Predictika · Gas turbine power island and service agreement quotes

An AI sales agent's gas turbine quote, checked before it goes out

An AI sales agent prepares a gas turbine power island and long-term service agreement quote for a fictional customer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the output, fuel, emissions, start, service, payment, lead time and discount rules, compares the quote total the agent states with the one it computes, and returns a verdict with every reason.

Scope: Siemens Energy-style gas turbine power islands (SGT-400, SGT-750, SGT-A35 and SGT-800) with a long-term service agreement: site output, fuel and emissions, black start, service agreement coverage, payment terms, lead time, discount authority and the stated total. See everything this validator covers

This validator models a gas turbine power island and service agreement quote, not just the scenarios shown below.

  • Output and plant design — site output after ambient temperature and altitude derate, units in service with N or N+1 redundancy, simple or combined cycle, and start time to full load.
  • Fuel, emissions and black start — dual fuel on the turbines that offer it, hydrogen blend limits per combustion system, the NOx permit limit against the turbine's guarantee (selective catalytic reduction needed below it), and the black-start diesel package.
  • Service agreement, payment and pricing — a service term of 6 to 20 years whose equivalent operating hours must reach the first major inspection, cyclic-duty approval, down payment minimum and milestone, buyer credit, delivery lead time against the date needed, discount authority by equipment value, and the quote total the agent states against the one computed.

Any gas turbine quote that touches these rules is in scope — not only the scenarios pictured here. All ratings, derates, emissions figures, inspection intervals, prices, service rates, lead times and discount tiers are estimates for demonstration, not Siemens Energy data. Not covered: other turbine models, steam turbines and generators beyond the combined-cycle add-on, taxes, financing and real delivery slots. The validator shows computed figures but no line-item table.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Output at site conditionsOnly with workarounds
Heat and altitude derate, units in service and redundancy combine into one computed output, which usually becomes a formula plus a validation rule per turbine.		The output is computed from the turbine data and compared with the requirement on every call.
Fuel, emissions and black-start optionsOnly with care
Each option rule is simple, but the turbine-specific limits (hydrogen share, dual fuel, NOx guarantee) multiply as models are added.		Limits are read from the turbine data, so a new turbine needs data, not new rules.
Service agreement term and hoursOnly with workarounds
Hours depend on running hours, starts and term together, and must be compared with a turbine-specific inspection interval.		The equivalent operating hours are computed and compared with the inspection interval.
Payment terms and buyer creditOnly with care
A down-payment floor, an approval band and a credit condition need separate rules.		All thresholds are evaluated together and returned with the reason.
Discount authority by project sizeOnly with care
Tiers that change with the equipment value mean a price rule or approval rule per band.		The approvable maximum is computed from the equipment value.
The total the agent statesOnly with workarounds
Comparing a stated total with a computed one means a separate rule per quote layout, and price rules rarely run on stated figures.		The stated total is a field in the request and is checked against the computed total.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the quote is saved, so a rep often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases
Click to expand
    
Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
162.0 MW available is less than 5 percent above the 60.0 MW required; performance guarantees need engineering sign-off.
210 percent down payment is below the 15 percent standard milestone; finance must approve.
310 percent discount is above the 3 percent a sales manager can give; approvable up to 12 percent.
4350 starts per year is cyclic duty; LTSA pricing needs service-risk approval.
55 percent discount is above the 3 percent a sales manager can give; approvable up to 7 percent.
6106.4 MW available (53.2 MW per unit at 35 C and 100 m, N redundancy) is below the 110.0 MW required.
731.85 MW available (31.85 MW per unit at 25 C and 0 m, N_Plus_1 redundancy) is below the 40.0 MW required.
830 percent hydrogen exceeds the 15 percent the SGT-A35 aeroderivative gas turbine combustion system is rated for.
9Permit limit 15 ppm NOx is below the 25 ppm DLE guarantee; add SCR.
10Black start on the SGT-800 industrial gas turbine needs the black-start diesel package.
11Start to full load takes about 45 min; the customer requires 30 min.
12LTSA term 4 years is outside 6 to 20 years.
1330,000 EOH over the LTSA term does not reach the first major inspection at 40,000 EOH.
145 percent down payment is below the 10 percent minimum.
15A sub-investment-grade buyer needs at least 20 percent down or a letter of credit.
16Delivery takes about 24 months; the customer needs commercial operation in 20.
1715 percent discount exceeds the 12 percent that can be approved on EUR 106,000,000.0 of equipment.
18Dual fuel is not offered on the DLE SGT-A35 aeroderivative gas turbine.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares a gas turbine power island and long-term service agreement quote for a fictional customer. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the output, fuel, emissions, start, service, payment, lead time and discount rules, compares the quote total the agent states with the one it computes, and returns a verdict with every reason.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please quote 1 Siemens Energy SGT-800 gas turbine in combined cycle on a hydrogen blend (80 percent hydrogen), 70 MW required at 35 C and 100 m. Quote total €48,189,600.00. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with twelve findings, all in one answer. 53.2 MW available (53.2 MW per unit at 35 C and 100 m, N redundancy) is below the 70.0 MW required. 80 percent hydrogen exceeds the 75 percent the SGT-800 industrial gas turbine combustion system is rated for. Permit limit 9 ppm NOx is below the 15 ppm DLE guarantee; add SCR. The other nine are on screen.
    6. 
      
  6. The validator returned twelve blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other and against the stated total.
    7. 
      
  7. What this shows: for service agreement term and hours, a rules-based CPQ can do this only with workarounds.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the turbines to 2, the hydrogen share to 50 percent and the stated quote total to €123,568,000. It sets the SCR to yes and the black-start diesel package to yes. Six more changes are on screen.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. This time the validator clears it.
    12. 
      
  12. All twelve earlier findings are cleared.
    13. 
      
  13. Twelve problems caught in one call, fixed in one pass, and a clean 123,568,000 euros quote. That is the value of Predictika's validator: catching mistakes before they reach the customer.
    14.
