energy growth by enhancing the reliability and stability of the grid, challenged by grid limitations in the northeastern part of the Polish power system, says GE. It is GE’s second H class gas turbine order in Poland, after Dolna Odra, currently under construction.
“In this decade we expect growth in electricity demand and phase out of the oldest coal fired power plants,” said Daniel Obajtek, CEO of PKN Orlen and acting CEO of Energa SA. “Therefore, Orlen Group invests in…power plants with the ability to supplement renewable energy sources”.
As well as the 9HA.02 gas turbine (with DLN 2.6e combustion system, and its potential future hydrogen capabilities), GE’s scope includes an STF-D650 steam turbine, a W88 generator, a heat recovery steam generator and a Mark* VIe
distributed control system. GE will also be EPC contractor.
GE claims “currently the quickest ramp rate in the industry” for the 9HA.02 gas turbine, 88 MW per minute in single shaft combined cycle configuration.
“Once in operation and supplied with gas from the Poland–Lithuania interconnector, Ostroleka will contribute to increasing the security of power supply in the country”, said Amit Kulkarni, head of product management for heavy duty gas turbines, GE Gas Power.
For this project, the steam turbine will be manufactured locally in GE’s steam turbine factory in Elblag, Poland, while the manufacturing of the generator will take place in GE’s factory in Wroclaw, Poland. The gas turbine will be manufactured in Belfort, France.
Two 7HA.02 gas turbines recently entering service were those at the Indeck Niles Energy Center, Niles, Michigan. On 1 July, Indeck Energy Services, along with its Korean partners KOSPO and DL Energy, officially notified the PJM Interconnection of the start of commercial operation of the new power plant. Indeck says it developed the project to meet the need for generating capacity created by the decommissioning of older, more costly and/or less-efficient coal fired and nuclear plants in the region.
The plant, built by Kiewit, consists of the two GE 7HA.02 gas turbines, plus two H65 generators, an STF-D600 steam turbine powering a H84 generator, and two heat recovery steam generators, with a Mark* VIe distributed control system.
Mitsubishi Power to do mega upgrade at Datan
Mitsubishi Power has received a series of contracts from state-owned Taiwan Power Company (TPC) to carry out a large-scale renovation project of power generation equipment at the Datan power plant in the city of Taoyuan, 50 km west of Taipei
The contract covers four natural gas fuelled combined cycle blocks (units 3 to 6 at the site), with a total of eight gas turbines. The aim of the renovation project is to reduce emissions of NOx
while maintaining generating capacity, allowing the plant to comply with increasingly tight environmental regulations, as well as to enhance operating flexibility via O&M improvements. Completion is scheduled for 2025.
The Datan power plant has a total of 20 gas turbines (including those in units 8 and 9, currently under construction), and is one of the largest natural gas fired power plants in Taiwan. Once all units are completed and operational, the plant will have a total combined installed
capacity of about 7000 MW. Mitsubishi Power has supplied 14 of the gas turbines, for units 1-6. Units 1-2 employ six M501F machines, while the remaining eight are M501G gas turbines. It is these M501G machines that will be progressively upgraded under the new contracts with Mitsubishi Power. To reduce NOx
emissions, the current
combustors will be replaced with air-cooled, premix combustors, which lower local
combustion temperatures and curb NOx generation, decreasing NOx
around 60%.
At the same time, Mitsubishi Power will install new gas turbine components along with the TOMONI digital platform with the
emissions by
aim of increasing operational flexibility while maintaining high generating capacity. Taiwan continues to face a tight power supply/ demand situation, Mitsubishi Power notes, with producers unable to keep up with robust demand. The country needs to increase its capacity margin and high expectations have long been attached to gas fired power generation. Taiwan has adopted an energy policy that includes abolishing nuclear power by 2025, with 50% of electricity coming from gas fuelled combined cycle power plants, 30% from coal, and 20% from renewables. At the same time, there are increasing calls to reduce environmental impacts, requiring lower NOx
emissions and increased power plant efficiency.
