Ford Fathom Can Cut the Cost of EV Home Power. Here's Why This Changes Everything.  

What's new: Ford will offer AC bidirectional power on the all-new Fathom electric lifestyle truck in 2027. It will be the first EV from a U.S. automaker with an MSRP below $30,000 that does not need a separate wall-mounted inverter to supply more than 10 kW of AC power to a home.

Why It Matters: 

• Bidirectional power lets an EV send energy back to a home or the grid. It turns the vehicle into mobile energy storage. 
• Cost has held the technology back. Exchanging power between a DC battery and an AC home has required expensive external hardware like an inverter. The price tag limited it to premium vehicles and early adopters.  
• Fathom customers can get two benefits:  
  • Lower bills: Home Power Management lets customers charge when electricity is cheaper and power the home when it's pricier. The Ford Home Power Station is the only hardware needed.
  • Backup power: Home Backup Power runs the home during an outage. It's a clean, quiet alternative to natural gas or diesel generators. Customers need the Home Power Station and Ford Home Backup Power Panel. 

The Big Picture:  

• Utilities face rising energy demand from energy-intensive technologies and more frequent extreme weather. Bidirectional EVs could help them meet demand and keep service reliable, including through virtual power plants. 
• Interconnection rules, the process required to connect a new power source to the grid, haven't kept up. They were written for fixed assets such as rooftop solar and stationary batteries, and EVs are vehicles first. 
• In July 2026, Ford formed a utility working group to help define scalable processes before Fathom launches. Members are American Electric Power, BC Hydro, Consumers Energy, Exelon, and Pacific Gas and Electric Co. 
• The group agreed on three principles:   
  • Recognize differences: Require interconnection only when a bidirectional EV operates in parallel with the grid. It shouldn't apply to charging-only use or isolated backup power. 
  • Anticipate change: Update procedures and regulations to reflect the latest standards for both DC and AC systems. 
  • Solve together: Utilities, regulators, and automakers should work jointly to make interconnection easy. 

By The Numbers: 

• Under $30,000: Fathom's price class, the first for AC bidirectional power from a major U.S. automaker 
• About 50%: How much less the Home Power Station costs than Ford’s first-generation bidirectional charger
• At least 60%: How much less the Home Backup Power Panel costs than the prior-generation home backup hardware  
• 3,000+: Utilities across the U.S. and Canada, with largely unique interconnection processes 
• 10kW+: The amount of power that can be sent to the home or grid
   

How It Works: 

1. Built-in hardware: After acquiring Auto Motive Power in 2023, Ford designed the Universal EV Platform's bidirectional hardware and software from a clean sheet. It uses fewer multifunctional parts and puts the inverter inside the vehicle's E-box, one of the five main modules.  
2. Less external gear: The inverter capability onboard the vehicle replaces a costly wall-mounted inverter, which cuts system complexity and cost. 
3. Safe grid connection: The system is designed to meet UL 1741 requirements and comply with IEEE 1547 interconnection standards. 
4. Lower-cost communication: It uses the existing SAE J3068 standard (with LIN-CP), which also reduces the Home Power Station's cost. 
5. Customer setup: Customers add the Home Power Station for bill savings. For backup power, they add the Home Backup Power Panel too.
