Project Status : Supply & Construction

SUPPLIES

All ODC to be transported through Bangladesh dispatched from BHEL works. Transportation of ODC from Kolkata to Ashuganj in Bangladesh started in February’11 and last consignment expected to reach Bangladesh in May’11.

Supplies of non-ODCs to be transported via Gauhati started in Mar-10 and last dispatch from BHEL works for Unit-1 & Unit-2 is expected by Jun-11 and Sep-11 respectively.

CIVIL CONSTRUCTION

Piling and foundation of major buildings for Unit-1 completed and main plant equipment erection started in Jan-11.

Major structures for Unit-2 are likely to be ready for erection by Jun-11.

Work for Cooling Tower and Water Treatment System has commenced. CT-1 is likely to be commissioned in Sep-11 and Water Treatment System is likely to be commissioned in Jul-11

Construction of River Water Intake Pump house and pipeline has commenced and likely to be commissioned by Jul-11.

Routes: Kolkata – Ashuganj – Palatana Kolkata – Karimgunj - Palatana

Routes for transportation of ODCs from Kolkata: There are two routes available for transportation of ODCs to Palatana site:

Via Karimganj: 1318 KM (river) + 320 KM (road - India)

Via Ashuganj (Bangladesh): 856 KM (river) + 115 KM (road – India + B’dsh)

Ashuganj route has been selected because river route is navigable through out the year and road route passes through generally plain land leading to less risk in transportation.

Hon’ble Prime Minister of Bangladesh during her visit to India in Jan-10 agreed to allow movement of ODC through Ashuganj in Bangladesh. Since then, Ashuganj has been included in Indo-Bangla Water Transport Proto-call and MOU has been signed with GOB on 29th November 2010 formally allowing movement of ODCs through Bangladesh territory.

90 ODCs shall be transported through Bangladesh. Construction of bypasses in between Ashuganj (Bangladesh) and Palatana (Tripura) has breen completed.

13 ODCs have reached site, 2 are likely to reach site within 2-3 days and balance ODCs are expected to reach site progressively by Jun-11.
