Abengoa has selected Siemens Energy to provide long-term maintenance services for the gas turbines used in its 150MW solar hybrid power plant in Algeria.
As per the contract, Siemens will undertake preventative and corrective maintenance for two SGT-800 gas turbines which it installed last year, and ensure long term reliability of the gas turbines and expected maintenance costs for Abengoa.
The hybrid power plant uses Integrated Solar Combined Cycle (ISCC) technology which involves a combination of solar energy and conventional combined cycle plant to generate electricity.
Siemens Energy Service, Middle East region head Karim Amin said, "As these unique and advanced hybrid plant technologies continue to emerge, maintaining their efficiency with cost-effective service solutions is vital."
The project operating at the Hassi R’Mel natural gas field in northern Algeria is the country’s first solar-combined cycle hybrid power plant with 224 parabolic trough collectors covering an area of 180,000 square meters.

By GlobalDataHassi R’Mel hybrid plant generates power using two 25MW parabolic trough solar collectors field and a 130MW 2×1 Combined Cycle Power Plant.
The steam cycle and gas turbines used in the plant are fired by natural gas and the steam cycle is further fired by the additional steam generated by the solar energy during the day.
The environmental benefits and the operational advantage of solar energy and combined cycle plant together decrease emissions and increase the efficiency of the plant, said Siemens.
