Post-COD BESS review for owners who want the field truth, not the handover story
Many battery projects leave COD with a clean paper trail but an uncertain operating future. Oxaide helps owners and operators test whether the live battery is behaving the way the commissioning narrative promised.
What usually goes wrong
Underperformance, thermal asymmetry, operating constraints, and unexplained drift often emerge after commissioning milestones are complete.
Why owners need an independent check
Project teams and OEMs are usually too close to the original narrative. Owners need a cleaner read on what the asset is actually doing under real duty cycles.
Why this matters commercially
Post-COD drift changes availability assumptions, maintenance expectations, insurer posture, and the confidence with which the asset can be managed or refinanced.
What a stronger post-COD review should look at
Reality check for operating assets
Post-COD review is where owners separate a project that commissioned well from a battery that will actually behave well.
The goal is not to relitigate the project. It is to determine what the live asset now requires operationally, commercially, and technically, based on auditable evidence.
Mandate routing
Route the review to the right decision room.
If the site is already operating and the field story no longer matches commissioning assumptions, treat it as post-COD work and read the site as it is now.
Due diligence
Acquisition, portfolio transfer, or buyer-side underwriting where usable capacity and downside have to survive scrutiny.
Warranty
Claims, disputes, renewals, and OEM conversations that need clean, independent language.
Post-COD
Live assets where field behaviour has drifted from the commissioning or handover story.
Insurer
Claims, renewals, and underwriting review where asset condition needs to be clear beyond OEM posture.
Refinancing
Lender, covenant, and credit processes where the battery story needs to support downside assumptions.
