Generators were no longer limited by the power transmission of belts or the relatively slow speed of reciprocating engines, and could grow to enormous sizes.For example, Sebastian Ziani de Ferranti planned what would have been the largest reciprocating steam engine ever built for a proposed new central station, but scrapped the plans when turbines became available in the necessary size.A Babcock & Wilcox boiler powered a 125-horsepower steam engine that drove a 27-ton generator.This supplied electricity to premises in the area that could be reached through the culverts of the viaduct without digging up the road, which was the monopoly of the gas companies.In thermal power stations, mechanical power is produced by a heat engine that transforms thermal energy, often from combustion of a fuel, into rotational energy.Most thermal power stations produce steam, so they are sometimes called steam power stations.A power station, also referred to as a power plant or powerhouse and sometimes generating station or generating plant, is an industrial facility for the generation of electric power.Most power stations contain one or more generators, a rotating machine that converts mechanical power into electrical power.

Throughout the first few decades of the 20th century central stations became larger, using higher steam pressures to provide greater efficiency, and relying on interconnections of multiple generating stations to improve reliability and cost.High-voltage AC transmission allowed hydroelectric power to be conveniently moved from distant waterfalls to city markets.
