ComEd default vs Alternative supplier on ComEd

What is comed default?

ComEd default is exactly what it sounds like: ComEd default supply rate. On a deregulated US supply market — Ohio, Pennsylvania, Texas, and a dozen others — this is one of the two shapes the supply line of your bill can take. The wires, the meter, the outage response, and the regulated delivery charges all stay with your utility regardless of which side you pick.

In comed default, the per-kWh rate is set by your utility, who passes through wholesale procurement results plus a small administrative margin. That has knock-on effects for budgeting, renewal cadence, and how exposed you are to the wholesale capacity auctions that drive winter price spikes in PJM territory and the August peaks in ERCOT. Buyers who care about predictability tend to weight comed default more heavily; buyers who actively trade the curve tend the other way.

Note that comed default is not a regulator-set product. It is a contract you sign with a licensed supplier (or stay on with your utility, depending on the kind). The PUC in your state publishes the supplier shelf and average rates; Seenra's job is to make the comparison effortless and to lock the term that fits your renewal calendar.

What is alternative supplier on comed?

Alternative supplier on ComEd works differently: Licensed retail electric supplier on ComEd lines. For most US households this is the default state — meaning if you have never opted into an alternative supplier, this is what is on your bill today. For commercial operators it is usually the starting point of a procurement audit, not the ending point.

The price formation under alternative supplier on comed is more dynamic. A licensed alternative supplier prices in the curve once at signing, then carries the procurement risk for the rest of the term. That dynamism is the feature for some buyers and the bug for others. If you have a fixed lease term, predictable hours, and a CFO who wants the supply line to look like a flat number on the rolling 12-month average, alternative supplier on comed introduces variance you may not want.

One thing that gets glossed over: switching between comed default and alternative supplier on comed is account-level, not infrastructure-level. There is no truck roll, no service interruption, no credit pull on the residential side. The first locked rate kicks in at your next utility meter read, typically 30 to 45 days after submission.

When comed default is the right call

• You have never audited the supply line and want a baseline to compare against.
• Your state has unstable supplier offers right now and the utility default is genuinely competitive this cycle.
• You are mid-contract on a different fixed-rate plan and waiting for renewal — utility default is your bridge.
• You are in a regulated state where alternative suppliers do not legally operate on the supply side.

When alternative supplier on comed is the right call

• You want predictability for the budget cycle, the lease term, or the multi-site portfolio.
• You have already done a supplier RFP and the alternative supplier rate beats utility default.
• You are renewing into a 24- or 36-month term to ride out a known volatile period.
• You operate in PJM or ERCOT and want capacity-period exposure removed from the supply line.

What stays the same either way

Regardless of which side you pick, the regulated half of your bill — wires, meter, capacity riders, taxes, the provider-of-last-resort fee — stays under your state PUC's tariff. Locking a supply rate does not lock the delivery line. We say so in plain English on every Seenra estimate.

Your outage call still goes to the same utility number. The truck that responds to a downed line is still your utility's truck. If you have a smart-meter dispute, that is still a utility-side conversation. Suppliers, on either side of this comparison, do not own physical infrastructure on US deregulated markets.
