Newfoundland Power Inc. is an electric utility owned by Fortis Inc. which is the primary retailer of electric power in the Canadian province of Newfoundland and Labrador.

In the year of its incorporation it purchased the assets of the St. John's Light and Power Company which had been formed originally by Robert Gillespie Reid as the St. John's Street Railway Company in 1896.

Those assets included Newfoundland and Labrador's first hydro electric generating station at Petty Harbour, Petty Harbour Hydro Electric Generating Station.

The Newfoundland Light & Power Company supplied the general needs of the St. John's urban area and operated the city's electrical street car system.

Newfoundland Power operates 23 hydro generating plants, three diesel plants and three gas turbine facilities for a total installed capacity of 139.4 MW.
