The Indian developer is seeking tenders for work on the 40MW Dhaulasidh project to its reset submission deadline of 30 April.

Dhaulasidh is to be built on the river Beas in Himachal Pradesh in northern India. It is to have a 130m high concrete masonry dam with discharge capacity of 13,335m3/sec.

While plans have been developed to have the project built with a capacity of 40MW, earlier this year the state Government said the plant could be up to 60MW.

The previous deadline for consultants’ offers was in February.

SJVN, which is a joint venture between the state and the Government of India, is also calling for consultants’ bids for studies and design work on the Arun III project to be built in Nepal.

The deadline for the Request for Proposals (RFP) was reset from January to 7 May. Prequalification of consultants was undertaken in the second half of 2008.

SJVN was awarded a concession a year ago to develop the 402MW project on the river Arun on a build, own, operate and transfer (BOOT) basis. The successful consultant will prepare the feasibility, design and bid materials, and undertake the necessary investigations, such as environmental impact assessment and geological studies. Work is to be completed within 16 months.

The planned main features of the project include: a 68m high by 155m long concrete gravity dam with an integrated spillway to discharge a Probable Maximum Flood (PMF) of 8100m3/sec through three radial gates; four underground desanding basins; a 97m high surge shaft; a 11km long headrace tunnel of 7.5m width.

The project is also to have a 161m long by 22m wide by 35m high powerhouse cavern. The transformer and switchgear cavern is to be 210m long by 10m wide by 10m high.

The plant, which has a design discharge for generation of 160m3/sec, is to have six Pelton turbines each of 67MW capacity. The maximum gross head is almost 304m and the plant is expected to generate approximately 2890GWh of electricity per year.

SJVN aims to develop a hydro portfolio of up to 4GW in the next few years although Himachal Pradesh believes the JV company could potentially have an asset base of up to 6GW.

Formerly known as Nathpa Jhakri Power Corp (NJPC), the JV company owns and operates the 1500MW (6 x 250MW) plant of the same name.

Other projects under development in India include Rampur (412MW), Devasari (252MW), Naitwar Mori (59MW) and Jakhol Sankri (45MW).

The company has also been allocated to develop the Khab (1020MW) and Luhri (775MW) projects.

In Bhutan, SJVN is preparing the detailed project reports for the Wangchu (900MW) and Kholongchu (486MW) projects.
