Malana Power Company Ltd, part of the LNJ Bhilwara Group, is a contracting and power consulting company with a reputation for delivering quality project management services for hydroelectric power projects. Malana is a major player in the Indian power sector and a leading independent hydropower engineer and producer.
LNJ Bhilwara Group was the first private sector company to set up a world-class hydro engineering and business consultancy services company, Indo Canadian Consultancy Services Ltd (ICCS), a joint venture with RSW International, the renowned Canadian consultants. The company set forth high standards of hydroelectric plant operation and maintenance on par with the world's best in the hydroelectric power sector.
HYDROELECTRIC POWER GENERATION PROJECT MANAGEMENT SERVICES
ICCS is a consultancy firm set up to carry out engineering activities related exclusively to cater to consultancy requirements for hydropower projects. It has a cumulative project exposure of 2500MW and a total of 100 consultants working for the firm. Furthermore, it is the only private sector company to have provided consultancy for the most number of completed hydroelectric projects in India.
86MW MALANA HYDROELECTRIC POWER PLANT
The 86MW Malana hydroelectric power project, at the time of construction, was one of the largest hydropower plant works projects in India. The hydropower plant is located on the Malana Nallah, a tributary of Parbati River in the Parbati basin, in the Kullu district of Himachal Pradesh.
Malana HEP is the first merchant power plant without a long term PPA, and is the first HEP with interstate wheeling and hydrology insurance cover. After obtaining all clearances from the Central Electricity Authority (CEA) and the Himachal Pradesh Government, construction of the 86MW project was started in 1999, and was commissioned in a record period of 30 months (compared to the schedule of 60 months) at a total cost of Rs350 Crores (US$76.46 million).
HYDROELECTRIC POWER PROJECT- BARRAGE/RESOVOIR AND POWER TUNNEL
The Malana hydroelectric power project involved the construction of a barrage/reservoir and head-works structures which included a 3.5km long power tunnel, a surface penstock with a diameter of 2.2m and a surface powerhouse complex.
The barrage diverts the river into four 102m long, 11.5m deep and 5.2m wide desilting tanks to remove silt particles down to a size of 0.2mm. The water is then led into the 2,500,000m³ capacity peaking storage (four hour) reservoir. From the reservoir, the water is conveyed through a 3.27km long, 3.4m diameter headrace tunnel and a 570m long, 2.2m diameter steel penstock to the surface powerhouse located on the right bank of the River Parbati. The water is released back into the river through a 500m long tailrace channel.
HYDROELECTRIC POWER - PELTON TURBINES
The powerhouse complex includes two vertical 43MW Pelton turbines, each with a designed discharge of 10.5m³, operating under an average net design head of 480m.
The hydroelectric plant is designed to generate 370 million units in a 90% dependable year and to provide peaking power for at least four hours a day during the lean seasons. The power generated by the hydroelectric plant is transmitted from the powerhouse up to the HPSEB sub-station at Bajoura/Sarabai through a dedicated 132kV transmission system.
The power generated at Malana is being wheeled through the Himachal Pradesh Electricity Board (HPSEB) system and the Power Grid Corporation of India Ltd (PGCIL) system to reach its short term customer for distribution, which is currently the Punjab State Electricity Board (PSEB).
