Eser

What Eser does

Eser Taahhüt ve Sanayi A.Ş. is a privately held Turkish international contracting and engineering group founded in 1986 and headquartered in Ankara, with operational offices in Baku, Azerbaijan and a hydroelectric power generation subsidiary (Göksu Enerji A.Ş.) operating hydro plants in Cide, Kastamonu. Its core product is large-scale infrastructure delivery — roads, railways, dams, hydro power plants, water and wastewater systems, and commercial buildings (including high-rises such as the Riyadh Twin Towers totaling 240,000 m²) — executed through a design-build and turnkey EPC model. Engineering, consultancy, and dam design work is routed through the wholly-owned subsidiary ESPM ESER PROJE VE MÜHENDİSLİK A.Ş., while the Eser Green Building initiative houses TUBITAK 1501-funded R&D on intelligent exergy management and energy-efficient building automation.

Eser serves sovereign, sub-sovereign, and multilateral clients — Nigerian Railway Corporation, governments of Azerbaijan, Turkmenistan, Cameroon, Pakistan, and Saudi Arabia, and the Turkish energy grid — winning work via competitive bidding, frequently co-financed by the World Bank, Islamic Development Bank, and OPIC. Customers documented in the source set are exclusively government or government-adjacent, with no commercial or SMB counterparties. Projects are delivered either directly by Eser's construction teams or via joint ventures with local partners (e.g., Sultan Mahmood & Company on Multan Metro Bus in Pakistan). Revenue accrues through one-time construction contracts; pricing is not publicly disclosed.

The company is recognized as the 176th-largest international contractor globally in the 2014 ENR Top 250 ranking (up six positions year-over-year) and holds Gold Standard Clean Development Mechanism certification on its Berke and Ekincik hydro plants, supporting carbon-credit monetization alongside electricity sales. Marketing is driven primarily by ENR rankings, project-completion news, and participation in industry forums such as the Dams Congress and Water Structures Symposium rather than by outbound sales or paid demand generation.
