Bangladesh is set to build the country’s third 500MW back-to-back high-voltage direct-current (HVDC) sub-station in Comilla to import electricity from India.
“We have sent a report to the Power Division that a HVDC sub-station is required in Comilla, for importing an additional 340MW power from India,” a chief engineer of Power Development Board told the Dhaka Tribune on Thursday, on condition of anonymity.
India’s state-owned NTPC Vidyut Vyapar Nigam Ltd will supply 340MW power from several Bongaigaon power plants in Assam by December 2019, he added.
On December 11, 2016, Bangladesh’s proposal to import bulk electricity in addition to existing import of 660MW was received positively by India during the India-Bangladesh 12th joint steering committee (JSC) meeting in New Delhi.
Bangladesh proposed an additional import of 340MW in capacity from NTPC stations through a 500MW HVDC power sub-station in the northern part of Comilla.
An HVDC sub-station is a specialised sub-station which forms a terminal for high-voltage direct current transmission lines.
The project cost is estimated at Tk1,128 crore, of which Tk874 crore will be provided by the Asian Development Bank and the rest by the Government of Bangladesh.
Once finished, Bangladesh will import 500MW of electricity from India through the new power substation.
The first HVDC sub-station in Bangladesh is located in Bheramara, Kushtia. The state-owned Power Grid Company of Bangladesh Ltd (PGCB) is currently building the second such sub-station at the same site, to import electricity from India.
“It will be built by June 2018,” said a PGCB official.
Bangladesh is already importing 660MW of electricity from India: 500MW from Bahrampur through the existing HVDC substation in Bheramara, and another 160MW from Tripura via Comilla.
Dhaka is also negotiating a deal to import 1,600MW of power from Adani Group-sponsored power project at Jharkhand province of India, with a power tariff of Tk6.93 per unit ($0.086).
On April 16, 2017, State Minister for Power, Energy and Mineral Resources Nasrul Hamid said the government has undertaken an initiative to import an additional 2,000MW of electricity from neighbouring India within the next two years.
