The Osagyefo Barge is a 125 MW barge-mounted gas turbine electric power generating station located at Effasu in the Western Region of Ghana.

The 77 m long barge is equipped with a pair of single-cycle heavy-duty gas turbine units built by Ansaldo that have a combined generating capacity of 125 MW.

[2] The 125 MW power barge was ordered by the Ghanaian government in 1995 with financial assistance from the Overseas Economic Cooperation Fund of Japan.

The project development called for 450 MW of combined cycle power barges to belated in a man made lagoon.

[2][3] The offshore oil and gas fields did not develop as quickly as expected, so the power barge sat idle and its condition deteriorated.
