Taiwan Power Company has awarded a contract worth 130 billion Japanese Yen ($1.17bn) to GE and its EPC partner Marubeni for the DaTan 8&9 project. The upgrade will see GE equip the units with four HA turbines, boosting output to over 2,000 MW.
After more than a century in operation, Alabama Power’s 1,221 MW Plant Gorgas will be shut down as retrofits, mandated under Obama-era regulation, would be too costly to run it at a profit. Retrofits related to the handling of coal ash would cost around $300 million, said the operator, who now takes steps to shift to cleaner fuels.
Reciprocating internal combustion engines – typically used for backup, standby, or emergency power – are playing a fast advancing role in utility-scale power generation applications, according to EIA findings. In Texas alone, the share of gas-fired recip engines surged 20% to over 4,600 MW largely as a reaction to the state’s rapid growth in installed wind power capacity.
Today’s power grids are becoming increasingly complex as more decentralized power sources are added, requiring the network to carry bulk power in ways it was never designed to do. Recent order wins for GE’s Fixed Series Compensation (FSC) total over $60 million as TSOs turn to the technology to enhance flexibility of the grid.
Proposals to put a price on carbon emissions – in the form of a CO2 tax – will not be realise in the current legislative period, Germany’s energy state secretary Andreas Feicht said. The Conservative-led Government had earlier dismissed the initiative, saying it was not in the governing coalition’s agreed agenda.
To stabilize power supply in Guinea, MAN Energy Solution will install six 18V32/40 engines in a power plant near the capital city Conakry. The 53 MW power plant is being set up on behalf of Guinea’s Tè Power Company in collaboration with the Turkish EPC company Iltekno.
Mitsubishi Hitachi Power Systems (MHPS) has won an order to supply a turbine and other components for a blast furnace gas (BFG)-fired combined-cycle plant build to power operations of the Chinese steelmaker Maanshan. Operations of the 180 MW plant are scheduled to start at the end of 2020.
The Japanese energy majors JERA and Tepco Power Grid have agreed to jointly invest up to $32.68 billion (£25 million) in Zenobe Energy, a UK-based battery storage company. Zenobe owns and operates some 73 MW of batteries and is currently looking to use its technology in related business areas, notably the charging of electric vehicles.
The Japanese trading house Itochu has pulled the plug on investments in thermal coal mines and coal-fired power projects. Having just sold its stake in the Rollestone mine in Queensland, the Japanese firm said it seeks to increase the renewables ratio in its power plant portfolio to over 20% by the end of fiscal 2031.
Electricity, not natural gas, will drive the compressors of the Annova LNG export project in a bid to lower the facility’s carbon footprint. Developers already signed an agreement with the South Texas Electrical Cooperative (STEC) for supplies of 405 MW of electricity to cool and liquefy up to 6 mtpa of LNG.
On the market for nearly a decade, the Siemens H-class gas turbine has now exceeded one-million fired hours in commercial operation. The output rating of the SGT5-8000H turbine has grown over the years from 375 MW to 450 MW, with efficiency improvements to over 61% in combined cycle operation.
Ground has been broken on the Montgomery County Power Station, a 993-MW combined cycle gas turbine plant under construction next to the existing Lewis Creek Power Plant in Willis, some 46 miles north of Houston. For Energy Texas it is their first plant in 40 years, and due operational by mid-2021.
Burning hydrogen (H2) in a combined-cycle power plant is a step towards dispatchable, totally CO2-free power generation. However, the main challenge of H2 combustion lies in its properties, notably its increased reactivity. In contrast to natural gas, the flame position moves upstream during H2 combustion, which increases the risk of flashback.
Bangladesh’s Ministry of Power, Energy and Mineral Resources and Siemens have signed a joint development agreement for the construction of an integrated LNG regas and power generation project. The 3,600 MW plant will be built at Payra, a small seaport in southern Bangladesh.
Abundant supply of cost-competitive shale gas, combined with technological advances, has led to an ever-increasing average size of a combined-cycle gas power block in the United States. While the average CCGT had about 500 MW installed capacity before 2014, the power block capacity has since then increased to an average 820 MW, according to the EIA’s electric generator report.
