David Moz­er­sky is the Found­ing Direc­tor of the Pro­gram on Con­flict, Cli­mate Change and Green Devel­op­ment. An expert on Sudan and South Sudan, he has been involved in con­flict pre­ven­tion efforts in Africa since 2001, with a spe­cific inter­est in medi­a­tion, nego­ti­a­tion and peace processes. He has worked with the Inter­na­tional Cri­sis Group, the African Union High-​​​​Level Panel on the Sudans, and Human­ity United, among oth­ers. He has writ­ten exten­sively about the con­flicts and peace­mak­ing efforts in the Horn of Africa, and has tes­ti­fied or pre­sented before the U.S. Sen­ate and House of Rep­re­sen­ta­tives, the Cana­dian Par­lia­ment, and South Sudanese Par­lia­ment. David has authored and co-​​​​authored more than two dozen Inter­na­tional Cri­sis Group reports and brief­ing papers, and his writ­ing has appeared in the Har­vard Inter­na­tional Review, Inter­na­tional Herald-​​​​Tribune, Finan­cial Times-​​​​Europe, and other publications.

Strategic siting and regional grid interconnections key to low-​​carbon futures in African countries

Recent fore­casts sug­gest that African coun­tries must triple their cur­rent elec­tric­ity gen­er­a­tion by 2030. Our mul­ti­cri­te­ria assess­ment of wind and solar poten­tial for large regions of Africa shows how eco­nom­i­cally com­pet­i­tive and low-environmental–impact renew­able resources can sig­nif­i­cantly con­tribute to meet­ing this demand. We cre­ated the Mul­ti­cri­te­ria Analy­sis for Plan­ning Renew­able Energy (MapRE) frame­work to map and char­ac­ter­ize solar and wind energy zones in 21 coun­tries in the South­ern African Power Pool (SAPP) and the East­ern Africa Power Pool (EAPP) and find that poten­tial is sev­eral times greater than demand in many coun­tries. Sig­nif­i­cant frac­tions of demand can be quickly served with “no-​​regrets” options—or zones that are low-​​cost, low-​​environmental impact, and highly acces­si­ble. Because no-​​regrets options are spa­tially het­ero­ge­neous, inter­na­tional inter­con­nec­tions are nec­es­sary to help achieve low-​​carbon devel­op­ment for the region as a whole, and inter­con­nec­tions that sup­port the best renew­able options may dif­fer from those planned for hydropower expan­sion. Addi­tion­ally, inter­con­nec­tions and select­ing wind sites to match demand reduce the need for SAPP-​​wide con­ven­tional gen­er­a­tion capac­ity by 9.5% in a high-​​wind sce­nario, result­ing in a 6–20% cost sav­ings, depend­ing on the avoided con­ven­tional tech­nol­ogy. Strate­gic selec­tion of low-​​impact and acces­si­ble zones is more cost effec­tive with inter­con­nec­tions com­pared with solu­tions with­out inter­con­nec­tions. Over­all results are robust to mul­ti­ple load growth sce­nar­ios. Together, results show that mul­ti­cri­te­ria site selec­tion and delib­er­ate plan­ning of inter­con­nec­tions may sig­nif­i­cantly increase the eco­nomic and envi­ron­men­tal com­pet­i­tive­ness of renew­able alter­na­tives rel­a­tive to con­ven­tional generation.
