Mozambican territory, including alternatives for reliable and quality energy supplies for isolated systems. d) Even if REN continues to expand over time, a part of the Mozambican territory will continue without direct access to it for the period of validity of this strategy and, therefore, dependent on electricity supply systems through isolated systems (SIE ). e) The supply of energy through isolated systems (SIE) will continue to be of great socio-economic and political importance in Mozambique, particularly in the vast rural and peri-urban areas of the country. f) Isolated systems energy supply combines renewable and non-renewable energy supply technologies, including traditional biomass-based energy supply systems and high quality renewable energy supply systems. Whenever possible, these systems prioritize renewable sources over non-renewable sources. g) The use of firewood and charcoal for cooking, particularly in rural and peri-urban areas, makes these geographic areas possible beneficiaries of initiatives originally designed for isolated systems (SIE), even when they are close to REN or RELS, ie classified as systems in -network (SILE). These areas, when benefiting from components of the EDENR-FR Strategy while interconnected to the electricity grid, are designated Mixed Systems (SILE/SIE) h) Mozambique needs to adapt to climate change which over time will have a negative influence on the patterns of demand and supply of energy, especially in rural and peri-urban areas. i) The planning for the expansion of renewable sources, translated into the National Program for New and Renewable Energies (PNENR) which incorporates the aspects of interconnected systems (SILE) and isolated energy systems (SIE), takes into account the geographical diversity of energy resources in Mozambique. To this extent, planning will be geographically specific and, whenever possible, will go down to the level of detail of community planning, through Sustainable Community Energy Plans (PCES). j) There is a need for changes in planning and decision-making processes based on regulations and formal rights, increasingly based on the improvement of prudent evaluation methods. k) There is a need to ensure the existence of qualified labor for the country in order to maintain the energy systems. 8/41
