Economic and regional impacts of investments in electricity generation in Brazil To comply with climate agreements, Brazil intends to raise the share of non-hydro renewables in electricity supply. According to the Brazilian Decennial Energy Plan (PDE 2026), the country will expand its installed capacity in the period 2017-2026 mostly by investments in gas, wind and solar sources. However, areas suitable for those projects are regionally concentrated and, in some cases, in the poorest regions such as the Northeast. Hence, the expansion of power supply also have economic and regional implications that could be enhanced according to the configuration of the electricity matrix. Despite that, there is still a gap in the literature regarding to this topic. We explore this analyzing the economic and regional impacts of the investments in electricity generation, under various policy scenarios provided by the PDE 2026. For that, we apply a regional recursive-dynamic CGE model for Brazil, TERM-BR10, specially enhanced to deal with electricity features. TERM-BR10 has eight electricity generation types (wind, solar, hydropower, biomass, gas, diesel and oil, coal and others) and allows substitution between them in a regional level. For simulation purposes, we assume the expansion of electricity matrix of Case 8 from PDE 2026 as our baseline. In fact, this expansion is the one with less policy interventions. As our policy scenarios we assume: Case 1 (reference scenario), Case 4 (scenario with reduction in cost of investment for solar) and Case 5 (no new hydro dams). Our results show that in comparison to the baseline a supply plan with more insertion of solar source, as Case 4, could increase the national GDP by 0.45% and by 2.15% in specific regions. In this case, the Northeast regions are the most benefited. The results also show that a scenario without new hydro dams does not imply in economic loss, in terms of national GDP or employment. This is quite relevant, specially when take into account that environmental concerns have been raising for hydro projects. Besides, we also came to the conclusion that policy guidelines have welfare and distributive benefits, with greater impact to poorest regions and low income households.
