PG&E PanelBoost (SPAN Edge): skip the panel upgrade in California
How PG&E's PanelBoost and SPAN Edge load-management option can let California homes add EV charging, batteries, and appliances without a costly panel upgrade.
Quick answer
PG&E's PanelBoost program uses a smart load-management device (SPAN Edge) installed at the meter so a California home can add EV charging, a battery, a heat pump, or other electric loads without a full main panel upgrade. It is not free — installation is commonly estimated around $500 to $2,000 — but it can avoid a service upgrade that often costs several thousand to tens of thousands of dollars. PG&E has indicated more program details and a sign-up path arriving in 2026, so confirm current availability before planning around it.
What PanelBoost / SPAN Edge does
A traditional panel upgrade raises your home's electrical capacity by replacing the service panel. PanelBoost takes a different approach: a device at the meter manages and balances loads in real time, so the home can run new high-draw equipment without exceeding the existing panel's safe capacity. For many homes that means the same end goal — EV charging or electrification — without the cost and permitting timeline of a full MPU.
When this is the better path
- You want to add EV charging, a battery, or a heat pump but were quoted an expensive panel upgrade.
- Your panel is adequate for daily use but lacks headroom for one or two big new loads.
- You want to avoid the multi-week permitting and utility-coordination timeline a service upgrade can require.
- You are weighing solar plus storage and want to control upfront electrical costs.
When you may still need a full upgrade
- Your existing panel is old, unsafe, or already at capacity.
- You are adding several large loads at once that exceed what load management can balance.
- An electrician or inspector flags the panel itself as a safety issue.
How to evaluate it
- Get a panel-upgrade quote first so you know the number you are comparing against.
- Ask whether a load-management device (SPAN Edge / PanelBoost) can meet your goal instead.
- Confirm current PG&E program details, eligibility, and any installer requirements.
- Compare total cost, timeline, and what each option supports long term.
Common mistakes
- Assuming PanelBoost is free — it has an installation cost, just usually far below a full MPU.
- Choosing it when the existing panel is genuinely unsafe and should be replaced.
- Planning around it before confirming the program is open in your area.
