early warning system at Hydropower plant Sebzor
stationary measurement of Pamir Energy in the MOuntains of Tajikistan
Task
High in the spectacular Pamir Mountains of Tajikistan, Pamir Energy is building the Sebzor Hydropower Plant, a key project to deliver clean and reliable electricity to local communities.
Yet this breathtaking region faces an invisible danger of glacial outburst floods (GLOFs). When water trapped inside glaciers suddenly bursts out, it can unleash massive flash floods that race down narrow valleys, threatening lives, infrastructure, and progress.
Pamir Energy needed a fast, reliable, and autonomous early warning system to protect its workers and nearby residents.
Solution
To meet this challenge, Pamir Energy implemented a cutting-edge flood and flash flood early warning system,
combining advanced monitoring, smart communications, and automated alarms.
Two-Station Design
- Discharge Measurement Station – 7 km upstream
- Measures water level, velocity, and discharge with an
- RQ-30+ non-contact radar sensor
- Powered 100% by solar energy, ensuring continuous operation
- Sends real-time data via GSM to the MDS Cloud Server.
- Features a direct radio link to the siren station for instant communication, even when GSM is down
- Time lapse camera with picture transfer to MDS server
- Service switch to test system including radio and Alarm
Siren Station – Hydro Power Plant Sebzor Construction Site
- Receives live data from the upstream station every 30 seconds. Via Radio and GSM
- Activation can be triggered via radio or via GSM
- Automatically activates six 115 dB sirens (three facing upstream, three downstream) in under 30 seconds if flood thresholds are exceeded
- Siren placement was acoustically modelled to ensure maximum coverage in the valley.
- Allows customized MP3 sound and voice alerts for clear, localized evacuation instructions
- Stores all events in a data logger and reports automatically to the cloud
Implementation
The new system delivers powerful benefits for both safety and sustainability:
- 15-Minute Warning Time - Enough to safely evacuate workers and warn residents downstream.
- Full Autonomy - Solar power and battery operation guarantee uninterrupted function, even during disasters
- Dual Communication Paths - Redundant GSM and radio connections ensure reliability in remote conditions
- Community Protection - Sirens are loud, clear, and precisely engineered to reach all areas at risk
- Data-Driven Decision Making - Real-time monitoring enables proactive maintenance and risk management
