Türkiye’s Energy Market Regulatory Authority, known as EPDK, has outlined new targets for the digital transformation of electricity distribution under the National Smart Meter System, or MASS. According to figures announced by EPDK Chairman Mustafa Yılmaz on October 26, 2026, about 2.7 million Smart Meter PRO units are planned by the end of 2027. Over the two-year programme, the regulator aims to bring roughly seven million subscriber meters within remote-reading coverage. These figures are targets, not completed installations.
Transformation began on March 1
Yılmaz said deployment of meters developed under MASS began on March 1, 2026. By the end of September, four million Smart Meter EKO units and 70,000 Smart Meter PRO units had been installed. The regulator’s stated principle is to extend the new system to the largest possible number of meters at the lowest feasible cost.
The next stage calls for approximately 2.7 million PRO models to be installed by the end of 2027. Working alongside EKO units, the wider system is expected to make consumption readings remotely accessible for around seven million subscribers. The seven-million figure therefore refers to the planned subscriber reach of the system, not only to the number of new PRO meters.
Quality monitoring at 15 million connection points
The programme is intended to do more than collect consumption data for billing. Yılmaz said outage and technical-quality information would be monitored at the connection points of 15 million subscribers. He described MASS as a platform that could support fault prediction, risk-based maintenance, efforts against electricity losses and stronger network resilience during disasters through remote communications and grid data.
Whether those goals are achieved will depend on the installation pace of distribution companies, the deployment of different communications methods and interoperability across the system. Yılmaz said EPDK would monitor meter replacements and take measures concerning companies that fall behind the plan. The announcement did not provide company-by-company schedules or specify which provinces or neighbourhoods would be converted first.
Test version of the MASS mobile application
A test version of the MASS user application has also been released alongside the meter programme. According to the announcement, the application is intended to let electricity subscribers in Türkiye access consumption and generation data, outage records, compensation information and notices of planned interruptions. Its description as a test version means features and the user experience may still change during development.
Remote reading can allow meter data to reach the distribution infrastructure without requiring a worker to visit each meter physically. Practical details—including when individual households will enter the programme, how replacements will be conducted and how accounts will be accessed in the application—will need to be clarified through official notices from distribution companies and EPDK. The regulator’s announcement does not assign an installation date to every subscriber.
Part of a wider grid investment programme
Yılmaz placed the smart-meter target within a broader programme of electricity-distribution investment. He said growth in renewable generation, electric transport, storage and distributed production was changing how networks operate, while digitalisation was reshaping fault detection and maintenance. For the 2026–2030 regulatory period, he said EPDK increased the investment ceiling by about one and a half times in real terms and raised planned-maintenance resources by 2.1 times.
The target does not mean every electricity meter in Türkiye will be remotely readable by the end of 2027. The stated plan covers about seven million subscribers for remote readings and 15 million connection points for outage and technical-quality monitoring. Customers should rely on EPDK, their electricity distribution company and official MASS channels for information about meter replacement or access to the application.
