The network hasn’t been cheap to build and maintain, but with revenue from other automakers and their customers, it was also making ever-bigger piles of money. Along with its home-battery business, where profits were up 140% year-on-year, charging has been a rare area of growth for the company. Morgan Stanley’s Adam Jonas, one of the top Tesla analysts, last year estimated the value of the charging business at $100 billion.
Tesla doesn’t disclose its Supercharger earnings numbers, but recent estimates by Bloomberg NEF say the company generated around $1.74 billion of charging revenue last year, roughly 1.5% of total revenue. By 2030, Bloomberg estimates that Tesla could make $7.4 billion per year, or around 6% of the global charging business.
