MIRI: Sarawak Energy is making good progress on its reinforcement works, costing almost RM1bil, to enhance reliability of supply and system stability here.

A number of major projects implemented since 2014 include additional injection points with the construction of a number of zone substations in urban Miri and its outskirts to cater for the city’s rapid development and expansion, as well as the upgrading of other infrastructure such as additional feeders, transformers, replacement of ageing equipment and power lines.

“It is critical to strengthen supply to Miri given the rapid development, expansion and the increasing population density,” said Sarawak Energy group chief executive officer Sharbini Suhaili.

“We will be able to achieve this through our reinforcement initiatives and a dedicated technical team in Miri.

“Most of the projects and upgrading works are expected to be completed within the next five years. Upon completion, we expect to strengthen the Miri network significantly,” he said.

Assistant Land and Air Transportation and Safety Minister Datuk Lee Kim Shin conducted a site visit to the Tudan 275kV substation.

He expressed his appreciation to Sarawak Energy and its team for their hard work and dedication.

“I would also like to thank Sarawak Energy as a whole for providing funding for Miri’s electricity supply.

“With the Tudan station now up and running, we are no longer receiving complaints about power disruption.

“This means that residents in this area are enjoying a reliable and stable power supply,” said Lee.

Sarawak Energy northern regional manager Tan Joo Kok accompanied Lee on the site visit.

Lee was briefed on the project’s progress and the overall system reinforcement projects for the city.

The reconstruction of Tudan substation, which serves as a major injection point for Miri, along with cable laying works provided additional capacity and backup for the city’s supply.

Prior to its reconstruction, the substation was heavily loaded which made it susceptible to tripping, causing major outages in the city.

Reinforcing the southern part of Miri was also a key focus area because of the current line performance. Marudi Junction Transmission substation, which is expected to come online by early 2018, will cater to the growing load demand in this part of Miri.

Tan said the operations team has doubled the initiatives to minimise the risk of unplanned interruptions by increasing line patrols and stepping up maintenance and vegetation management at overhead lines.

Nevertheless, he also said other causes of the outages in Miri include excavation works damaging underground cables, copper theft and vandalism to power facilities.
