Utah Power Credit Union has always maintained one of the highest dividend rates in the country. This, along with financially responsible members who trust their deposits with UPCU, has driven growth in assets. In fact, UPCU members' average savings balances are in the top 98% of all credit unions, nationwide. By the 24th Anniversary, the Credit Union reached $1,000,000 in assets. In 1983, 24 years later, the Credit Union was managing $12 million in assets. Another 24 years passed and assets approached $250 million by the end of 2007. Today, the Credit Union's asset size is approximately $950 million.

1989 marked the beginning of the power company as we know it today. Pacific Power and Utah Power came together to form PacifiCorp. Through the years since the merger the Credit Union opened its membership to include the employees of all PacifiCorp related entities.

UPCU began serving Pacific Power employees in the Wyoming region of PacifiCorp in 1992. Membership in Rock Springs quickly grew and by 2001 UPCU's Board of Directors approved the establishment of a branch office in Rock Springs. However, due to requirements, out-of-state chartered financial institutions are not allowed to independently operate branches in Wyoming. In 2005, PowerTrust Credit Union Service Organization was formed with Meridian Trust Federal Credit Union as a way of serving members in Wyoming. The PowerTrust Rock Springs office was opened in 2006 and an office in Casper was added in 2007.

The Credit Union's first ”branch office” opened, part-time, in a closet at the Interwest Mining office, in Huntington, Utah in 1988. The operation proved so successful that by 1999, the Credit Union built its first building. Today, the Huntington office accounts for about 20% of Credit Union loan volume.

While it is necessary for financial institutions to grow to remain viable, UPCU has never had a growth goal, and has never had designs on becoming ”one of the big guys.” When growth opportunities are reviewed, the Board and Management's analysis is based on one simple question, ”Will this opportunity benefit the members of Utah Power Credit Union?”

One of the ways credit unions grow is through mergers with other credit unions. UPCU has been approached many times over the years but only acted when it could be proven that a potential merger would benefit members, and that the merger would be in alignment with UPCU's core values. There have been four mergers in the Credit Union's 85+ year history: In 2000, UP&L Ogden Credit Union merged into UPCU. In 2008, Balance Rock Credit Union merged with UPCU. In 2012 and 2015, respectively, People's Electric Power Credit Union and Moon Lake Electric Employees Power Federal Credit Union merged into Utah Power Credit Union.

For 70 years, the Credit Union's official name was Utah Power & Light Employees' Credit Union. After much deliberation, the name was shortened to Utah Power Credit Union. The new name aligned more closely with the power company's name at the time. Also, removing ”employees” from the name signified that the Credit Union wasn't exclusively for employees—family members of employees were now included in membership eligibility.

The soul of the Credit Union still exists in the former main office, now branch office, of the Credit Union located at the North Temple Office (NTO) of Rocky Mountain Power. However, since 2010, the heart of Credit Union operations is found at the main office and branch in Murray, Utah. This building has allowed the Credit Union to continue to grow at a comfortable, and necessary pace. The branch provides convenient service to anyone in the Salt Lake Valley and the administrative operations support all 30,000+ Credit Union members.
