Abstract
The main objective of this study is to analyze the system of electric demand in Tunisia and to propose immediate alternative solution of photovoltaic implementation that can be suitable based on available natural solar energy resources in the country to respond to the short Forecast peak demand growth and energy consumptions taking into account financial strain. On the first step, analysis of the situation based on the recent historical data is proposed. In a second step, a solution is considered, based on photovoltaic implementation and using the results of historical data analysis. The resulting benefits are highlighted: financial, technical, environmental and social. Future studies may be made to use a mix of technology and policy as well: among it combining photovoltaic and battery storage, in parallel with energy efficiency programs.
Highlights
Tunisia is a developing country with an extended electric network and an overall 99% electrification
The Tunisian Electric system is suffering from different gaps below enumerated:
The calculated implementation of Photovoltaic system in Tunisia is equivalent to 9500 Tunisian Dinars (TND) per Photo Voltaic (PV) system of 3 kWc free of taxes, based on reference costs obtained by local supplier of PV system
Summary
Tunisia is a developing country with an extended electric network and an overall 99% electrification This is the case of almost all the North African countries. The aim of this study is to resolve within short terms delays, the problem of future gap to respond to demand peaks during summer with immediate implementation of photovoltaic, to keep away from undelivered energy to consumers in the future and to avoid enormous financial costs as well. It is known that since 2010, similar peaks have cost 4 TND/kWh. Other possible mix of solutions: PV is one solution that is directly related to the country natural resources. Using battery storage in complementarities with photovoltaic, or hybrid system, (Kathirvel and Porkumaran, 2014) will imply the advantage to flat the demand load, using MWh of charging during off peak costs and discharging
