Bangladesh Gas Supply to Fall 13% During Summit LNG Maintenance on November 4–7

Summit shutdown will deepen an existing gas shortage

Bangladesh's gas supply is expected to fall by about 13 percent when Summit LNG Terminal in Maheshkhali, Cox's Bazar, suspends regasification for emergency maintenance from 8 a.m. on November 4 until 4 p.m. on November 7, 2026. Petrobangla warned that consumers across the country could experience low gas pressure during the work.

The shutdown will remove 320 million cubic feet of gas per day from the national grid. Supply from imported liquefied natural gas, known as LNG, will fall from 920 million cubic feet per day to 600 million, according to the state energy corporation's announcement on November 1.

Total gas supply is expected to decline from about 2,550 million cubic feet per day to 2,230 million. Bangladesh's daily demand is approximately 3,800 million cubic feet, meaning the country is already operating with substantially less gas than consumers need.

Industries and households in several areas are already experiencing low pressure. The temporary reduction will tighten that supply further, with potential consequences for factories, homes and power generation. Petrobangla apologised to consumers for the inconvenience.

When will the terminal stop supplying gas?

Petrobangla's schedule covers parts of four calendar days, from Wednesday morning to Saturday afternoon. The precise interval is 80 hours, or three days and eight hours. That timing explains why the maintenance period has been described as both three days and four days.

The announced sequence is:

• December 2025: Similar maintenance was carried out at Summit's terminal.
• November 1, 2026: Petrobangla announced the emergency maintenance and warned of possible low pressure.
• November 4, 8 a.m.: Regasification at Summit's terminal is scheduled to stop.
• November 7, 4 p.m.: The announced suspension is scheduled to end.

The notice identifies the work as emergency maintenance but does not describe the equipment involved or the specific problem requiring attention. Consumers have been given a national warning rather than a schedule identifying which neighbourhoods or industrial areas will face the greatest pressure reductions.

Why a terminal shutdown affects the national grid

Summit's facility handles imported LNG, which is natural gas cooled until it becomes liquid so that ships can transport it. Before that fuel can enter Bangladesh's gas pipelines, the terminal must turn it back into gas. This process is called regasification.

Maheshkhali has two floating storage and regasification units, often shortened to FSRUs. These facilities store LNG and convert it into gas for delivery to the national network. Summit Group operates one terminal, while the United States company Excelerate Energy operates the other.

Gas from these terminals joins gas produced at domestic fields. Both sources feed the network that serves consumers, so a reduction at one coastal facility can affect pressure far beyond Cox's Bazar.

During Summit's suspension, Petrobangla expects LNG deliveries to the grid to fall to 600 million cubic feet per day. That figure matches the stated daily capacity of Excelerate Energy's terminal. The maintenance therefore temporarily removes one of the country's two routes for converting imported LNG into pipeline gas.

Why the reduction is both 35 percent and 13 percent

The shutdown produces two different percentage reductions because imported LNG is only part of Bangladesh's gas supply. The loss of 320 million cubic feet per day represents about 35 percent of the current LNG contribution of 920 million.

Against the larger national supply figure of 2,550 million cubic feet per day, the same loss is approximately 12.5 percent, rounded to 13 percent. Domestic production continues to make up the rest of the national supply, limiting the percentage decline across the whole system.

The figures also show how the supply mix will change temporarily. Imported LNG currently accounts for about 36 percent of the stated national total, calculated from 920 million out of 2,550 million cubic feet per day. During maintenance, its share would fall to about 27 percent, calculated from 600 million out of 2,230 million.

For consumers, the practical issue is the smaller amount of gas entering the network. Pressure can weaken when available supply cannot keep pace with consumption, making it harder for equipment and appliances to operate normally.

Demand already exceeds supply by a wide margin

Bangladesh's estimated demand of 3,800 million cubic feet per day exceeds the main stated supply figure of 2,550 million by 1,250 million cubic feet. Before the maintenance, available gas therefore meets about 67 percent of estimated demand.

When supply falls to 2,230 million cubic feet per day, the gap will widen to 1,570 million. Available supply will then cover about 59 percent of demand. The maintenance adds 320 million cubic feet per day to an already substantial shortage.

Another set of figures attributed to Petrobangla puts current national supply at 2,520 million cubic feet per day, comprising 1,600 million from domestic fields and 920 million from LNG. Using that starting point, the same reduction would leave 2,200 million cubic feet per day. Both sets of figures describe a country entering the maintenance period with supply far below demand.

The existing shortfall matters because factories and households in several areas already face low pressure. The November interruption will arrive while those consumers are dealing with constrained service, rather than during a period when supply comfortably meets consumption.

What households, factories and power producers face

Petrobangla's warning applies to consumers across Bangladesh, although the effect will depend on local conditions in the gas network. A national reduction does not translate into an identical pressure drop at every connection.

Households could face weaker gas flows when using their appliances. Factories that rely on gas for heat or production processes could have greater difficulty maintaining normal operations if pressure falls further. Gas shortages can also affect power generation where plants depend on the fuel.

The concrete concern is that several types of consumers will draw from a smaller supply at the same time. Residential demand, industrial demand and fuel requirements for electricity generation all form part of the wider pressure on the network.

Petrobangla's announcement warns of low pressure rather than setting out a nationwide closure of consumer connections. It gives no sector allocation plan or district timetable for the maintenance period, so households and businesses have only the general warning and the terminal's scheduled suspension window.

Capacity and actual supply tell different stories

Summit's terminal is described as capable of supplying 500 million cubic feet per day, while Excelerate Energy's facility can supply 600 million. Together, those figures give a combined capacity of 1,100 million cubic feet per day. Another capacity figure attributed to Petrobangla puts the combined total at 1,050 million.

Current LNG supply is 920 million cubic feet per day under either account. Capacity means the amount facilities can potentially deliver; actual supply means the amount they are delivering at a given time. For the November maintenance, Petrobangla's operational forecast is a reduction of 320 million cubic feet per day.

The expected loss is therefore smaller than Summit's stated capacity of 500 million cubic feet per day. The maintenance calculation uses the announced change in deliveries, from 920 million to 600 million, rather than subtracting the terminal's maximum capacity from current supply.

Even the higher combined capacity figure illustrates the limits of the two terminals relative to national demand. Their stated maximum of 1,100 million cubic feet per day is equivalent to about 29 percent of the country's estimated requirement of 3,800 million. Domestic production remains a major part of the supply picture.

November 7 at 4 p.m. is the scheduled end of the regasification suspension. Petrobangla has also recalled similar work in December last year, placing this interruption within a recent pattern of maintenance affecting LNG deliveries. For consumers, the immediate development is a further temporary squeeze on an already limited gas supply.

• LNG supply to the national grid is expected to fall from 920 million to 600 million cubic feet per day, a reduction of about 35 percent.
• Total national gas supply is expected to fall by about 13 percent, from roughly 2,550 million to 2,230 million cubic feet per day.
• Daily demand is approximately 3,800 million cubic feet, leaving a larger shortage during maintenance.
• Petrobangla warned of possible low pressure across Bangladesh, where some industries and households already face weak supply.
