Abstract:
In South Africa there is currently no notable use of modern small-scale hydrokinetic (HK) energy systems, mainly due
to formerly low-cost coal-powered electricity. is renewable energy option makes use of the kinetic energy from owing
water, rather than potential energy, which is more o en used in conventional hydropower. Updated re ned versions of this
technology are now being investigated and manufactured due to the global drive towards reducing carbon emissions and
increasing energy e ciency. ese modular units allow for installation of HK turbines into existing water infrastructure
with very little civil works. e study’s objective was to develop a simpli ed design and implementation process for HK
devices within the South African legislative and regulatory environment. Approximately 66% of South Africa’s water supply
is used by the agricultural sector with more than 6 500 km of canal systems running through many areas which could bene t
from alternative energy sources. e recent electricity crisis in the country allowed for problem resolution through funding
opportunities and thereby an introduction of an innovative and sustainable technology to provide renewable electricity where
otherwise not feasible. A pilot HK project was implemented in an applicable section on the Boegoeberg irrigation canal in the
Northern Cape Province and tested for optimum functionality and correct application. is process allowed evolution of a
development process for the implementation of HK devices in existing water infrastructure.
