# R9: Diesel–Solar Microgrids

## What this route does. 

R9 pays for **measured, avoided emissions** when off-grid or diesel-dominant sites replace genset output with **PV + BESS**. We bind two evidence spines: **ETT** (on-chain receipts of PV production, **1 ETT = 10 kWh**) and a **diesel baseline pack** (fuel logs, runtime, SFC curves). A verifier signs the dossier; EDMA **issues tons ex-post**; you sell; settlement runs on-chain. Fees are in $EDM (2% seller at claim, 2% buyer at settlement); **50% of every fee burns** until circulating supply reaches 100 M. **No evidence → no ton → no settlement**.  

### Who & where this fits

**Operators**. 

Remote mines/camps, islands & resorts, telecom BTS fleets, construction & humanitarian microgrids—anywhere **diesel is the default** and PV/BESS can displace it. 

**Buyers** are corporates retiring defensible reductions tied to real diesel they didn’t burn. 

**Price reality:** well-metered, conservative packets commonly **clear $20–$50/t.** 

### PoV in Action

{% stepper %}
{% step %}

### Capture & Sign

Connect PV/BESS SCADA or meters; EDMA mints **ETT** as verified PV kWh land (**1 ETT = 10 kWh**). In parallel, upload the **diesel pack**: bulk & day-tank fuel logs, runtime meters, genset nameplates & **SFC curves** (g/kWh); fuel-flow meters if available. All records are time-synced and hashed into canonical evidence. **ETT are receipts, not credits.**
{% endstep %}

{% step %}

### Verify

A verifier reviews *the same* evidence: PV/BESS dispatch, curtailment, **round-trip efficiency (RTE),** parasitics; diesel liters/runtime and SFC; and—if needed—a **no-storage baseline**. Weak or malformed intervals are rejected here. 
{% endstep %}

{% step %}

### Gate

The **PoV Gate** enforces:

1. **Quorum present**
2. **Equality of evidence** (every counted attestation references the **same evidence** hash/window), 
3. **One-Claim exclusivity** (the route-agnostic claimId hasn’t finalized anywhere) \
   \
   **Fail =** **no mint, no issue, no settle.**
   {% endstep %}

{% step %}

### Lock the math

We publish your accounting plan before issuance so numbers can’t drift:

* Fuel path (simplest).

$$
\textbf{Avoided tCO₂}=\frac{(L\_{\text{baseline}}-L\_{\text{residual}})\times \mathbf{2.68}\ \mathrm{kg/L}}{1000}
$$

then apply **uncertainty** and **buffer**. 

* **kWh path (when SCADA is clean).**

  \
  $$\textbf{Avoided tCO₂}=\big(kWh\_{\text{diesel,baseline}}-kWh\_{\text{diesel,residual}}\big)\times EF\_{\text{diesel},kWh}$$

  \
  with **RTE losses, curtailment**, parasitics deducted; **EF** commonly **0.67–0.80 t/MWh** depending on SFC & loading. 
  {% endstep %}

{% step %}

### **Issue (ex-post), stamp ETT**

On verifier sign-off, EDMA **issues avoided-emission tons** for the period. The **ETT that backed those hours are stamped with batch IDs and become non-transferable**, enforcing one-claim law (those kWh can’t later be sold as energy attributes). 
{% endstep %}

{% step %}

### Sell & settle.

Pick **forwards/floors** (steady) or **spot** (chase highs). Cash settles in **stablecoins**; seller pays 2% in EDM at Claim; buyer pays 2% at settlement (EDM discount optional). **50% of every fee burns**; if you’re short of EDM, the transaction reverts cleanly—no auto-swaps. A $0.50/EDM denomination floor is used only to compute how many tokens are due; it is not a price peg. 
{% endstep %}
{% endstepper %}

**Outcome: capture → verify → PoV gate → issue → stamp ETT (consumed) → sell → EDM fees (50% burn) → immutable lineage. **
{% endhint %}

### Integrity by design (why buyers accept your tons)

* **Off-grid checks.** Eligibility requires **off-grid or diesel-dominant** operation; grid-tied slices route to **R1/R2** (attributes/flex) unless those attributes are retired first for carbon issuance.&#x20;
* **Receipts are consumed.** Once issued, the period’s **ETT are locked**; re-use later is impossible.&#x20;
* **Factor transparency.** We record **EF sources & versions** on-chain; no ad-hoc repricing of settled vintages.&#x20;
* **No side-selling**. Overlapping claims (double-counted liters or narratives) are denied; we can **slash bonds (burn)**, claw back, and blacklist.

### Worked scenarios

#### A) Island resort — 1.2 MWp PV + 2 MWh BESS; 65% displacement

Baseline diesel generation **4.0 GWh/yr** → residual **1.4 → 2.6 GWh displaced.**

2.6 x 0.75 = 1,950<sub>t gross</sub>; 10% uncertainty+buffer → **1,755 t saleable.**

At&#x20;

* $20/t → $35,100 gross / **$34,398 net**;&#x20;
* $40/t → $70,200 / **$68,796;**&#x20;
* $50/t → $87,750 / **$85,995**.&#x20;

**Prefund @ $40/t:** \
\
$$0.02 \times \frac{70,200}{4} = $351.$$<br>

#### B) Telecom BTS — 1,000 sites; hybrid PV/BESS

Baseline **2,000 L/site/mo** → post-retrofit **1,200 → 800,000 L/yr avoided.**

800,000 x 2.68/1000 = 2,144<sub>t gross</sub>; **12%** haircut → **1,887 t saleable.**

At&#x20;

* $20/t → $37,740 gross / **$36,985 net**;&#x20;
* $40/t → $75,480 / **$73,970**;&#x20;
* $50/t → $94,350 / **$92,463.**&#x20;

**Prefund @ $40/t:** \
\
$$0.02 \times \frac{75,480}{4} \approx $377.4.$$

#### C) Construction microgrid — 800 kWp PV + 1.2 MWh BESS; 40% displacement

Baseline **3.0 GWh/yr** → residual 1.8 → **1.2 GWh displaced.**

1.2 x 0.70 = 840<sub>t gross</sub>; 10% haircut → **756 t saleable.**

At $20/$40/$50/t → **$15,120/$30,240/$37,800 gross**; net after 2% seller fee accordingly. &#x20;

### What you actually do (week 1 → first payout)

* **Day 1:** KYC + whitelist wallet (stablecoin rails). Confirm **diesel-dominant** status & PV/BESS commissioning dates.
* **Connect data:** PV/BESS SCADA + diesel logs/meters; **ETT** begin minting as PV kWh land.
* **Prefund (EDM):** \
  $$\textbf{Admission Prefund (USD)}=\min\big(\max(0.02\times \text{projected 3-month gross},\ $20),\ $1{,}000\big)$$
* **One-tap buy:** the fuel gauge shows how many claims your balance covers
* **Then:** **monitor → dossier → verify → issue → sell → claim**. Usual issuance quarterly (monthly once SCADA stabilizes).

### Fees & settlement (canon)

EDM is gas and fee. 4% total per sale (2% seller at claim; 2% buyer at settlement), **50% of all fees burn**, and the $0.50/EDM figure is a fee-denomination floor, not a market peg. If a wallet is short, the transaction reverts; we never auto-swap your payouts.&#x20;

### Non-negotiables

* **Ex-post only**&#x20;
* **Off-grid/diesel-dominant** or reroute to [<mark style="color:$primary;">R1</mark>](https://docs.edma.app/20.-routes/r1-compliance)/[<mark style="color:$primary;">R2</mark>](https://docs.edma.app/20.-routes/r2-granular-and-flex)
* **One-claim law** (ETT consumed; retire attributes first if they ever exist)
* **Conservative math** (RTE, curtailment, part-load SFC, uncertainty, buffers)
* **EDM only**; no auto-swap&#x20;
* **50% burn** on every fee until 100 M circulating.&#x20;

### Cross-links

* **PoV Layer** (§9) — quorum, equality, one-claim
* **Fees/Tokenomics** (§14/§18) — 4% rule, denomination floor, **50% burn**&#x20;
* **Routes** (§20) — compatibility with [<mark style="color:$primary;">**R1**</mark>](https://docs.edma.app/20.-routes/r1-compliance)**–**[<mark style="color:$primary;">**R2**</mark>](https://docs.edma.app/20.-routes/r2-granular-and-flex) (attributes/flex) and [<mark style="color:$primary;">**R4**</mark>](https://docs.edma.app/20.-routes/r4-energy-side-carbon) (emissionality) without violating one-claim.

**Bottom line**

Route 8 makes soils and biochar finance-grade: GRO-anchored evidence, conservative accounting, one-claim enforced in code, and EDM-settled payouts that burn on-chain. Buyers get tons they can defend; you get cash you can plan on.&#x20;
