How Smart O&M Unlocks Profitability for Remote ESS Plant

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.

1. Four Major Pain Points in O&M of Remote Energy Storage Power Stations

1.1 High Manual Inspection Costs  

Traditional O&M relies on periodic on-site inspections, which incur significantly higher transportation and labor costs in remote areas.

1.2 Slow Fault Response  

Grid fluctuations and equipment malfunctions are difficult to diagnose in real time, increasing the risk of battery thermal runaway under extreme conditions.

1.3 Data Silos and Energy Losses  

Incompatibility among device protocols prevents dynamic optimization of charging and discharging strategies, leading to solar curtailment rates of up to 15%.

1.4 Long Spare Parts Supply Chains  

Reliance on imported spare parts results in downtime lasting several weeks, adversely affecting power station revenue.
