Iberdrola has a workforce of around 31,330 employees in dozens of countries on four continents serving around 31.67 million customers. Subsidiaries include Scottish Power (Scotland), Iberdrola USA (United States) and Elektro (Brazil), amongst others. The largest shareholder of the company was, in 2013, Qatar Investment Holding; other significant shareholders are ACS, Kutxabank and Bankia.[2]

Since embarking on its growth and international expansion plan in 2001, Iberdrola has become Spain’s largest energy group by market capitalisation,[3] the global leader in wind energy[4] and one of the world’s largest utilities by market capitalisation.

Iberdrola was created on November 1, 1992 as a result of the merge between Hidroeléctrica Española and Iberduero.[6] Hidroeléctrica Española, also known as Hidrola had started activity in 1907, while Iberduero started in 1944 as the result of the merge between Hidroeléctrica Ibérica (1901) and Saltos del Duero.

The origin of Iberdrola lie in the Spanish industrialisation in the early 20th century, when Hidroeléctrica Ibérica was formed. As of 2011 and with the integration of Scottish Power and Energy East, now renamed Iberdrola USA, the company has become a major multinational group.

In 1840, a group of American entrepreneurs created the Hartford City Light Company, setting in motion the incorporation on the eastern seaboard of the US of Energy East, which would much later become Iberdrola USA. Meanwhile, thousands of kilometres away in Spain, a similar process was underway. In 1901 in Bilbao, a group of entrepreneurs headed by engineer Juan de Urrutia established Hidroeléctrica Ibérica. In 1907, Hidroeléctrica Ibérica shareholders created Hidroeléctrica Española to supply Madrid and Valencia. A decade later, Saltos del Duero was founded, opening the country’s first hydroelectric facility in 1935, the Ricobayo power plant.

World War I forced the industry to seek new sources of energy and to install large distribution networks. Amid huge instability, US power companies began to join forces, attempting to become strong enough to withstand the economic and financial uncertainty. However, no one foresaw the magnitude of the stock market crash of 1929, which brought these emerging groups to the verge of ruin. In Spain, which had experienced a period of economic growth at the start of the 20th century, the industry suffered a severe setback in 1936 whose impact would be felt for the following two decades: the Civil War abruptly halted development, destroyed facilities and made maintaining the little equipment that remained extremely difficult.

Spain suffered international isolation in the 1940s and experienced extreme difficulty in acquiring technology and materials, prices of which were soaring. It was against this backdrop that Hidroeléctrica Ibérica and Saltos del Duero joined forces to form Iberduero.

In 1955, the South of Scotland Electricity Board (SSEB) came into being, paving the way for the creation of Scottish Power four decades later, in 1990. Two years after that, Hidroeléctrica Española and Iberduero[4] teamed up, creating 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 Scottish Power[7] and Energy East.[8] 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 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 Scottish Power 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.[9]
  • Acquisition of Brazilian company Elektro in 2011.

Iberdrola manages its production assets, comprising hydroelectric, combined-cycle gas, nuclear and co-generation plants located in 40 countries, mainly in Europe, North America and Latin America. Output in Spain: 58,076 GWh in 2013, of which 14,795 GWh were produced at hydroelectric plants. As a result, 79% of Iberdrola’s production in Spain was CO2 emission free.

It has offices located in its principal distribution centres in the two states. In New York, the business is shared by two operating subsidiaries – New York State Electric & Gas (NYSEG) and Rochester Gas and Electric (RG&E)– both headquartered in Rochester. In Maine, Central Maine Power (CMP) has headquarters in Augusta. NYSEG serves 878,000 electricity customers and 261,000 natural gas customers across more than 40% of upstate New York, whereas RG&E serves 367,000 electricity customers and 303,000 natural gas customers in nine counties around the city of Rochester.[10] CMP is the largest energy supplier in Maine, serving over 600,000 customers.

Iberdrola USA promotes important infrastructure projects in both Maine and New York. In Maine, CMP began construction in September 2010 of the Maine Power Reliability Program (MPRP),[11] a $1.4 billion upgrade of the state’s transmission network which will also improve grid connections to Canada. It also began the roll-out of a smart meter installation plan for 625,000 customers in Maine. In New York, important infrastructure projects have been undertaken at Ithaca and Corning Valley.

Headquartered in Valencia (Paseo de la Alameda), the Iberdrola Renovables subsidiary had been listed on the stock exchange until July 2011, when Iberdrola decided to integrate it into the parent company. At the end of 2013, Iberdrola had operating installed capacity above 14,247 MW -53% outside Spain- producing a total of 33,899 million kWh of power in the year.

Major assets

  • Renewable Energy Operations Centres - CORE (Toledo, Portland and Glasgow)

Iberdrola's Renewable Energy Operations Centres (CORE for their initials in Spanish) in Toledo, Portland and Glasgow are the world's most important renewables facilities and pioneers in the industry for their cutting-edge technology.These centres control all Iberdrola's renewables facilities and their related substations worldwide 24/7, 365 days a year. Iberdrola's first CORE was set up in Toledo in 2003, with the other two coming on stream since.

With initial installed capacity of 322 MW, it is currently being enlarged to 539 MW. The complex is situated south of Glasgow and covers an area of 55 square kilometres, the same as that occupied by Glasgow itself. It boasts the first renewables learning centre in the UK, enabling a large number of people to find out more about the various renewable energy sources.[14] Whitelee has obtained the prestigious Queen’s Award for its commitment to sustainability. The award recognises excellence in habitat management and the promotion of local community involvement in the renewable energies project.

  • The El Andévalo wind farm (Huelva, Spain)

The El Andévalo wind farm, which was commissioned in 2010, is the largest wind power facility in Spain and continental Europe. It has installed capacity of 292 MW and is located between the towns of El Almendro, Alosno, San Silvestre and Puebla de Guzmán in the south of Huelva province. To transfer the power generated by these wind farms and connect them to the transmission grid, Iberdrola has built a new 120-kilometre line between Spain and Portugal, which means this complex occupies a key strategic position in the power interconnections between the two countries.[15]

The Peñascal wind farm[16] is the largest facility operated by the company worldwide, with installed capacity of 404 MW. Located in Kenedy County, Texas, its innovative features include a radar that detects the arrival of large flocks of migratory birds and shuts down the turbines if visibility conditions represent a danger.
