About 10 billion dollars would be required in the short to medium term to meet the investment requirements for power generation and transmission infrastructure under the West Africa Power Pool Project (WAPP), Energy Minister Mike Oquaye has announced. The amount would be used to rehabilitate and construct new generation plants and to upgrade and build new transmission lines over the next 10 years, including the establishment of interconnection infrastructure and development of hydropower plants such as Keleta in Guinea and Felou in Mali. The World Bank has already committed a 350-million dollar line of credit for the development of the WAPP out of which the Ghana Government and the Volta River Authority had secured 40 million dollars to implement the 330KV Aboadze-Volta Transmission Line.
