Technology empowers Cambodian grids

PURSAT, Cambodia — In a country that once struggled with blackouts, Cambodian Power Grid Company, or CPG, now uses robots, drones, and AI to keep the lights on, while training local staff members to take the helm.

Starting operations in February 2013, the Chinese-invested CPG's 230-kilovolt transmission line delivers electricity from the 120-megawatt Stung Atay hydroelectric plant in Pursat Province, as well as other hydropower stations, to multiple regions across Cambodia, including Phnom Penh, Siem Reap, Pursat and Battambang.

Im Chhun, a power system operator of the CPG, said these projects ensure a reliable energy supply while facilitating the transfer of technical expertise from Chinese specialists to Cambodian staff.

According to Chhun, CPG has adopted advanced technologies to guarantee a stable power supply and employees have received comprehensive training to operate high-tech equipment.

"Currently, we can use robots to monitor equipment temperatures and operational status, and those robots will report directly to on-duty operators," he said. "We also use AI to assess damage and analyze weather forecasts, which are critical to power production."

Prak Tithyarith, a transmission line supervisor of the CPG, said his responsibilities include overseeing the 230 kV transmission line stretching 294 kilometers from Phnom Penh to Battambang.

Reducing workload

"Nowadays, advanced technologies have greatly reduced our workload," he said.

"In the past, workers had to patrol transmission lines manually during floods or in difficult terrain. Today, such patrols are no longer necessary, as drones are used instead," he added.

Tithyarith said that lasers are employed during maintenance to remove kites flown by residents that become entangled in power lines, as well as bird nests.

"There is no need for us to climb poles to remove them anymore," he said.

Tithyarith recalled that when he first joined the company, he knew very little, but his Chinese colleagues had taught him a lot about patrolling power transmission lines.

"I am deeply satisfied with this job because it allows me to directly serve the Cambodian people," he said.

Kong Phon, a substation operator, said the company provided six months of technical and Chinese language training before he began work.

"I truly enjoy working here," he said, adding that the company offers employees competitive wages, accommodation and meals.

Commenting on the working atmosphere, Phon said Cambodian and Chinese colleagues maintain close communication, forming relationships akin to those of family members.

"We get along very well, just like brothers or close friends," Phon said.
