Smart Meter Overcharging: How to Check if Your PG&E Meter Is Wrong

Your bill jumped $200 last month. Nothing changed — same appliances, same habits, same number of people in the house. PG&E's explanation: "usage increase." You know that's wrong.

There's a real possibility the problem isn't your usage. It's your meter.

Smart meters fail, malfunction, and report incorrect readings more often than PG&E admits. Over 20% of Reddit threads in PG&E-focused communities mention suspected meter issues as the root cause of unexplained bill spikes. One Northern California homeowner disputed a meter reading and received $2,500 in bill credits after PG&E confirmed a malfunctioning meter and issued a swap.

Here's exactly how to figure out if your smart meter is lying to you — and what to do about it.

Signs Your Smart Meter May Be Overcharging You

Smart meter errors don't always announce themselves. Look for these patterns:

1. Sudden spike with no usage change The clearest signal: your bill jumps 30–50%+ month-over-month, but nothing changed in your home. You didn't add an appliance, didn't host guests, didn't run AC more. If PG&E's usage graph shows a sharp cliff upward, that's worth investigating.

2. Usage spikes at odd hours Check your hourly usage data in your PG&E account (My Energy → Energy Use). If you see high consumption at 2 AM or during hours you were away, something is wrong. Either a device is running you don't know about — or the meter is registering phantom usage.

3. Bills inconsistent with your appliances A typical 1,500 sq ft California home with central AC uses roughly 600–800 kWh/month in summer. If your meter shows 1,400+ kWh with the same setup, it's worth a second look.

4. Meter readings that don't match your own This is the definitive test. Read it yourself (instructions below).

How to Read Your Own Smart Meter

PG&E smart meters (mostly Itron OpenWay Riva or Landis+Gyr) cycle through several display screens. Here's how to read yours:

  1. Locate your meter — usually on the exterior of your home, often on the side or back wall
  2. Press the button on the meter face to cycle through displays
  3. Find the kWh reading — look for a screen labeled "01" or "kWh" with a 5-digit number (e.g., 08462)
  4. Record readings 24–48 hours apart — note the date and time for each
  5. Calculate your daily usage: subtract the first reading from the second

Then compare to what PG&E reports in your online account under My Energy → Energy Use. The numbers should match (or come very close — within a few kWh). If PG&E's reported usage is significantly higher than what you measured, you have documented evidence of a discrepancy.

Pro tip: Take a photo of the meter display each time you read it. This documentation is critical if you file a dispute.

Real Example: $2,500 Back After a Meter Swap

A homeowner in Concord, CA noticed their bill had roughly doubled over three months. Usage graphs showed no clear cause — no unusual spikes, just a steady elevated baseline. After reading their own meter and comparing it to PG&E's records, they found a consistent 30–40% discrepancy.

They filed a meter accuracy complaint through PG&E's customer service and escalated to CPUC (California Public Utilities Commission) when PG&E's initial response was unsatisfactory. PG&E dispatched a technician who confirmed the meter was over-registering. The meter was replaced and PG&E retroactively recalculated 90 days of billing at corrected rates — resulting in $2,500 in bill credits.

The key: they had photos, dates, and their own meter readings documented before they called.

How to File a Meter Dispute with PG&E

Step 1: Call PG&E directly 1-800-743-5000. Request a "meter accuracy test" or "meter re-read." PG&E is required to investigate. This is free — you're entitled to one free meter test per 12-month period.

Step 2: Document everything Before you call, gather:

Step 3: Escalate to CPUC if needed If PG&E dismisses your complaint or delays unreasonably, file a formal complaint with the California Public Utilities Commission:

CPUC complaints carry real weight. PG&E is required to respond within a set timeframe and provide documented justification for their billing. Many disputes that go unresolved at PG&E level get resolved quickly after CPUC involvement.

Step 4: Request retroactive billing correction If a meter error is confirmed, explicitly request retroactive correction — not just a meter replacement. PG&E is required to recalculate your bills using estimated correct usage for the affected period. Don't settle for only fixing the meter going forward.

Bottom Line

Smart meters malfunction. PG&E won't audit your account on your behalf. If your bill spiked and nothing changed, the burden of proof falls on you — but the process to dispute it is straightforward if you document carefully.

Read your meter. Compare it to PG&E's records. Call 1-800-743-5000 and request a meter accuracy test. Escalate to CPUC if needed. And keep photos of everything.
