What 3 ETAP Enerji İnşaat does
3 ETAP Enerji İnşaat Sanayi ve Ticaret Ltd. Şti is a privately held Turkish engineering, procurement, and construction (EPC) contractor specializing in high-voltage energy transmission infrastructure. Founded on June 18, 2012 in Ankara by an experienced team that reconvened from a prior operating entity, the company designs and builds 154 kV and 380 kV overhead transmission lines, 34.5 kV medium-voltage distribution lines, and primary/secondary substation (transformer center) works, alongside low-voltage electrical works, OPGW (optical power ground wire) lines, and fiber-infrastructure cabling. Engineering consulting and project supervision complement the construction offering.
The company serves three core customer groups: Turkish state-owned transmission system operator TEİAŞ and private energy utilities; independent renewable energy producers (wind/RES, geothermal/JES, hydro/HES) requiring grid-connection lines; and international energy operators — most notably Karadeniz Holding / Karpowership — for which it executes transmission and substation works across Africa (Sierra Leone, Guinea, Senegal, Guinea-Bissau, Gambia, Ghana, Mozambique), the Middle East (Lebanon, Iraq), and Asia (Myanmar, Indonesia), with additional exposure in Cuba. It also performs smaller campus and real-estate-adjacent electrical and fiber works (Ordu University, DKC/SAF Gayrimenkul).
Revenue is generated project-by-project through competitive bidding on public and private tenders, with pricing determined per project scope (voltage level, line length, terrain, materials). The company is ISO 9001, ISO 14001, and ISO 45001 certified, has 11–50 employees, and operates from its headquarters in Ankara's Söğütözü business district. Revenue, ownership structure, and financial metrics are not publicly disclosed.

3 ETAP Enerji İnşaat competitors and assessment
Company assessmentOthers
- Prysmian Group: Global cable and conductor manufacturer whose products (HV conductors, OPGW, underground cables) are core inputs to 3 ETAP's projects. Comparable as an adjacent infrastructure player rather than a direct EPC competitor.
Broad incumbents
- Kalyon İnşaat: Diversified Turkish EPC active in HV transmission, substations, and renewables. Competes with 3 ETAP on TEİAŞ and IPP tenders, typically with bundled construction-plus-equipment offerings.
- Hitachi Energy: Global leader in HV substations, HVDC, and grid integration. Comparable in substation and grid-connection scope but functions as an OEM/turnkey technology provider rather than a pure transmission-line construction contractor.
- Siemens Energy: Global incumbent in HV transmission equipment and grid solutions, including substations and HVDC. Overlaps with 3 ETAP on the substation side of projects but typically acts as equipment supplier or turnkey contractor on much larger tenders.
- ENKA İnşaat: One of Turkey's largest EPC contractors with substantial HV transmission line and substation work, including turnkey international projects. Competes with 3 ETAP for utility tenders globally while also serving oil & gas and power generation clients.
- Kolin İnşaat: Major Turkish EPC contractor with substantial energy transmission line and substation capabilities. Directly competes with 3 ETAP on TEİAŞ public tenders but at materially greater scale, financial capacity, and project diversification.
- Çalık Enerji: Turkish energy EPC with international footprint spanning transmission and generation in CIS, Middle East, and Africa. Comparable in international HV transmission EPC execution but operates at significantly larger scale with an integrated developer role.
- Limak İnşaat: Large Turkish construction group with an active energy and HV transmission EPC portfolio. Comparable in that it competes for the same TEİAŞ 154/380 kV tenders, but operates across airports, dams, and other infrastructure segments as well.
- Yapı Merkezi İnşaat: Turkish EPC with track record in HV transmission, substations, and rail electrification. Competes in similar public-tender markets while operating at substantially larger scale and project diversity.
Direct peers
- Şa-Ra Enerji İnşaat: Turkish specialist EPC focused on energy transmission lines and substations. Closely comparable to 3 ETAP in scope (HV overhead lines, transformer centers) and customer base (TEİAŞ, private energy producers), though typically operating at a slightly larger scale.
