When a utility solicits utility scale solar, it often asks bidders to price more than one way to acquire the project. The two that show up most are a power purchase agreement, where the developer keeps and operates the asset and sells the output, and a build transfer agreement, where the developer builds the project and hands ownership to the utility at completion. A developer that prices only one when the utility wants both is at a disadvantage before the evaluation starts.
Who Asks Solar Developers to Price PPA and Build Transfer
The large investor owned utilities that own generation, including Duke, Dominion, and many of the all source buyers, frequently run dual track solicitations that ask for both a PPA price and a build transfer price. The build transfer lets the utility rate base the asset, while the PPA keeps it off the balance sheet, so the utility compares both. These run on the utility pages and on Wood Mackenzie Supply Chain.
Why the Structure on a Solar Tender Is Easy to Miss
The structure the utility wants is rarely in the title. A build transfer prices every development and construction contingency into the bid with no post contract upside, while a PPA carries operating risk over a twenty year term, so the same project is bid very differently. The requirement to price both, and the format each must follow, sit in the pricing instructions deep in the package.
How an AI Bid Agent Flags the Solar Structure on Every Tender
An AI bid agent reads each solar solicitation and extracts whether the buyer wants a power purchase agreement, a build transfer, a capacity purchase, or more than one, and flags each separately because each carries risk differently. It pulls every new solar tender from the platforms the developer is registered on and delivers the qualified ones with the structure and the pricing format already extracted.
