From the most affordable Tesla Model 3 all the way up to the supercar-crushing Model S Plaid, every Tesla mixes technology, speed, driving range, and the peace of mind of a vast charging infrastructure in a way that nobody else has been able to match. The Supercharger network is faster than most and able to add 200 miles of range to a Model S Plaid in just 15 minutes. Musk knows the network's value and that's clear based on one of his latest tweets.

Late in June, Tesla was said to have confirmed that it would open up its Supercharger network to other automakers and their electric vehicles by September 2022 but Musk has just confirmed this will happen before the end of the year. While this is great news for EV owners, the upshot for Tesla is the expected massive boost to its revenue.

According to Teslarati, research from the investment bank Goldman Sachs estimates that Tesla could make over $25 billion in revenue per annum once its Supercharger network opens up to other brands. The bank's research included the number of Level 3 Superchargers that Tesla has. The numbers are impressive, with around 3,000 stations and approximately 25,000 stalls. There are also the company's Level 2 Destination Chargers to consider.

"Tesla opening up its network could represent a sizable opportunity over time as the EV fleet grows, especially if Tesla charges more for non-Tesla owners," said the bank in an excerpt from its research.

However, the investment bank's figure of $25 billion is based on Tesla increasing its base of Superchargers from 25,000 to 500,000. Of course, it will also depend on the use of these charges and the price charged, variables which are unknown at this point. Currently, an annual revenue opportunity of $1 billion exists with the current size of the charging network.

While 500,000 sounds like a big number, EV sales keep increasing and these consumers will want access to as many charging stations as possible. Recently, Volkswagen said that 80 percent of ID.4 buyers are trading in their gas-powered cars for the electric crossover.

Musk didn't say which countries will benefit from the open Supercharger network first - hopefully, the US is high on the list, but we also expect European regions like Norway to be a priority. Until that happens, owners of other EVs have had to use third-party charging networks like Electrify America, which aims to have 800 charging stations installed in the US by the end of the year. However, Musk's latest move could dramatically impact third-party charging networks like Electrify America. The extent of that will be revealed in the months to come.
