Wood Group GTS has completed a maintenance contract worth $2 million for Frame 5 and 6B gas turbines at power stations in Costa Rica and the US. 

Taking steps to enter the Chinese market, Alstom has signed a long term agreement to license its GT13E2 gas turbine for manufacture, assembly and sales in China through the Harbin Turbine Corporation (HTC).

Siemens is contracted to provide long-term service for Blackhawk Power Station – a 230-megawatt gas-fired cogeneration facility located in Borger, Texas.

Californian consumers could save up to $890 million per year, or 11 % in system level generating costs, by replacing 5.5 GW of gas turbines with an equal amount of Smart Power Generation (SPG), a KEMA DNV study finds.

GE is celebrating "20 years of powering progress around the world" as its LM6000 aeroderivative gas turbine that achieved more than 26 million operating hours.

Dehumidification is key for keeping a mothballed power station operationally ready while protecting it from corrosion or degradation during its temporary closure, says Carl Webb who worked with Andrews Sykes when Barking Power Ltd. temporarily closed one 500MW unit at its gas-fired power plant.

News in Brief

Ferrybridge C gets demolished

Oct 15 – Four cooling towers at the Ferrybridge Power Station have been taken down as the coal-fired power station will make way to a new, high-efficiency gas power station. Operator SSE shut down the 500 MW Ferrybridge C unit in March 2016 and now started to tear it down.

Global energy storage tops 10 GW by 2025

Oct 14 – The global market for grid-connected energy storage will grow by 6,900 MW, or 16.6% to reach over 10,500 MW by the end of 2025, according to Reportlinker.com. Germany will add over 267 MW energy storage installations over the next five to six years, while 330 MW will come from other European markets. These numbers are dwarfed by China, where up to 1,200 MW energy storage units could be connected to the grid by 2025.

Wärtsilä services EDL plant

Oct 11 – Energy Developments Ltd (EDL) of Australia has awarded Wärtsilä a service contract for gas engine-based baseload power plant at the McArthur River zinc mine in Northern Territory. The maintenance approach for the 53 MW onsite power plant is no longer pre-planned and scheduled but has been changed to condition-based and predictive maintenance, with an advisory contract.

EPH buys CCGT in Galway

Oct 10 – The Czech energy company EPH has received regulatory approval to purchase an 80% stake in the 400 MW Tynagh Energy combined-cycle gas power plant in Galway, Ireland. Mountainside Partners will continue to own the remaining stake in the CCGT, which operates based on a security-of-supply contract from the Irish TSO based on guaranteed power prices.

ITM gets £38m boost from Linde

Oct 9 – Sheffield-based ITM Power, maker of electrolysers for hydrogen production, has been boosted by a £38 million cash injection, as Linde acquired a 20% stake in ITM at 40 pence per share. Looking ahead, ITM said it is seeking to raise £14 million from new and existing institutional investors.

Drax to convert two power units

Oct 8 – Drax Group has received government approval to convert up to two coal-fired generating units at its power station in North Yorkshire to run on natural gas. With this ruling, the UK regulator overturned objections by ClientEarth, stressing some fossil power is vital for the UK to backup intermittent renewable power source.

Storage use tops 80% in key U.S. regions
