When left-wing, pro-renewables politician Andrés Manuel López Obrador became president last December, it was assumed that the successful green-energy tenders, which had resulted in 7GW being contracted over the past three years, would continue.

Yet within weeks of AMLO’s inauguration, a scheduled tender to contract 19.8TWh a year over 15 years was cancelled. Then, earlier this month, Manuel Bartlett, the all-powerful boss of the federal power company CFE, which buys all the power from the country’s energy tenders, said renewables were too expensive and that there would be no more tenders.
