Steam power from Pilsen
23 September 2020Pilsen-based Doosan Škoda Power plans to deliver two 50 MW DST-G20 steam turbines, plus associated equipment, in the middle of 2021 to Palu 3 – a coal fired plant which it describes
as “the most modern power generating plant in Indonesia.” The project site is in a seismically active area and Doosan Škoda Power says it is building on experience from similar previous projects in Indonesia, as well as in Chile and Saudi Arabia. As Doosan Skoda puts it “the first steam is expected to be invited to the turbines in 2023.”

Doosan S?koda Power is working on the coal fired Palu 3 plant with its parent company Doosan Heavy Industries, which will supply two circulating fluidised bed boilers. The plant is being built for Indonesian government-owned power company, PT Perusahaan Listrik Negara (Persero).
Although rated at 50 MW, the steam turbine design includes “a reserve by which the power output can be raised to 64.5 MW”, says Marke´ta Leitlova´, project manager, Doosan S?koda Power.
Doosan S?koda Power is working with its parent company Doosan Heavy Industries & Construction on the project.
Other recent steam turbine project developments reported by Doosan S?koda Power include the following:
- Successful operation of two 204MW turbines at the 1509 MW Fadhili combined cycle power plant in Saudia Arabia, jointly owned by Saudi Aramco, Saudi Electricity Company and Engie. The two twin-cylinder DST-S10 turbines with no reheat have been operating since March 2020 at the Fadhili plant, located near the Jubail industrial city on the Persian Gulf.
This is Doosan S?koda Power’s first installation in Saudi Arabia, while elsewhere in the Middle East, Doosan S?koda Power turbines can be found, for example, in Zarqa, Jordan (185 MW), and Salalah II, Oman (2 x 89 MW).
- Significant progress, despit eCOVID-19, on the Rookery South Energy Recovery Facility project, an energy-from-waste plant in the UK, for which Doosan S?koda Power is supplying and installing a 67 MW turbine set, on a turnkey basis, with a scope that includes generator, excitation transformer, oil system and high-pressure hydraulic system. Assembly is scheduled for completion by October 2020, with first steam to be generated in March 2021.
Main contractor for the plant is Hitachi Zosen Inova, while the developer is Covanta, in partnership with Veolia and the Green Investment Group.
“We are already implementing similar projects for Hitachi Zosen Inova in Istanbul and most recently in Newhurst in the UK”’ said Toma´s? Stary´, Doosan S?koda Power project manager.
Despite complications caused by COVID-19, the Rookery South turbine was manufactured andshippedtwomonthsaheadofthe deadline specified in the contract, says Doosan S?koda Power. At the beginning of May, C?EZ Distribution engineers assisted with the transport of the turbine, which weighed more than 240 tons, to the Port of Lovosice by lifting the power lines along the route.
- Performance testing and handover of the steam turbine for ASV6 at the Asnæs CHP plant, Kalundborg, Denmark, which Doosan S?koda describes as “a unique double casing steam turbine with flexible coupling of the low- pressure turbine.”
The project is part of a project that will see Asnæs, which provides district heating to the local network and process steam to a nearby pharmaceutical plant, as well as power to the grid, converted from coal firing to biomass, mainly wood chips.
