Many utilities no longer solicit a single technology; they run all source procurements that let wind, solar, storage, gas, and hybrids compete head to head to meet a need. An all source solicitation defines what the utility needs, energy, capacity, or clean power, and invites every resource that can serve it to bid, choosing the best value regardless of type. For an independent power producer, these procurements are a major channel, and winning means understanding what the utility truly values across competing technologies.
Because an all source procurement pits technologies against one another, a developer must position its resource against the alternatives the utility is also considering. A developer that reads what the solicitation values competes on the terms that decide the award.
What an All Source Solicitation Is
An all source request for proposals asks the market to meet a defined need, such as a quantity of capacity, energy, or clean power by a certain date, without specifying the technology, so wind, solar, storage, gas, hybrids, and others all compete. The utility evaluates the bids on cost, reliability, and fit to its needs, often through an integrated resource plan that set the need in the first place. The best value resource, whatever its type, wins.
This lets the utility find the cheapest reliable way to meet its need, and it forces resources to compete across technology lines. A wind project, then, is judged not only on its own merits but on how it compares to every other way the utility could meet the same need.
Why Utilities Use Them
All source procurement has become common because it lets a utility compare every option and get the best value, rather than committing to a technology in advance, and regulators often favor it for that reason. It also surfaces hybrids and combinations the utility might not have specified, and it lets storage and renewables compete with gas on cost and reliability. The result is a single process where many resources vie for the same need.
Because the utility is choosing among technologies, a developer must show why its resource is the best answer to the need.
The Terms That Decide an All Source Bid
An all source opportunity turns on the need the utility is filling, energy, capacity, clean power, or a mix, the evaluation criteria across cost and reliability, the delivery timing, and how competing technologies stack up against the bid. Because the resource must beat alternatives, a developer must understand the need and the criteria deeply and position accordingly.
The reliability and capacity value, the cost, and the fit to the timing shape whether a resource wins against the others.
Why All Source Tenders Are Easy to Miss
All source solicitations come from many utilities on their own schedules, often tied to resource plans, and the need and criteria that decide them sit in long technical documents. A developer not tracking these can miss procurements where its resource could compete and win.
The cross technology evaluation and the detail in the criteria make these opportunities hard to read quickly by hand.
How an AI Bid Agent Surfaces Every All Source Tender
An AI bid agent monitors the utilities' all source solicitations and the resource plans behind them, reads each opportunity, and extracts the need, the evaluation criteria, the timing, and how the developer's resource stacks against the alternatives. It scores fit and competitiveness.
It delivers the all source opportunities in a ranked daily digest, so an independent power producer reaches the procurements where its resource can win against the field.
What the AI Bid Agent Extracts From Each All Source Tender
- The need the utility is filling
- The evaluation criteria across cost and reliability
- The delivery timing required
- How competing technologies stack against the bid
- The resource plan behind the solicitation
- The capacity and reliability value the resource must show
You can see this approach running, the live feed, the fit scoring with written reasoning, and the daily digest, in our renewable energy bid discovery hub, which monitors solicitations across renewable segments including wind and all source procurement. Our utility scale solar PPA bid agent demo is a worked example of one segment, and once you decide to pursue a solicitation our renewable bid response agent reads the full package, builds the requirements matrix, and red teams the draft before submission.
