What TUCSON ELECTRIC POWER puts in, and what the plan costs
What TUCSON ELECTRIC POWER put into the plan, per active participant
$4,583
TUCSON ELECTRIC POWER CO put $4,583 into this plan for each of its 2,079 active participants in plan year 2024. This is the whole employer side of the plan: matching money, profit sharing, non-elective and safe-harbor contributions, and reallocated forfeitures. The Form 5500 does not separate them, so this is what the employer put in and not the match.
TUCSON ELECTRIC POWER put in less per active participant than 70% of plans with 1,000–4,999 participants at utilities. The middle plan in that group of 80 reported $6,417. Utilities comes from business code 221500, which TUCSON ELECTRIC POWER entered on its own Form 5500. Sponsors pick that code themselves, so a code that does not describe what the employer does ranks the plan against the wrong companies.
What this figure cannot separate: how much TUCSON ELECTRIC POWER pays, and how much it puts in
This is dollars, not a rate. A Form 5500 carries no payroll, so the figure reflects both how much the employer puts in and how much the employer pays: two plans running the same formula report different amounts when one pays better. Crossing the peer group with industry holds most of that difference still, and none of it disappears.
This is one plan year, not an average. A true-up, a plan merger or a one-off contribution moves a single year on its own.

The $4,583 above is the Form 5500 figure for plan year 2024, and it counts every employer dollar on one line. TUCSON ELECTRIC POWER CO also files a Form 11-K, which states the match formula for plan year 2025: the card below reads $2,228 a year at a $49,500 salary, and the same filing states employer contributions made outside the match. That second figure is what the formula pays one worker on that salary, and not an amount either filing reports. The two figures cover different plan years and measure different things, so neither one is the other one corrected.
What TUCSON ELECTRIC POWER puts in
$2,228
a year, at a $49,500 salary.
The filing discloses only part of the formula. The most it states the employer adds is 4.5% of pay, for a worker contributing 4.5% of pay.
The match paragraph, word for word
“The Company may, at its discretion, make matching contributions to each participant’s account in an amount equal to a percentage of the participant’s compensation as defined by the Plan for that payroll period subject to certain limitations, including the amount contributed to the Plan. For the Plan year ended December 31, 2025, the Company made matching contributions to all unclassified employees of 100% of employee deferrals up to 4.5% of eligible compensation and per applicable collective bargaining agreements for classified employees. For the Plan year ended December 31, 2024, the Company made matching contributions: (i) to Tucson Electric Power Company unclassified employees of 100% of employee deferrals up to 4.5% of eligible compensation; (ii) to UNS Gas, Inc. and UNS Electric, Inc. unclassified employees of 50% of employee deferrals up to 6% of eligible compensation; and (iii) per applicable collective bargaining agreements for classified employees. In 2025, the Plan was amended to require the Company to make non-elective employer contributions for newly hired or rehired employees, excluding student interns, equal to 6% of the eligible participant's compensation and to allow the Company to make discretionary matching contributions of 100% of employee deferrals up to 4.5% of eligible compensation. This amendment was effective January 1, 2025, for unclassified and certain classified employees and June 1, 2025, for certain additional classified employees.”

Vesting score
100 out of 100
How fast the employer’s money becomes yours. Higher than 48% of the 369 schedules we have scored.
It measures vesting speed and nothing else. It says nothing about the size of the match, what the plan charges, or the funds inside it.
Share of the employer's money that is the worker's at hire and at each of the first 6 anniversaries: 100%, 100%, 100%, 100%, 100%, 100%, 100%. The score is the average of those 7 readings.
Vesting, word for word
“Participants are 100% vested immediately in their contributions and the Company's matching and non-elective contributions, plus actual earnings thereon.”
The wait before the match starts and the year-end true-up appear above when the filing states them. Neither is part of the score, and a filing that is silent on one of them is not a plan without it.
What the plan costs, against plans of its size
71st percentile
$120.61 per participant in plan-paid administrative cost, more expensive than 71% of plans with 1,000–4,999 participants.
