Mexico was hit by rolling blackouts on 7 May due high temperatures and drops in power generation.
The government’s National Centre for Energy Control said the blackouts lasted for a total of up to five hours, and was a rolling blackout distributed around the country. The centre said the largest power cut affected about 5 per cent of customers and lasted about four hours.
The blackout was caused by a combination of a spike in domestic power demand in the early evening, exacerbated by the high temperature, and a drop in power generation resulting from a number of factors including lower output from hydropower plants as a result of low water levels and clouds affecting solar power output.
