Larsen and Toubro (L&T), an EPC projects, manufacturing, defense and services conglomerate, has announced 100 percent completion and readiness for commissioning 99 MW Singoli-Bhatwari Hydroelectric Power Plant.
The commissioning of this run-of-the-river plant along the Char Dham route will provide a major boost to the state of Uttarakhand, with the plant's capability of providing over 400 million units of renewable energy per annum.
Located around 25 km from Rudraprayag, the plant features a barrage, with a medium-size intake pond near Ukhimath, a 12 km long headrace tunnel and a surge shaft over 180 mtr in-depth and is devoid of any rehabilitation and resettlement issues.
The plant houses three units of Voith Turbine generators of 33 MW each, equipped with a state-of-the-art switchyard and controlled via the latest Supervisory Control and Data Acquisition (SCADA) technology.
The SCADA systems are designed to automatically monitor and control the plant and its equipment such as telecommunications, water and waste control to take timely decisions and actions. This provides uninterrupted power supply at minimum generation cost.
Besides, the plant will cater to peak demand loads of 21/2 hours each in both halves of the day, bringing relief even during non-monsoon months and meeting peak electricity demand.
The wet commissioning process starts with machine spinning of the turbines initially without generation of electricity and upon due testing, eventual synchronisation with the grid for supply of electricity.
Grid synchronisation and charging of the transmission lines is expected in approximately a month, and is timed during inauguration of the plant.
The state's transmission utility PTCUL supported the project by executing one of the fastest-ever transmission lines connecting 75 km distance between the project site and the nearest sub-station.
