National Grid Ventures develops, operates, and invests in clean energy infrastructure to accelerate society’s transition to carbon neutrality while at the same time helping to maintain security of supply. The company operates in the United Kingdom and the United States.
Challenge of the project
Strongly committed to decarbonizing the electrical installations under its responsibility, National Grid Ventures was seeking a sustainable and efficient solution to prevent the release of SF6 gas into the atmosphere, which can occur at high-voltage substations. MasterGrid, which offers the largest portfolio of SF6 gas management solutions, was consulted for its expertise and tailor-made products.
Our response
Thanks to our expertise in leak detection, sealing and SF6 gas capture, we were able to offer National Grid Ventures tailor-made containment systems adapted to each type of installation and location, while enabling them to ensure business continuity.
Systems adaptable to all GIS installations, regardless of brand
On-site intervention without operational disruption.
Electrical equipment that is more environmentally friendly and with optimized performance.
A comprehensive support, from feasibility study to installation.
I wanted to say a MASSIVE thank you for your repair works at Sellindge over the last couple months. Over the next 5 years, these repairs will have saved more than 5,000 tons of equivalent CO2 emissions leaking into the atmosphere.
