National Grid plc is one of the world's largest investor-owned utility companies, playing a central role in the energy transition. The company's operations are divided into several key segments: UK Electricity Transmission, UK Electricity Distribution, and US regulated operations across New England and New York. While it historically operated the UK's gas transmission network, it has divested those assets to focus more heavily on electricity and clean energy infrastructure. In the US, it provides both electricity and natural gas supply and distribution services to millions of customers. Additionally, its National Grid Ventures division develops and operates large-scale clean energy projects, including electricity interconnectors and LNG importation facilities.
