Commissioning of Pampa Energía’s fifth wind farm

Buenos Aires, June 16, 2023. Pampa Energía S.A. (‘Pampa’ or the ‘Company’; NYSE: PAM; ByMA: PAMP) informs that the last wind turbines of the Pampa Energía Wind Farm IV (‘PEPE IV’), located in Coronel Rosales, Province of Buenos Aires, will be commissioned by CAMMESA as of 0 hours of tomorrow. Hence, the 18 wind turbines at PEPE IV will contribute to the national grid with 81 MW of renewable energy. The construction of PEPE IV required an investment of over US$128 million. The energy produced by the wind farm will be sold through B2B PPAs to industrial customers in the Renewable Energy Market (Mercado a Término de Energía Eléctrica de Fuentes Renovables, MAT ER).

Gustavo Mariani, CEO of Pampa Energía, commented on this achievement, stating, ‘This wind farm exemplifies Pampa’s commitment to helping Argentina achieve the goals set by Law 27,191, which mandates that 20% of the national power grid be supplied from renewable sources by 2025’. He further added, ‘In addition to this accomplishment, we are currently building phases 1 and 2 of our sixth wind farm, which will have installed capacities of 95 MW and 45 MW, respectively. The total investment for these projects is estimated to be approximately US$265 million’.

Pampa Energía is one of the country’s largest power generators, with a total capacity of 5,432 MW. Since 2018 including the expansion projects in the pipeline, we have invested more than US$1 billion in renewable energy. By the second semester of 2024, with the completion of PEPE VI, we will have reached a total installed capacity of 527 MW, further strengthening Pampa’s position as one of the leading wind power generators in the country.
