Tesla's energy storage deployments hit 13.7GWh in Q3 2026, their second-highest quarterly figure, yet revenues for the energy division fell 16% year-on-year due to tariff impacts and margin compression despite slight gross margin improvement aided by US tariff refunds.

This Wire brief sits within Fusion42's coverage of Climate Tech.

◆ ◆ The Wire takeaway

Tesla's energy storage revenue shrinkage amid strong deployment shows rising tariff costs are squeezing profits. You should factor tariff exposure into energy storage cost models and explore supply chain localisation options.
