Iberdrola already has excellent relationships with several sports organisations and competitions, including the Spanish Billie Jean King Cup team, the Spanish Olympic and Paralympic Committees, and the Spanish women's national football team. In total, it supports 32 national federations in Spain and is associated with the Spanish player Paula Badosa, who will be playing in the finals in April 2022 and is ranked number 2 in the WTA.

The company is committed to gender equality, in line with the ITF's Advantage All strategy. Iberdrola thus joins a growing list of Billie Jean King Cup sponsors and partners who share similar values, including title partner Gainbridge, global partners Microsoft and Magellan, and apparel partner Tory Burch.

ITF President David Haggerty was delighted with the agreement. "We are pleased to welcome Iberdrola as the Official Energy Partner of the Billie Jean King Cup by Gainbridge. We were impressed by their commitment to supporting women and girls in sport, something that the ITF also strives to achieve through our Advantage All programme. We are grateful to Iberdrola for their investment in our competition, which will allow us to continue to raise the profile of the Billie Jean King Cup around the world", he commented.

Laura Gil, Sports Sponsorship Manager at Iberdrola, echoed these sentiments. "At Iberdrola, we are already proud sponsors of the Spanish women's national tennis team, and now we are adding the sponsorship of the Billie Jean King Finals, which promises to be an incredible spectacle at the La Cartuja Stadium in Seville. We have been committed to supporting women in sport since 2016, and this is a journey we will continue to build on," she emphasised.

Founded in 1963 as the Federation Cup and known as the Fed Cup since 1995, the Billie Jean King Cup was renamed three years ago in honour of the legendary Billie Jean King. In addition to her lifelong advocacy for recognition and equality in women's sports, Billie Jean King remains the competition's most decorated individual with a total of 10 titles as both a player and captain of the United States team.

Switzerland will be defending its title in the third edition of the final in this new format. A total of 12 countries will take part, divided into four groups, with only the group winners guaranteed a place in the semi-finals.

The Swiss team has been placed in a challenging Group A, alongside the United States and the Czech Republic. Group B includes the reigning runner-up, Australia, along with Kazakhstan and Slovenia. Group C features the host country, Spain, competing against Canada and Poland, while Group D includes France, Italy, and Germany.

Notable absentees from the top 5 of the WTA rankings (Belarus' Aryna Sabalenka, Poland's Iga Swiatek, American Coco Gauff, Kazakh Elena Rybakina, and American Jessica Pegula) leave Czech player Marketa Vondrousova (6th) as the highest-ranked participant. Among the top 20 are another Czech, Barbora Krejcikova (10th), Switzelland's Belinda Bencic (14th), and France's Caroline Garcia (20th).

The competition kicks off on Tuesday 7 November at La Cartuja with Switzerland taking on the Czech Republic and Australia on Slovenia. On Wednesday, the other two groups will make their debut, with Spain facing Canada and France taking on Italy.
