“…It is possible to notice that the service availability is much lower than the system availability and, in the case of renewable power plants, this represents one of the most important disadvantages because energy cannot be easily stored, unless the power plant is provided with a sophisticated system of batteries that, only in recent applications, are becoming popular (e.g. [62,63]). Table 10: Comparison between the results of service availability in respect to the demand of Figure 17.…”

Renewable energies are a key element of the modern sustainable development. They play a key role in contributing to the reduction of the impact of fossil sources and to the energy supply in remote areas where the electrical grid cannot be reached. Due to the intermittent nature of the primary renewable resource, the feasibility assessment, the performance evaluation and the lifecycle management of a renewable power plant are very complex activities. In order to achieve a more accurate system modelling, improve the productivity prediction and better plan the lifecycle management activities, the modelling of a renewable plant may consider not only the physical process of energy transformation, but also the stochastic variability of the primary resource and the degradation mechanisms that affect the aging of the plant components resulting, eventually, in the failure of the system. This paper presents a modelling approach which integrates both the deterministic and the stochastic nature of renewable power plants using a novel methodology inspired from reliability engineering: the Stochastic Hybrid Fault Tree Automaton. The main steps for the design of a renewable power plant are discussed and implemented to estimate the energy production of a real photovoltaic power plant by means of a Monte Carlo simulation process. The proposed approach, modelling the failure behavior of the system, helps also with the evaluation of other key performance indicators like the power plant and the service availability.

Access to electricity is vital for the social and economic development of a country. Nevertheless, electrification is still a major challenge, especially for countries in sub-Saharan Africa (SSA). Growth in access to electricity in total numbers has slowed down in recent years. Namibia in particular appears to be in a predicament, since a large portion of its widespread population cannot be connected to the main grid at reasonable costs. Furthermore, Namibia relies heavily on imports of coal-based electricity, which limits the country’s ability to achieve its pledged sustainability goals. This is quite paradoxical as Namibia has one of the highest solar irradiation levels in the world, providing the possibility to generate large amounts of solar electricity at very low costs and to electrify rural areas through solar off-grid systems. These favorable conditions should be exploited, not least in view of the growing demand for energy, which potentially exacerbates the present situation. This paper therefore presents firstly general challenges for off-grid electrification and subsequently illustrates the effects in Namibia on the example of two off-grid areas in Gam and Tsumkwe. Several deficiencies within the country’s current off-grid approach are revealed, most notably the one-sided off-grid legislation and the neglect of educational outreach to the local community.
