GEMS has become the most-used energy storage software and integration platform, operating in over 70 systems in nine countries. The GEMS software platform is used for voltage and frequency regulation, peak shaving, PV smoothing, microgrids, and back-up power for critical loads. Greensmith leverages advanced hardware, intelligent optimisation, and operational expertise backed by Wärtsilä's reputation as a bankable and reliable partner.
Cyborg Score Rationale
Greensmith demonstrates strong market positioning with significant deployed capacity, industry-leading software adoption, and backing from a major multinational corporation. However, as a subsidiary of Wärtsilä (acquired in July 2017), independent growth metrics are limited and competitive pressure from cloud-native and AI-driven energy storage software providers is increasing.
