AFS value calculator: Fuel savings and carbon reduction

An expanded emissions compliant load range can make your power plant much more flexible to better complement intermittent renewables and avoid the alternative of more frequent and costly cycling. GE’s Axial Fuel Staging (AFS) upgrade can help you cost effectively adapt to an increasingly renewables-rich power grid while staying in emissions compliance, and reduce both total emissions and your carbon footprint.

How much can you save? Tell us a little bit about your equipment and how you’re running today, and our calculator will build a custom scenario to help you plan for the future.

GE’s AFS Value Calculator will help you:

  • Learn how you can save money due to reduced fuel burn from operating your plant at a lower minimum load, all while staying in emissions compliance

  • Discover how operating at a lower minimum load can reduce plant shutdown/startup cycling, and thus avoid plant start-up costs, start-up emissions, and plant cycling wear and tear
