A standard national system would have been better, but the Conservative Government pf the time was against �socialist� nationalisation, so a compromise was reached. A �National Gridiron� of power lines was to be created, connecting up the most reliable power companies; in fact several regional �grids� were established, with emergency connections if needed. This �gridiron� was set up under the Electricity Supply Act of 1926, and the regional Grids were completed by September 1933.

14/6/1736, Charles Coulomb, electrical scientist, was born (died 23/8/1806).
31/7/1718, John Canton, English scientist (died 22/3/1772) was born. He developed a method of manufacturing artificial magnets.
3/10/1716, Giovanni Beccaria, Italian electrical physicist, was born in Mondovi (died in Turin 27/5/1781).
1600, The term �electricity� was used for the first time, by Gilbert, who also discovered that the Earth has a magnetic field. He named the phenomenon after the Greek word for amber, elektron.
600 BC, The Greek writer Thales of Miletus noted that amber from the shores of the Baltic (which the Greeks called elektron) when rubbed could attract small objects.
Appendix 3.5� � Electric Light (See also Light, Cameras, Optics)
9/5/1932. Piccadilly Circus first lit by electricity.
7/3/1910, Neon lighting was patented by Georges Claude. Neon was only discovered in 1898.Other gases can be added tio give different colours; a trace of argon makes blue light, and adding helium makes white or yellow light.
19/1/1883, The first electrical lighting system employing overhead wires began operating at Roselle, New Jersey, USA.
22/12/1882, The first string of Christmas lights was made by Edward H Johnson, a colleague of Thomas Edison.
4/9/1882, The Edison Electric Illuminating Company began producing electricity at Pearl Street, New York, USA. It had a total of 85 customers.
12/1/1882. The Edison Electric Light Company at 57 Holborn Viaduct established London�s first electric power station. It supplied the area between Holborn Circus and the Old Bailey with street lighting from 12/1 and with domestic current from 12/4/1882. In New York, USA, electric power was switched on from 4/9/1882. However the UK Parliament then passed the Electric Light Act; this discouraged private building of power stations because it empowered local authorities to take them over after 21 years. This made it impossible for private investors to recoup their money, in such a short time span, The Act was amended in 1888 to make the period of private operation 42 years. However even as late as 1890, major UK cities such as Manchester, Leeds, Nottingham and Edinburgh had no electric power.
20/1/1882, A drapers shop in Newcastle on Tyne, England, became the first shop to be lit by electric light.
4/9/1881. The Edison electric lighting system went into action in New York as a generator serving 85 paying customers was switched on.
27/1/1880. Edison patented the electric filament light (the electric light bulb).
1/10/1880, The Edison Lamp Works began operations in New Jersey to manufacture the first electric light bulbs.
20/12/1880, Charles F Brush demonstrated his arc lamps along Broadway, preceding Edison�s lamp in commercial use.
20/12/1879, Thomas Edison privately demonstrated his �incandescent light� at Menlo Park, New Jersey.
21/10/1879. Thomas Edison successfully demonstrated the first durable light bulb.
18/12/1878, Joseph Wilson Swan, 50, deomonstrated an electric light bulb in Newcastle on Tyne, England. However it did not achieve true incandescence
15/10/1878, The Edison Electric Light Company was founded.
1878, English physicist Joseph Swan ran electricity through a carbon filament encased in a glass bulb from which the air had been evacuated. His prototype incamdescent light lasted for several hours.
31/10/1828, Sir Joseph Swan, inventor of the electric light bulb independently of Edison, was born in Sunderland.
