Against the backdrop of the global energy transition, energy storage power stations in remote areas have become critical pillars of power supply. However, challenges such as high altitude, rugged terrain, volatile climates, and limited communications have consistently driven up operation and maintenance (O&M) costs. Drawing on project experience in over 95+ countries worldwide, ATESS combines intelligent O&M technology with localized service support to help clients reduce costs and improve efficiency across the entire project lifecycle.

Not all energy storage systems are built for the complexities of the Americas. Each country has its grid structure, voltage standards, and challenges, ranging from grid instability and aging infrastructure to frequent power shortages and solar-storage mismatches. In this white paper, we explore: Grid types and voltage standards across the Americas, key deployment challenges, and what to consider before choosing an ESS solution.

When designing energy storage systems, we often ask clients about the proportion of inductive loads in their system and use this information, combined with other basic system parameters, to determine the system configuration. So, what are inductive loads? In simple terms, they are motor-based loads. In industrial settings, these include loads like water pumps and hydraulic systems, while in commercial settings, they typically involve air conditioners, elevators, and similar equipment. A key characteristic of these loads is that during startup, the inrush current can reach 3–7 times the rated current, causing a significant spike in the system's instantaneous load demand. Even with soft-start devices like variable frequency drives, the startup current can still be 2–3 times the rated current.

Isla Grande in Colombia, a vibrant Caribbean island home to approximately 1000 Afro-Colombian descendants, has long sought a reliable and sustainable energy solution. This case study highlights the successful implementation of a cutting-edge hybrid solar-diesel power plant on Isla Grande, significantly improving the quality of life for its residents and fostering sustainable development. ATESS, a leading provider of advanced energy storage solutions, played a crucial role in this transformative project, deploying its PCS250 battery inverters,and battery storage system to enable an efficient and robust AC-coupled off-grid system. This innovative solution, seamlessly integrating with existing grid-tied inverters and diesel generators, ensures 24-hour electricity service for the first time, reduces reliance on fossil fuels, and lays the groundwork for future grid integration.
