Barakah Nuclear Plant Unit 2 connects to UAE’s transmission grid

After the safe and successful start-up of Unit 2 on 27thg August 2021, the Barakah Plant became the first multi-unit operating nuclear plant in the UAE and Arab World. This reflects the UAE’s expertise in meeting stringent national regulations and international standards, as well as the leading skills, qualifications and competencies of the Emirati-led teams who have achieved this milestone at the plant.

The Barakah Plant continues to set new benchmarks for new build nuclear programmes. The cumulative knowledge and expertise developed by the operations teams on Unit 1 has been used to connect Unit 2 to the grid more efficiently, with a 10% reduction in the time between start-up and connection while in parallel, ensuring the highest standards of nuclear safety and operational excellence continue to be applied.

With the Unit 2 grid connection successfully completed, the Unit is in preparation to adding a further 1,400MW of clean electricity capacity to the UAE grid, with the first megawatts of emissions-free electricity from this unit now being dispatched to businesses, schools and homes. This milestone takes ENEC and its subsidiaries another step closer to the half-way mark of its goal to supply up to a quarter of the country’s electricity needs 24/7, while driving reductions in carbon emissions - the leading cause of climate change.

During grid connection, the Unit 2 generator was integrated and synchronized with the requirements of the UAE’s national electricity transmission grid, ahead of the start of commercial operations.
With the integration and connection complete, Unit 2’s nuclear operators will begin the process of gradually raising the power levels of the reactor, known as Power Ascension Testing (PAT). Throughout this process, the Unit 2 systems follow international best practice to safely progress and test the Unit as it proceeds towards full electricity production. All of the lessons learned from Unit 1 connection have been integrated as part of Nawah’s commitment to operating excellence.

Once the process is completed, Unit 2 will deliver thousands of additional megawatts of clean baseload electricity for decades to come. This testing will be conducted under the continued oversight of the UAE’s independent nuclear regulator, FANR, which has now conducted more than 335 inspections since the start of Barakah’s development. This is in addition to over 42 missions and assessments by the International Atomic Energy Agency (IAEA) and World Association of Nuclear Operators (WANO).

The Nawah teams at Barakah have worked closely with the Abu Dhabi Transmission and Dispatch Company (TRANSCO), a subsidiary of Abu Dhabi National Energy Company (TAQA), who constructed the overhead lines to connect the Barakah Nuclear Energy Plant to the Abu Dhabi grid – ensuring the power generated at Barakah is safely, securely and reliably delivered to consumers across the UAE.

By powering millions of businesses and households with abundant, clean electricity from the Barakah Plant, ENEC is leading the largest decarbonisation effort in the region, as the Plant now is the largest single source of clean electricity in the UAE and the Arab World.

The Barakah Plant, located in the Al Dhafra region of the Emirate of Abu Dhabi, is one of the largest nuclear energy plants in the world, with four APR-1400 units. Construction of the Plant began in 2012 and has progressed steadily ever since. Units 1 is now producing thousands of megawatts of clean electricity around the clock. Units 3 and 4 are in the final stages of commissioning at 95 percent and 91 percent complete respectively, benefitting from the experience and lessons learned during the construction of Units 1 and 2.

The development of the Barakah Plant as a whole is now more than 96 percent complete. When fully operational, the plant will produce 5.6 gigawatts of free carbon electricity for more than 60 years to come.
