The Robert D. Green Generating Station in Webster County, Kentucky now burns natural gas instead of coal after a recent conversion project.
The 500 MW Green plant is part of the Sebree Generating Station, owned and operated by Big Rivers Electric.
The electric co-op was required to stop using the site’s two coal-fired units by June 2022 in order to comply with environmental regulations.
Big Rivers partnered with Burns & McDonnell for the plant conversion. Burns & Mac served as the project development and detailed design engineer for the project.
The scope included project management and controls, project development and cost estimating, equipment specs, contract management for equipment and construction contracts, design of the installation packages, construction management, and startup and commissioning.
The EPC said existing systems were used to generate full capacity with minor modifications to the ductwork and windboxes without a need for pressure part replacements or a flue gas recirculation system, while still achieving steam temperature.
Green Generating Station was commissioned in the 1970s.
