First waste-based power plant to be set up under IPP mode

UNB, Dhaka
After "not being able" to implement the country's first-ever waste-based power plant project at Keraniganj on its own initiative, the government has now decided to go for executing it on the IPP basis.
Official sources said the government revoked the move to implement the project on public initiative about 4-5 months back as it did not find any suitable bidder, and instead decided to execute it under the Independent Power Producer (IPP) mode.
"Overstating cost quoted by the bidders was the main reason behind the cancellation of the project on public initiative," said a top official of the power ministry.
Official sources said the power ministry had moved to implement the project on a pilot basis following interest
shown by State Minister for Power and Energy Nasrul Hamid, who is an elected member of parliament from the locality.
On many occasions, he mentioned that he wanted to implement the project as part of his plan to build his constituency as a modern locality.
When tender was floated by state-owned Power Development Board (PDB) last year to pick an engineering, procurement and construction (EPC) contractor for the project, four companies submitted their respective bids for the 1 MW grid-connected waste-based power plant.
In the evaluation, a Chinese company -Yamato Technologies Pte Ltd - was technically responsive. But when its financial offer was opened, it was found that the cost is much beyond the estimation.
A PDB official, who was involved in the tender process, said the Chinese firm offered about Tk 200 crore for such a (1 MW) project while the government's estimation was below Tk 100 crore.
He said when the firm's offer was sent to the power ministry, it cancelled the tender process finding such a huge cost and asked the PDB to move for implementing the project under private sector.
The official, preferring anonymity, also mentioned that after such a decision, the
same Chinese firm submitted an unsolicited offer asking for tariff of each unit of electricity at US 45 cents which is equivalent toTk37.
He said an evaluation committee of the PDB is now working on the offer of the firm.
Contacted, Nazmul Haque, head of the renewable energy cell of PDB, which invited the tender earlier, admitted the power ministry's latest directive for implementing the project as an IPP.
As per the concept, the private firm will set up the project at its own cost and the government will purchase electricity from it like other private power plants.
Officials said in such waste-based power plant, mostly organic waste, will be collected from residential and commercial areas, and also agro-industrial and medical garbage will be gathered from different areas to supply those to the plant for power generation.
Through anaerobic digestion process, the biogas will be produced and used for electricity generation. Some heat will also be generated in the process to generate electric power.
Officials said in the process, about 1 MW of electricity will be generated from the supply of 50 tonnes of garbage where composition is 430 kW Electricity + 480 kW Heat.
