The bus transport service covers almost the entire city and extends its operations outside city limits. In addition to buses, it also operates a ferry service. The electricity division of the organisation is also one of the few electricity departments in India to garner an annual net profit. Until 1995, BEST stood for Bombay Electricity Supply and Transport. After the name of the city was formally changed from Bombay to Mumbai, this was also reflected with the adjustment to Brihanmumbai, which means "Greater Mumbai".
