This brief will focus on enablingregulations for mini-grids, providing an overview of keyissues, options, and good practices. While appropriateregulations are not all that is needed to spur mini-griddevelopment, is usually one of the first obstacles thatpotential developers face and therefore the most urgentissue for governments. The authors draw on a case study ofTanzania, a pioneer in setting an enabling and light-handedregulatory framework for mini-grids. Given the urgency ofleveraging private sector investments for reaching theuniversal access targets of the international sustainableenergy for all projects, the authors also focus onregulatory issues relevant to private sector entrepreneursand investors. Mini-grid entrepreneurs need to know thattheir investment of time and money will have a reasonablechance not just of being repaid but also of returning aprofit. A clear and credible regulatory framework that makesand enforces fair and efficient decisions in a timely mannerhelps entrepreneurs make informed investment decisions. Thekey characteristics of such a framework, described includelicensing and registration, tariff setting, and what happenswhen the main grid reaches the mini-grid.
