Can Tesla Be an Energy Company? If the Battery Is Good Enough…
The scale of Tesla’s battery production, even for its own use as an auto manufacturer, thrusts the company into ‘key player’ status for grid storage. There are currently around 15 Lithium Ion battery deployments with >1MW of capacity in the US with the largest installation being 40MW. Tesla’s current Model S production (assuming 80 units per day with an 80kWh average battery capacity – ie. 80% of Model S’s delivered with 85 kWh packs, 20% with the 60kWh) is equivalent to 6.4 MW hours of battery capacity per day. At that rate, by our calculations Tesla’s Model S production could produce a combined vehicle population with as many MW of battery storage for the US grid as exists today (304 MW) including all chemistries in just 6 weeks.

- 1 Tesla Model S (85 kWh) can store enough energy to power the average US household for 3.5 days.
- By 2020, we estimate Tesla’s 690k unit US fleet will contain the stored energy capacity to provide 1 full hour of electricity to 1.6% of US households.
- By 2028, we estimate Tesla’s 3.9m unit US fleet will contain the stored energy capacity to provide 1 hour of electricity to 8% of US households.
- By 2028, we estimate Tesla’s 7.2m unit global fleet will contain the stored energy capacity of 443 GW, an amount exceeding the entire daily electricity consumption of Mexico, or more than 50% than the Kingdom of Spain.
