200 Amp Service Upgrade: Why Your Home Needs More Power | Bright Haven Electric

Why Your 100-Amp Panel Can’t Handle the Future
The year 1978 called. It wants its fuse box back. Here is why the shift to electric vehicles and heat pumps makes a “Heavy Up” essential for modern Minnesota homes.
If you live in a home built before 2000 in Milan or Appleton, there’s a good chance your electrical panel is maxed out. Back then, homes were designed for a 120-volt lighting load and perhaps a single electric dryer. Today, the shift to carbon-neutral living—driven by EVs, heat pumps, and induction ranges—is overwhelming these legacy systems.
The Signs Your Panel is Struggling
You don’t need to be an electrician to spot a panel that’s over its head. These are the red flags:
The “A/C Dim”
Do kitchen lights flicker when the AC or fridge kicks on? That’s a severe voltage drop caused by a system running near capacity.
Warm Breakers
Put your hand on the plastic cover of your breakers. They should be cool. Heat means resistance, and resistance is a fire starter.
No Room to Grow
Old “split-bus” panels often lack physical slots for the modern AFCI/GFCI breakers required by code for new circuits.
100A vs. 200A: The Modern Standard
Think of electricity like water flowing through a pipe. A 200 Amp Service Upgrade isn’t just a bigger pipe—it’s a complete infrastructure overhaul.
The Old Way (100A)
Designed for gas appliances and minimal electronics. Often limited to ~19.2kW continuous load.
- Gas Range & Water Heater
- Standard 120V Outlets
- No EV Charging Capacity
The New Standard (200A)
Ready for electrification. Supports ~48kW peak, handling heavy simultaneous loads with ease.
- Level 2 EV Charger (11kW+)
- Electric Heat Pump & Backup
- Induction Stove & Hot Tub
Financial Architecture: Grants & Rebates (2026)

The “Power Control System” (PCS) Option
Under 2026 NEC (Article 120), if a physical service upgrade is impossible (e.g., restricted underground access), we can install a smart PCS. This device monitors total energy use and dynamically “throttles” non-essential loads (like potential EV charging) to prevent main breaker trips, avoiding expensive trenching.
