Iberdrola USA, which became part of the group in September 2008, distributes electricity and gas to 2.44 million customers in the states of Maine and New York. 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. 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), 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. 


In 2015 Iberdrola USA merged with UIL Holdings (parent of Connecticut's United Illuminating and other companies) to become Iberdrola-controlled Avangrid.






Iberdrola also owns hydroelectric plants, especially in the Duero river basin (provided by Iberduero) and the Tajo and Segura river basins, etc. (provided by Hidroeléctrica Española). 

Construction is finished on the 848 MW La Muela plant (at Cortes de Pallás, Valencia) and on the 175 MW San Esteban II plan, on the Sil river. The San Pedro II project has started its construction.






Headquartered in Valencia (Paseo de la Alameda), the Iberdrola Renovables subsidiary had been listed on the stock exchange from December 2007 until July 2011, when Iberdrola decided to re-acquire the minority shares and 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.

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.


The Whitelee Wind Farm (Glasgow, Scotland) 

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. 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.

Peñascal Wind Power Project (Texas, USA)

The Peñascal wind farm 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.
