Dominican Republic Sets New Electricity Demand Record of 4,277 MW

Dominican Republic electricity demand record 4,277 MW summer heat SENI

In late July 2026 the Dominican Republic’s national grid recorded several historic demand peaks. On July 29 the Sistema Eléctrico Nacional Interconectado (SENI) reached a record‑high instantaneous load of 4,277 megawatts (MW) at 20:36 local time, surpassing the previous peak of 4,203 MW set the day before. Earlier in the month the grid had already broken records four times, with loads of 4,166.52 MW on July 16, 4,185.11 MW on July 23, 4,195.26 MW on July 24 and 4,203 MW on July 28.

Minister of Energy and Mines Joel Santos announced the peaks via X, attributing the surge to an intense summer heat wave, rapid economic growth and widespread use of air‑conditioning. The SENI grid met the record load without blackouts, maintaining stable nationwide supply. Energy‑sector expert Augusto Bello warned that, if the trend continues, the country's peak demand could exceed 5,000 MW before 2030.
