National Grid plc

National Grid plc (NGG) operates as a major energy utility, primarily overseeing the transmission and distribution of both electricity and natural gas. Its business is structured into several key divisions: UK Electricity Transmission, UK Electricity Distribution, the UK Electricity System Operator, and significant operations in the New England and New York regions of the United States. Within England and Wales, the UK Electricity Transmission segment manages the high-voltage power network and undertakes related construction projects. Concurrently, the UK Electricity Distribution division is responsible for delivering electricity to consumers throughout the Midlands, South West England, and South Wales. The UK Electricity System Operator plays a crucial role in maintaining equilibrium between electricity supply and demand across Great Britain's transmission system, and also acts as an agent for other transmission operators. In the United States, both the New England and New York segments handle the distribution of electricity and gas, as well as electricity transmission services, within their respective states. Beyond these core activities, National Grid also provides transmission services via international electricity interconnectors, manages liquefied natural gas (LNG) importation at the Isle of Grain, sells renewable energy ventures, engages in the leasing and sale of commercial property, and conducts insurance activities within the United Kingdom. Established in 1990, the company maintains its corporate headquarters in London, UK.
