At a time when the government has been emphasising austerity and efficiency in the energy sector, two repowering projects aiming to add 825 MW to the national grid at the state-owned Ghorashal Power Station have missed their scheduled deadline to start operating.  It is cheaper for the government to purchase electricity from state-owned plants than private ones with their higher tariffs. Repowering is the process of replacing older power stations, or units at power stations, with newer ones that either have greater capacity or more efficiency, resulting in a net increase of power generated.  According to a government document, seen by UNB, the two projects are the repowering of 416 MW Unit-3 and the 409 MW repowering of Unit -4 at the Ghorashal Power Station (GPS).

The government selected two separate EPC (engineering, procurement and construction) contractors for the two projects, which were awarded the jobs on turnkey basis. Of these a consortium of GE (Switzerland) GmbH and CMC, China was selected for unit-3 of the Ghorashal Power Station while China Energy Engineering Group, Guangdong Power Engineering Co. Ltd. (CEEC) was awarded unit-4. Unit 3: At least 9 months more The state-owned Bangladesh Power Development Board (BPDB) signed the EPC contract with Consortium of GE (Switzerland) GmbH and CMC, China in February 2016 to implement the 416 MW unit-3 combined cycle power project. The agreement was effective on January 22 in 2017 setting a deadline for the simple cycle’s commercial operation date (COD) in January 2019 while  the combined cycle’s COD was set for September 2022. The contractor failed to complete its job as per the schedule. The document says the issue of the project was discussed in a review meeting at the Power Division on 14 November, where it was informed that the project will need at least 9 months more time to start its commercial operation as the “hot “commissioning of turbines is not possible before that. “Due to problems with the blades on the compressor side of the gas turbine, it now remains shut. The tender document was sent to the contractor for the work,” it was mentioned as the review meeting’s resolution.

As per the agreement, the COD of the simple cycle of the project was set for April 2018 while the combined cycle’s COD for October 2019. Although after a six month-delay the simple cycle came into operation in October 2018, the combined cycle has failed to come into commercial operation till now. The issue was also discussed in the review meeting of the Power Division where it was informed by the BPDB that the commissioning of the Steam Turbine of the project was not possible because of different problems including “high rotor eccentricity and high shaft vibration”. As per the meeting’s resolution, it is mentioned that the contractor was asked to submit a new proposal by contracting with the original equipment manufacturer, said to be Russian. The work needs further approval of the Cabinet Committee on Government Procurement (CCGP) as the existing contract has no scope to allow additional cost for the steam turbine’s required repairs. Despite repeated attempts, BPDB’s additional chief engineer Abdul Basit, who was the project director, could not be reached on his mobile phone to comment on this story.    Read more: 3-hr cuts in Desco areas after Ghorashal 365MW plant breaks down The Power Division official said the cost of power generation through government plants is much lower than that of private plants. “But as such public sector plants are not coming into operation as per schedule, the government will be deprived of cheaper electricity while it’s struggling with buying electricity at a higher rate from the private sector,” said an official who wanted not to be named.   

After two weeks of remaining out of order, the 210 MW capacity unit-5 of Ghorashal Power Station has resumed operation. “Unit-5 of Ghorashal Power Station is in operation since yesterday and is now generating 170 MW electricity, against its installed capacity of 210 MW,” Shamim Hasan, public relations director of Bangladesh Power Development Board (BPDB), told UNB. Ghorashal Power Station’s unit-5 went off along with other units following the National Power Grid failure on October 4, 2022.

As a result, Dhaka city and adjoining areas were getting relatively less power supply from Ghorashal. The power station plays a major role in electricity supplied to Dhaka. Due to a major technical fault, officials failed to resume power generation from unit-5 of Ghorashal. After repair, BPDB engineers managed to resume the unit’s operation at the plant yesterday (October 19, 2022).

Dhaka city and adjoining areas are still experiencing frequent load shedding due to a huge gap between power supply and demand. BPDB data shows the country’s power generation varies between 11,000 MW and 12,000 MW, following the national power grid failure on October 4, 2022 – against a demand for about 14,000 MW.

Since the national power grid failure on October 4, 2022, Ghorashal Power Station could not resume operation in full capacity, a top official of Bangladesh Power Development Board (BPDB), has said. “Ghorashal Power Station may take one more week to resume electricity generation in full capacity,” he said, wishing not to be named.
