Where business case, contract, and technical reality intersect.
Pre-financial-close advisory for BESS Developers, IPPs, Investors, and Lenders — making sure your commercial assumptions, contractual terms, and technical parameters actually agree before signatures are committed.
Business case. Contract. Technical reality.
Rarely checked — until now.
Most BESS due diligence happens in silos: legal counsel drafts the contract, an independent engineer reviews the technical design, and a finance team builds the model — but due to underlying complexities, key dependencies are often overlooked.
Legal
Drafts the contract — warranty terms, LD caps, conditions precedent.
Engineering
Reviews the technical design — degradation, augmentation, performance.
Finance
Builds the model — revenue stack, opex assumptions, returns.
Breaking down the silos.
I work at the intersection of all three, making sure a project's commercial assumptions, contractual terms, and technical parameters are mutually consistent before money and signatures are committed.
Contract-to-business-case alignment review
A structured review of a draft or executed supply, EPC, or services agreement against the financial model and technical specifications, flagging where they diverge.
Technical due diligence for investment & lending
Supporting investors or lenders through diligence with a lens on whether contractual technical terms hold up commercially, not just technically.
Negotiation support
Sitting alongside legal counsel as the technical-commercial translator during contract negotiation.
Pre-NTP and Pre-FID review
A fresh-eyes check before signing, focused specifically on misalignment risk between contract, model, and technical reality.
5 years inside a leading BESS OEM.
I'm Bernhard Schlagbauer. For 5 years I worked as a Sales Engineer at Fluence Energy on battery energy storage systems, from the development phase through to contracting and Notice to Proceed.
That gave me a rare combination: deep technical BESS knowledge — system design, performance parameters, scope due diligence — alongside direct experience negotiating and closing large, complex contracts. I know how suppliers think and where they build in flexibility or risk, because I used to sit on that side of the table.
Have peace of mind.
If your deal is heading toward signatures, this is the moment to get a second, independent read on whether the business case, the contract, and the technical reality actually agree.
