EKS, 1990–1992 The team entered Naisten SM-sarja (now Naisten Liiga) in the 1990–91 season under the name Espoon Kiekkoseura or EKS. The two seasons played as EKS were an impressive showing for the newcomers and each resulted in a bronze medal, one in the 1990–91 season after defeating
Ässät and one in the 1991–92 season after defeating
KalPa. Several EKS players also played for the bronze medal-winning
Finnish women's national team at the
1992 IIHF World Championship including
Liisa Karikoski,
Katri-Helena Luomajoki, and
Hanna Teerijoki.
Kiekko-Espoo, 1992–1998 In 1992 EKS was renamed Kiekko-Espoo, the same name as its brother-team in the
Liiga. The team continued to be held to bronze or lower finishes, qualifying for five bronze medal series in six years and winning four of them (1993, 1994, 1997, 1998).
The Golden Age: Espoo Blues, 1998–2016 The team was renamed Espoo Blues in 1998, continuing the trend of sharing the name of its brother-team in the Liiga, which also renamed
Espoo Blues in that year. The name change unwittingly marked the beginning of a "golden age" for the team. Starting with their first SM-sarja gold medal in 1999, after achieving victory over
JYP Jyväskylä in the finals, they went on to win a staggering seven consecutive championships (1999–2005) and a total of thirteen championships in eighteen years. The Blues were kept off the SM-sarja medal podium only three times in the 1998–2016 span; in addition to their championship titles, they earned the team's first silver medal in 2009 and two more bronze medals in 2006 and 2016. The Espoo Blues were also strong competitors at international tournaments in this period, earning medals at six
IIHF European Women's Champions Cups: three silver medals (
2005,
2007-08,
2009-10) and three bronze medals (
2008-09,
2013–14,
2014–15).
Espoo United, 2016–17 In March 2016
Jääkiekko Espoo Oy, the parent club of both the Espoo Blues of the Naisten Liiga and Espoo Blues of the Liiga, declared bankruptcy with estimated liabilities of approximately €3 million. In response, Jussi Salonoja, a Finnish millionaire and film director who had previously owned the Espoo Blues franchise from 2002 to 2012, created a new club and organization called
Espoo United Oy, stating that he was "committed to supporting hockey in Espoo." The Espoo Blues men's and women's basketball and ice hockey teams would play for Espoo United. For the 2016–17 season the Espoo United women's ice hockey team played in the Naisten SM-sarja and won silver in the 2017 Finnish Championship. The
Espoo United men's team played in the
Mestis, the league below the premier-level Liiga, where they won bronze in the playoffs. On 15 August 2017 Salonoja announced that the Espoo United was abandoning its women's ice hockey and basketball teams for financial reasons. “The reason is twofold: the men's teams' budgets are far greater than those of women's teams, so their running is more demanding, but on the other hand, [the men's teams] are more interesting to sponsors and audiences,” Salonoja said. The future of women's ice hockey team was left uncertain and many possible solutions were proposed, including being acquired by HIFK or merging with Espoo Blues Juniorit (a junior club with strong ties to the franchise). == Season-by-season results ==
