CLP Power has commissioned three substations in the Northern Metropolis, a move the company says will be sufficient to meet the region’s electricity demand for the next decade.

The power giant underscored the strategic importance of the Northern Metropolis as a key growth engine for Hong Kong, pointing to major developments such as the Hong Kong-Shenzhen Innovation and Technology Park, the MTR’s Northern Link and future supercomputing and data centres — all of which will require stable and substantial power supply.

Of the three substations, which were all put into operation in 2024, one is situated adjacent to the talent accommodation of the Hong Kong-Shenzhen Innovation and Technology Park, primarily serving the park and the Lok Ma Chau Loop.

Another is located in Kwu Tung North, supplying electricity to that area as well as the new development zone at Ma Tso Lung.

A third facility, on Ma Sik Road, powers the Fanling North New Development Area.

According to CLP, the combined capacity of these substations is equivalent to the electricity demand of four to five Hong Kong Science Parks, ensuring ample supply for the three districts in the years ahead.

Michael Lau, CLP Power’s north region power systems director, said the company works closely with both the government and private stakeholders to align with development plans.

“We maintain close communication with the government’s development blueprint and stakeholders, including data centre operators, to understand their electricity consumption and quality requirements," he said.

"Based on these factors, we tailor short, medium and long-term power supply solutions for data centres to help them commence operations as soon as possible."

Unlike previous infrastructure in the New Territories that relied on overhead transmission towers, the three new substations use underground cabling.

Lau noted this design enhances resilience against severe weather and improves overall supply stability.

“Underground cables are less susceptible to external influences, such as severe weather, allowing us to maintain high supply reliability," he said.

"We have also put a lot of thought into the grid design, such as incorporating different backup power sources at supply points, ensuring that power is not affected even in the event of an incident.”
