Power Purchase Agreement (PPA)
Produces a commercially balanced, regulation-aware agreement for the sale and purchase of electric energy between a generator and an offtaker.
Quick Start
Gather before drafting:
- Parties — legal names, jurisdictions, signatory authority, guarantors.
- Project — facility type, location, capacity (MW), technology, COD targets, interconnection status.
- Delivery — delivery point, ISO/RTO or utility territory, scheduling/dispatch model.
- Commercial — term length, pricing model, escalators, payment cycle, taxes.
- Attributes — REC/carbon ownership, transfer mechanics, certification requirements.
- Risk — curtailment allocation, force majeure, change-in-law, credit support, insurance.
- Operations — metering standards, testing cadence, data interfaces.
- Finance — lender requirements, step-in rights, consent rights (if project-financed).

Core Workflow
1. Key Definitions
Define these precisely — they drive pricing, performance, and defaults:
| Term |
Define |
| Contract Capacity |
MW/kW, net of parasitic load |
| Delivered Energy |
kWh/MWh measured at delivery point |
| Net Output |
Adjustments for losses/auxiliary load |
| Commercial Operation Date |
Objective tests and certification criteria |
| Force Majeure |
Scope, exclusions, duration caps |
| Availability |
Calculation formula and exclusions |
| REC/Environmental Attributes |
Registry, certification, transfer mechanics |
2. Conditions Precedent
Set deadlines for each; specify consequence of non-satisfaction:
- Permits/licenses obtained and in force
- Interconnection agreement executed
- Construction milestones met; COD evidence delivered
- Insurance with required endorsements in place
- Credit support posted and accepted
- Regulatory approvals (if applicable)
3. Pricing Model
Select one and fully specify:
| Model |
Key Inputs |
| Fixed energy price |
$/MWh, escalator, start date |
| Indexed price |
Index, reset frequency, floor/ceiling |
| Time-of-delivery |
Peak/off-peak bands, seasonal tables |
| Capacity + energy |
Capacity payment, availability test |
| Pay-as-produced |
Output-based with curtailment rules |
4. Metering and Data
- Accuracy requirement (e.g., ±0.5%)
- Calibration frequency and standards
- Data delivery method and timing
- Dispute process and true-up timeline
- Loss factor allocation between POI and delivery point
5. Performance and Liquidated Damages
| Metric |
Measurement |
Remedy |
| Availability (% annual) |
Defined formula |
LDs per shortfall |
| Energy guarantee (MWh/period) |
Net Delivered |
LDs or make-whole |
| COD delay (days late) |
Milestone dates |
LDs per day |
LDs must be a reasonable pre-estimate of loss, not a penalty.
6. Default and Remedy Framework
- Cure periods by type: payment (short), non-monetary (longer), insolvency (none)
- Termination rights and effective-date mechanics
- Damages: cover costs, replacement power, termination payment calculation
- Lender step-in/cure rights (only if finance structure requires)
7. Exhibits (minimum set)
- A — Facility description, POI, single-line diagram
- B — Pricing tables, escalation schedule, example invoices
- C — Metering specs, testing protocol, data format
- D — Form notices, designated recipients
- E — Credit support forms (LOC/guarantee)
Pitfalls and Checks
- [VERIFY] jurisdiction-specific regulatory approvals, ISO/RTO tariffs, and interconnection rules before finalizing.
- Align REC/carbon transfer language with registry requirements and buyer compliance targets.
- Keep curtailment rights symmetrical or clearly allocated — avoid implied take-or-pay conflicts.
- Tie COD, availability, and performance tests to objective, auditable criteria.
- Ensure delivery point definitions are consistent across main body and exhibits.
- Match confidentiality/announcement clauses to financing and regulatory disclosure obligations.
