1. How does SigmaPOWER™ work?
SigmaPOWER™ is based on, ASME’s “Performance Test Code” and international respected scientific thermodynamic, chemical and mechanical literature. Upon technical base, middle and top manager’s demands were taken into consideration while creating system architecture and interface.
To use process data in SigmaPOWER™, we have to acquire and archive process data first. For this purpose you can use databases whatever you prefer. SigmaPOWER™ suits all well-known databases. Such as Oracle, PI etc.
Process data in database make contact with SigmaPOWER™ by “Tag Connection” interface.
In this step, signals from field are assigned to appropriate tags in system architecture. After assigning process data, plant architecture is created in “System Design” interface. Whole plant is structured hierarchical from top to bottom. Plant architecture can be structured such as only an individual HRSG or whole plant. And also more plants could be manage in one control group. This feature gives us a chance to manage a number of different type plants with their interaction between each other.


2. How much should i invest in SigmaPOWER™?
Investment in SigmaPOWER™ depends on which level at your plant that you can see Figure 1. Such as; if your plant at DCS level, you need database before implementation of SigmaPOWER™. If you made all preparations before, it is easy and cheap to implement SigmaPOWER™ system.

3. How long is payback time?
Payback time depends on how big is your plant, which tools you will use and where is your plant at Automation Pyramid which mentioned at question 2. (see Figure 1)
· Your plant size will directly effect on payback time of your investment. It means the bigger plant size, the shorter payback time.
· And also full package of SigmaPOWER™ Performance Monitoring and Optimization System can help to get maximum profit fast.

4. How long does implementation take?
It depends on your level at automation pyramid. Every preparation extends implementation period of SigmaPOWER™ system. Though, setting pre-steps up under the SigmaPOWER™ supervision will take less time than you expect.


5. Should i shut down my plant for implementation?
While implementing of SigmaPOWER™ Performance Monitoring and Optimization System no shut down is required.

6. How much energy cost savings will be earned at the end of first year after implementation?

Energy cost savings of SigmaPOWER™ varies between 1 or 3 percentages and of the first year. The energy saving is related to your fuel consumption and your strategy.

7. How will SigmaPOWER™ effect on plant employees?
You can manage both your plant equipment and plant operators. Right order on right equipment to right man will complete the chain. Energy awareness and plant culture are basic results of SigmaPOWER™ Performance Monitoring and Optimization System.
