Sunrun Makes Fortune 1000 Debut: America's Largest Home Battery Storage and Solar Provider Joins the Ranks of the US's Top Revenue-Generating Companies
San Francisco – Sunrun has been named to the Fortune 1000 list for the first time, entering the annual ranking of the 1,000 largest US companies by revenue. The leading provider of home battery storage and solar energy is, according to the company, the only business of its kind on the list.
Sunrun CEO Mary Powell commented: "Being named to the Fortune 1000 shows the strength of our subscription model and the trust we've earned from the more than 1.1 million customers who have chosen Sunrun to power their homes."
Sunrun pioneered the energy-as-a-subscription model in 2007 and has since grown into America's largest distributed power plant operator. The company currently operates 18 distributed power plant programs across multiple states. The more than 1,300 coordinated dispatch events in 2025 – delivering a total of 18 gigawatt-hours – highlight the growing importance of distributed home storage as an active contributor to grid stability: by feeding stored energy back into the grid on demand, networked home batteries help bridge supply gaps and prevent blackouts. Sunrun earns recurring revenues from grid operators and utilities for providing this service.
Sunrun's growth trajectory has continued into 2026: first quarter total revenues rose to $722 million, up 43 percent from the same period last year. The storage attachment rate reached a record 73 percent, with total installed networked storage capacity of approximately 4.3 gigawatt-hours.
However, the company's share price has not benefited from the positive news. Listed in the renewable energy stock index RENIXX World, Sunrun's shares declined 10.8 percent to €12.74, placing the company last in the RENIXX ranking after the first four trading days of this week.
