KUCHING: Sarawak Energy Bhd (SEB) is expected to build a 40km-long power transmission line to link Miri in northern Sarawak and Brunei in two years to facilitate the export of electricity to the oil sultanate.
Sarawak Public Utilities Minister Datuk Amar Awang Tengah Ali Hasan said the project would take 18 months to complete.
“Brunei has the potential to import 100 MW from Sarawak in 2012, an additional 50 MW in 2013 and a further 50 MW in future years,’’ he said.
Awang Tengah said this before handing over a copy of the Final report for the feasibility study on the Sarawak-Brunei power interconnection system to Brunei Energy Minister Datuk Seri Pahlawan Mohammad Daud here yesterday.
He said the price of the electricity to be sold to Brunei would be determined later.
The feasibility study on the power-generation capacity expansion for Brunei was commissioned after the signing of a memorandum of understanding between the Department of Electrical Services Brunei and SEB in May last year.
Brunei is now relying 100% on gas generation for its 66kV main grid system. It has the option to buy competitive electricity from Sarawak’s 275kV grid from specific hydroelectric projects.
According to SEB, which generates and distributes electricity in Sarawak, the first phase of the power export to Brunei would be via Tudan in Miri and connect to Brunei via the border point at Sungai Tujuh.
Connection will be via a 275kV transmission line of about 13km between Tudan and Sungai Tujuh.
As actual power demand in Brunei is in Kuala Belait and Spark areas, the transmission interconnection has to extend beyond Sungai Tujuh to Kuala Belait (which is about 18km), where a 275kV/66kV sub-station has to be built.
Eventually, Brunei intends to develop a 275kV transmission backbone spanning Sungai Tujuh-Kuala Belait-Spark-Bukit Panggal-Katok.
The proposed second phase of power export to Brunei will be via Limbang, probably in conjunction with the development of the proposed 200 MW Limbang hydroelectric project (II), which is expected to be completed by 2015.
The proposed dam site is 151km from the Limbang river mouth. The power from the dam will be supplied to Brunei via Limau Manis.
There is another plan to go westward through Brunei’s Temburong district to connect with Lawas town in Sarawak, and also supplying Bangar in Temburong.
Awang Tengah said with the development of the proposed hydroelectric projects in the northern region, Sarawak planned to develop an integrated Brunei-Sabah-Sarawak regional grid linking Limbang and Lawas (Sarawak), Brunei and Sabah.
