A power purchase agreement transfers the capital cost, construction risk, and operational complexity of a solar or storage asset to the project developer or financier — while locking in a fixed or index-linked electricity price for the offtaker. Apex Grid operates as both developer-sponsor and independent advisor depending on project structure. Where we are not the asset owner, we represent the offtaker's interests exclusively through the negotiation process and into contract execution.
PPA Structures We Deploy
There is no single PPA structure that fits every situation. A behind-the-meter arrangement for a manufacturing site has different credit, metering, and curtailment characteristics than a sleeved corporate PPA drawing from a remote utility-scale generator. Apex Grid has delivered both, along with hybrid arrangements that combine on-site generation with firming from grid-scale battery storage or virtual power plant aggregation.
- Behind-the-meter PPAs: developer finances, owns, and operates on-site solar or storage, offtaker pays per-kWh below retail tariff
- Sleeved corporate PPAs: offtaker contracts with a remote generator, energy sleeved through the grid with retailer involvement
- Virtual PPAs (financial contracts for difference): hedge against wholesale price exposure without physical supply obligation
- Hybrid PPAs combining solar generation with BESS firming capacity under a single agreement
- Green power agreement structures with LGC or REGO transfer provisions
- Project finance debt structuring: non-recourse or limited-recourse debt, including CEFC-backed facilities and state green bond programmes
- Revenue-grade modelling at P50, P75, and P90 to satisfy lender technical due diligence requirements
Technical Due Diligence and Bankability
Lenders and equity investors require independent technical assessments before committing capital to generation or storage projects. Apex Grid's engineering team produces bankable energy yield assessments, technology risk reports, and construction plan reviews that satisfy the technical due diligence requirements of major project finance banks, infrastructure funds, and government green finance institutions. Our reports are accepted as lender technical advisor deliverables without third-party re-review in most cases.
We model every project against the Australian Energy Market Operator's marginal loss factor register, dispatch constraints, and network access conditions. For projects above 5 MW, we conduct connection pre-studies in parallel with PPA structuring so that grid access constraints do not derail a deal at financial close.
Contract Negotiation and Administration
PPA contract negotiations are technically complex. Curtailment risk allocation, metering protocols, change-in-law provisions, LGC transfer mechanics, and force majeure definitions all have material financial implications. Apex Grid's advisory team has negotiated more than 60 PPA and project finance agreements. We do not use generic templates. Every agreement is structured around the specific technology, grid connection, and commercial risk profile of the project. Post-financial-close, we provide ongoing contract administration, LGC and REC registry management, and performance reporting against contracted generation profiles.
