Navigant Research Leaderboard Report: Utility-Scale Energy Storage Systems Integrators

Assessment of Strategy and Execution for
14 Energy Storage Systems Integrators

As the energy storage industry continues developing, the role of the systems integrator is becoming more and more important. Integrators are responsible for maximizing the value of a system by enabling all available revenue streams to be captured, ensuring constant availability, and maximizing system life. Energy storage systems (ESSs) will increasingly be asked to serve different applications—ranging from short-duration and high-power ancillary services to long-duration time shifting of energy. Systems integrators are responsible for managing this complexity by designing systems that can provide the maximum value to both the grid and the system owners.


An emerging trend in the utility-scale energy storage systems integration (ESSI) space is the growing diversity of the backgrounds of leading players. This study covers companies with backgrounds in renewable project development, utility ownership, electrical grid equipment and services, battery manufacturing, civil and electrical engineering services, and innovative energy management systems. Systems integrators emerging as Leaders have leveraged their backgrounds to provide a range of flexible solutions that include full turnkey project development. Such a model allows for a more open approach to meeting the needs of various customers and is expected to allow a company’s business to scale rapidly.

This Navigant Research Leaderboard Report compares the strategy and execution of 14 leading energy storage systems integrators (ESSIs) focused specifically on the utility-scale market. These companies are rated on 12 criteria: vision; go-to-market strategy; partners; production strategy; technology; geographic reach; sales, marketing, and distribution; product performance; product quality and reliability; product portfolio; pricing; and staying power. Using Navigant Research’s proprietary Leaderboard methodology, vendors are profiled, rated, and ranked with the goal of providing industry participants with an objective assessment of these companies’ relative strengths and weaknesses in the global utility-scale ESSI market.
