LS Cable & System said Monday that it has started to produce submarine cables at its facility in Donghae, Gangwon Province, using electricity generated from solar power in a strategic move to reduce electricity costs and enhance eco-friendly manufacturing capabilities.

The 3,000-kilowatt solar power system is expected to generate approximately 3,600 megawatt-hours of electricity annually, equivalent to the power consumption of about 1,200 households per year. Over the next 20 years, this could lead to saving over 7 billion won ($4.8 million) in electricity costs, according to the company.

LS Cable’s boost in green initiative comes as global energy companies increasingly require cable-makers to use renewable energy in their manufacturing processes. For instance, key companies like Orsted, Europe’s largest renewable energy firm, and TenneT, a German grid operator, actively pursue the decarbonization of their supply chains.

In addition, LS Cable is advancing its efforts toward environmental, social and governance efforts. In December 2024, it became the first cable-maker in South Korea to receive global approval for its carbon reduction strategy from the Science Based Targets initiative, or SBTi, by committing to achieve net-zero greenhouse gas emissions by 2050.

“Reaching 100 percent renewable energy transition at our Donghae facility through the solar power system is highly significant,” said an official from LS Cable & System. “We plan to extend the use of renewable energy across our domestic and international sites, building a low-carbon supply chain that aligns with RE100 and SBTi standards, as well as our customer requirements.”

Meanwhile, LS Cable, along with its sister company LS Electric, posted 1.3 trillion won worth of deals in the US early this year. Building on these achievements, LS Group plans to expand its production capacity within the US to further solidify its presence in the global cable and electrical equipment markets.
