Comparative Evaluation of Standards and Economic Analysis in the Implementation of Large-Scale BESS Systems

Abstract

The increasing penetration of intermittent renewable energy sources, such as solar and wind, has created a need for efficient energy storage systems, such as Battery Energy Storage Systems (BESS). This paper provides a comparative evaluation of the most relevant international standards, such as IEEE 1547, NFPA 855, UL 9540, and IEC 60287, and their impact on the design and implementation of large-scale BESS systems. Additionally, an economic analysis is conducted regarding the costs associated with the installation of underground versus overhead systems, evaluating aspects such as durability, energy efficiency, and safety. Through an extensive review of literature and existing case studies, the paper offers a detailed insight into best practices and operational challenges in integrating BESS into modern electrical grids. The results indicate that while underground installation presents higher initial costs, it offers advantages in terms of safety and longevity, whereas overhead systems may be more cost-effective in environments with lower environmental risks. This analysis provides key recommendations for optimizing the deployment of BESS systems in urban and rural infrastructures.
