1831: Faraday demonstrates electromagnetic induction
Michael Faraday showed that changing magnetic conditions could induce an electric current. His experiments provided the operating principle for generators and transformers, allowing electricity to be produced from mechanical work rather than only from batteries.

Zénobe Gramme demonstrated a ring-armature generator in Paris. Its comparatively steady output helped make mechanical electricity generation useful for applications such as electroplating and lighting, moving electrical machinery toward industrial use.

Thomas Edison's Pearl Street Station began supplying electricity to customers in lower Manhattan. The system combined coal-fired generation, underground distribution, meters and incandescent lamps, providing an early model for a commercial electric utility.

Károly Zipernowsky, Ottó Bláthy and Miksa Déri patented closed-core transformers and developed a distribution system using parallel connections. Efficient voltage conversion made it practical to transmit alternating current at higher voltages and supply customers at lower ones.

Frank Julian Sprague's electric railway opened in Richmond, Virginia. Its successful operation on steep streets demonstrated a practical alternative to horse traction and encouraged other cities to build electric transit systems.

Galileo Ferraris and Nikola Tesla independently presented work on alternating-current motors using rotating magnetic fields. These designs helped make electric motors practical industrial power sources, eventually reducing factories' dependence on central shafts and belts.

An exhibition in Frankfurt received three-phase alternating-current power from a hydroelectric station at Lauffen, about 175 kilometers away. The demonstration showed that generation could be located far from the factories and cities consuming its output.

The Adams power station began generating electricity from Niagara Falls. Its alternating-current system supplied nearby industry and subsequently Buffalo, demonstrating how large hydroelectric plants could serve a wider regional economy.

The All-Russian Congress of Soviets approved a national electrification plan developed by engineers under Gleb Krzhizhanovsky. The program linked power-station construction with regional industrial development and made electricity infrastructure central to state economic planning.
https://en.wikipedia.org/wiki/GOELRO1933: Britain completes its national transmission grid
Britain completed a transmission network linking selected power stations through regional grids. Sharing generation reduced reliance on isolated local supplies and allowed more efficient stations to serve wider areas; nationwide synchronous operation followed later.

The Rural Electrification Act provided federal loans for power-distribution systems in underserved parts of the United States. Cooperative utilities used the financing to reach farms and communities that private suppliers had often considered uneconomic.
https://en.wikipedia.org/wiki/Rural_Electrification_Act1946: Ireland starts its rural electrification scheme
Ireland's Electricity Supply Board began a coordinated program to connect rural communities. Extending distribution lines over subsequent decades brought lighting, pumping and electrical appliances to households and farms beyond established urban networks.
https://en.wikipedia.org/wiki/ESB_Group1954: Gotland receives power through a direct-current cable
A high-voltage direct-current link connected the Swedish island of Gotland to the mainland. The commercial installation demonstrated a way to transmit electricity through long submarine cables and supported later links between distant or unsynchronized power systems.
https://en.wikipedia.org/wiki/HVDC_Gotland1965: Akosombo supplies Ghana with hydroelectric power
Ghana's Akosombo project began producing electricity from the Volta River. It supplied an aluminum smelter and the national network, while the reservoir displaced communities and altered the river system, illustrating the social costs of large power projects.
https://en.wikipedia.org/wiki/Akosombo_Dam1984: Itaipu begins generating for Brazil and Paraguay
The first generating unit at the jointly operated Itaipu Dam began running. The project developed into a major electricity source for Brazil and Paraguay, combining a large hydroelectric station with transmission systems serving two national markets.
https://en.wikipedia.org/wiki/Itaipu_Dam2003: Brazil launches Light for All
Brazil introduced Luz para Todos, or "Light for All," to extend electricity access in rural areas. Public financing, utilities and cooperatives supported connections for households left outside earlier grid expansion, making access a national development program.
https://en.wikipedia.org/wiki/Luz_para_Todos2012: M-Kopa launches solar power on installments
M-Kopa began commercial operations in Kenya, combining household solar equipment with mobile payments. Customers could pay in small installments, addressing the upfront cost of basic electricity services in places beyond reliable grid supply.
https://en.wikipedia.org/wiki/M-Kopa2013: India synchronizes its regional power grids
India connected its southern electricity grid synchronously with the rest of the country through the Raichur–Solapur transmission line. Operating the regional networks at one frequency strengthened the ability to move power across the national system.
https://en.wikipedia.org/wiki/National_Grid_(India)2015: China completes its electricity-access program
China announced that electricity access had reached its entire population after connecting remaining remote communities. Grid extensions and decentralized renewable systems addressed places where distance and difficult terrain had delayed conventional connections.
https://en.wikipedia.org/wiki/Rural_electrification2018: India connects its remaining unelectrified villages
India reported that all inhabited census villages had electricity infrastructure by April 28. The milestone covered village access rather than every household: the official definition required public facilities and a share of homes to be connected.
https://en.wikipedia.org/wiki/Rural_electrification2022: Bangladesh declares universal electricity coverage
Bangladesh's government announced universal electricity coverage in March after years of grid expansion and off-grid programs. The declaration concerned access; fuel shortages and a major blackout later in the year showed that dependable service remained a separate challenge.
