Assessing Electrical Transmission Constraints for the Southern African Power Pool (SAPP) in PLEXOS®
December 19, 2014 === === The SAPP was formed in 1995 and as of 2013 had sixteen participating members transforming from an initial co-operative electricity market into a competitive one in 2009. The SAPP has been significantly constrained for generation and transmission capacity in the last decade having a significant effect on the volume of electricity trade. A regional level SAPP model has been developed in PLEXOS including a representation of load profiles, existing transmission interconnectors and existing major generators. The case study reveals that existing energy imbalances in SAPP countries can be significantly reduced if interconnectors are unconstrained allowing for optimal trade of electricity between SAPP nations.
