As summer drives peak electricity demands and price volatility, Wet Compression adds up to 10–15% additional gas turbine output on demand, so you can respond fast when price spikes hit and dependable MWs matter most.
Wet Compression is a solution designed to help operators recover and monetize performance during hot summer conditions, when temperatures and humidity reduce turbine output. Results depend on unit configuration and site conditions.
Is Wet Compression a fit for your plant?
Wet Compression is typically strongest for plants with:
Exposure to peak pricing during summer months.
Temperature driven derates or performance risk in hot and humid condition.
Capacity obligations where dependable MWs are critical during summer and grid stress periods.
Wet Compression introduces controlled amounts of high pressure demineralized water into the compressor inlet. This reduces inlet temperature, improves compressor efficiency, and increases air mass flow, delivering additional power above base load for defined operating periods. The system is intended for operation during hot ambient conditions and is typically deployed seasonally to address summer performance loss.
Two high-value use cases for Wet Compression
1. Capture revenue during peak demand
When high value intervals are short, you need additional MWs now, not later. To seize these peak windows the moment they appear, generation flexibility must be immediate and controllable.
Problem: When prices surge, the plant may not be able to increase output beyond base load fast enough to monetize short, high value intervals.
Solution: Wet Compression delivers on demand additional output that can be applied during peak intervals (depending on configuration and site conditions).
Capacity payments depend on delivering dependable MWs, especially during summer and grid stress conditions, when high temperatures erode available output. Maintaining confidence in peak period delivery requires a way to recover that lost capacity.
Problem: Dependable MWs can drop during hot months, increasing non performance risk during grid stress events, impacting capacity payments and penalties.
Solution: Wet Compression provides additional dependable MWs to support reliable delivery during high demand periods (site/config dependent).
