Cost of 100mw compressed air energy storage in saint lucia

What is compressed air energy storage?

Compressed air energy storage (CAES) is one of the many energy storage options that can store electric energy in the form of potential energy (compressed air) and can be deployed near central power plants or distribution centers. In response to demand, the stored energy can be discharged by expanding the stored air with a turboexpander generator.

What are the PCS costs at 200 MW?

For large-scale storage at 200 MW, it was anticipated that the PCS costs could decrease to $140/kVA. It is not clear what this translates to in terms of $/kVA for the one to two orders of magnitude lower power levels investigated in this report for BESS.

What is the cost of C&C for a solar system?

The same report predicted that C&C costs for the system would be between $150–$180/kW. Aquino et al. (2017b) estimated the battery cost to be in the $200–$500/kWh range; the PCS and system controls cost was estimated to be approximately $150–$350/kWh and electric BOP cost to be between $80 and $120/kW.

What is the cost of energy storage?

The cost of energy storage varies by technology. According to a 2018 report by RedT Energy Storage, the cost of their Gen 2 machines starts at $490/kWh.

How much does energy storage cost in 2025?

The red diamonds in the figure provide a forecasted cost for each energy storage technology for the year 2025 on a $/kWh-yr basis. Pumped storage is forecasted to cost $19/kWh-yr in 2025 when compared on an energy basis using 2018 values.

What is the cost of a 100 MW CAES plant?

Aquino et al. (2017a) estimate that for a 100 MW CAES plant, fixed O&M costs will be approximately $19/kW-yr.
