Principal operations
Our principal operations are the ownership and operation of regulated electricity and gas infrastructure networks in the UK and the US, serving around 19 million consumers directly and many more indirectly. We also have interests in related markets, including electricity interconnectors, metering services, liquefied natural gas (LNG) facilities and property in the UK, LNG storage and transportation and non-regulated gas transmission pipelines in the US.
We have over 27,500 employees located in the UK and the US.
