Tesla Energy

Tesla Energy operates a hardware-plus-recurring-services model: customers purchase or lease energy-storage hardware (Megapack for utilities, Powerwall for homeowners and small businesses) and then pay for ongoing software, monitoring, and grid-service enrollment. The core product is physical — Megapack is a factory-built, containerized lithium-ion battery system sold to utilities, independent power producers, and large commercial sites. Powerwall is a smaller residential unit sold through installers and direct to consumers. Revenue is recognized upon delivery and installation of the hardware. On top of that, Tesla offers software platforms (Autobidder, a real-time trading and control platform for utility assets) and virtual-power-plant programs that pool Powerwall and Megapack capacity to sell grid services — these generate ongoing recurring fees or revenue-sharing with asset owners. Hardware carries typical manufacturing margins, with scale advantages from Tesla's battery-cell supply chain and vertical integration through its own Megapack factory. The recurring software and grid-services layer adds higher-margin, subscription-like revenue that scales with the installed base. The capital-intensive hardware component means cash flow is lumpy and driven by project timelines, while the service layer provides a growing annuity as more assets come online.
