Ertek Mühendislik San. ve Tic. Ltd. Şti. is a privately held Turkish electrical engineering services company founded in 1989 by Erol CELEPSOY and headquartered in Kadıköy, Istanbul. The firm delivers end-to-end low, medium, and high voltage (up to 154 kV) electrical infrastructure services, including transformer and distribution center installation, energy transmission line construction, project design and consulting, and high voltage operation responsibility services required under Turkish EMO regulations for facilities operating above 1 kV. It also operates a complementary transformer maintenance, testing, and oil treatment capability supported by specialized equipment (AÖM-02 oil purification machine, Vanguard CT-3500, Vanguard WRM-10P, Fluke TI300, Metrel Tera Ohm XA 10 kV, B2 75 kV breakdown analyzer) and provides demand and subscription management with electricity providers. The company holds ISO 9001, ISO 14001, and OHSAS 18001 certifications accredited by TÜRKAK, and operates a group affiliate, ERCE Enerji Sistemleri, offering adjacent energy systems services.

The customer base is enterprise-weighted and vertically diverse, spanning industrial manufacturing (Aslan Çimento), data centers (Equinix, Zenium/Kent Development), commercial real estate (Zorlu Center, Mesa), retail (Migros, ŞOK Marketler), telecommunications infrastructure (TEİAŞ), media (Hürriyet), technology (Microsoft Turkey), education (Yeditepe Üniversitesi), defense (Tuzla Piyade Okulu), and municipal government (Kadıköy Belediyesi). The go-to-market is direct enterprise field sales across Turkey with 24/7 emergency response, and the revenue model blends professional services (project contracting, consulting, maintenance), managed services (high voltage operation responsibility), subscription-style revenue (demand and subscription administration), and hardware/material supply on project delivery. Pricing is not publicly disclosed and is set on a project-by-project, custom-quote basis.

Broad incumbents

• ABB: ABB manufactures transformers, switchgear, drives and substation automation and offers installation and service across the same product categories Ertek specifies and installs; Ertek is essentially a Turkish specialist systems integrator riding on ABB-class equipment.
• Schneider Electric: Schneider Electric's Energy Management segment covers MV/LV distribution, transformer services and electrical infrastructure lifecycle services — overlapping with Ertek's full voltage-scope services but at global scale.
• Eaton: Eaton provides power distribution, transformer, switchgear and electrical service solutions used in the same industrial and data center settings Ertek serves, making it a competing OEM-plus-services incumbent.

Direct peers

• MYR Group: MYR Group's transmission and distribution business builds and maintains HV substations, transmission lines and industrial electrical infrastructure — directly comparable to Ertek's MV/HV installation and maintenance offering.
• Quanta Services: Quanta Services is one of the largest utility-focused electrical infrastructure contractors, performing HV transmission, substation and transformer services for utilities and industrials — the same core services Ertek delivers to TEİAŞ, Equinix and Turkish industrials.
• Faith Technologies: Faith Technologies is a large electrical contractor offering design, build, maintenance and 24/7 service across commercial, industrial and mission-critical facilities — closely aligned with Ertek's enterprise field-sales, multi-segment service model.
• MMR Group: MMR Group performs electrical construction, instrumentation and maintenance for industrial, utility and data center customers, comparable to Ertek's industrial and data center HV contracting and predictive maintenance work.
• IES Holdings: IES provides commercial and industrial electrical contracting including design-assist, installation and maintenance, mirroring Ertek's mix of low/medium voltage contracting plus ongoing service contracts.

Regional players

• ENKA İnşaat: ENKA is a Turkish EPC contractor executing power plants, substations and HV infrastructure domestically and abroad; it competes with Ertek on large Turkish HV tenders and represents a potential regional roll-up target.
• Enerjisa: Enerjisa operates electricity distribution, retail and generation businesses in Turkey and procures HV contracting and maintenance services similar to those Ertek delivers to TEİAŞ-adjacent customers.
