HEDNO (Hellenic Electricity Distribution Network Operator) is accelerating the program to replace old electricity meters with modern smart meters, aiming to complete the mass installation within 2026. This ambitious project is part of the broader digital transformation of the electricity distribution network in Greece.
🔎 What Are Smart Meters?
Smart meters are digital devices that replace traditional analog electricity meters. Unlike old meters that required manual readings, the new meters automatically transmit consumption data to HEDNO in real time.
📡 New Technology: HEDNO utilizes NB-IoT (Narrowband Internet of Things) and LTE-M technologies for connecting smart meters, ensuring reliable and low-power communication.
🔍 NOVA Takes on Connecting 1,000,000 Meters
In a major development, NOVA was selected as the contractor for the largest smart meter connectivity project in Greece. The project involves connecting 1,000,000 smart meters to the network, marking a huge step toward digitizing the energy sector.
✅ Benefits for Consumers
The installation of smart meters brings significant advantages for consumers:
- Accurate billing: No more estimated consumption and surprise bills
- Consumption monitoring: Real-time energy consumption tracking capability
- Dual-zone pricing: Better utilization of low-tariff periods (night-time electricity)
- Fast fault detection: HEDNO is immediately notified of outages and problems
- No more manual readings: No need to report readings or wait for a meter reader
🔎 Issues and Challenges
However, the program also faces certain challenges. According to reports, there have been cases where the new meters exhibit operational problems or incompatibilities with older installations.
⚠️ Caution: If you notice irregularities after the installation of a new meter (e.g., sudden increase in consumption or fluctuations), contact HEDNO immediately at 800 400 4000 (toll-free).
Common Reported Issues:
- Data transmission delays in certain areas
- Discrepancies between meter readings and billing
- Technical issues during installation in older buildings
- Need to replace incompatible electrical panels
❓ How the Installation Works
The meter replacement is carried out free of charge by HEDNO crews. The process includes:
- Notification: HEDNO notifies you in advance of the scheduled replacement
- Power outage: A brief outage is required (15-30 minutes)
- Installation: Removal of the old meter and installation of the new one
- Activation: Immediate power restoration and functionality testing
- Recording: Final reading of the old meter is taken
📱 The myHEDNO App
Alongside the smart meters, HEDNO has released the myHEDNO app for smartphones and tablets. Through it, consumers can:
- Monitor their consumption in real time
- Receive notifications about scheduled outages
- Report faults immediately
- Submit meter readings (for those who don't have a smart meter yet)
- Manage their supply details
⚡ Combating Electricity Theft
One of the most significant benefits of smart meters is combating electricity theft. According to data, illegal connections burden the energy market with more than €450 million annually, a cost that is ultimately passed on to legitimate consumers.
The new meters can detect suspicious activities such as:
- Tampering with the meter
- Consumption anomalies
- Illegal connections
ℹ️ What You Need to Know
🔒 Safety: Please note that HEDNO work is carried out exclusively in outdoor areas. Under no circumstances will HEDNO personnel request entry into your home. If someone asks you for this, it is an attempted fraud.
🎯 Conclusion
The transition to smart meters represents a significant modernization step for the Greek electricity distribution network. Despite the initial difficulties recorded, the long-term benefits for consumers and the energy system are undeniable. Real-time monitoring capability, accurate billing, and better network management will contribute to cost reduction and increased energy efficiency.
