Brownfield Engine Exchange (BEX)

Upgrade existing gas-fired power plants with BEX

As the pace of the energy transition accelerates, upgrading or optimizing existing gas-fired power plants has emerged as a more viable option than constructing new ones. Thanks to technological advancements and improvements in energy efficiency, retrofitting older facilities presents a cost-effective means of enhancing output while simultaneously mitigating emissions. With Siemens Energy's Brownfield Engine Exchange concept, old gas turbines can be seamlessly replaced with new ones within a short outage period.

The Brownfield Engine Exchange (BEX) solution is designed based on a plug-and-play concept, providing a streamlined retrofitting process that yields improved performance and efficiency for your gas turbine. By integrating our latest H2-capable gas turbines into your asset, BEX can also help future-proof your operation. BEX operates on three guiding principles:

Provide the flexibility to maintain the existing steam cycle or update it based on your future requirements
Develop a tailored solution that fits your unique needs, by involving transparent discussions about layouts, business cases, and Balance of Plant calculations
Integrating the new gas turbine package while reusing as many existing infrastructure components as possible, i.e. filter house, exhaust channel, foundation, and generator

Improved efficiency and power output
Significant savings on fuel cost, CO2 tax and maintenance cost
Fast start and load capability
Extended outage intervals
Greater fuel flexibility thanks to the latest DLE technology focusing on renewable fuels (H2 and biofuels)
