Dominican Republic heat wave drives record electricity demand and widespread outages

Dominican Republic electricity demand heat wave blackouts protests

Extreme heat in the Dominican Republic has pushed the perceived temperature in Santo Domingo to as high as 48 °C, prompting a surge in electricity use. National demand peaked above 4,400 MW during July evenings, with a recorded high of 4,330.8 MW on a single night, far exceeding typical peak levels of around 3,000 MW.

The overload has caused rolling blackouts lasting up to seven hours in multiple districts of Greater Santo Domingo, including Bajos de Haina, Los Mina, Villa Mella, Pedro Brand and others. Residents have staged protests and cacerolazos, burning tires and blocking streets in neighborhoods such as El Limón, Cayenas, Amalia and other residential complexes. Electricity distributors blame the outages on the sharp rise in consumption driven by air‑conditioner and fan use during the heat wave.

Authorities are negotiating an interconnection of El Limón with the Santa Bárbara substation in Samaná to improve voltage and reliability, a plan overseen by the Samaná governor Teodora Mullix and the local distributor El Progreso. The situation remains critical as high temperatures persist and the national grid faces continued strain.
