BESS technical due diligence for buyers who need the real asset story
Oxaide helps investors, lenders, and asset teams test whether reported battery health matches commercially usable reality, so pricing and downside assumptions are set from evidence, not vendor optimism.
What serious buyers need answered
How much usable capacity is actually there, what degradation is underway, and whether those findings change revenue assumptions, downside cases, or reserve planning.
Where standard diligence breaks
Warranty packs, BMS screenshots, and availability summaries do not automatically reveal physical condition. They describe the reporting layer, not always the cell reality underneath it.
Why this is high-stakes capital work
BESS deals look excellent on paper until hidden degradation, thermal risk, or operating constraints start eroding IRR. The bigger the deal, the more expensive weak diligence becomes.
What a stronger diligence pass actually includes
The goal is not another glossy diligence memo. It is an evidence set that can survive IC scrutiny, financing questions, warranty debate, and post-close operating reality.
Commercial truth before commitment
The point is not to slow the transaction. It is to stop capital from underwriting a battery story the physics cannot support.
Good diligence does not kill good assets. It helps serious buyers move faster with better pricing discipline, stronger protections, and a cleaner post-close operating plan.
Mandate routing
Route the review to the right decision room.
If price, reserves, or SPA protections are on the line, treat it as diligence work and keep the proof easy to inspect.
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.
