- Where capital is abundant, capital may no longer be the main constraint. Funding decisions then depend on whether land, approvals, connection, procurement and contracts are sufficiently resolved.
- A model is not a project. A financial model describes the project; it cannot resolve missing rights, approvals or contracts.
- A connection or approval date is not a fixed milestone. A delay can increase capital cost, postpone or reduce revenue, and weaken debt-service coverage.
- Merchant income improves the equity case, while contracted income supports debt service. For an industrial energy-as-a-service structure, that contracted income is a fixed, invoiceable service fee a lender can underwrite.
- Industrial solar and battery projects have less standardised capital structures than utility-scale projects, so an early screen matters more.
Utility-scale battery finance is oversubscribed
The lesson comes from utility-scale battery finance, a market Heliovulcan does not work in. The comparison is indirect but useful for industrial and weak-grid projects. In utility-scale, debt raises are reportedly “multiples oversubscribed”: more capital is available than there are construction-ready projects to absorb it. Where that is the case, the constraint is upstream of the money, in the connection queue and in the contract structure over the asset.
Industrial projects face the opposite position. Fewer lenders have standard processes for weak-grid industrial battery projects, so developers may need to provide more project-specific evidence. This makes complete project evidence especially important.
Capital follows demonstrable project readiness
Where capital is widely available and construction-ready projects are scarce, the value sits with whoever can produce one: land secured, approvals in hand, connection confirmed, procurement arranged and offtake contracted. Low-cost capital alone does not distinguish a project; the ability to resolve risk does. Investor attention is also scarce. An investor with ten suitable assets in front of them can properly review only two or three at a time, so projects compete partly on how easy they are to underwrite. Clear evidence can shorten lender review, which is part of a financing strategy.
A delay changes both the cost and the revenue assumptions
The two dates that most often gate financial close are the connection date and, on industrial sites, the approval date. Neither should be treated as fixed: each week of delay changes the cost and revenue assumptions that follow from it.
The equipment supplier quotes against an assumed delivery date, and the customer prices its contract against the same date. If the date slips, both are reopened. The supplier adds an uncertainty premium, which raises capital cost, and the customer discounts for the same uncertainty, which lowers contracted revenue. One date therefore moves both the cost line and the revenue line:
A delay can increase capital cost, postpone or reduce revenue, and weaken debt-service coverage at the same time.
If the model holds the approval or connection date fixed, it understates both the possible cost increase and the loss or delay of revenue. Both effects can reduce the debt-service coverage ratio, the measure lenders use to test whether cash flow covers debt payments. The approvals and connection screens exist to surface that early.
Lenders rely mainly on contracted revenue
A project is rarely fully contracted or fully merchant, and how much revenue is contracted sets the capital structure. A fully merchant project attracts more conservative terms: lower gearing, higher pricing, cash sweeps and a shorter term. A contracted base gives the lender revenue it can rely on for minimum debt service, which makes merchant income above it easier to fund. Some structures add a gearing step-up, where lenders agree in advance to release further debt as the sponsor secures more contracted revenue.
For an industrial energy-as-a-service structure, the contracted revenue is a fixed service fee that can be invoiced and underwritten. Merchant or behind-the-meter income can improve the equity case, but debt should not be sized against it, for the same reason that customer savings should be separated from project revenue.
The observations above draw on Harrison Moore (Partner, Azure Capital; adviser on 10 GW+ of battery transactions) in conversation with Modo Energy’s “The Transmission”. Reported signal: debt raises “multiples oversubscribed”; a connection-queue “log jam” against AEMO / network processing capacity; a current 200–400 MW sweet spot; financing roughly six months end to end. Crucially, no DSCR, gearing, tenor or CAPEX/MWh figures were disclosed — so none of this is a benchmark. Treat it as informed practitioner opinion about direction, not verified data.
What this means for industrial PV+BESS
Utility-scale has standardised its structures enough that capital can move quickly once a project is ready. Industrial, weak-grid and EaaS projects have not — every one is a slightly different bundle of approval, site, connection, contract and credit. That lack of standardisation is why a disciplined early screen adds value: the four-part screen tests whether a project is moving towards financeability or only producing attractive spreadsheet outputs.
