Flexible solutions from a single source
Dresser-Rand can supply the entire CAES train. Our teamwork reduces your project management time, and single-source packaging minimizes transaction and transportation costs.
We custom-engineer each CAES train to provide you with a system designed specifically to meet your site's operating and geologic requirements. We select and fine-tune standard Dresser-Rand components for your project, then we make sure that all components will work together to maximize efficiency, and reduce installation and start-up times. Systems can be configured for salt caverns, hard-rock caverns, aquifers, or depleted natural gas fields on land or sea.
What makes CAES a smart choice for many utilities?
- Increases efficiency and extends base load unit life: CAES facilities enable you to optimize your base load units by minimizing load swings to maximize efficiency and extend unit life. Storing energy lets you use off-peak power to meet peak demand. This is less expensive than using traditional gas turbine peaking units or purchasing power from other sources.
- Responds quickly: A CAES generator is designed to be started and brought to full load in as little as 10 minutes, eliminating the need for intermediate- load plants and providing a cost-effective way to meet spinning reserve requirements. CAES generators also have excellent load-following capability and very good part-load efficiency. Compressors can be engaged quickly to absorb load rather than reducing your base load generation.
- Flexible cycling options: The CAES system is available for compression duty when it's not in power generation mode, and can be configured for daily, weekly, or extended cycles. This allows you to "grid balance," and use inexpensive power for air storage (charging).
- Environmentally Friendly: CAES has environmental advantages compared to conventional gas turbines because its combustors use as little as two-thirds the fuel. Furthermore, CAES can be an attractive alternative to the costly modifications required to make coal-burning plants comply with increasingly stringent fossil fuel emissions requirements./li>
