Thermal Cycling and Fatigue Assessment for Operational Battery Storage Asset

Client Context
An owner-operator experiencing higher-than-expected cycling frequency due to grid dispatch patterns.

Challenge
Original EPC design assumptions did not reflect actual duty cycles, raising concerns over accelerated degradation.

Equitus Role
Equitus assessed:

• Thermal cycling impacts on container structures

• Fatigue accumulation under real operating profiles

• Implications for asset life and repowering timing

Outcome

• Quantified degradation risk under actual operation

• Supported revised operational and maintenance strategies

• Informed long-term reinvestment planning

Value to Asset Owner
Improved asset life forecasting and IRR protection.
