The off-grid project has 10 kW installed solar photovoltaic capacity to generate solar power during day time and 10 kW wind power from small wind mills, each having a capacity of 200 watt. A battery bank with 120 batteries of 300 AH capacity each, is installed to store the energy generated and it will provide back-up for upto five days. The system will initially be operated and maintained by BORG for one year.

The electricity generated will be used to illuminate 20 LED lighting systems.
