First unit begins operating at 60-MW Tuirial hydroelectric in Mizoram, India

The first of two units at the 60-MW Tuirial hydroelectric project in the Kolasib district of Mizoram, India, has been commissioned, according to Bharat Heavy Electricals Limited.

BHEL’s scope of involvement in the development of this project involves the design, manufacture, supply, installation and commissioning of the complete electrical and mechanical package. This includes vertical-shaft Francis turbines and generators, each unit with a capacity of 30 MW.

This greenfield project, on the Tuirial River, is owned by the North Eastern Electric Power Corporation Limited (NEEPCO) and is the first large hydropower project in the state of Mizoram, BHEL says.

Power production from Tuirial will reduce greenhouse gas emissions and contribute toward achieving a low-carbon development path for India, BHEL says. NEEPCO says annual generation from the project is estimated to be 250.63 million units in a 90% dependable year.

This project has a long history. The Cabinet Committee on Economic Affairs (CCEA) clearance was obtained in July 1998. Once the five different packages were awarded, work began progressing in 2001. Project work stopped in 2004 when the Tuirial Crop Compensation Claimant Association requested crop compensation. In March 2010, the Press Information Bureau recommended reviving the project, and CCEA clearance was obtained in January 2011.

According to NEEPCO’s website, “The Project is proposed to be funded by Equity from Govt. of India, Loan from domestic Financial institution, Sub-ordinate loan to be granted by the Govt. of India and grant from DoNER [Ministry of Development of North Eastern Region] with debt equity ratio of 85:15.” Total cost to develop Tuirial has not been disclosed.

NEEPCO was incorporated in 1976 to plan, investigate, design, construct, generate, operate and maintain power stations in the North Eastern Region of India. NEEPCO operates five hydro, three thermal and one solar stations with a combined capacity of 1,251 MW (not including Tuirial). The company has four other projects under development: 110-MW Pare hydro, 600-MW Kameng hydro, 36 MW Tripura steam and a 2-MW solar project.

BHEL also is currently executing work for NEEPCO’s Kameng hydropower facility in Arunachal Pradesh. BHEL says it is presently executing about 6,000 MW of hydro projects, about half of which are outside India.

Earlier this month, HydroWorld reported on other new development work ongoing in India, with the award of a contract to develop the 93-MW New Ganderbal hydro plant.
