Summary
Summary
kWh Analytics' 2026 Resilient Power Report highlights how operational discipline significantly reduced renewable energy losses for various operators. The report details the implementation of automated controls and hardware design improvements that mitigated damage from severe weather events. Notably, a solar site in Texas experienced less than 0.02% damage during a hailstorm, while a battery storage owner cut expected thermal event losses by approximately 95%.
Background
The report features multiple renewable energy operators, including Clearway and Madison Energy Infrastructure, who collectively manage significant investments in solar and battery storage technologies. Prior to the deployment of advanced operational strategies, these operators faced substantial risks from extreme weather events, such as hailstorms, wildfires, and winter storms, which threatened their assets and financial stability.
Challenge
Operators aimed to address the high risk of equipment damage and operational losses caused by severe weather conditions. For instance, a battery storage owner was particularly concerned about potential HVAC failures leading to thermal runaway, which could result in eight-figure losses.
Solution
To combat these challenges, operators implemented various solutions. Clearway utilized automated hail-stow technology on their solar trackers, which tilted panels to a protective angle before storms. Meanwhile, the battery storage owner adjusted charge-discharge cycling to allow HVAC systems to cool and installed single-use fuses between battery modules to prevent fault propagation. Other operators redesigned HVAC systems and improved hardware components to enhance resilience against extreme weather.
Results
The implementation of these strategies yielded significant results. Clearway's automated hail-stow system protected over 1 million solar modules, resulting in less than 0.018% damage during a severe hailstorm. The battery storage owner reported a 95% reduction in expected losses from thermal events after installing fuses and modifying operational strategies. Additionally, Madison Energy Infrastructure's proactive snow management returned 6 megawatts of solar capacity to service 10 days sooner than natural melt would have allowed.
Key Insights
The case studies illustrate the importance of proactive operational strategies and robust hardware design in mitigating risks associated with renewable energy assets. Investing in automated controls and improving equipment design can lead to substantial reductions in damage and operational losses during extreme weather events.
