1. The O&M of utility-scale solar projects involves cleaning panels, monitoring inverters, maintaining grounds, and checking tracker mechanisms.
2. Large-scale BESS installations require different maintenance activities such as replacing faulty modules, racks, inverters, and balance of system components.
3. Power Factors uses data-driven products to optimize BESS project portfolios, focusing on acquiring and analyzing data to foresee system failures and improve O&M strategies.
Asset managers play a crucial role in optimizing the performance of large-scale lithium battery energy storage system (BESS) installations. These systems generate a vast amount of data that needs to be monitored to ensure the batteries are functioning at peak capacity. Power Factors, a large-scale asset manager, offers a data-driven product called Unity Performance Management to assist BESS project owners and operators in their O&M tasks, increasing uptime and yield.
For BESS maintenance, activities fall into two categories: corrective maintenance, which involves replacing faulty components, and preventive maintenance, which includes tasks like replacing filters and calibrating sensors. To effectively carry out these activities, a solid O&M strategy, complete with the necessary data and tools, is essential.
Acquiring data is crucial for successful O&M strategies for BESS systems. Power Factors obtains data from the battery management system (BMS), power plant controllers (PPC), and supervisory control and data acquisition (SCADA) systems through communication gateways and secure networks. Important data to monitor includes cooling system status, cell imbalance, state of charge, state of health, cycle counts, and depth of discharge.
Monitoring for BESS systems in different locations, such as New York and Arizona, requires adjusting O&M strategies based on weather conditions. Arizona systems may focus on high temperature conditions, while New York systems must consider cold weather and potential extreme events like hurricanes. Understanding these dynamics and having a proactive maintenance plan is crucial to maximizing revenue and system performance.
