General Electric (GE) has launched its GT26 HE (high efficiency) gas turbine platform upgrade for German energy company Uniper’s power station in Enfield, North London.

The GT26 HE upgrade will expand on the current technology GE use in its F and H class turbines. This includes advanced combustor engineering that reduces cooling requirements by 15%, lower emissions and 3D aero-profile compressor configuration to increase base and part-load performance. GE will also use technology from French multinational company Alstom, as GE bought its power division in 2015.

The upgrade will increase the plant output from 15MW to 55MW per unit. It will also have a 2% increase in base load and 1% part load efficiency, leading to a total of $5m in fuels savings per unit annually. Savings will also be made on maintenance costs, as inspection intervals will increase from 24,000 to 32,000 hours.

Uniper’s Enfield Power station will be the first to install the turbines in 2020. GE says it sees the UK and Europe as its most crucial market for the GT26 turbine, with 59 of its 100 GT26 turbines installed on the continent.

GE CEO Scott Strazik said: “We’re proud to launch out new GT26 HE upgrade with Uniper, it’s the most advanced solution we’ve ever introduced on a GT26 gas turbine, and one of our most efficient upgrades within the F-class portfolio.

“Not only will this upgrade revitalise Uniper’s Enfield power plant, it will also improve its competitive position in the UK generation market, supporting its long-term profitability and viability.”

Uniper chief operating officer Eckhardt Rummler said: “We’re very pleased to be working with GE on this new technology upgrade. In the UK’s very competitive and challenging power generation environment, investing to keep our plants competitive by lowering operational and maintenance costs at the same time as increasing efficiency and flexibility is critical for the long-term success of our fleet.”
