Overview
This is a working document, not a market report. It assumes you are about to sign something, or about to ask someone else to.
Power purchase agreements are priced as one number and negotiated as a dozen separate decisions. This guide separates them: what you are actually buying, how price forms and why capture rates broke the standard corporate PPA, which risks belong on which side of the table, and what a credit committee will and will not finance.
Written for both chairs. Every risk is read from the buyer’s side and the seller’s, because the price of conceding a point is only legible when you can see what it is worth to the person asking for it.
What this guide covers
Sixteen parts covering the full negotiation — the map of who sits where, diagnosing which of five market types you are in, choosing between physical, sleeved, virtual, retail and captive structures, what you are really buying, price formation and the capture problem, testing the counterparty, the term sheet, the risk register, bankability, negotiation sequence, execution and settlement, life of contract, pitfalls, a worked example across three archetypes and five years of settlement, accounting and tax, and endgame. Closes with a five-page tear-out field checklist, a market annex by archetype, and reference appendices including a clause concordance.
