Abstract:

This paper presents the design of a cost-effective stand-alone electricity generation system with a storage option for Dedelo farming community in the Eastern Cape province in South Africa using plant biomass feedstock. Average load for the community is estimated to be 338.88 kW with a peak load of 1 510 kW and average energy consumption of 8 133 kWh/day, respectively. A plant-based biomass resource assessment of Dedelo was carried out. A cost, technical and environmental analysis was made for each of the proposed case studies. The most cost-effective system was found to be that of the biomass gasifier hybridized with diesel generator and storage with Net Present Cost and Cost of Energy. The system had no capacity shortage, no unmet load and no excess electricity.

I. Introduction

The population with access to electricity in Sub-Saharan Africa in 2019 was only 47.9%, with South Africa as an exception to this as 94.3% of the population had access to electricity [1]. In 2018, 89.6% of South Africa's rural population had electricity access compared to 92.1% of the urban population [2]. One reason for the lower percentage of electrification in rural South Africa is lack of access to utility grid where grid extension may not be economically viable. This is because rural areas have low incomes, low energy and the households are scattered [3]. A viable electrification option for such rural areas is development of stand-alone renewable electricity generation by hybridizing the locally available biomass with a more stable energy source such as a diesel generator.
