Additional information

The objective of the Noor-Ouarzazate Concentrated Solar Power Plant Project for Morocco is to increase (a) installed capacity (megawatts) and (b) electricity output (megawatt-hours), especially during peak hours, of the Noor-Ouarzazate Solar Complex. The project consists of two components. (1) Financing the initial investment component consists of (A) development of Noor-Ouarzazate II through the formation of a partnership between Moroccan Solar Energy Agency (MASEN) and a competitively-selected partner; (B) construction of the associated facilities needed for Noor-Ouarzazate II?s operation; (C) development of Noor-Ouarzazate III through the formation of a partnership between MASEN and a competitively-selected partner; and (D) construction of the associated facilities needed for Noor-Ouarzazate operation. Financing for construction of the associated facilities under sub-components (B) and (D) is covered by separate financing from donors to ONEE that has already been committed.
