Vattenfall inaugurates Scandinavia’s largest offshore wind farm. Vattenfall announced on September 6 that it had inaugurated the 604 MW Kriegers Flak facility, a new offshore wind farm located in the Baltic Sea, 15 to 40 kilometers (km) off the coast of Denmark. The wind farm, which covers an area of ​​132 km² and involved the laying of 170 km of submarine cables, is the largest offshore wind farm in Denmark and Scandinavia to date. The Danish parliament gave the green light to the project in 2012. Vattenfall set up the first foundation in May 2020 and installed the first of its 72 Siemens Gamesa SG 8.0-167 DD wind turbines earlier this year. Siemens Gamesa said it had safely installed the 72 turbines ahead of schedule despite the pandemic.

Unit 2 of the Barakah nuclear power plant starts up successfully. Unit 2 of the Barakah nuclear power plant in the Al Dhafra region of the Emirate of Abu Dhabi, United Arab Emirates (UAE), successfully started up on August 27, five months after the start of commercial operations of the first unit of the nuclear power plant, said its owner Emirates Nuclear Energy Corp. (ENEC). Nawah Energy Co., a nuclear operation and maintenance joint venture between ENEC and Korea Electric Power Corp. (KEPCO), hailed this achievement as an indicator of “significant progress” to commission the four units of the plant. “This milestone marks the point where the Barakah plant became the region’s first multi-unit plant, further fueling the country’s economic growth with cleaner, more reliable and abundant electricity,” the company said. When fully operational, the four units of the plant will have a total capacity of 5.6 GW.

TNB is developing a 300 MW hydroelectric power station in Malaysia. The wholly owned subsidiary of the Malaysian utility Tenaga Nasional Bhd (TNB), TNB Power Generation Sdn Bhd, has received a notification from the country’s Ministry of Energy and Natural Resources to develop a 300 MW hydroelectric power station in Kelantan. In a document filed on September 7, the utility said the project would be built by a new wholly owned subsidiary, TNBPG Hydro Nenggiri Sdn Bhd. TNB has estimated that the project will take five years. Its expected commercial operation date is June 1, 2027, the company said. The plant will significantly increase TNB’s existing installed hydropower capacity by 2.5 GW. Over the past 72 years, TNB has operated only three hydroelectric dams: the 1.2 GW Sungai Perak project; the 622 MW Cameron Highlands program; and the 665 MW Kenyir program. Currently, hydropower accounts for 18% of the generating capacity of Peninsular Malaysia of TNB. Coal-fired electricity represents 45.6% and gas-fired electricity 35.9% of its total capacity. The company, which has assets around the world, says it is embracing a low-carbon economy and will support renewables and energy efficiency as part of its efforts to reduce greenhouse gas emissions. tight.

X-Energy creates a subsidiary dedicated to TRISO fuel. X-energy, a US developer of the Xe-100 Generation IV advanced reactor, decided in mid-August to operate its fuel division as a wholly owned subsidiary called TRISO-X. The division will commercially develop the company’s proprietary isotropic tristructural fuel (TRISO) for the growing advanced nuclear power industry. Pete Pappano, vice president of fuel production at X-energy, will lead the new company as president. X-energy has announced that it is ready to begin commercial production of TRISO after years of refining its manufacturing processes for TRISO. New TRISO-X division set to launch commercial facility to meet Xe-100 deployment schedule that calls for at least four Xe-100 modules to be brought online in Washington state by 2027. Plans are also underway for a second fuel fabrication. installation in Canada to serve the Canadian market. The move responds to Ontario Power Generation’s (OPG) decision to build a small modular reactor (SMR) at its Darlington nuclear power plant in Clarington, Ontario, as early as 2028. Last year, OPG began work on advanced engineering and design for this project by choosing three SMR developers: GE Hitachi, Terrestrial Energy and X-energy. However, while the utility says it has not yet “absolutely decided that it will be one of those three,” it plans to select an SMR provider for Darlington at the end of this year.

Siemens Energy and CTCI win contract to build 1.1 GW HL class gas plant in Taiwan. A consortium of Siemens Energy and Taiwanese engineering, procurement and construction company CTCI Corp. announced on September 7 that they would build the 1.1 GW Sun Ba Power Phase II combined cycle power plant in southwest Taiwan for independent power producer Sun Ba Power Corp. The project, which will operate on regasified liquefied natural gas, will use Siemens HL class technology. Sun Ba II is designed as a multi-shaft combined cycle power plant, in which two gas turbines and a steam turbine each drive their own electric generators. The supply from Siemens includes the power station supply island, consisting of two SGT6-9000HL gas turbines, one SST-5000 steam turbine, three SGen6-2000P generators, two recovery steam generators heat and SPPA-T3000 control system. Siemens Energy will also provide long-term service for basic plant components. Scheduled to be commissioned in mid-2024, the plant is expected to become “an important part of Taiwan’s energy transition,” which aims to shift from coal and nuclear power to environmentally friendly gas-fired power plants. environment and renewable energies.

A court cancels the license for Germany’s youngest coal plant. Datteln 4, a 1.1 GW coal-fired power station in the German region of North Rhine-Westphalia which was commissioned in May 2020, was built and started operation despite an invalid development plan, a German higher administrative court ruled on August 26. victory for the plaintiffs, including an environmental group and the town of Waltrop, it does not prohibit the operation of the plant, which is a modern power plant with an efficiency of over 45%. However, the court noted that legal proceedings against the plant’s operating unit were currently pending before another higher administrative court. Uniper said he still believes the permit is legal, and unless required by law, he has no plans to shut down the plant. In a call for results on Aug. 11, Uniper CEO Klaus-Dieter Maubach told investors his company plans to take the plant offline by the end of 2038, in accordance with German law on phasing out coal. “Recently, in its new climate protection law, the German government significantly increased the greenhouse gas reduction target for 2030,” he noted. “For the energy industry, this means that the old trajectory of reduction from 257 million tonnes in 2020 to 175 million tonnes in 2030 has been further reduced, even down to 108 million tonnes in 2030. If a new German government wants to talk about phasing out coal in this context, so we’re ready to talk. Of course, these talks must also cover the issue of compensation, ”he said.
