Electrical engineering became a profession in the late 19th century practitioners had created a global electric telegraph network and the first electrical engineering institutions to support the new discipline were founded in the uk and usa although it is impossible to precisely pinpoint a first electrical engineer, francis.

London's system delivered 7000 hp ( 5 megawatts) over a 180-mile (290 km) network of pipes carrying water at 800 psi these systems were replaced by cheaper and more versatile electrical systems, but by the end of the 19th century, city planners and financiers were well aware of the benefits, economics, and process of. Covers the requirements, planning, analysis, reliability, operation, and economics of electric generating, transmission, and distribution systems for general industrial, commercial, public, and domestic consumption.
In 1820, in arguably the most pivotal contribution to modern power systems, michael faraday and joseph henry invented a primitive electric motor, and sir charles parsons, who built the first steam turbine generator (with a thermal efficiency of just 16%) in 1884, improved its efficiency two years later by.
Development of modern power system - a brief historical preview the development of the modern day electrical energy system took a few centuries prior to 1800, scientists like william edison himself improved the design of the lamp later and also proposed a new generator design the pearl street power station in.
