Whether you started at SCE&G decades ago or joined after the Dominion merger, your retirement benefits — and your Medicare handoff — depend on paperwork most people haven't looked at in years.

---

If you work for Dominion Energy South Carolina — at the Cayce campus, V.C. Summer, the Saluda hydro station, or out on the lines anywhere in the Midlands — there's a decent chance your career didn't start with Dominion at all. It started with SCE&G or SCANA, and your benefits carry that history with you. SCANA's pension covered regular full-time employees hired before January 1, 2014, and the company provided postretirement health and life benefits to certain employees — benefits that transferred into Dominion's hands with the 2019 merger, along with a round of early-retirement buyouts that reshaped who's still there.

All of which means one thing for anyone approaching 65: your benefits depend on your hire date and your paperwork, not on what the person at the next desk remembers. Here's how to line up your Medicare transition either way.

Still on the job at 65

Dominion is well past the 20-employee threshold, so the group plan stays primary while you're actively working, and you can delay Part B penalty-free until you leave. Most employees take premium-free Part A at 65 — unless you're contributing to an HSA, in which case any Medicare enrollment ends your contributions. Utility pay plus decades of service also means many Dominion retirees have income high enough to trigger IRMAA — Medicare's income-based premium surcharge, calculated from your tax return two years back. A retirement year with a big payout (unused vacation, incentive pay, a lump-sum pension election) can inflate your Medicare premiums two years later. If your income drops at retirement, you can appeal IRMAA using Social Security's life-changing-event form — most people don't know that.

The retirement clock

The rules are the same ones every large-employer retiree faces, and they're strict:

• 8 months to enroll in Part B after active coverage ends, or a lifetime penalty applies.
• COBRA doesn't pause that clock, and it pays second to Medicare once you're 65 whether you enrolled or not. Don't bridge with COBRA past your window.
• 6 months after your Part B starts to buy any South Carolina Medigap plan with no health questions. For a lineman or plant worker with a few decades of wear and tear on record, that no-underwriting window matters.

The SCANA-legacy questions to pin down

Before you set a retirement date, get answers in writing from the benefits center on:

1. Do you have retiree medical, and what happens to it at 65? Legacy postretirement health benefits often change form when Medicare becomes primary — some convert to a subsidy or an HRA that reimburses you for a plan you buy yourself. The rules about which plans qualify, and how you must enroll to unlock the money, are the whole ballgame.
2. Pension elections and timing. Pre-2014 hires with the defined-benefit pension face lump-sum vs. annuity decisions that interact with taxes — and, through IRMAA, with your Medicare premiums. Sequence matters.
3. Retiree life insurance. Legacy plans often included postretirement life benefits, but amounts frequently reduce with age. If your family counts on that coverage, know the schedule before you rely on it.
4. Your spouse's coverage. If they're under 65 and on your plan, your retirement date is their coverage cliff too.

Where we come in

• We read your retirement packet and any SCANA-legacy documents with you and turn them into a plain-English picture of what you actually have.
• We build your calendar — Part B application, Medigap guaranteed-issue window, Part D start date — so everything begins the day your group coverage ends.
• We run the whole South Carolina market. As independents we compare Plan G, Plan N, Medicare Advantage, and drug plans across carriers — including checking whether any legacy retiree benefit beats replacing it, and whether your HRA (if you have one) restricts your choices.
• We watch the IRMAA angle and flag when a retirement-year income spike is about to cost you on premiums — and when you have grounds to appeal.
• No cost, no obligation. Carriers pay us the same regardless of which plan you pick.

The bottom line

Dominion retirees in the Midlands are navigating two layers at once: federal Medicare timing rules that forgive nothing, and a benefits file that may span two company names and three decades. Both layers are manageable — if you start before your last day, not after. Bring us the packet, even if retirement is still a year or two out. We're in Lexington, the review is free, and you'll leave knowing your dates and what that SCANA-era fine print actually means for you.
