SEC and Hitachi Energy Partner to Eliminate Potent Greenhouse Gas from Power Grid

The Saudi Electricity Company (SEC) signed a memorandum of understanding with Hitachi Energy on February 8, 2025, in Riyadh to adopt advanced eco-friendly technology for electrical switches and circuit breakers free from sulfur hexafluoride (SF6), a potent greenhouse gas. The agreement, announced by the Saudi Press Agency, marks a significant step in the Kingdom’s efforts to decarbonize its electricity sector and aligns with its broader sustainability goals under Vision 2030. The MoU was signed at SEC headquarters in the presence of acting Executive Vice President for Technical Services Eng. Nasser Mohammed Al-Sulami and Hitachi Energy Managing Director in Saudi Arabia Mohammed Al-Masri.

Context and Background

Sulfur hexafluoride has been widely used in electrical equipment for decades due to its excellent insulating properties, but it has a global warming potential 23,500 times higher than CO2. The partnership between SEC and Hitachi Energy seeks to replace SF6 with environmentally friendly alternatives in high- and medium-voltage switches and circuit breakers, without compromising performance, quality, or safety. This initiative is part of Saudi Arabia’s broader commitment to reducing greenhouse gas emissions and transitioning to cleaner energy sources, as outlined in the Saudi Green Initiative and Vision 2030.

Key Details

The MoU covers the development and deployment of SF6-free technology across SEC’s grid infrastructure. Hitachi Energy, a global leader in sustainable energy solutions, will provide expertise and equipment using alternatives such as fluoronitrile-based gas mixtures that have a significantly lower environmental impact. The agreement builds on a long-standing relationship between the two entities, with Hitachi Energy having previously supplied transformers and other grid components to SEC. Financial terms were not disclosed, but the collaboration is expected to accelerate the adoption of green technologies in the Kingdom’s power sector.

Implications and Impact

This move positions Saudi Arabia as a regional leader in sustainable grid modernization. By eliminating SF6 from its electrical systems, SEC will reduce its carbon footprint and set a benchmark for utilities across the Middle East. The technology is also expected to enhance grid reliability and safety, as the alternative gases are non-toxic and non-flammable. Moreover, the partnership supports global efforts to phase down SF6 under the Kigali Amendment to the Montreal Protocol, reinforcing the Kingdom’s international environmental commitments. The collaboration could also stimulate local manufacturing and innovation in green energy technologies, creating new economic opportunities aligned with Vision 2030’s industrial diversification goals.

Vision 2030 Alignment

The SEC-Hitachi Energy partnership directly supports Vision 2030’s objectives of environmental sustainability and economic transformation. By deploying SF6-free technology, the Kingdom advances its goal of generating 50% of its energy from renewables by 2030 while ensuring a reliable and modern grid. This initiative complements other SEC projects, such as smart grid deployments and renewable energy integration, highlighting Saudi Arabia’s holistic approach to a greener future. As the Kingdom continues to host global events and attract international investment, such collaborations underscore its commitment to leading the region in sustainable development and achieving net-zero emissions by 2060.
