LCOE of US$0.60/kWh needs to be more than halved to allow for an affordable cost- reflective tariff. Upfront cost per connection for mini-grids is around US$500–2,100, similar to the unsubsidized cost for traditional grid connections. In remote areas, mini-grids are the preferred options for electrification as grid extension costs increase.
Solar-hybrid mini-grid LCOE can be reduced by 60% and reach US$0.22/kWh by 2030 by leveraging hardware cost reduction, remote monitoring technology, system standardization, demand stimulation, low cost financing and minimizing regulatory barrier. “Six ways to reduce mini-grid costs by 60% for rural electrification”.
Understanding different mini-grid cost metrics supports informed decision-making. For instance, the levelized cost of energy (LCOE) accounts for all costs spread over the lifetime and load profile of a mini-grid, including capital expenses (CAPEX), operating expenses (OPEX) and therefore is an indicator for the cost-reflective tariff.
Remote monitoring of power generation, storage and consumption can cut mini-grid O&M cost by 30% (LCOE by 4%) by reducing the number of site trips and prolonging component lifetime, therefore cutting labor, logistics and component replacement costs. (AMMP, p.7,10,13; RMI, p.18)
