Building on its commitment to supporting the energy infrastructure in Sudan, Siemens has signed a long-term agreement with the Sudanese Thermal Power Generating Company (STPGC) to provide service and maintenance for the power generating assets and related components operating at the 337 megawatt (MW) Port Sudan and 502 MW Garri power plants.
On January 24, 2018, the most powerful high-voltage direct-current (HVDC) transformer began its journey from the transformer factory in Nuremberg, Germany, to China. The transformer will first be transported to the harbor in Nuremberg by special heavy load transporter, where it will be loaded onto a ship. Its journey will take it to Rotterdam via the Main-Danube Canal, and from there it will be shipped to China, where it will arrive after several weeks on the high seas. In July 2016, Siemens received an order to manufacture four transformers of this type. About a year later, the world’s first 1,100 kV transformer was completed and successfully passed the tests in the testing facility. The enormous dimensions of the transformer – 37.5 meters long, 14.4 meters tall, and 12 meters wide – posed a logistical challenge for the team. In operation, the transformer weighs just under 900 tons and its efficiency is well above 99% of the rated power. For the first time, the transformer will enable a high-voltage direct-current (HVDC) transmission with low losses over a record distance of 3,284 kilometers with a transmission capacity of 12 gigawatts. HVDC transformers are part of the converter station that convert alternating current into direct current at the beginning of the transmission line and convert it back again at the end of the line. The conversion from alternating current to direct current helps to transmit energy over long distances with low losses. Transformers are key components of an HVDC line: Thanks to the transformer, the Changji-Guquan project will be able to transmit direct current with a huge 1,110 kilovolts for the first time in the world. The new transformer not only makes the transmission of this record voltage level possible, but it is also the world’s most powerful tested transformer with a capacity of 587 megavoltamperes. Siemens has thus achieved a new dimension in high-voltage direct-current transmission. The HVDC line between Changji and Guquan will be operated by State Grid Corporation (SGCC), a Chinese grid operator. The connection is expected to begin operation in 2019.
Scandinavia is the first region in the world to rely increasingly on battery-powered and thus environmentally-friendly technologies in the shipbuilding industry. After "Ampere", the world's first electrical ferry in Norway, and a follow-up order of the Finnish shipping company FinFerries, Siemens has now received an order from Norwegian ferry operator Fjord1. Ampere was put into operation in Norway in May 2015, and has traveled a distance equivalent to more than 1.5 times around the equator. With the change from diesel propulsion to battery, Norwegian ship owner Norled has reduced the cost of fuel by 60 percent. Now Siemens has tailor-made a suitable technical solution for Fjord1. With this contract, the first four battery-driven ferries in the world will run on technology developed and manufactured by Siemens.
"Elektra" - the newest member of the electric ferry fleet: In June 2017, the Elektra began regular operation between Nauvo and Parainen in the Turku archipelago. Battery packs, which are charged via the land-based charging stations in the harbor for use by the ferry, serve as the primary source of energy, with Diesel engines used as emergency power units. The Elektra is also Europe's largest car ferry. At nearly 98 meters long and 16 meters wide, the Elektra can transport up to 90 cars per trip. The ferry purchased by FinFerries will now be traveling this route every 15 minutes. The batteries will be charged in roughly five minutes while cars move off and onto the ferry. The two lithium-ion batteries each have a capacity of 530 kWh.
