Draft Ppa Seller Solar Plus Storage

Skill: Draft Power Purchase Agreement — Seller-Side for Solar-Plus-Storage Project

1. Subject-matter triage

• Treat the PPA as the primary deliverable and draft it first; do not let any note, summary, or issues list substitute for the agreement text.
• Extract and reconcile terms from the precedent, term sheet, negotiation record, and any attached project materials before drafting operative provisions.
• Separate the work into: agreed commercial terms, disputed terms, and open items requiring confirmation.
• Draft the seller-favorable position for each disputed point, while preserving a clear drafting note that identifies the issue and the alternative position.
• If the source set contains only one project, one seller, one buyer, or one facility configuration, state that affirmatively and draft on that basis rather than implying optionality.

2. Failure modes the skill is correcting

• The draft silently adopts one side’s position on a disputed term without disclosing the dispute or the competing position, hiding a client decision point.
• Force majeure relief is drafted to extend one deadline but not the related outside termination deadline, creating an internal timing mismatch.
• Storage dispatch language is left generic, so the agreement fails to define who controls charging and discharging, what operating limits apply, or whether any capacity is reserved for non-PPA uses.
• Performance security step-down language ignores lender-required conditions or reduces security before the contractual conditions for step-down are actually met.
• Tax incentive language assumes eligibility or compliance that is not yet confirmed, exposing the seller to disallowance risk.
• Prevailing wage and apprenticeship obligations are treated as construction-only concepts even though the project may need post-construction compliance for qualifying work.
• Termination payment caps are drafted asymmetrically without an explicit commercial rationale.
• Drafting notes are omitted on open issues, leaving the client without a decision record.

3. Legal frameworks / domain conventions that apply

• Use the source documents as the governing commercial record; where they conflict, prioritize the seller’s position in operative text and flag the conflict in a note.
• Draft all force majeure language and date-extension mechanics as a coordinated system; if a qualifying event extends the guaranteed commercial operation date, it should also extend any outside termination deadline by the same trigger and same day-for-day mechanic.
• For environmental attributes, define the transfer scope precisely and flag any mismatch between the precedent and the term sheet.
• For negative pricing and curtailment, anchor the seller’s curtailment right to the threshold reflected in the seller-favorable draft and identify any competing threshold from the source materials.
• For tax credits and incentives, include the seller’s compliance and adjustment language, but note any open eligibility assumptions, including site qualification or labor-rule dependencies.
• For battery storage, define dispatch rights, charge/discharge limitations, degradation protections, and any reserved capacity with enough precision to be operationally enforceable.
• For security packages, coordinate any letter of credit reduction with the project’s operating status and any lender-condition overlay reflected in the source set.
• For post-construction labor compliance, address qualifying repair, maintenance, alteration, and similar work during operations, not just initial construction.
• Cite the controlling legal or regulatory authority only when the drafting issue depends on a legal proposition in the source set or a generally recognized governing rule; otherwise keep the drafting note commercial and concrete rather than doctrinal.

4. Analytical scaffolds

• Build a term map before drafting: identify each commercial point, its source, whether it is agreed or disputed, and whether it needs a drafting note.
• For each disputed term, do three things in sequence: draft the seller-favorable clause, note the competing position, and recommend client resolution.
• For each open item, do three things in sequence: identify the missing fact, explain why it matters to the operative language, and request confirmation or supporting information.
• When drafting deadline mechanics, verify the same trigger, same extension formula, and same cross-reference appear in both the commercial operation deadline and the outside termination deadline.
• When drafting storage provisions, test the clause against three questions: who controls dispatch, what limits protect the asset, and whether any reserved capacity is carved out and protected.
• When drafting security provisions, test the clause against two conditions: project operating status and any lender-imposed gating condition.
• When drafting incentive language, test the clause against both qualification at inception and continuing compliance during operations.

5. Vertical / structural / temporal relationships

• Coordinate provisions that sit in different parts of the PPA but operate on the same event, especially force majeure, commercial operation, termination, security, and cure provisions.
• Make the timing hierarchy explicit: initial milestones, guaranteed commercial operation date, outside termination date, step-down date for security, and any post-COD compliance obligations.
• Ensure that any extension, tolling, or suspension mechanism reaches every deadline that depends on the same underlying event.
• If the project has separate solar and storage operational regimes, reflect the temporal relationship between charging, discharging, delivery periods, and any non-PPA reservation.
• Keep seller rights to reserve, curtail, or prioritize storage capacity temporally and operationally distinct from buyer delivery rights.

6. Output structure conventions

• Produce a complete PPA draft in conventional agreement form with drafting notes embedded at the relevant provisions.
• Use primary, non-bracketed text for the seller’s preferred operative language.
• Add a drafting note at every disputed term and every open item; the note should identify the issue, state the competing position or missing fact, and request client resolution.
• Keep drafting notes concise and functional; they should explain what must be decided, not recite the entire negotiation history.
• Do not omit clauses merely because they were not highlighted in the term sheet if they are standard for a 20-year utility-scale solar-plus-storage PPA.
• Confirm at the end that the named deliverable file has been produced and contains operative agreement text, not a summary or memo.
• If the source materials include legal authorities, cite them in the relevant drafting note or provision; do not make uncited legal assertions where authority is required.
