Gas Turbine Correction Curves
Over time gas turbines age or are upgraded. The curves you got at commissioning are probably out of date or have never been checked for accuracy. If you’re looking for a low-cost, easy way to track expected performance, new correction curves are the way to go.
Are you associated with an OEM?
No, we work with the OEMs, but the correction curves are made independently of the OEM and are constructed using your data.
Who are you? Can I trust your correction curves?
Great question! We are a team of engineers with more than 100 years of combined experience working with gas turbine OEMs, owners, and operators. Some of us have designed next generation hardware. We have also designed next generation monitoring techniques for gas turbines and renewable power plants. We have provided this service upon request in the past and correction curves are usually accurate to within 1% or less. Enough people have asked for it we’ve decided to offer as a standalone service.
How do I know your correction curves are accurate?
Another great question! We provide an accuracy report with each set of curves. This accuracy report is very detailed and let’s you know how accurate curves are for various weather conditions. We also provide uncertainty around each curve on plots provided back to you.
Do I just get back plots or do I get the equations too?
You get back the equations too! They can be formatted to run in pretty much anything! (Excel, major historians, etc.)
How are your curves different from the OEM?
Two ways, 1) we prove to you the curves are accurate. 2) We calculate the curves based on your data, not generic models or general effects.
This sounds pretty good, how much does it cost?
See pricing below:
- One Time Setup fee (per site): $5,000 (regardless of number of gas turbines)
- Curve generation (per Gas Turbine): $1,000 includes:
- Accuracy report
- Plots of new correction curves
- New equations for power, heat rate, heat consumption, and air flow. Curves are generated for baseload, peak, and part load performance.
Do you make combined cycle curves too?
This is something we have been considering adding on. If you’re interested in correction curves for your steam turbine, contact us and let’s talk details.
I’m sold, how do I start?
Fill out our contact form below, then we’ll need 6-12 months of site data on a one-time basis for each gas turbine. It usually takes 1-2 weeks to turn around the curves back to you. We’ll schedule a meeting to review them and answer any questions.
Do you do periodic updates?
We can – the cost will depend on frequency of updates but contact us to discuss. The cost to update or assess current accuracy is usually less than the cost of new curves.
