A 170MW Integrated Solar Combined Cycle (ISCC) plant

The plant configuration includes the following elements:

• A solar field of aproximately 800,000 square meters with aluminium parabolic troughs,that will generate annually more than 1,000 GWh t.

• A high performance power block, with a robust HRSG, combining a steam turbine of 68 MW with a gas turbine of 114 MW which uses as fuel Natural Gas (NG).

• A molten salt thermal storage system capable of operating the steam turbine at full load for 12 hours after sunset
