The Brihanmumbai Electricity Supply and Transport Undertaking (BEST) is a civic transport and electricity provider public body based in Mumbai, Maharashtra, India. It was originally set up in 1873 as a tramway company called "Bombay Tramway Company Limited". The company set up a captive thermal power station at the Wadi bunder in November 1905 to generate electricity for its trams and positioned it to also supply electricity to the city and re-branded itself to "Bombay Electric Supply & Tramways (BEST)" Company. In 1926, BEST also became an operator of motor buses. In 1947, the BEST became an undertaking of the Municipal Corporation and rebranded itself to "Bombay Electric Supply & Transport (BEST)". In 1995 the organisation was renamed to "Brihanmumbai Electric Supply & Transport (BEST)" alongside Mumbai. It now operates as an autonomous body under the Municipal Corporation. BEST operates one of India's largest fleets of buses. The bus transport service covers the entire city and also extends its operations outside city limits into neighbouring urban areas. In addition to buses, it also operates a ferry service in the northern reaches of the city. The electricity division of the organisation is also one of the few electricity departments in India to garner an annual gross profit. The idea of a mass public transport system for Bombay was first put forward in 1865 by an American company, which applied for a licence to operate a horse-drawn tramway system. Although a licence was granted, the project was never realized due to the prevailing economic depression in the city due to the end of the American Civil War, during which Bombay had made vast strides in its economy by supplying cotton and textiles to the world market. On 27 November 1871, a notice in the Times of India newspaper found to be too expensive and the tender was promptly abandoned. The "Bombay Tramway Company Limited" was formally set up in 1873.
