Subscribers use information from GKS Fossil® generation benchmarking to:

Better understand their plant operations

Companies need to understand where they excel and where they need improvement. By comparing plant operations at a detailed level against peer units, GKS Fossil® helps subscribers as they choose areas for improvement, and provides insight into the potential impact actions may have on their performance and budgets.

Take an asset optimization approach to managing the fleet

Since all plants have a different risk/reward profiles, how companies invest their capital and maintenance dollars – and the return on these investments – is key to their financial success. GKS Fossil® provides companies access to information and analysis that supports decisions about how to increase the return on their asset investments.

Gain insight into future challenges and opportunities

By coupling information gleaned from GKS Fossil® with market/asset management tools, subscribers can increase their understanding of the challenges facing their generating plants, and adjust to proactively meet both today's growing energy needs, and plan for the future.
