Tackle the challenges of flexible plant operation

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.To maintain profitability and efficiency, conventional generation must achieve increased flexibility in terms increased start-ups, reduced generation loads and fuel variability.

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 comprehensive plant flexibility solution

Our Economic Flexible Operation solution offers a full 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.

Improve your efficency
Optimize fuel costs by understanding the impact of cheaper and blended fuels, and optimizing your plant accordingly. Reduce running costs by moving your focus to predictive maintenance, reducing daily maintenance costs by 10-20%.
Maximize your income
Take advantage of commercial opportunities with flexible operation capabilities, with a shortened stat up time by 20-50%. Enjoy market modelling and forecasting of grid requirements, seasonal demand and fuel cost fluctuations.
Reduce risk
Analyse the changes in risk due to flexible operation, and prioritize the issues and investments to mitigate those risks. Explore our range of digital tools to manage the data required to manage the risk and ensure safe and efficient performance.
Protect and extend component life
We help you reduce major component replacement costs by 20-30%. Determine the effects of flexible operation on components, and target maintenance and inspection, as well as ensuring staff have the correct training and understanding to manage flexible operation assets.


Unlock the true value of your assets and maximize profitability with Enerlytics. Our IoT platform for the energy industry gives you a 360-degree, end-to-end view of your plant or portfolio and the autonomy to make better decisions for financial gain and market leadership.

Parts life extension

Unlock significant cost savings by extending your gas turbine parts life and major outage intervals beyond the normal OEM maintenance interval, typically by 15-30%. Our structured methodology for PLE, underpinned by technical expertise identifies opportunities for interval extensions, with detailed technical evaluation. Using component modelling, including blue light scanning, CFD and FE analysis, metallurgical evaluation of service run components, advanced inspection techniques with boroscope, NDT inspection of critical components and image recognition algorithms we can address identified risks, propose outage interval extensions and regularly review to monitor and manage risk during operation.

Discover what our gas plant experience means for you

Timely alert of blockage avoids forced outage

Our monitoring of condition data from key components gives an independent view of plant health, allowing issues to be detected days, weeks or months in advance of a failure, while site teams are able to concentrate on operational priorities.

Combined expertise avoids major turbine failure

One of the key benefits of our monitoring services is the early detection of developing faults and providing rapid alerts so that clients can take timely action. Our support goes far beyond data gathering and analysis – it’s the result of a combination of expertise and long experience as an owner operator of generation plant.

Fuel Challenge Solution Benefit
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%)
