History and Development
National Grid was established in 1990 in the United Kingdom following the privatization of state-run electricity transmission assets.
Initially focused on consolidating and modernizing the UK transmission network, the company later expanded internationally, particularly into the U.S. market through strategic acquisitions in the Northeast.
Over time, natural gas distribution became an important part of its U.S. portfolio, further diversifying operations.
In recent years, National Grid has increased capital investment in grid modernization, renewable energy integration, offshore wind infrastructure, and decarbonization initiatives, aligning its strategy with long-term energy transition goals in both the UK and the United States.
