Résumé : This paper analyses the potential transitional direct and indirect macroeconomic impacts of an electricity price increase due to the entry of new large data centers in an economy without excess energy capacity. It tracks the short term distributional, employment, fiscal, sectoral and growth effects of the associated electricity demand shock, if the prevailing electricity price regulation remains unchanged. The quantitative analysis is based on a computable general equilibrium model calibrated for Argentina. The simulations suggest that the failure to adjust the pricing regulation could lead to a short run output drop in the industrial and service sectors. This would increase unemployment and worsen income distribution since the shock hurts less the highest income class in relative terms.
