150 Amp Service Upgrade
Quick answer
A 150-amp service upgrade costs $1,400–$3,000, a middle step that fits some homes, though most upgrades justify going straight to 200 amps. We quote both so you can compare.Typical installed cost: $1,400–$3,000
150 amps exists as a legitimate middle tier: more than a 100A service, cheaper than some 200A jobs when the existing service entrance supports it. We'll tell you when it genuinely fits, and when the small price difference to 200A makes the bigger panel the obvious choice.
About 150 Amp Service Upgrade
150 amps is the middle child of service sizes, and sometimes exactly right. If your meter base and service entrance already support 150A, the upgrade can skip the expensive entrance work a 200A job would trigger, delivering a meaningful capacity bump at a friendlier price.
We're candid about the math: when the 200A path costs only a little more, it's the better buy. When your infrastructure makes 150A notably cheaper and your loads fit, it's a smart, code-compliant sweet spot.
The 150A fit test
- Existing service entrance rated for 150A (no rebuild needed)
- Moderate loads: one EV with load management fits; two don't
- Gas appliances keeping electric demand in check
The honest math between 150 and 200 amps
Here's the comparison worth making before you decide. If your existing service entrance and meter base are rated for 150A, the upgrade avoids their replacement, often saving $500–$1,200 versus a 200A job that rebuilds them. If those components need replacement anyway, the incremental cost of 200A shrinks toward the price of the panel itself, and the bigger service wins on value.
The load side matters equally: one EV with load management fits 150A comfortably in most homes; two EVs, or an EV plus full electrification, points to 200A. We quote both paths with real numbers so the decision is arithmetic, not persuasion.

When your service entrance and meter already support it, your loads are moderate, and the 200A option would trigger expensive service-entrance work. Otherwise 200A usually wins on value.
Often yes, 150A with load management supports a Level 2 charger in most homes. The load calculation confirms it.
Many quote only 200A because it's simpler to standardize. We size to your home, the load calculation and your service entrance decide, not a one-size default.
