Compressed Air Energy Storage

Loading the player...

Dresser-Rand pioneered the development of Compressed air energy storage (CAES) technology and complete CAES solutions more than 20 years ago.

CAES is a method of storing energy that is generated at one time and using it at another by compressing air. Utilities can use this to store excess energy that is generated during off-peak times and store it for later use to meet higher, on-peak demand periods. The ability to extract energy from renewables such as wind and solar, store it, and use it when needed is a growing need in the power industry.

Dresser-Rand pioneered the development of CAES technology and complete CAES solutions more than 20 years ago when we designed and supplied the entire turbomachinery train and controls for the first CAES plant in North America. Learn more about this facility.

SMARTCAES® – A Smart Choice for Many Utilities.
We have continued our commitment to CAES by offering a complete upgraded, integrated rotating equipment system through our SMARTCAES® technology. Dresser-Rand SMARTCAES technology gives utility operators the means to operate their base load plants more efficiently and provides a solution for balancing the grid. It enables renewable energy sources, such as solar farms and wind turbines, to be matched with daily and weekly requirements for electricity.

  • Increases efficiency — CAES facilities enable utilities to optimize base load units by minimizing load swings, maximize efficiency and extend unit life. Storing energy lets you use off-peak power to meet peak demand.
  • Flexible cycling options — Our split-train CAES system allows simultaneous operations of compression and generation trains, allowing separate marketable services including: power, voltage, and frequency regulation, controllable load, and reserve capacity, as well as other benefits.

Environmental Advantages — CAES can be an important asset for grid operators to mitigate the effects of intermittence and variability of renewable resources. Ability to capture and store renewable energy, such as wind and solar power, prevents the curtailment of renewable assets and maximizes the amount of available renewable energy delivered to the market.
