The views, interpretations and teaching models are my own; they do not represent my employer or any other organization and carry no employer approval or endorsement. No confidential, proprietary or nonpublic employer information is used. Factual background comes only from publicly available sources. Maya of Stories Inc, the book vendor; Mayan of Sapiens Inc, the printing-machine supplier; and eComm Inc, the ecommerce company, are fictional teaching characters and companies. I appear as the customer in imagined scenes, not as a report of my actual purchases. These scenes do not describe any real company or its internal systems. The cases are separate teaching examples, not one continuous ledger. Scenario amounts, rates, terms and policies are illustrative assumptions unless expressly identified as dated public facts. Actual contracts, regulations, operations and economics require case-by-case analysis.

*Part 11 of 16 · Behind the Buy Button*

## The printing room needs power and a place to stand

Mayan's machine will not run on a purchase order. eComm Inc needs electricity and space. Separate, unnamed energy and property counterparties supply those contracts. Mayan remains the machine and service supplier; buying the equipment does not settle the power or premises obligations.

Energy and leases are useful tests of any model that tries to make every purchase look like a box of books.

[![Part 11: energy & leases. 1,000 MWh × ($50 − $40) per MWh = $10,000 payment Fictional teaching model.](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/behind-the-buy-button/figures/part-11.png)](https://storage.ghost.io/c/f5/a9/f5a9f801-5a10-44d6-b07c-6658660be1a9/content/images/behind-the-buy-button/figures/part-11.png?ref=abundance.alloconomy.com)

Each long-term promise needs the right evidence. ELECTRICITY — Metered MWh — Physical supply and applicable terms; FINANCIAL PPA — Price difference — A settlement may flow either way; LEASE — Available use — Commencement, schedule and modifications. Simplified financial-PPA example. Not a physical delivery claim or real deal price. Fictional example; see the nearby table and prose for an accessible explanation.

## The long-term-contract cheat sheet

| Arrangement                   | Relevant evidence                                           | Distinction to preserve                              |
| ----------------------------- | ----------------------------------------------------------- | ---------------------------------------------------- |
| Physical electricity purchase | Contract, delivery or metering and pricing                  | Capacity is not energy delivered                     |
| Financial energy agreement    | Contract formula, reference price and eligible volume       | Cash settlement is not physical electricity delivery |
| Environmental attributes      | Required certificate or attribute records                   | A payment alone does not prove transfer              |
| Property or equipment lease   | Agreement, availability, payment schedule and modifications | Signing is not necessarily commencement              |

The EPA explains [physical PPAs](https://www.epa.gov/green-power-markets/physical-ppa?ref=abundance.alloconomy.com) and, in an explicitly [archived conceptual reference](https://19january2021snapshot.epa.gov/greenpower/financial-power-purchase-agreements%5F.html?ref=abundance.alloconomy.com), financial PPAs. We use the distinction to understand the mechanism, not as current regulatory or deal-specific advice.

## A financial settlement can change direction

Assume a simplified financial power agreement covers 1,000 megawatt-hours, or MWh, with a fixed price of $50 per MWh. The agreement uses a specified market reference. For this illustration:

**Buyer payment = eligible MWh × (fixed price − reference price).**

At a $40 reference price, eComm Inc pays **1,000 × ($50 − $40) = $10,000**. At a $65 reference price, the result is **−$15,000**, meaning eComm Inc receives $15,000 under our assumed direction convention.

The formula excludes basis differences, volume adjustments, negative-price provisions, fees, collateral, tax and certificate terms. It is not a quotation of a real agreement. Its purpose is to show why a universal supplier-invoice-to-buyer-payment arrow is insufficient: the same formula can produce cash in either direction.

eComm Inc still needs a separate explanation of how its facilities obtain physical electricity. A financial settlement does not demonstrate that electricity from the referenced project flowed to this printing room.

## Megawatts and megawatt-hours answer different questions

Megawatts, or MW, describe power or capacity. MWh describe energy over time. A simplified relationship is **energy = average power × hours**. A 2 MW facility operating at that average for ten hours uses 20 MWh. Nameplate capacity alone does not establish annual generation.

A dated public example helps: RWE's [February 3, 2026 announcement](https://www.rwe.com/en/investor-relations/financial-calendar-and-publications/news-and-ad-hoc-announcements/news/news-2026-02-03/?ref=abundance.alloconomy.com) describes a 110 MW Amazon agreement associated with Nordseecluster B and scheduled commercial operation in 2029\. The announcement establishes a future arrangement, not delivery already occurring in 2026\. The date matters as much as the number.

## A lease also has more than one beginning

Assume eComm Inc signs a printing-facility lease in December, but the space becomes available for the agreed use in July. Signing establishes a contractual relationship. Availability is another event. The recognition analysis needs the actual terms and applicable accounting policy; a signature date alone cannot settle it.

A payment labeled “rent” might include a deposit, fixed rent, variable charges or reimbursements. These components need their own meanings. Renewal options and modifications can continue beyond the last invoice someone has marked paid.

For illustration only, three end-of-year payments of $10,000 discounted at 5% have a present value of:

**$10,000 ÷ 1.05 + $10,000 ÷ 1.05² + $10,000 ÷ 1.05³ ≈ $27,232.48.**

The undiscounted cash total is $30,000\. The present value and cash total are two measurements of the same assumed stream, not separate liabilities to add. A real lease includes additional classification and measurement questions that this calculation intentionally leaves open.

## What this changes in a capacity decision

Buying a machine, leasing equipment, renting space and buying a service can all help create capacity. Comparing only the current cash payment can hide future commitments and different risks.

eComm Inc's leaders need the obligations and the useful service on a common scope and time horizon. Mayan needs to understand whether the customer is buying an asset or paying for availability. An investor should resist calling one structure cheaper simply because less cash left the bank this quarter.

The practical question is: which promise continues after today's payment, and what evidence will show that it was fulfilled?
