What Happened
ENSA has announced scheduled preventive maintenance on its electrical network between April 27 and May 3, 2026, as part of routine work designed to keep service safe and reliable. The utility says these activities may include equipment upgrades, vegetation trimming and infrastructure reinforcement to reduce the risk of unexpected outages.
The company is warning customers that the maintenance could cause temporary interruptions in specific areas during the scheduled work windows. Residents and businesses are being encouraged to check whether their property falls within the affected zones before planning their day.
How to Check If You Are Affected
Customers can verify possible service impacts by visiting ENSA’s scheduled interruptions page and entering their NAC. The utility is also directing users to its official website and social media channels for updates on the areas and times of intervention.
The maintenance notice is part of ENSA’s broader effort to keep the distribution network operating under safer conditions. Preventive work of this kind is common in power systems because it helps identify weak points before they become service failures, especially in areas with growing demand or exposed infrastructure.
Why It Matters
For households, scheduled maintenance can mean brief power interruptions, but it also supports longer-term reliability. For businesses, especially those dependent on refrigeration, computers or communications equipment, advance notice allows time to protect operations and back up essential systems.
Vegetation management is one of the most visible parts of distribution-line maintenance, since branches and overhead lines can create faults during storms or high winds. Equipment upgrades and reinforcement work can also improve the stability of service over time.
Public Service Reminder
ENSA’s announcement reflects a standard utility practice: informing customers ahead of planned work so they can prepare for possible interruptions. Consumers across the affected sectors are advised to stay aware of the maintenance schedule and check official channels before the dates listed.
