Analyst Insight: Energy Storage Systems Case Studies

Energy storage systems (ESS) are fundamental to creating a smarter, more flexible energy system and will be a crucial enabler in the energy transition. Globally, countries are recognizing the benefits provided by these technologies, including grid balancing, frequency regulation, and integration of renewable energy sources (RES). To date, ESS deployment has focused on select markets. The US, China, and several European countries, among others, are home to significant storage capacity, installed in preparation for the continued proliferation of RES as these nations look to diversify power generation.

With robust policies and significant investments in grid infrastructure modernization, developed countries are pioneering large-scale ESS projects. Further, as the storage duration of ESS projects increases, long-duration energy storage technologies are emerging on a commercial scale. These advances are crucial for managing the increasing penetration of intermittent RES and ensuring a stable energy supply amid growing climate concerns and regulatory pressures.

Using data from Guidehouse Insights’ Energy Storage Systems Tracker 2Q24, this Analyst Insight provides information on currently tracked projects by region and storage type, assesses market drivers and barriers, highlights two noteworthy case studies in Europe, presents a market overview for North America, and provides key recommendations for industry stakeholders.
