Integrating Battery Energy Storage Systems (BESS) into Data Centers: Technical, Economic, and Market Analysis

Abstract

The rise of Artificial Intelligence, the growing need for cloud computing, and the expansion of e-commerce and crypto mining are driving a boom in the data center industry, placing increasing pressure on power infrastructure. At the same time, new data center deployment is often constrained by limited grid capacity, interconnection delays, and regulatory barriers. This study evaluates how Battery Energy Storage Systems (BESS) can address these constraints and enable more flexible and reliable data center power systems. The strengths, weaknesses, and overall viability of BESS are contextualized in four unique use cases: Economics and Pricing, Load Flexibility, Power Quality, and Backup Power. The value of BESS is further assessed across different data center types, forming a primary layer of the decision-making framework for data center developers. The trade-offs of BESS adoption are analyzed across different market conditions, and key implementation challenges are also discussed, including cost, space constraints, and permitting complexity.
