Tesla Motors launched its Tesla Energy brand with a line of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels.
With Tesla Energy, Tesla is amplifying its efforts to accelerate the move away from fossil fuels to a sustainable energy future with Tesla batteries, enabling homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience.
Tesla is already working with utilities and other renewable power partners around the world to deploy storage on the grid to improve resiliency and cleanliness of the grid as a whole.
Tesla is not just an automotive company, it’s an energy innovation company. Tesla Energy is a critical step in this mission to enable zero emission power generation.
Powerwall Home Battery
The Tesla Powerwall is a rechargeable lithium-ion battery designed to store energy at a residential level for load shifting, backup power and self-consumption of solar power generation.
The Powerwall consists of Tesla’s lithium-ion battery pack, liquid thermal control system and software that receives dispatch commands from a solar inverter. The unit mounts seamlessly on a wall and is integrated with the local grid to harness excess power and give customers the flexibility to draw energy from their own reserve.
The battery can provide a number of different benefits to the customer including:
– Load shifting – The battery can provide financial savings to its owner by charging during low rate periods when demand for electricity is lower and discharging during more expensive rate periods when electricity demand is higher
– Increasing self-consumption of solar power generation – The battery can store surplus solar energy not used at the time it is generated and use that energy later when the sun is not shining
– Back-up power – Assures power in the event of an outage
The Powerwall Home Battery increases the capacity for a household’s solar consumption, while also offering backup functionality during grid outages.
The Powerwall is available in 10kWh, optimized for backup applications or 7kWh optimized for daily use applications. Both can be connected with solar or grid and both can provide backup power. The 10kWh Powerwall is optimized to provide backup when the grid goes down, providing power for your home when you need it most. When paired with solar power, the 7kWh Powerwall can be used in daily cycling to extend the environmental and cost benefits of solar into the night when sunlight is unavailable.
Tesla’s selling price to installers is $3500 for 10kWh and $3000 for 7kWh. (Price excludes inverter and installation.) Deliveries begin in late Summer.

Tesla Energy for Businesses
Based on the powertrain architecture and components of Tesla electric vehicles, Tesla energy storage systems deliver broad application compatibility and streamlined installation by integrating batteries, power electronics, thermal management and controls into a turn key system.
Tesla’s energy storage allows businesses to capture the full potential of their facility’s solar arrays by storing excess generation for later use and delivering solar power at all times. Business Storage anticipates and discharges stored power during a facility’s times of highest usage, reducing the demand charge component of the energy energy bills.
Energy storage for business is designed to:
– Maximize consumption of on-site clean power
– Avoid peak demand charges
– Buy electricity when it’s cheapest
– Get paid by utility or intermediate service providers for participating in grid services
– Back up critical business operations in the event of a power outage
Tesla Energy for Utility applications
For utility scale systems, 100kWh battery blocks are grouped to scale from 500kWh to 10MWh+. These systems are capable of 2hr or 4hr continuous net discharge power using grid tied bi-directional inverters.
Systems support applications including peak shaving, load shifting and demand response for commercial customers while offering, renewable firming and a variety of grid services at utility scales.
Tesla Utility Storage is designed to:
– Firm up renewable generation by reconciling the intermittency of power from these sources and storing excess capacity to dispatch when it’s needed.
– Increase resource capacity. Utility Storage acts as on-demand distributed power generation, contributing to the overall generating capacity while adding resiliency to the grid.
– Ramp Control. Utility Storage can act as a buffer while the power output from a large generation source is ramping up or down, delivering power instantly to smoothly transition output to the required level.
– Improve power quality by preventing fluctuations from propagating to downstream loads.
– Defer costly and time-consuming infrastructure upgrades.
– Manage peak demand by deploying power within seconds or milliseconds.
