Ecuador electrical grid stability concerns

Overview

By October 11, 2026, the Mazar reservoir reached a critical level of 2,125 meters above sea level, leaving it only 10 meters above the minimum threshold for safe operation. Data from Celec Sur shows the reservoir has lost approximately 26 meters since late July, with recent declines accelerating to between 1.2 and 1.5 meters per day.

While previous technical estimates suggested remaining water might last 13 to 15 days, the rapid depletion rate could bring the reservoir to its critical limit as early as October 20. Hydroelectric consultant Ricardo Buitrón warned that if current trends persist, the remaining 35% of water could be exhausted in roughly 14 days, a scenario that might extend power outages from the industrial sector to residential homes.

As of October 14, 2026, water inflow to the Mazar reservoir has dropped to approximately 14.6 cubic meters per second, a 51% reduction from earlier that morning. In the Cuenca region, rivers such as the Tomebamba, Yanuncay, Tarqui, and Machángara are reporting low flow rates. Experts from Etapa EP noted that while occasional showers have occurred, they have not been sufficient to recharge water sources because the soil remains dry. High temperatures and intense solar radiation are also accelerating evaporation. Authorities indicated that at least two weeks of continuous rainfall in recharge zones is required to stabilize the water supply and mitigate national electricity shortages.

Claims

What the coverage asserts, and how many sources carry each claim.

[● 2 SOURCES] Minister Juan Carlos Blum announced that 150 industries will disconnect for one full day per week starting September 22, 2026.
[○ 1 SOURCE] The Ministry expanded scheduled electricity cuts for industries to 48 hours starting in October.
[○ 1 SOURCE] Approximately 8,600 medium voltage companies in Ecuador will disconnect from the grid one day per week.
[● 4 SOURCES] The disconnection could save between 1,000 MW and 25% of daily demand.
[● 2 SOURCES] Arconel approved a tariff reform for high voltage 1 (AV1) and high voltage 2 (AV2) consumers.
[● 2 SOURCES] The new tariff will apply to consumption in October, November, and December 2026.
[● 2 SOURCES] The goal is to reduce consumption to preserve reservoir levels during the dry season.
[○ 1 SOURCE] The Mazar reservoir level reached 2,138.8 meters above sea level, which is 14.2 meters below its maximum allowed level.
[○ 1 SOURCE] The disconnection applies to regulated consumers in the AV1 segment, representing approximately 90% of industrial consumers in that group.
[○ 1 SOURCE] The severe drought is linked to the El Niño phenomenon affecting the Amazon basin.
[○ 1 SOURCE] The average price for AV2 consumers will be 29 cents per kWh and 30 cents per kWh for AV1.
