Tesla Megapack
Industrial-scale energy storage for facilities that need continuous power, predictable scale, and full operational control.
Where Megapack makes sense
Industrial sites
Peak shaving, backup for critical feeds, coupling with on-site generation, and lower energy spend through active load-profile management.
Solar and wind plants
Store surplus production, time-shift output, smooth delivery to the grid, and improve the market value of each kilowatt-hour.
Critical infrastructure
Hospitals, water, heat, transport - managed autonomy during outages and deliberate power reserves.
Grid and energy projects
Frequency regulation, load balancing, grid-forming, fast response, centralized control, and scaling from one unit to hundreds.
What Megapack delivers for your business
Use stored energy during peak tariffs to reduce maximum demand charges.
Earn from grid operator balancing signals and ancillary markets.
Protect critical loads from planned outages and grid faults.
Shift consumption to cheaper windows - e.g. night rates vs. daytime peaks.
Commercial services such as frequency and voltage support for the grid.
Full independence from the main grid when needed - islanded operation.
Megapack. An integrated infrastructure platform.
Integrated architecture
Modules, inverters, thermal management, and fire protection are assembled and factory-tested as a single product.
Energy efficiency
Round-trip efficiency up to 93.7% - fewer losses per cycle, higher yield per kilowatt-hour invested.
Software platform
Monitoring, mode optimization, and remote updates are one Tesla ecosystem - no third-party software stack.
Configurability
Eight archetypes - from utility scale to autonomous microgrids - for different electrical topologies and use cases.
Scaling
From one unit to hundreds of MWh - the same control architecture, software stack, and service model.
Safety
UL 9540A, built-in fire protection, and full factory testing of every unit before shipment.
The software ecosystem of Megapack.
Powerhub
A single interface to monitor and control storage, generation, and grid assets - industrial SCADA-style capability with minimal third-party systems.
Microgrid Controller
Coordinates battery, generation, and load as one on-site energy system - with automatic islanding when grid power is lost.
Autobidder
Automatically optimizes charge/discharge around tariffs, grid conditions, and operator business goals.
Updates throughout the lifecycle
Control algorithms update over the air - new capabilities, better optimization, and market adaptations from Tesla’s engineering team.
