Practical Tips to Cut Costs
Charge at night during off-peak hours. Set your Tesla app to start at 10 PM. This drops rates to $0.18/kWh and saves 20%. Install a Level 2 charger like the Tesla Wall Connector for $500 to $800. It charges twice as fast as a standard outlet and qualifies for a $500 federal tax credit.
Track your habits. Most drivers average 12,000 miles yearly (33 miles daily). Use Sidekick's fuel calculator for your zip code. It pulls real-time Eversource rates and your driving data to show exact costs.
Compare to gas. A similar sedan at $3.50/gallon costs $6 to $8 daily for 40 miles (30 mpg). You save $1,000+ yearly with home charging (Source: EIA Fuel Cost Report, 2026).
