Senegal: MCC Transmission Network Upgrade Activity

Project number: SE2-2750BXCOMD-TRANS NTWK-0367 Funding account: Millennium Challenge Corporation, Expenses Channel: U.S. Government - Millennium Challenge Corporation Senegal Power Compact - Transmission Network Project - Transmission Network Upgrade Activity: This Activity aims to ensure the security and reliability of electricity supply to the Dakar peninsula, while guaranteeing long-term demand, through the construction of a 225 kilovolt ("kV") transmission loop and related infrastructure. MCC and the Government identified and agreed on specific components under this Activity through an assessment of the optimum transmission network configuration and development of an investment plan. This Activity is anticipated to include final design and construction of the following: with related conduits and manholes; (B) an underground, 225 kV, double circuit between Kounoune - Cap des Biches of approximately 7 km in length, an extension of the existing 225 kV gas-insulated substation at Kounoune, as well as installation of two new 150 megavolt amperes ("MVA"), 225/90 kV transformers, and a gas-insulated substation, including busbars and four feeders, at Cap des Biches substation; and (C) a 16 km, 225 kV, undersea cable, between Cap des Biches and Rive Bel Air, and a 225 kV underground, double circuit of approximately 2 km in length from Rive Bel Air to Centrale Bel Air. The substation improvements shall include two new 150 MVA 225/90 kV transformers, new gas-insulated substations, 225 kV feeders and switches, grounding equipment, and control equipment, as well as an extension of the existing 90 kV gas-insulated substation at Centrale Bel Air. Final network configuration for this Activity shall be determined and validated during final design.
