When did the national grid begin?

The national grid in the United Kingdom began to take shape in the early 20th century, with the first major step occurring in 1926 when the Electricity Act was passed, leading to the establishment of a national network for electricity distribution. The grid was further developed and expanded over the following decades, culminating in the creation of the National Grid Company in 1990, which took over the management of the electricity transmission system in England and Wales.
