Development of New Wind Farms

Buenos Aires, January 30, 2018. Pampa Energía S.A. (‘Pampa‘ or the ‘Company‘; NYSE: PAM; BCBA: PAMP) announces the commencement of construction of two new wind farms in the Province of Buenos Aires, which will aggregate an installed capacity of 100 MW and will demand an estimated investment of US$140 million.

These projects will be developed under the new regulation framework for the Term Market from Renewable Energy Sources (‘MAT ER‘), issued by the Ministry of Energy and Mining through Resolution No. 281/17, and by which the Wholesale Electricity Market Company (‘CAMMESA‘) granted the dispatch priority for wind farm projects named ‘Pampa Energía‘ and ‘De la Bahía‘, targeted at the market of Large Users by selling power provision agreements between private parties.

The priority allocation of 28 MW for ‘De la Bahía‘ and 50 MW for ‘Pampa Energía‘ will ensure dispatch for both wind farms and therefore, will guarantee the provision to our clients who have chosen to comply with their obligation of fulfilling electricity demand with renewable sources of energy coming from our wind farms.

The Pampa Energía wind farm will be placed nearby Corti wind farm, with an installed capacity of 100 MW, which is located 20 kilometers (12 miles) from the City of Bahía Blanca and will be commissioned in May of this year. Moreover, the De la Bahía wind farm will be built in the Coronel Rosales area, 25 kilometers (16 miles) from Bahía Blanca.

It is worth highlighting the wind quality of both projects‘ area, which fosters a load factor higher than 50%. Moreover, it is scheduled the installation of 15 wind turbines in each farm.

The new capacity of 100 MW to be developed, in addition to the Corti wind farm which is currently under construction, add up as of today 200 MW of renewable sources‘ power capacity developed by Pampa. Therefore, once all expansion projects are commissioned, the total installed capacity that Pampa Energía will contribute to the Argentine grid will amount to 4.4 GW.
