Ouarzazate Solar Power Station (OSPS), also called Noor Power Station is a solar power complex located in the Drâa-Tafilalet region in Morocco, 10 kilometres (6.2 mi) from Ouarzazate town, in Ghessat rural council area. At 510 MW, it is the world's largest concentrated solar power plant. With an additional 72 MW photovoltaic system, the plant produces 582 MW at peak, the process comprises three phases and in four parts. The total project costed $9 billion. 

The plant will be able to store solar energy in the form of heated molten salt, allowing for production of electricity into the night. Phase 1 comes with a full-load molten salt storage capacity of 3 hours. Noor II, commissioned in 2018, and Noor III, commissioned in January 2019, store energy for up to eight hours. It will cover an area of 2,500 hectares (6,178 acres).

The project is the first in a series of planned developments at the Ouarzazate Solar Complex by the Moroccan Agency for Solar Energy (MASEN). 

Water consumption for the Ouarzazate Noor complex is estimated at 2.5 to 3 million m3 per year for one wet- cooling project (Noor I) and two dry – cooling projects (Noor II and III), due to the need to clean the reflectors regularly.
