This paper summarises the results from a study that assesses the performance and costs of natural gas fired combined cycle power plants with CCS. Information is provided on the designs of each of the plants, their power output, efficiency, greenhouse gas intensity, capital costs, operating and maintenance costs, levelised costs of electricity and costs of CO 2 avoidance. Discussion and commentary on the key findings and recommendations is also included. The paper includes information on base
