Upload one usage file and we score your real last 12 months on both PECO rates — the one you're on now and the time-of-use one. You get the dollar answer, and exactly what you'd have to change to come out ahead.
Your answer uses one usage file and takes a few minutes. No file handy? The 60-second estimate needs nothing but a few questions. Either way, we never touch your rate, your bill, or your account.
on time-of-use than standard electric supply — same house, same 30-day usage, same appliances.
Actual observed 30-day interval usage priced using published PECO generation and transmission rates. Modeled comparison, not a bill guarantee.

Who it's closest to a no-brainer for
Time-of-use pays the most when you have big, flexible loads you can move — and when you have them all year, not just in summer.
An EV is the most shiftable load most homes have. Charging overnight instead of after work moves it straight into the cheapest window — close to automatic, 365 nights a year. Wattvia's estimator models roughly $210 a year from that one change alone.
No gas line means heat, hot water, and cooking all run on electricity — more total load, much of it flexible, and it doesn't take winters off. That's year-round opportunity, not a summer-only story.
Still worth a look. The four expensive weekday afternoon hours add up when the A/C runs hard — just expect the savings to lean seasonal rather than year-round.

What you get, free
One upload. No card, no utility connection, no commitment. Here's everything that comes back.
What your last 12 months would have cost on your current rate versus the time-of-use rate. Two numbers, plainly stated.
How much electricity your home actually uses on weekday afternoons between 2 and 6pm, and what it costs you.
The share of your power that always runs around the clock (your “always-on”) — fridge, wifi, standby. You'll never be asked to change it.
The specific routines worth shifting, and what each one is worth per year. Do them or don't; the file is yours either way.
The part people worry about
The most common question we get is some version of "what if I get this wrong?" Here's why you can't.
Wattvia can't change your rate, your plan, your bill, or your service. We read usage data and do math. Switching, if you ever do it, happens between you and PECO.
We recompute what you would have paid on each rate using your real usage. You always know where you'd stand, before deciding anything.
If your usage says stay where you are, that's what your assessment says. We're not a utility or a broker, and nobody pays us when you switch.
Before, and after
Knowing the number is half of it. The other half is whether your household can really keep those four hours quiet, week after week. The weekly score and badges do double duty: proof before you decide anything, and protection if you ever switch.
Every complete week, Wattvia scores your real usage and awards a badge when you hold the pattern. Hold them for a few weeks and you have your evidence: this household can do it. What you do with that is entirely your call.
Miss a week and nothing bad happens. You haven't proven it yet, and you haven't switched anything, so it costs you nothing to find out.
Every Monday you also get a scorecard — last week in dollars, what your timing earned, and what was left on the table. No app to open. It just arrives.
And if you do switch, the same weekly score is what stops a few off days from quietly costing you the savings you were counting on. The decision is always yours. We help you make it with real evidence — and if you take off, help you land it.
Your assessment costs nothing and doesn't need a card or a utility connection. If you want the weekly version — the Monday scorecard, the badges, the coaching — plans start at $29 a year.
Clear boundaries

Either way, you'll know in a few minutes, and it costs you nothing to find out. If the answer is no, keep the file, tell a neighbor who runs their dryer at midnight, and we're still friends.
