The project will be one of the world's largest solar field measured by peak thermal capacity.

[1] The plant uses large mirrors to focus sunlight and convert oilfield water into steam, which is then used to extract viscous or heavy oil from the ground.

[4][6] The 1 GWth project will reduce the amount of natural gas used to generate steam for thermal enhanced oil recovery (EOR).

Miraah will generate an average of 6,000 tons of solar steam each day, providing a substantial portion of the steam required at the Amal oilfield operated by Petroleum Development Oman (PDO).The enclosed trough solar field uses curved mirrors to focus sunlight – rather than using heat from burning natural gas – onto a pipe filled with water.

In November 2017, GlassPoint and Petroleum Development Oman (PDO) completed construction on the first block of the Miraah solar plant safely on schedule and on budget, and successfully delivered steam to the Amal West oilfield.
