Details of journey

 NHCE organized an industrial visit on 18 April 2023 to Varahi underground power house to students AI & ML Dept of. The visit was organized by the HOD of AIML Dept Dr. Uma Reddy, Industrial Visit Coordinator Prof Sonia Maria Dsouza along with Prof. Shruthi S. & Dr Sreejith S  were the Faculty Coordinators for the entire visit. We started traveling from the college campus at 9:30 pm the previous night in a private bus. Totally 89 students along with 3 faculty coordinators were there on the journey.

Day 1:

We reached Horanadu at 7.00 am in the morning. Students were given a few minutes to get refreshed. Later there was a jeep ride arranged by stay overseas where they took us on the roads and familiarized us with the western ghats ranges, later at 10am.We returned to the stay freshened up and left for Varahi for the industrial visit .We reached Varahi’s underground power house and spent enough time understanding the new technology and fascinating machines which powered

the entire system. After the visit, we came back to the stay and got introduced to the South Indian customs and traditions in Horanadu.

Day 2:

We left Horanadu at around 10.30 am in the morning to Mangalore. On our way we visited St. Lawrence Shrine Basilica , a Roman Catholic church in Karkala, India. It was built in 1759 and is purported to be the site of many miracles. It is characterized by its Attur Jatre or Attur Festival.

Attur Church is situated on the outskirts of Karkala in the Karnataka state of India. It is situated 58 km from Mangalore.

Placed amidst placid greenery, the Attur-Karkala parish has a rich history. The church oversees a school and an orphanage

We reached Mangalore at around 6 pm in the evening and stayed there for the night.

Day 3:

The next day morning at 11.00 am we started traveling back to Bangalore and we reached college at 9:00pm.

Company Profile:

Varahi is a 460MW hydropower project. It is located on the Varahi river/basin in Karnataka, India. which is near Hosangadi in the Udupi district of Karnataka The project is currently active. It has been developed in multiple phases. Post-completion of construction, the project got commissioned in 1989. The project generated 1,100 GWh of electricity.

An underground power station is a type of hydroelectric power station constructed by excavating the major components (e.g. machine hall, penstocks, and tailrace) from rock, rather than the more common surface-based construction methods. The power plant consists of 4 x 115 MW Generating Units at Varahi Underground Powerhouse. There are four turbines in operation and the capacity per turbine is 115 MW. The type of Turbine used is Pelton and the turbine and Generator of the hydroelectric project is manufactured by Bharat Heavy Electricals Limited of India. There are four units in operation.

Andritz Hydro was selected to render EPC services for the Varahi (Varahi II).

Bharat Heavy Electricals was selected as the turbine supplier for the hydropower project. The project consists of 4 units of Pelton turbines, each with a 115MW nameplate capacity.

Bharat Heavy Electricals was selected as the generator supplier for the hydropower project. The project consists of 4 generators.

Group Observation

Industrial visits enhance the practical knowledge of students to empower them with the recent developments in the core field and also to provide them with a fair idea of the work environment at the power station.

  • Got practical knowledge about the advancement in technology of machines.
  • Use of programming in the field of Mechanical
  • Management of manpower and
  • How underground power plants can produce electricity 24/7
  • Discussed possible future enhancement in the field

Thank you note

As described by students who participated in the industrial visit, the visit was a great opportunity for the Artificial Intelligence & Machine Learning Engineering (AIML) students to gain practical knowledge about advanced technology used in the generation of high voltage current using hydroelectric power. Students are very happy to express their gratitude to Management, the Principal, HOD & faculty members for their tremendous support and encouragement. We also thank the authority of Karnataka Power Corporation Limited (KPCL) and Staff members for their great support to visit the powerhouse.
