Gas Turbine Enhancement Project at the Black Point Power Station

The Black Point Power Station (BPPS) is undertaking a Gas Turbine Enhancement Project across four “C” units from 2025 to 2028. The project commenced with the successful implementation of upgrades to Unit C8 in 2025, which included upgrading the combustors and hot gas path components within the gas turbine using a state-of-the-art design to optimise performance and efficiency.

The key outcome of the project was a 0.7% increase in thermal efficiency, which resulted in reduced fuel consumption and air emissions. The project delivered an overall 1% decrease in NO_X, SO₂, RSP and CO₂ emissions.

Apart from reducing air emissions, the project also supported circular economy objectives by extending outage intervals for critical materials by 33% and increasing the replacement intervals for hot gas path components by 33–50%. These measures further reduced maintenance costs and waste, and optimised spare parts inventories, contributing to more sustainable operations.
