after that, Hidroeléctrica Española and Iberduero merged to form Iberdrola. In the latter part of the 20th century, Iberdrola began expanding into Latin America, mainly Mexico and Brazil. With ScottishPower and Iberdrola formed in Europe, in 1998 Energy East Corporation came into being in the US following New York State Electric & Gas's acquisition of Central Maine Power, Southern Connecticut Gas Company, Connecticut Natural Gas Company, Berkshire Gas Company and RGS Energy Group (the parent of Rochester Gas & Electric). Following the arrival of Jose Ignacio Sanchez Galan in 2001 Iberdrola began focusing on renewable energy. In 2007, the company continued its international expansion, increasing its presence in the UK and the US via the integration of ScottishPower and Energy East. Iberdrola has faced several merger attempts and made additional acquisitions: Attempted merger between Iberdrola and Repsol in 1997, which failed due to a lack of agreement between the companies. Attempted merger between Iberdrola and Repsol in 1999, which was rejected by La Caixa (Repsol's main shareholder). Attempted merger between Iberdrola and Endesa in 2000, which was stopped due to the conditions imposed by Spanish Prime Minister José María Aznar. Attempted hostile takeover bid by Gas Natural for Iberdrola in 2003, which was vetoed by Spain's National Energy Commission (Comisión Nacional de Energía, CNE). Acquisition of ScottishPower by Iberdrola in November 2006, which led to the integration of this company in April 2007. This gave rise to Europe's third largest utility. Acquisition of US company Energy East by Iberdrola in 2008. Acquisition of Brazilian company Elektro in 2011. Acquisition of US company United Illuminating in 2015. Acquisition of Australian company Infigen Energy (which included the largest Wind Farm worldwide, the 1000 MW Mount James wind farm) in 2020.
