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

1

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.

2

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.

3

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.

4

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.

5

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). 

6

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. 

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

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.

• Receipts are consumed. Once issued, the period’s ETT are locked; re-use later is impossible.

• Factor transparency. We record EF sources & versions on-chain; no ad-hoc repricing of settled vintages.

• 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_{t gross}; 10% uncertainty+buffer → 1,755 t saleable.

At

• $20/t → $35,100 gross / $34,398 net;

• $40/t → $70,200 / $68,796;

• $50/t → $87,750 / $85,995.

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

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_{t gross}; 12% haircut → 1,887 t saleable.

At

• $20/t → $37,740 gross / $36,985 net;

• $40/t → $75,480 / $73,970;

• $50/t → $94,350 / $92,463.

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_{t gross}; 10% haircut → 756 t saleable.

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

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.

Non-negotiables

• Ex-post only

• Off-grid/diesel-dominant or reroute to R1/R2

• 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

• 50% burn on every fee until 100 M circulating.

Cross-links

• PoV Layer (§9) — quorum, equality, one-claim

• Fees/Tokenomics (§14/§18) — 4% rule, denomination floor, 50% burn

• Routes (§20) — compatibility with R1–R2 (attributes/flex) and R4 (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.
