APS Still Funds a Pension for Nearly Everyone. Your Hire Date Decides Which One.
Arizona's biggest electric utility runs a fully funded, company-paid pension with two very different designs, split at 2003. Add the Fidelity Savings Plan and strongly funded retiree medical, and APS careers still end in the kind of retirement most of corporate America retired. I help APS and Pinnacle West employees figure out which tier they hold and what it changes.

The Pinnacle West Retirement Plan is noncontributory (APS pays, you don't) and covers nearly all employees. Per the company's 10-K it stood at roughly 99% funded on a GAAP basis at the end of 2024, 100% on an ERISA basis, with zero expected contributions through 2027 and a liability-driven investment strategy behind it. Funding strength like that is the quiet good news; the planning work lives in which tier you hold:
| Tier | Who holds it | What it means at retirement |
|---|---|---|
| Traditional formula | Generally pre-2003 hires who did not switch when the account balance option was offered in April 2003 | A monthly annuity computed from pay and service. Retirement timing and the survivor option you elect drive its value; the election is irrevocable. |
| Account balance (cash balance) | Hires from 2003 on, plus switchers | A notional account growing with pay and interest credits, typically payable as a lump sum you can roll to an IRA. Portable, visible, and it moves the investment decision to you after payout. |
One honesty note: Pinnacle West does not publish the account balance plan's pay credit and interest credit schedule in its filings, so precise projections come from your own plan estimate. Bring it, and the modeling gets specific fast, including the lump-sum-versus-annuity comparison where both options exist.
The Savings Plan, Retiree Medical, and What the Pension Frees Up
The Savings Plan
The Pinnacle West Savings Plan runs on Fidelity with pre-tax and Roth options and a company match. Third-party sources put the match at 75% of your first 6%, but the company does not publish the formula, so treat that as a starting point and confirm your current match, and whether after-tax contributions are available, in your own plan documents.
With the pension covering an income floor, your Savings Plan can usually afford to work harder than a pension-less peer's, and the years between retirement and required distributions are prime territory for Roth conversions worth modeling in advance.
Retiree Medical and the Officer Layer
Pinnacle West's retiree medical program reported funding near 195% on a GAAP basis, with a post-65 health reimbursement arrangement in the design. A funded healthcare bridge changes early-retirement math more than almost any other benefit; confirm your eligibility tier and price the bridge years before you pick a date.
Officers and designated highly compensated employees also have a supplemental excess benefit arrangement above the qualified-plan limits; if that is you, its distribution timing belongs in the same plan as everything else.
APS and Pinnacle West employ roughly 6,400 people, with headquarters in downtown Phoenix and major operations across the Valley, and no employee stock purchase plan (the Investors Advantage Plan you may have seen is a public dividend reinvestment program, not an employee benefit). If your household also touches SRP, the SRP benefits stack has its own page.
Plan terms referenced on this page are current as of July 2026; confirm the specifics with your benefits administrator.
