Conduit Hydropower Potential in City’s WDS
P1-1
FeasibilityPayback period
• The preliminary cost for the pilot plant totalled R550 000.
• This was for the turbine and generator, electrical work, pipework, valve chamber, enclosure/plant housing, monitoring system and data logging and communication system.
• Annual income could be in the order of R130 000 for electricity generated based on 100 c/kwh.
• Assuming a discount rate of 10% and a very optimistic energy escalation rate of only 8% results in a payback period of ±5 years (IRR = 28% for 20 year design life).

• Why develop large hydropower? – Economically feasible – Garsfontein #1 and others
• Why develop smaller conduit hydropower schemes?– On site use of electricity– Upliftment of community
• Free internet access for an area?• Free electricity for a school?• Mass lighting?
– Improved operational control of WDS• Telemetry• Security/Alarm system• Site lighting
• Identification and development of other water infrastructure with hydropower potential
