In this context, productive use is not merely additional to domestic use, but often complementary, as it helps smooth the time profile of electricity consumption: while the peak period for domestic use is the evening (for lighting and entertainment), productive use occurs primarily during the day. Accordingly, the expansion of productive uses of energy may also be conducive to supporting the penetration of variable renewable technologies, especially in the case of solar energy. In line with box 6.1, tackling supply-side constraints within a context of strong demand growth and investment dynamism is thus a key factor in successful development strategies.
