SAPP member states plan more transmission interconnectors BUSINESS INTEL Batoka Gorge will be the third dam on the Zambezi River. By Eamonn Ryan Ministers of the Southern African Development Community (SADC) have accepted a strategy proposed by the Southern African Power Pool (SAPP) that can save the region USD36-billion in installed capacity by 2040, by avoiding rigidity due to excessive ‘committed’ megawatts.

The savings come from sharing surplus capacity through an integrated transmission network. Three plans were prepared by consultants to deliver the same 36 | CEC February 2019 amount of power: the installed capacity in Plan C (the approved option) is 130GW, 3GW higher than B and 14GW lower than A. The overall cost of C is USD259-billion, only USD5-billion higher than B but USD36-billion (or 12%) lower than the total cost of A. Moses Ntlamelle, SADC senior energy officer, described the SAPP ministerial decision to adopt SAPP Plan of 2017 as a guiding document to direct development of power generation and transmission in the region: • It directed the SADC Secretariat, in collaboration with SAPP Coordination Centre, to convene dissemination workshops at national level on SAPP Plan 2017, as it is expected to add value in the review and development of national integrated resource plans; •  It urged member states to develop their National Integrated Resource Plans, taking into account the SAPP Plan 2017, and to invest and develop interconnector corridors to enhance flexible power trading in the region; and •  It commended the World Bank and other co-operating partners for their support to develop the SAPP Plan, which will be incorporated in the remaining action plans of the Energy Sector Plan of the Regional Infrastructure Development Master Plan (RIDMP) 2018–2027. The 2017 Pool Plan (PP) was prepared under the SAPP planning subcommittee, with technical work performed by a team drawn from five consultancy firms.
