Guidehouse Insights Names Fluence, Tesla, RES, Powin Energy, and Nidec ASI the Leading Utility-Scale Energy Storage Systems Integrators

Integrators have become the key position in the value chain for ensuring energy storage projects are successfully built and profitable

BOULDER, Colo.–(BUSINESS WIRE)–#EnergyStorage–A new Leaderboard report from Guidehouse Insights examines the strategy and execution of 13 utility-scale energy storage systems integrators (UESSIs), with Fluence, Tesla, RES, Powin Energy, and Nidec ASI ranked as the leading market players.

With cumulative UES deployment revenue projected to exceed $188 billion by 2029, the market represents a significant opportunity. Driven largely by the increasing use of solar and wind generation, interest is mounting in energy storage to maintain grid stability and increase efficiency by allowing nonessential fossil fuel power plants to close. As the market matures, the role of UESSIs has become the key position in the value chain for ensuring that projects are successfully built and that they become profitable. Click to tweet: According to a new Leaderboard report from @WeAreGHInsights, Fluence, Tesla, RES, Powin Energy, and Nidec ASI are the leading UESSIs.

“These companies are actively pushing the boundaries of how energy storage is viewed by stakeholders in the industry, and they are working to open new markets,” says Ricardo F. Rodriguez, research analyst with Guidehouse Insights. “The industry remains highly competitive, with companies offering similar products and services, and behind the leaders are several other companies well-positioned to capitalize on new markets and project opportunities.”

According to the report, since 2018, UESSI companies have shifted their focus from turnkey project development (including systems integration) to a more pure-play systems integrator and operator role. Although many leaders still offer turnkey project development as it might be preferred by some customers, the overall market is trending toward specialized systems integrators being hired by project developers. This transition has occurred as systems integrators have become better at optimizing the value of energy storage across multiple revenue streams for different customers using sophisticated software and controls.

The report, Guidehouse Insights Leaderboard: Utility-Scale Energy Storage Systems Integrators, evaluates the strategy and execution of 13 UESSIs. Using Guidehouse Insights’ proprietary Leaderboard methodology, vendors are profiled, rated, and ranked to provide industry participants with an objective assessment of these companies’ relative strengths and weaknesses in the global market for UES integration. 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. An executive summary of the report is available for free download on the Guidehouse Insights website.
