The Dubai Future Experts Candidates asks:
Before 1 January 2021, will the Barakah nuclear power plant begin to supply electricity to the United Arab Emirates (UAE) power grid?
In an attempt to diversify its energy supply, the UAE has been constructing a nuclear power plant in cooperation with the Korea Electric Power Corp. (Bloomberg, World Nuclear Association). The first of four reactors has an operating license and is undergoing testing (Power Engineering, ME Construction News). Testing alone would not count.
NOTE 28 September 2020: For the purposes of this question, power ascension testing is considered testing and will not close the question.
