Our publication of Naturgas press releases and their criticism of statements by Santiago Urdinola, VP of Mining, Hydrocarbons and Energy at business persons’ association ANDI has sparked a reply from the ANDI. It seems the statement about potential gas shortages in 2019 were in fact based on well-informed study, in particular scenarios developed by the UPME, a MinMinas research institute on energy issues. We publish in full their letter to us and finish with our commentary.
