Tesla Megapack: This Large Battery Costs $1.2 Million

The commercial site of Tesla in the United States now offers the purchase of Megapack, a massive battery pack whose price is staggering.

First of all, let’s answer the question: what is a Tesla Megapack? It is a high-capacity, technologically advanced energy storage solution designed to meet the needs of utilities, grid balancing, and large-scale renewable energy projects (such as solar or wind power). It plays a key role in the transition toward more sustainable energy sources and stabilizing electrical grids.

The Megapacks use advanced battery technology to provide high energy density, meaning they can store more energy in a smaller space compared to other energy storage solutions. Tesla has also developed custom energy management software to optimize storage and consumption. Finally, they are designed to be easily installed and quickly commissioned. They come pre-assembled, reducing installation time and cost. However, as we will see, the cost is not insignificant…

The Megapack will be available from the first quarter of 2024 at a price of $1,227,090 excluding taxes, or about 1.12 million euros. For this price, the customer benefits from 979 kW of power* and 3.9 MWh of energy** over a 4-hour period. For a version twice as powerful (1927 kW) but with half the autonomy, the cost is $1,278,860 (1.16 million euros).

Installation costs are not included. For this, add an additional $638,280 (582,700 euros)! Finally, the annual maintenance package is $8,830 (8,060 euros), with a contractual inflation rate of 2% per year. For the “2-hour” version, installation costs are even higher: $802,200 (732,300 euros)! Connecting to the electrical grid is expensive…

One more detail: you will need a solid concrete pad under the Megapack. Its weight is approximately 38.1 tonnes (84,000 pounds).

Glossary

* Power (measured in watts, W):

• The power of a battery indicates how quickly it can deliver or absorb energy. It’s similar to the flow rate of water from a tap.
• Measured in watts (W), power indicates how much energy can be delivered at any given moment.
• A high-power battery can supply a large amount of energy in a short time, which is crucial for applications requiring high power peaks, such as engine starting or rapid charging of a device.

** Energy (measured in watt-hours, Wh):

• The energy of a battery refers to the total amount of electricity it can store and supply over time. It’s comparable to the capacity of a water tank.
• It is often expressed in watt-hours (Wh) or kilowatt-hours (kWh). The higher a battery’s energy capacity, the longer it can power an appliance.
• For example, a 1000 Wh battery can provide 100 watts for 10 hours or 10 watts for 100 hours.
