AES Fonseca was originally proposed in 2005 as a 220 MW plant; by 2008, cost projections had doubled to US$600 million due to rising steel prices, but AES had obtained financing, and construction was expected to begin in early 2009.[1] As of mid-2009, construction had been placed on hold pending the outcome of an international tender in which AES was slated to compete with other bidders for energy contracts.[2]

A year later, AES announced that it would fuel the plant with natural gas rather than coal[3], but the project remained stalled due to unfavorable economic conditions in El Salvador.[4]

In April 2011, La Unión mayor Osmar Cruz signed a new municipal ordinance prohibiting coal-, oil- and natural gas-fired power plants, further jeopardizing the plant's prospects.[5] As a result of this ordinance, AES Fonseca opted not to participate in El Salvador's March 2012 energy tender.[6]

In August 2012, new mayor Ezekiel Milla reconfirmed the town's prohibition of coal-fired plants, but reversed the previous ban on natural gas plants.[7]
