Dubais flagship solar scheme has helped to drive down the cost of electricity generation through photovoltaic (PV) solar technology, twice holding the world-record lowest power purchase agreement tariff, for phases 2 and 3.
Phase 4 is a 200MW concentrated solar power (CSP) plant and Dubai Electricity & Water Authority expects to drive down the cost of that technology too. The firms CEO, Saeed Mohammed al-Tayer, has said he wants to achieve a tariff of about 8 cents a kilowatt hour ($c a kWh). If achieved it will be by far the lowest priced electricity generated by CSP in the world.
The 13MW first phase was commissioned in 2013. The 200MW second phase the largest operational solar PV plant in the Middle East was developed by Saudi Arabias Acwa Power with Spains TSK and the US First Solar. It was commissioned in March this year, with a tariff of 5.61 $c a kWh.
The 800MW phase 3 is split into three packages, which will be brought online in stages from April 2018. This phase is being developed by a Masdar-led consortium, with a tariff of 2.99 $c a kWh. The 200MW phase 4 is due to be commissioned in 2021.
