A New Era for Organized Industrial Zones: Transforming Power Infrastructure in Türkiye

Power infrastructure in Türkiye's organized industrial zones (OIZs) is being modernized because aging substations, insufficient cable capacity and a lack of digitalization directly affect the competitiveness of the manufacturers located there. Across Türkiye, OIZs are upgrading their distribution infrastructure, from substations to protection and monitoring.

OIZs are a distinctive feature of Turkish industry: planned industrial estates in which many manufacturers share common infrastructure. Many OIZs operate their own electricity distribution networks under a distribution license from EMRA (the Energy Market Regulatory Authority, known locally as EPDK), which makes the OIZ administration directly responsible for the reliability of the network that feeds its tenants.

As production grows and new facilities with heavy loads, sensitive process equipment or rooftop solar plants move into the zones, networks designed for an earlier generation of industry reach their limits. Outages and power quality problems translate directly into lost production, which is why modernization has become a strategic priority rather than routine maintenance.

Next-generation power infrastructure investments cover digital protection relays, remote monitoring systems and smart grid technologies. This transformation minimizes energy losses while safeguarding production continuity for the businesses in the zone.

In practice, this typically means renewing transformer substations and MV switchgear, replacing electromechanical relays with digital protection relays that can be selectively coordinated and read remotely, and integrating substations and feeders into a SCADA system so that faults can be located and isolated quickly. Reactive power compensation, power quality improvement and metering infrastructure that gives the OIZ administration visibility into consumption complete the picture.

Because OIZ networks feed factories that are already running, modernization is usually executed in phases. Switching sequences and temporary supply arrangements are planned in advance so that each tenant's downtime is kept to a minimum and the network stays selective and safe at every intermediate stage.

Miratek Elektrik takes an active role in power infrastructure modernization projects in OIZs across Türkiye, managing critical processes such as transformer substation renewal, MV switchgear installation and SCADA integration end to end.

Our track record includes 120 MVA of total transformer capacity, 85 km of MV/LV cable lines and 48 MV switchgear cubicle installations across the 1–35 kV range. We also support OIZ administrations with engineering consultancy, from design approval to OIZ electricity distribution license processes, so that technical and regulatory work moves forward together.
