: Energy (conventional thermal power, transmission and distribution including Battery Energy Storage Systems, renewables, and energy transition advisory covering green hydrogen and green molecule technologies); Hydropower (design and construction, electro-mechanical equipment services, pumped storage); and Water Resources (multi-purpose water use planning, climate adaptation, flood protection, integrated river basin development). Underlying engineering tooling includes BIM (Building Information Modeling) for planning and design of hydropower and infrastructure assets.

The company serves four primary client segments — utilities and energy companies, private investors and project developers, lenders and financial institutions (technical due diligence), and government/public sector entities in developing and emerging countries. Customer engagements are large, project-based consulting mandates; notable references include the Goldisthal pumped storage project (1,060 MW) for Vattenfall Europe, Tanahu Hydropower (140 MW) for the Government of Nepal, Laúca Hydropower (2,070 MW) for the Government of Angola, Merowe Dam (1,250 MW) for the Government of Sudan, Mubarak Pumping Station (288 MW) for the Government of Egypt, the Mahaweli Water Security Investment Program for the Government of Sri Lanka, and the Gulf of Suez Wind Farms for the Government of Egypt. Go-to-market is enterprise field sales driven by international tendering and direct engagement.

Since January 2026, Lahmeyer International has operated as part of the Dornier Group, an infrastructure services conglomerate. The integrated portfolio now spans Power & Heat, Hydro, Renewables, and Mobility. The firm holds ISO 9001:2015, ISO 14001:2015, ISO 45001:2023, and ISO 37001:2016 certifications (TÜV NORD), DAkkS accreditation (D-PL-11121-01-00), IDW PS 980 compliance, UN Global Compact and ILO commitments, and is a member of the International Hydropower Association. Leadership comprises CEO Petrus Plug and CFO Patrick Pascal Rauh; Dr. Patric Kleineidam heads the Renewable Energy department.

Core offering

Lahmeyer International GmbH is a consulting engineering firm providing planning and consultancy services for complex infrastructure projects across energy, hydropower, and water resources sectors.

Direct peers

• Tractebel (Engie): Tractebel is the consulting engineering arm of Engie and a direct competitor in hydropower, energy infrastructure, and water resources consulting. It shares Lahmeyer's full project-lifecycle model (development through operation) and serves similar utilities, developers, lenders, and governments globally.
• COWI: COWI is a Danish engineering consultancy with deep hydropower, water resources, and infrastructure capabilities, including owner-engineer and lender advisory roles comparable to Lahmeyer's offering across emerging and developed markets.

• Stucky (Gruner): Stucky, now part of Gruner, is a Swiss specialist in hydropower and hydraulic engineering consulting. Its niche focus on dams, hydro plants, and water resources engineering makes it a tightly comparable peer for Lahmeyer's hydropower business.
• Norconsult: Norconsult is a Norwegian multidisciplinary engineering consultancy active in hydropower, energy, and water. It competes with Lahmeyer on international hydro and renewables advisory, especially in emerging markets where Norwegian firms have a strong presence.
• AFRY (formerly Pöyry): AFRY is a Nordic-headquartered engineering, design, and advisory firm with a strong hydropower, renewable energy, and transmission practice. It is one of the closest direct competitors to Lahmeyer in hydropower owner's engineering and energy transition advisory worldwide.
• Fichtner: Fichtner is a German independent engineering consultancy specializing in energy infrastructure consulting—generation, transmission, and renewables—closely matching Lahmeyer's core German-origin consulting engineering profile.

Regional players

• Burns & McDonnell: Burns & McDonnell is a US-headquartered engineering consultancy with strong generation, transmission, and renewables practices. It represents a comparable full-lifecycle energy engineering model, although it primarily serves North American clients rather than Lahmeyer's emerging-market focus.

Broad incumbents

• AECOM: AECOM is a global infrastructure consulting firm whose Water, Energy, and Environment practices directly overlap Lahmeyer's hydropower, water resources, and energy advisory offerings across all project phases.
• WSP: WSP is a global engineering professional services firm with a broad Power & Energy practice. It is larger and broader than Lahmeyer but competes for the same hydropower, transmission, and energy transition mandates worldwide.
