Documented cause
Greensmith Energy, a Rockville, Maryland-based battery energy storage software company, built an energy storage management platform that integrated with multiple hardware vendors. Despite deploying 150+ MWh of storage projects with utilities including Con Edison and AES, the company was unable to build a standalone software revenue base — revenue remained project-tied. Wartsila acquired Greensmith in April 2017 for an undisclosed amount estimated below $50M, absorbing it to gain grid software capabilities.
Lesson
“Battery software must decouple from hardware project revenue early to command standalone SaaS multiples.”
