This paper explores the prospects for expansion and transition of the electricity system in Bolivia, in a context of growing sustainability goals and climate commitments, considering that the country is highly dependent on fossil fuels and primarily managed by the state. It reviews this by integrating scenario-based expectations for the development of Bolivia, which has historically relied on a short-term planning approach and has finally established some long-term goals, seeking to expand its electricity system and integrate renewable energy into the mix, both in 2030 and 2050 plans. Three development scenarios are proposed: implementation of existing plans, expanded availability of natural gas, and a net-zero emissions scenario. The analysis of the power systems uses PyPSA-BO, a model adapted to reflect Bolivia's specific characteristics. The analysis concludes that, although there has been progress in energy planning, achieving a real transition will be a greater challenge than the one currently provided by the government, requiring policies that integrate the electricity sector into a broader and more sustainable energy framework.
