Unit 1 of the Barakah plantin the Al Dhafrah region of Abu Dhabi started producing heat on Saturday, the Emirates Nuclear Energy Corporation said in a statement. Unit 1 is the first of the plant's four nuclear reactors to launch. The corporation said the construction of Unit 2 has finished recently, while the other two reactors are still being built — even though the original schedule called for the plant to become operational by 2017.Once completed, the four reactors, which are using South Korean technology, should produce 5.6 gigawatts of electricity and supply up to 25% of the UAE's electricity needs, the corporation said. Mohamed Ibrahim Al Hammadi, the corporation's chief executive, said the reactor's launch was "a truly historic moment for the UAE.""We are now another step closer to achieving our goal of supplying up to a quarter of our Nation's electricity needs and powering its future growth with safe, reliable, and emissions-free electricity," he said in a statement. The new plant is part of the UAE's plan to become less reliant on oil and gas, the current source of the vast majority of its energy. UAE is among the world's biggest fossil fuels producers. It has seen a rapid economic growth in recent decades thanks to its oil and gas production, which makes up almost a third of its GDP. It has exported $50 billion worth of crude oil in 2019 alone. But the fast growth of the economy has also meant a huge increase in the country's energy demand and the need for alternative sources.The International Atomic Energy Agency, which oversees the use of nuclear energy around the world, hailed the plant's launch as "an important milestone." However, some experts have questioned the need for the nuclear power plant given the country's potential to develop solar energy and the tensions surrounding nuclear power in the Middle East.
