French renewables company Voltalia increased its operational solar portfolio to 2,006MW by the end of the first half of 2026, accounting for the majority of its total operational capacity of 2,962MW, which grew 17% year-over-year.
Total capacity in operation and under construction reached 3,564MW, up 9%, while the company revised its 2026 operational target to around 3.6GW from approximately 3.7GW, citing a selective review of construction phasing while maintaining its financial objectives.

Voltalia generated 2,408GWh of electricity during the first half of 2026, an increase of 1% year-on-year, with second-quarter production rising 4% to 1,303GWh. Growth was supported by newly commissioned projects, particularly in South Africa and Uzbekistan, together with continued expansion of its subsidiary Helexia’s portfolio.
From a financial perspective, first-half energy sales revenue reached €190.2 million (US$216 million), while the second-quarter energy sales revenue totalled €118.2 million.
Solar load and curtailment trends
Across its solar portfolio, Brazil remained the company’s largest market with 791MW of installed solar capacity. Solar load factors in Brazil remained stable at 24%, while the solar load factor excluding curtailment declined slightly to 28% from 29% a year earlier.
Elsewhere, France recorded a solar load factor of 14%, up from 13%, while Portugal improved to 20% from 19%. Solar load factors fell to 25% in Jordan and Egypt from 27%, remained stable at 22% in Albania and declined to 17% in the UK from 19%.
Curtailment continued to be a key operational issue in Brazil, although volumes improved during the period. Production curtailment fell to 218GWh during the first half from 268GWh a year earlier, representing 13% of Brazilian production and 8% of the Group’s total production. During the second quarter, curtailment decreased 42% year-on-year to 105GWh, accounting for 14% of Brazilian production.
The reduction in curtailment volumes was accompanied by the implementation of Brazil’s compensation mechanism covering wind and solar production losses between September 2023 and November 2025. Voltalia said the associated regulatory uncertainties had now been resolved following clarification from the Ministry of Mines and Energy and industry associations.
Solar pipeline and future capacity growth
Alongside its operating portfolio, the company advanced new solar development in French Guiana, securing €165 million in financing for the Saint Anne hybrid power plant. The project will combine a 43MW PV solar power plant, 135MWh of battery energy storage and a 7MW biofuel generator.
By 2030, the firm is targeting around 5GW of capacity in operation and under construction, including around 4.5GW in operation. Voltalia also aims to have 50% of its solar capacity in operation located on dual-use or enhanced land by 2027, alongside a 35% reduction in the carbon intensity of its owned solar power plants by 2030.
