Improve Your Plant's Performance 
with EtaPRO Fuel Demand Model (FDM)

The EtaPRO FDM system accurately models the plant fuel demand and heat rate in real time. The FDM Virtual Plant model provides a highly detailed thermodynamic mass and energy balance of your plant that aligns with contract commitments and predicts hourly contract parameters.

Combined with the PASS system, the FDM offers a streamlined method for generating invoices, ensures transparency for all parties, and is easy to review and adjust.

Smart Error Handling

Ensure anomalies like non-incrementing meters or offline equipment are flagged and managed.


Complete Data Control

All user inputs are securely stored for the entire contract term.


Simplified User Experience

Entering outage details is quick and intuitive. Generate invoices and more with precision.


Put Smarter Plant Management to Work

Whether your facility produces electrical energy, water, or both, the EtaPRO® FDM & PASS System adapts to complex contract scenarios supporting PPA, WPA, and PWPA agreements with precision, transparency, and confidence in every transaction.
