We’ve all been affected by the energy crisis in South Africa, and while load shedding appears to be a uniquely South African issue, energy consumption and storage is a global concern.
The world currently consumes 20 trillion kWh of energy annually.
Enough energy to power a single family home for 1.8 billion years or supply energy to a nuclear power plant for 2,300 years (or launch the Falcon 9 rocket seventeen million times).
Of all the fossil fuel consumed in the United States, one third is used in transportation and another third goes to electricity production. The US electric power sector alone produces over 2,000 million metric tons of CO2 which is like burning 225 billion gallons of gas. The EPA says it would require 1.6 billion acres of US forest to negate the environmental damage.
What if we could move the electricity grid off of fossil fuels and towards renewable energy sources?
Once we’re able to rely on renewable energy sources for our power consumption, the top 50% of the dirtiest power generation resources could retire early. We would have a cleaner, smaller, and more resilient energy grid.
Today, Tesla introduces Tesla Energy, a suite of batteries for homes, businesses, and utilities fostering a clean energy ecosystem and helping wean the world off fossil fuels.
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.
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.
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.
