Getting set up to charge a 2026 Rivian R1S Dual Large (22in) at home
The numbers above assume Level 2 home charging is already in place — the electrical work behind that is a real, separate cost that varies by panel, wiring, and local labor rates, not something this page's per-mile math includes.
Ask a licensed Alaska electrician to quote the install before this math becomes a real decision.
