A Mini Grid also sometimes referred to as a “Micro Grid or Isolated Grid”, can be defined as a set of electricity generators and possibly energy storage systems interconnected to a distribution network that supplies electricity to a localized group of customers. “They involve small-scale electricity generation (10 kW to 10MW) which serves a limited number of consumers via a distribution grid that can operate in isolation from national grid.

DIMO with its principal Dhybrid Gmbh is currently carrying out the countries’ first mini grid project at University of Moratuwa with Lanka Electricity Company (LECO) and involved in initials stages of such projects in Myanmar.
