Hybrid energy systems are a combination of two or more renewable
energy sources such as PV (photovoltaic), wind, micro-hydro,
storage batteries and fuel powered Gen-sets to provide a reliable
off-grid (a source of energy not connected to a grid) supply.
Currently, there are two pilot hybrid systems in the Eastern
Cape at the Hluleka nature reserve on the Wild Coast and at
the neighbouring Lucingweni community:
The Hluleka hybrid mini-grid system consists
of two proven 2.5 kW wind generators and three Shell Solar PV
module arrays fitted with 56 100-watt PV modules wired in series
(total 10.6kW). An integrated design approach, which resulted
in a joint energy, water purification and telecommunication
system was followed. The energy system makes use of renewable
energy (wind and solar), solar water heaters and LPG (Liquid
Petroleum Gas) One diesel generator is retained for back-up
supply. The Hluleka system has been in operation since June
2002.
The Lucingweni hybrid system consists of 50kW
solar PV panels and 36kW wind generators serving 220 dwellings
(four lights per dwelling, radio, television, cell phone charger,
street lighting, telecommunications and water pumping).
Data
and information on the two pilot hybrid systems is being gathered
to analyse their viability and whether they can be replicated
throughout South Africa. |
