This is good lesson on the time necessary to evaluate, site, design and build power generation equipment. UAE wanted energy diversification so they started with nuclear and coal to offset their 100% supply of electricity from Natural Gas - mainly from Qatar which has seen a political tensions recently. Many years later, the perspective of coal is dramatically different. Their nuclear plant is behind schedule. Renewable energy in the form of utility scale PV is very competitive for day time peaks which are common in UAE due to HVAC demand.
Now they have a new coal plant that could supply 20% of their electricity, with coal from Indonesia or Australia. It will be interesting to see how this plant runs, and how the addition of renewables changes the landscape in the UAE.
