Valuing Flexibility in CCS Power Plants

The objectives of the FlexEVAL study were to investigate the need for flexibility and the value of flexible CCS power plants in the UK electricity system. It addressed the role of firm, dispatchable, flexible CCS capacity on long-term carbon intensity. Findings showed that, while both flexible and non-flexible CCS technologies led to a reduction in total system cost, flexible CCS technologies provide additional value to the electricity system by enabling it to accommodate hjosirer levels of intermittent renewable capacity, reducing total system cost further through increased electricity dispatch from intermittent renewables with low operational cost. It is recognised that policy mechanisms would likely be required to encourage the uptake of sufficient flexible CCS in the future electricity grid to achieve these advantages.
