Study of renewable energy resources found within local municipalities: An eThekwini municipality case study

Abstract

Under-frequency load shedding, rising electricity tariffs, environmental concerns and delays in constructing new power stations had plunged South Africa into darkness and constant need for load shedding. This has led consumers and producers alike to explore various energy generation options to assist the sector to meet its electricity demands whilst reducing their electricity needs. Renewable energy technologies with its short lead times have become an attractive alternative for the country and hence led to the South African Government calling upon the country to explore renewable energy generation options. Subsequently, the Integrated Resource Plan 2010 set a target of 17 800 MW (equivalent to 42%) of new electricity generation capacity to be derived from renewable energy sources. This paper assesses the availability of renewable energy resources within a local municipality that can be harnesses to generate much needed clean energy. Various sectors within the municipal environment were studied to determine the availability of generation potential ranging from landfill gas, biogas, hydro, wind and solar PV. The eThekwini Municipality was assesses in this case study to determine the available renewable energy resources within a local municipality.
