About IECM
The IECM is a computer-model for preliminary design and analysis of clean electricity generation technologies employing fossil fuels. It is intended for use by engineers, researchers, technology developers, and policy analysts to systematically analyze the cost and performance of fossil fuel power plants of various types and emission control designs. The IECM allows users to easily design the plant to be modeled, and to get results quickly for a variety of technology options.

Probabilistic Analysis
A unique capability of the IECM is that it also allows the uncertainty or variability of performance and cost results to be rigorously characterized using probabilistic analysis. Uncertainties can be analyzed individually or collectively across the entire set of plant components and sub-systems.
