Using microgrids offers an ideal platform for renewable-energy sources, such as wind energy, to be used more extensively, says turnkey energy project solutions provider SEM Solutions national sales manager Tiaan Hendriks. Renewable-energy sources, such as wind and solar photovoltaic (PV) energy, cannot be solely relied on for constant energy supply, as such an exclusive reliance on renewable-energy sources can result in intermittent energy supply, he adds.
