Home vs public DC fast charging
Home charging is the default cost optimization. Public DC fast charging in Wyoming runs about 3.4× the home rate. For 12,000 miles/yr entirely on DC fast, annual fuel cost would be $2006 vs $589 at home — a $1417 penalty. Apartment dwellers and road-trippers should price this in; daily commuters with home Level 2 can usually ignore public chargers.
DC fast rate is a network average (Electrify America + EVgo + Tesla Supercharger + ChargePoint). Real prices vary by location, time of day, and membership tier.
EV incentives in Wyoming
Wyoming does not currently run a state-level EV purchase rebate. Federal Section 30D credit of $7,500 still applies for qualifying vehicles (US-assembled with sourced battery components, MSRP cap, household income cap). Check the EV tax credit eligibility list for your vehicle. Some utilities offer charger installation rebates — check with your local utility.
