LAMP
In 1705 Francis Hauksbee (France) builds a gas discharge lamp using an evacuated glass tube charged with static electricity. The tube glowed faintly.
VOLTA
The voltaic pile, invented by Alessandro Volta in the 1800s was the first electrical battery.
In common usage, the word "battery" has come to include a single galvanic cell, but a battery properly consists of multiple cells.
FARADAY In 1831, using his "induction ring", Michael Faraday
made one of his greatest discoveries - electromagnetic induction: the "induction" or generation of electricity in a wire by means of the electromagnetic effect of a current in another wire. The induction ring was the first electric transformer.
In a second series of experiments in September he discovered magneto-electric induction: the production of a steady electric current. To do this, Faraday attached two wires through a sliding contact to a copper disc. By rotating the disc between the poles of a horseshoe magnet he obtained a continuous direct current. This was the first generator.
From his experiments came devices that led to the modern electric motor, generator and transformer.
BEGINNING OF COMMERCIAL UTILIZATION OF ELECTRICITY Beginning in 1836, the American artist
Samuel F. B. Morse, the American physicist Joseph Henry, and Alfred Vail developed an electrical telegraph system
Cooke and Wheatstone “invented" and patented the five needle electric telegraph for two way communications in 1837.
The first commercial electric telegraph entered use on 9 July 1839 on the Great western Railway in Britain.
It ran 21 km from Paddington station to West Drayton.
CARBON-ARC LAMP In about 1800 - Vasily Petrov (Russia) first
publicly describes the phenomena of the electric arc. The year of this is not yet confirmed.
The concept of carbon-arc lighting was first demonstrated by Sir Humphry Davy in the early 19th century (1802, 1805, 1807 and 1809 are all mentioned), using charcoal sticks and a 2000-cell battery to create an arc across a 4-inch (100 mm) gap. He mounted his electrodes horizontally and noted that, because of the strong convection flow of air, the arc formed the shape of an arch. He coined the term "arch lamp", which was contracted to "arc lamp" when the devices came into common usage.
In 1845 Mr Staite built an incandescent lamp using a fine rod of carbon enclosed in an evacuated glass bulb.
By 1857 generators were used to light up light houses.
The first reported case of domestic electric lighting was by Moses G. Farmer of Salem, Massachusetts, USA, who had lit a room in his house with incandescent lamps in 1858 for several months.
The first permanent installation of electric lighting was in 1873 in Gramme workshop at Paris, which produced electrical apparatus.
JOSEPH SWAN In 1850 Swan began working on a light bulb using
carbonized paper filaments in an evacuated glass bulb. By 1860 he was able to demonstrate a working device, and obtained a British patent covering a partial vacuum, carbon filament incandescent lamp. However, the lack of a good vacuum and an adequate electric source resulted in an inefficient bulb with a short lifetime.
Swan first demonstrated the light bulb at a lecture in Newcastle upon Tyne on 18 December 1878, but he did not receive a patent until 27 November 1880 (patent No. 4933) after improvement to the original lamp.
The world's first electric-light illumination in a public building was for a lecture Swan gave in 1880.
In 1881, the Savoy Theatre in the City of Westminster, London was lit by Swan incandescent light bulbs, the first theatre in the world to be lit entirely by electricity
THOMAS ALVA EDISON Building on the contributions of other
developers over the previous three quarters of a century, Edison made improvements to the idea of incandescent light, and entered the public consciousness as "the inventor" of the light bulb, and a prime mover in developing the necessary infrastructure for electric power.
After many experiments with platinum and other metal filaments, Edison returned to a carbon filament. The first successful test was on October 22, 1879; it lasted 13.5 hours. Edison continued to improve this design and by November 4, 1879, filed for U.S. patent 223,898 (granted on January 27, 1880) for an electric lamp using "a carbon filament or strip coiled and connected to platina contact wires"

The world’s first hydroelectric power station was installed by William Armstrong using water running through his estate to power various labour-saving devices in his palace at Cragside in Northumberland in 1870
In 1878 Sir William Armstrong used arc lamps to light his picture gallery at Cragside, Northumberland.
In 1880 he used Swan's incandescent light bulbs.
Cragside is the first house in the world to be lit by electricity generated from water power
FIRST HOUSE IN THE WORLD TO BE LIT
THERMAL POWER World’s first power plant driven by a
steam engine and using electric dynamos operating on Siemens principle was built in 1878 by Sigmund Schuckert to light the palace of King Ludwid II in the Baverian town of Ettal
RAILWAY ENGINE Dr. Werner von Siemens built and
exhibited the running of an electrically powered railway engine at the Berlin trade fair in 1879.
CENTRAL ELECTRICITY GENERATING STATION The first central electricity generating
station was built by California Electric Light Company owned by George Roe in September 1879 using a steam engine and two small dynamos.
ELECTRICITY IN INDIA THROUGH TELEGRAPHY Unlike other technological developments
in the West, electricity was introduced in India without a time lag in the form of galvanic electricity (both electro chemical and electromagnetic) through telegraphy, with the establishment of the first experimental line set up in Kolkata in 1839 at the Botanical Gardens along the river Hooghly
FIRST USE OF ELECTRIC LIGHTING IN INDIA First reported use of electric lighting was
in Mysore during the marriage of King Chamarajendra Wadiyar in May 1878 when twelve arc lamps with dynamo and gas engine imported from England illuminated his palace yard (Sharma, 2003).The Mysore palace electrification carried out by Mr. Charigton was the source of lighting up to 26th September1908, when power supply from Shivasamudram hydro electric plant reached the Mysore palace (Sharma, 2003).
ELECTRIC BULB IN INDIA On 20th July 1879, an Englishman, Mr.
Fleury (of P W Fleury & Co.) demonstrated an electric bulb to the people of Calcutta; A dynamo, driven by a small steam engine, generated electricity.
In Chennai a Frenchman Amedes Verne demonstrated a kind of generator that light up a few lights in people’s park in 1879
In 1881, thirty six electric lights lit up a Cotton Mill of Mackinnon & Mackenzie at Garden Reach, Kolkata.
Howrah Jute Mills Company also used electric lighting as early as the year 1881, which was discontinued after a few years to be restored again in 1895
ELECTRIC LIGHT Dey, Sheel and Co. of 36 Wellington Square
started a business of renting out dynamos in 1885 and was a pioneer of sorts in this field. They provided electrical lights for the dinner hosted on 20th December 1886 in honour of the delegates to the Calcutta Session of the Indian National Congress.
the King of Bikaner in Rajasthan started using a steam engine driven dynamo for his palace as early as 1886, bringing electrification to the subcontinent on a regular basis
STREET LIGHT In 1883 Mumbai Municipality entered
into an agreement with the Eastern Electric Light and Power Company to provide electric lighting in the Crawford Market and on some of the roads but the market got reverted to gas lighting as the company got liquidated next year
THE FIRST POWER PLANT
the Sidrabong Hydel power plant by Darjeeling Municipality was developed in the public sector under state patronage. Its work started in early 1895 and it was commissioned in the year 1897.
The first plant consisted of two 65 kW Crompton-Brunton single phase, 2300 volts, 83.8 cycles alternators coupled with two Gunther’s Turbines.
A total of one-lakh twenty thousand rupees were spent on setting up the Sidrabong Hydel Power Plant. No estimates of the money spent for construction of the transmission lines and other related expenses are, however, available.
Two more units of 135 kilowatts capacity each were added to the power station in 1905 and 1910 and two more of 200 kilowatts each in 1931 and 1935.
FIRST THERMAL POWER PLANT On 7th April, 1899 the first thermal power
plant of The Calcutta Electric Supply Corporation Limited was commissioned at Emambagh Lane, near Princep Street.
The plant in Emambaugh Lane consisted of three boilers of 500 horse-powers with eight dynamos and a storage battery... The chimney was the highest in Calcutta, being 40 ft. higher than the water works chimney which was close by.
In Calcutta the initial rate per unit of power was Rupee 1, the price being the same as in London.
ELECTRICAL EQUIPMENTS Among the Indian companies, Bengal Lamps
was established to manufacture electric lamps in 1932,
India Electric Works Ltd. started an integrated design ceiling fan factory in Calcutta around the same time.
Other important companies include Larsen & Toubro (a partnership of two enterprising young Danes) in 1938, Bajaj Electricals (1938), Ess Ess Kay Engg. (1935), Jyoti Ltd. (1943), Mysore Electricals (1945), Kirloskar Electric (1946) and GFM Manufacturers, Punjab (1946) etc.

INDEPENDENCE in 1947, the total installed capacity in
the country was 1392 MW (884 MW Thermal and 508 Hydro)
Private companies or local authorities supplied more than four-fifths of this total generation capacity.
After Independence it was necessary for the power sector to take the role of the development engine and the technological base for modern economic growth.
To give impetus for growth the vast majority of the private power entities were amalgamated into state owned enterprises and the government-owned SEBs were made responsible for all, new generation, transmission and distribution of electricity.
NUCLEAR The world's first nuclear power plant becomes
operational in Obninsk, outside of Moscow in 1954 June 27.
Tarapur Atomic Power Station was the first nuclear power plant in India. The construction of the plant was started in 1962 and the plant went operational in 1969 by Department of Atomic Energy.
The 320 MW Tarapur nuclear power station housed two 160 MW boiling water reactors (BWRs), the first in Asia.
The Tarapur Plant was originally constructed by the American companies Bechtel and GE, under a 1963 Agreement between India, the United States, and the IAEA.
NON-CONVENTIONAL ENERGY SOURCES Government of India created the
Department of Non-conventional Energy Sources (DNES) in September, 1982 under the Ministry of Science and Technology.
Now renamed as ministry of new and renewable energy
WIND ENERGY The first wind farm in India
consisting of 2x110 KW turbines of Micon make was commissioned on Mandvi sea beach, Kutch in Gujarat on 16th January 1986 using funding from DNES, by the Gujarat Energy Development Agency (GEDA) and the Gujarat Electricity Board (GEB).
Tamilnadu also started wind power generation almost at the same time – 10x55 KW machines of windmatic make at Tuticorin was commissioned on 18th January 1986
SOLAR POWER India's efforts to set up grid-connected solar power capacity
began as small demonstration projects. Punjab was host to the country's early demonstration projects.
In October 1999, two tiny projects, each of 50 kw (or 0.05 mw), were set up by the Union ministry of new and renewable energy.
The projects were established at Mini Secretariat Building and Village Bajak in Punjab, and are currently in operation.
In March 2003, a 0.2-mw grid-connected solar power plant (based on photovoltaic technology) was installed in Khatkar Kalan village of Punjab's Nawashahr district.
This plant was then India's biggest grid-connected solar power plant.
Constructed by Tata BP Solar, the plant was deployed to illuminate 100 street lights on the road leading to the Shaheed-e-Azam Bhagat Singh Museum.
ENTRY OF CENTRAL PUBLIC SECTOR
By 1970s it turned out that the SEBs’ internal accruals were insufficient for growth, and they sought assistance from the state in the form of grants, subsidies, soft loans, etc. This led to widespread blackouts by the 1970s and the system appeared headed for collapse.
The central government responded to the failings of SEBs by asserting greater control and created new state-owned corporations for power generation and transmission intended to supplement the SEBs.
