Changes in the energy market, in particular the rapid growth in generation from renewable sources such as wind and solar, present significant new challenges for the operators of coal- and gas-fired power plants.
As an owner operator with decades of experience, we understand the impact of renewables, and of changes in the energy market and environmental legislation. We have first-hand experience of successfully implementing flexible operation in our own coal- and gas-fired plants.
Our independent condition monitoring found an air-heater fault a month before the issue would have become critical. Read more
An early warning from our Advanced Condition Monitoring prevented catastrophic failure and minimized turbine damage. Read more
A complete solution
Our Economic Flexible Operation solution offers a comprehensive range of support services in a single package focusing on economic efficiency, maximizing income and reducing risk.
We will work with you throughout the complete process of introducing flexible operation, from identifying commercial opportunities, through modifying plant procedures and avoiding component damage, to achieving economic gains by reducing maintenance costs and extending plant life.

Coal-fired generation - Expertise based on owner operator experience
Gas-fired generation - Independent gas plant solutions
|Coal||Large temperature differentials in unit hot / warm start resulted in increased tube failures, loss of income and increased maintenance costs||Implement a furnace off-load pumped recirculation system||Significantly reduced temperture differentials across furnance. Corrosion fatigue and tube failures reduced|
|Gas||Reduce low load operation at 429 MW single shaft plant||Implement of CO reduction package, install 50 additional thermocouples for early detection of instabilities and ability to approach real HRSG load limit||Final settings in pre-defined load range from 210 MW to 190 MW. Resulting CO emissions at 190 MW:13mg/NM3|
|Coal||Avoid life reduction due to increasing unit starts. Avoid start-up oil consumption. Take advantage of summer and night-time opportunities. Maintain commercial operation||New minimum load point determined. Test and demonstration program carried out. Boiler and turbine capabilities established. Stable operation confirmed||Pmin reduced from 180 MW design to 90 MW (10%)|
