Endesa has announced a €17 million investment to reinforce and modernise Ibiza's electricity distribution network after a summer marked by repeated power outages across the island.

The investment programme will run from 2027 to 2030 and includes 77 separate actions across all five municipalities, covering almost 68 kilometres of distribution network.

The announcement follows months of complaints from residents, businesses and institutions over repeated interruptions to the electricity supply during the peak summer period.

77 Projects Across Ibiza

The planned works will focus mainly on the medium-voltage network, with the aim of increasing capacity, improving reliability and making the system more resilient during periods of exceptionally high demand.

The investment is distributed across the island.

Santa Eulària will receive the largest allocation, with more than €5.4 million for 16 projects covering around 20.1 kilometres of network.

Sant Josep follows with more than €4.8 million across 21 projects and nearly 17 kilometres.

Sant Antoni will receive more than €3 million for 14 projects covering 11.7 kilometres, while Sant Joan has four projects worth more than €1.7 million covering 11.1 kilometres.

In Ibiza Town, 22 projects will receive around €1.9 million, covering almost eight kilometres of network.

A Response to a Difficult Summer

The announcement comes after a summer in which power cuts became a recurring problem in different parts of Ibiza.

Several incidents affected homes and businesses, with some outages lasting for hours.

The Consell had previously demanded greater investment and warned that the situation could not be repeated, particularly because interruptions were affecting businesses during the busiest period of the tourism season.

The latest plan is therefore intended to address both the immediate weaknesses identified during the summer and the island's longer-term growth in electricity demand.

Endesa Blames Exceptional Heat and Demand

According to Endesa, this summer's incidents occurred in an exceptional context of sustained high temperatures combined with very high electricity consumption.

Heavy use of air conditioning and other cooling equipment increased demand across the network, while prolonged heat placed additional thermal stress on infrastructure.

The company says this combination contributed to the activation of protection systems and failures at certain points in the network.

The explanation has been questioned by some local representatives, who argue that the island's infrastructure must be sufficiently robust to cope with predictable peaks in summer demand.

Most Works Planned Before Next Summer

The timing of the investment will be closely watched.

The Consell has called for the majority of the works to be completed before the 2027 summer season, while Endesa has stressed the need for close coordination with the municipalities so that permits and construction can progress as quickly as possible.

Working groups will be established with the island's town halls to coordinate the specific locations and execution of the projects.

A Further Low-Voltage Plan Is Coming

The €17 million programme does not cover everything.

Endesa is also preparing a complementary plan for the low-voltage network, which will be added to the projects already announced.

That second stage could be particularly relevant for local streets and neighbourhoods where problems are concentrated closer to individual consumers rather than on the main distribution infrastructure.

No complete figure or final list of projects for that additional programme has yet been announced.

Maintenance Will Also Be Under Scrutiny

The Consell has made clear that investment in infrastructure should be accompanied by stronger preventive maintenance.

President Vicent Marí has requested sufficient staffing, contracts and technical resources to identify potential failures before they happen and to respond more quickly when incidents occur.

The request comes after a summer in which repeated outages affected both residents and businesses across the island.

Ibiza's Energy Challenge

The €17 million investment represents a significant upgrade for Ibiza's electricity network, but it also highlights a broader challenge facing the island.

Electricity demand has increased alongside population, tourism and the widespread use of air conditioning during increasingly hot summers.

The new programme is designed to give the network greater capacity and resilience, while the additional low-voltage plan and stronger maintenance requirements are expected to address further weaknesses.

After a summer of repeated blackouts, the focus now turns to how quickly the promised works can be delivered.

For Ibiza, the real test will come when the next high-season heat arrives and the island's electricity network is once again operating at its busiest.
