NRECA International has been engaged by OnePower to carry out an evaluation of the financial and technical impact of converting OnePower’s existing mini-grid designs into the first Single Wire Earth Return (SWER) systems used in solar mini-grids in Sub-Saharan Africa. This analysis includes design guides and drawings to implement SWER, and training for engineers and lineworkers to manage this new system, resulting in cost reductions of 10-30% compared to conventional medium voltage networks.
