Spanish power utility Endesa generated 8.5% more electricity in H1 2026 than in the same period last year, it said in its half-year earnings release.
Total power generated was 32.7 terawatt-hours, compared with 30.1 TWh in H1 2025, about one-third of which was sourced from renewables in both years.
Energy distributed rose to 72.6 TWh, up from 69.6 TWh in the year-ago period, while the number of end users was relatively stable at 12.76 million, compared with 12.72 million last year.
Net electricity sales slipped 2.3% to 35.4 TWh from 36.3 TWh in H1 2025, the earnings presentation said.
There was a notable drop in gas sales, which fell 17.6% to 25.6 TWh in H1 from 31.1 TWh a year ago, despite modest growth in end user numbers.
High availability of wind and solar power in H1 was the main driver of a 19.4% fall in wholesale electricity prices to 49.8 euros ($56.75) per megawatt hour.
Higher photovoltaic output during the period offset a 10% drop in hydroelectric power generation.
Endesa has a target of achieving net zero emissions by 2040. For the 2026-28 period, its strategic plan includes 5.5 billion euros investment in the grid to meet new demand, a 40% increase versus its previous two-year plan.
Investments in renewables generation will slow to 3 billion euros down from 3.7 billion in the prior two-year plan, it said.
