Research Project Summary Information

Compressed Air Energy Storage(ST11052-1)



NY electrical utilities are required, under the Renewable Portfolio Standard (RPS) Program, to obtain a minimum of 25% of their electrical power supply from renewable resources by the year 2013. Transmission congestion in the electric grid raises the cost of electricity and reduces system reliability for all users. Balancing the loads and generation resources on the grid will be significantly assisted by implementing compressed air energy storage (CAES) systems.

Project Description

Using the findings from the prior Feasibility study, the Contractor will select a geographic physical site, and configure the turbo-machinery, design and equipment purchase for a Compressed Air Energy Storage (CAES) facility to be built. With site selected and system configured, the contractor will obtain permitting, regulatory approvals, transmission interconnection, and develop the control scheme to implement the CAES facility. A startup and testing plan will be developed, and once the plant is functionally operating, data that depicts the demonstration results, will be collected and reported to NYSERDA.


1. Large-scale energy storage systems can be effectively operated, in conjunction with intermittent wind and solar resources, to level power output. 2.CAES plants have the potential to provide significant voltage and frequency support within the NYISO ancillary services markets. 3.Energy storage technologies can reduce congestion on the electric power delivery system and thereby reduce location-based marginal prices.
