electricity - 2025 ACF Fall

Question

Note to moderator: read the answerline carefully. Maasai pastoralists have been displaced by projects providing this service located in Kenya’s Olkaria (-5[1])region. Husk, a company that provides “mini” methods (-5[1])of providing this service, (-5[1])left Tanzania over disputes with TANESCO. (-5[2])Morocco provides (-5[1])this service (-5[1])through complexes like one at Noor, (10[2])which uses a parabolic (10[1])trough collector (10[2]-5[2])as a (-5[1])“concentrated” (10[1]-5[1])facility (10[2])of its type. (10[4]-5[3])This (10[2])service is (-5[1])intended to be supplied (10[1])across Africa (10[1]-5[1])by the much-delayed (-5[1])Grand Inga (-5[2])infrastructure (10[1]-5[2])project (10[2]-5[4])in (10[1])DR Congo. (10[6]-5[5])In South Africa, Eskom’s failure (10[2])to fully (10[2]-5[1])provide (10[3]-5[1])this (10[1])service (10[10]-5[6])has led (10[1])to (10[1])loadshedding. (10[6]-5[2])For 10 (10[2])points, (10[2])what (10[1])service (10[2])may be conveyed (10[1])as (10[1])HVDC from photovoltaics (10[2])or (10[1])batteries? (10[2])■END■ (10[44]0[1])
