Two years ago, a developer with a good site, a signed power purchase agreement and a credible sponsor could expect most development lenders to engage. That is still broadly true. What has changed is the order and the depth of the questions they ask, and how early they expect the answers.
Across the solar and storage mandates we have worked on this year, the projects that reached financial close quickly were not always the largest or the cheapest. They were the ones that had already answered the questions lenders now ask first.
Grid risk sits at the top of the list
The first conversation with a credit team is now about the grid, not the panels. Can the network take the power? Who carries the cost if the utility cannot dispatch it? How is curtailment measured and paid for? A power purchase agreement that leaves these questions open will be sent back, however attractive the tariff.
The fix is rarely technical. It is contractual: clear deemed energy provisions, a grid study the utility has accepted, and a realistic view of how often the plant will be asked to stop.
Lenders rarely walk away from a good site. They walk away from a risk nobody has priced.
Storage needs its own case
Adding batteries to a solar plant makes sense for utilities that need power after sunset. It does not automatically make sense to a lender. Credit teams want to see how the storage is paid for, whether through a capacity charge, a separate tariff or a clear share of the energy payment, and what happens as the batteries degrade.
Land and community agreements come earlier
Environmental and social standards have not changed much. What has changed is when lenders want evidence that they are met. Land title, resettlement plans and community agreements are now expected at concept stage. Projects that leave them until after permits often lose months.
What developers can do now
- Agree the grid study and dispatch rules with the utility before negotiating tariff.
- Model storage revenue separately and show lenders the downside case.
- Start land and community work alongside feasibility, not after it.
- Bring one development lender in early to test the structure informally.
None of this is new advice. What is new is how firmly lenders now expect it, and how much faster the projects that follow it are closing.
