A battery can earn from several markets, but that revenue is volatile, so developers and financiers often want a contract that converts it into something predictable. The most common structures are the tolling agreement, where the buyer pays a fixed fee for the right to operate the battery and capture its market value, and the capacity or resource adequacy contract, where the buyer pays for the battery's availability. For a storage developer, the offtake structure determines how bankable a project is.

These contracts shift the market risk and the operating control between the developer and the buyer in different ways, and a solicitation will usually specify the structure it wants. A developer that understands the offtake structures bids a project that can actually be financed.

What the Main Storage Offtake Structures Are

Under a tolling agreement, the buyer pays the developer a fixed capacity payment for the right to charge and discharge the battery as it chooses, capturing the energy, capacity, and ancillary services value, while the developer receives a predictable fee regardless of how the market moves. Under a capacity or resource adequacy contract, the buyer pays for the battery's availability and capacity contribution, often leaving some of the market participation with the developer.

Each structure converts volatile merchant revenue into a contracted stream to a different degree, which is why financiers favor them.

How the Structure Shifts Risk and Control

A tolling agreement gives the buyer operational control and the market upside while giving the developer a fixed, bankable payment, so the developer sheds market risk but also the upside. A capacity contract pays for availability while the developer may retain some market participation, balancing certainty and upside differently. A fully merchant project keeps all the upside and all the risk.

Because the structure determines who carries the market risk and who controls dispatch, a developer prices each differently and matches the structure to its financing.

The Terms That Decide a Tolling or Capacity Bid

A tolling or capacity contract turns on the fixed payment, the term, the availability and performance the developer must guarantee, and the penalties for failing to deliver, alongside who controls dispatch and who keeps the market revenue. The augmentation obligations to maintain capacity over time, and the round trip efficiency and degradation assumptions, all shape the bid.

The contract also sets the security and the conditions, and the buyer's creditworthiness matters because the developer is relying on the fixed payment for years.

Why Storage Offtake Tenders Are Easy to Miss

The offtake structure, the payment, and the obligations sit in the commercial terms of a solicitation, and a developer focused on the headline can misjudge how bankable the structure is or how much risk it carries. The structure a buyer wants, and how it allocates risk and control, varies between solicitations.

A developer that proposes the wrong structure, or misprices the availability obligations, can win a contract that does not finance or carries more risk than it priced.

How an AI Bid Agent Surfaces Every Tolling and Capacity Tender

An AI bid agent reads each storage solicitation and extracts the offtake structure, the fixed payment, the availability and performance obligations, and who controls dispatch and keeps the market revenue, and pairs them with the developer's financing needs. It scores how bankable and how risky each structure is.

It delivers the storage offtake opportunities in a ranked daily digest, so a developer pursues the structures it can finance and prices the obligations correctly.
