Energy decisions fail when models, money, and EPC schedules disagree.

Epsilon connects energy modeling, project finance, and EPC schedule reality on one spine. DER financiers use Schedule Realism Packs to defend COD. Climate and risk teams use financed scenario runs. NGOs deploying DERs use the EPC layer (BOM, lead times, and critical path) so construction plans survive equipment reality.

  • One stack: scenario engines to finance outputs to BOM↔schedule binding
  • Guided path from dashboard through report in the live app
  • Same diligence rigor for financed scenarios and EPC realism cases

Models, money, and EPC plans stay siloed

Point-estimate COD dates, orphaned financial models, and optimistic EPC schedules are three faces of the same failure: assumptions that never meet.

Capital and COD

Tax equity and lenders need equipment and schedule risk made explicit before close: a 12-week transformer slip can become a three-month COD miss and a covenant breach if the BOM is never bound to the critical path.

Models and finance

Sizing, stress, and dispatch live in one tool while IRR and NPV live in another spreadsheet; climate and transition teams need financed scenarios under shared assumptions, not a separate catastrophe hazard product.

NGO execution

NGO-backed and developing-world DER projects still depend on BOMs, lead times, and commissioning paths: an EPC plan that cannot survive transformer and inverter reality is advocacy without execution teeth.

30 to 60
Distribution transformers (weeks)
100 to 144
Utility-scale transformers (weeks)
16 to 36
Inverters (weeks)

Every week in the schedule should say whether it came from a quote, a category default, or a hopeful override.

Who uses Epsilon, and how

Same product stack: scenario engines, project finance, and EPC BOM↔CPM tooling. The job picks the pack.

DER capital

Schedule Realism Pack

Defends COD before tax equity or lender close. Bind equipment lead times to the critical path; quantify slip into carrying cost, IRR, and covenant narrative. Outputs include a procurement register, COD slip tornado, assumption ledger with provenance, and a risk register with costed mitigations.

Climate and risk

Financed Scenario Pack

Energy modeling plus financing, not climate-hazard forecasting. Size, stress, and dispatch scenarios wire into NPV, IRR, and payback under a shared assumption ledger, with stress bands (dunkelflaute, outages) and caveats suitable for transition-risk conversations.

NGO deployments

EPC Realism Pack

The EPC aspect of Epsilon: SKU-level BOM, lead-time bands, P6/XER or CSV ingest, and BOM↔CPM binding so commissioning plans survive equipment reality. It is a diligence layer on the EPC plan, not field ops software.

Shared path. Different entry points.

Financing and NGO packs usually start from BOM + schedule. Climate / risk packs often start from scenario inputs, then land on the same finance and assumption discipline. Delivered as a 72-hour service pack until self-serve matches what we claim.

  1. Dashboard: reliability, bankability, schedule, and site on one screen
  2. Define the scenario, then size the portfolio
  3. Microgrid economics: VPP and PPA revenue stacked into NPV and IRR
  4. BOM and schedule: lead times bound to the critical path, plus a COD tornado
  5. Stress-test dispatch under named bands
  6. Site diligence: land, HIFLD substation screening, and a decision card
  7. Report: comparison table and an audience export
  8. Optional depth stays inside steps (CostStack, SAM, REopt), not as extra nav items

Packs are still a 72-hour diligence service; the app is the stack behind them.

What it is
  • A diligence layer that connects scenario models, project finance, and EPC schedules
  • Registers, sensitivity, and ledgers those tools do not produce
  • 72-hour pack assembly against your inputs on a diligence timeline

Pricing is scoped per financing event or project after we see the file set.

What it is not
  • A P6 replacement
  • Procore or field execution
  • A climate-hazard or catastrophe model
  • A live OEM marketplace

Energy models wired to NPV and IRR

Climate and transition-risk teams that need energy modeling wired to finance use the same Scenario contract the product already runs. This is sizing, stress, and dispatch to NPV/IRR: explicitly not catastrophe or physical-hazard forecasting.

DC-PPA / portfolio sizing

Least-cost

Solar, wind, and storage portfolios against CFE or reliability targets, then hand off capacity into finance under shared assumptions.

ISO-RTO stress

Monte Carlo

Dispatch under dunkelflaute, EV growth, and outage bands. P50/P90-style outputs with caveats, for energy risk conversations, not insured-loss curves.

Microgrid financials

Dispatch + finance

Site-level dispatch with revenue stacking into NPV, IRR, and payback: the core of a Financed Scenario Pack walk.

VPP & feeder context

Optional depth

Market ABM and feeder hosting tools available when a scenario needs them; not claimed as real-time DERMS control.

Project finance pro-forma

Step 4

Construction draws, IDC, DSCR-sculpted debt, a 30% ITC plus an optional 10% domestic adder, and section 6418 transfer knobs. SAM yield and REopt sizing run only when configured.

Open the guided path

EPC deliverables. Same rigor for capital and NGO projects.

Schedule Realism Packs (DER financing) and EPC Realism Packs (NGO-backed deployments) share these outputs. Language shifts from IRR/covenant to commissioning milestones when the audience is a funder or ministry; the binder does not.

Procurement Register Export

CSV + XLSX

Long-lead items filtered by threshold (default: 20+ weeks). SKU, category, qty, lead_time_weeks, needed_by_date, status.

COD / commissioning sensitivity

Tornado

Slip what-ifs (+4 / +8 / +12 weeks) ranked by impact on COD or commissioning: the “schedule killers” list for IC or partner review.

Assumption Ledger

Provenance

Every lead time cites quote, category default, or override: the audit trail capital and DFIs expect.

Risk Register

Exposure + mitigations

Named risks, exposure (weeks / $ / MW), and mitigations: split procurement, expedite, partial energization.

Delta narrative

Change summary

What changed since last update: BOM lines, lead times, binding, forecast under baseline and downside.

BOM ↔ Schedule binding

CPM + procurement

Which equipment gates which tasks; coverage of critical-path tasks bound to procurement drivers. XER ingest: we do not replace P6.

Site diligence

Step 6

Land constraints, HIFLD substation distance, and a decision card with dollar-weighted exceptions, before NTP.

Shipped vs. service: what we will not oversell

Packs are 72-hour diligence deliverables. Sponsor equity IRR is computed in the app from construction draws, IDC, DSCR-sculpted debt, ITC face, and section 6418 transfer knobs. A living twin that rewrites the lender model on every BOM edit is not the claim.

Built and in use

Scenario engines, BOM to CPM binding, COD slip tornado, microgrid finance, the Step 4 pro-forma knobs above, HIFLD site screening, and audience reports.

Service layer today

Pack assembly, narrative, and deal-specific finance deltas may include manual steps. You can open the app; pack assembly remains a service, not a finished SaaS seat.

Not claimed

Live OEM marketplace, BYOK distributor pricing as production path, climate-hazard / catastrophe models, Procore-style field execution, automated underwriting decisions.

Pricing posture

Scoped per financing event or named project after we see inputs, not a published seat price that implies product maturity we have not earned.
