The rising energy demands and pressing need for reduction of greenhouse emission necessitates carbon capture technologies an important part of future power systems. While graphical and analytical methods for including carbon capture in power system planning has been explored, this paper suggests an algebraic method for including carbon capture using Pinch Analysis for power system planning. This method first identifies the viability of carbon capture technology in a given system using the concept of prioritised cost. It then allows for calculating the quantity of existing power plants to be retro-fitted. It also takes into account unique aspects of carbon capture technologies: parasitic loss associated with carbon capture units and variation in existing sources that come about with the introduction of a Carbon Capture and Storage (CCS) unit. For example, if existing coal power plants are being retro-fitted, it means that the availability of energy from coal decreases. This interdependency between two energy sources (the CCS unit, and existing power plant) had to be taken into account. The proposed methodology is applied to Indian power sector.
