The Financing Challenge

The question every deal team is asking.

How do we shorten the path from concept to investment decision — while deepening our analytical and risk appreciation as storage and offtake commitments become complex?
— The gap Nitch is built to close
A Compounding Challenge

Four pressures reshaping deal modelling.

Four forces are compounding at once — and they outrun both the spreadsheet and past experience.

Storage and shaped offtake

Revenue and returns depend on when the battery charges, holds and discharges — and on the hybrid capacity mix behind it. Dispatch and capacity optimization become critical to valuation.

Hybrids, assessed hour by hour

Hybrid plants assessed at hourly or sub-hourly resolution multiply the inputs and the computation. Parameter counts balloon; the model becomes hard to build, run, and keep consistent.

Risk without precedent

This complexity carries exposures your past deals never met — risk that experience alone cannot size, and that has to be quantified rather than judged by feel.

More projects, evolving terms

Project volume keeps climbing while contract terms keep shifting — new offtake shapes, tariff mechanics and compliance rules deal to deal. Every change means re-modelling, with less time each cycle.

In short

Each pressure is real and compounding — and none is answered by a better spreadsheet or more experience alone. This is the gap Nitch is built to close.

Where This Gets You

Outcomes at the point of decision.

What changes on bid day, in IC, in lender Q&A — measured in hours saved and risk made visible.

1
Answers on demand
Every figure traces to an input you can name — so the committee's "how did you get this?" has an immediate answer.
2
Downside made visible
You put a P90 on the table, not just a base case — the risk-adjusted range a lender expects before committing.
3
A week recovered per deal
One model that re-runs in minutes replaces five linked spreadsheets and roughly a week of analyst time.
4
Confidential and consistent
Deal data never leaves your machine, and the file you model is the file you present — no version drift.
Task by Task

Where Nitch actually shows up.

The concrete modelling tasks a deal team runs, and what changes in each.

Modelling task Typical spreadsheet workflow With Nitch
Set up a hybrid Solar + BESS project Different types of projects and their input structure assembled by hand; days of prep before the first run. Drag-and-drop topology, pick fund and offtake, configure once. Ready to run.
Model a shaped or dispatchable offtake Frequent remodelling for each case or offtake term change. Offtake grades and hourly dispatch are handled natively — no bespoke wiring per deal.
Size debt to a DSCR floor Iterative goal-seek scenario by scenario, tenure by tenure. Sculpting solver enforces the floor in one run; results carry through.
Rerun after a tariff or capex change Trace the change through every linked sheet; re-verify tie-outs. Edit the input, re-run. Dependency graph flags every downstream effect.
Capacity sizing Requires exhaustive scenario runs or an external optimiser to find optimal capacities. Every change in cost structure shifts the answer. Built-in optimiser finds the optimal capacity mix with limited setup. Easy to re-trigger after any input change.
Sensitivity across 8–10 inputs Nested data tables or manual excursions. Pick inputs, set ranges, get a ranked tornado — minutes.
Probability-weighted risk analysis Requires a paid add-in or external Monte Carlo tool. Built-in scenario expansion with P10 / P50 / P90 distribution.
Trace an output metric to its inputs Follow precedents cell by cell across linked workbooks. Cascade view: any metric → its formula → the inputs that built it.
Produce a lender or IC pack Copy-paste from Excel, reformat by hand, verify figures line up. One-click PDF, audience-tuned (IC / lender / board) from the same run.
Analytics

Eight analysis tools, one workflow.

Each answers a specific question a bid team, IC, or lender will actually ask — and each runs from the same underlying model.

Sensitivity

Which assumptions move IRR most?

Independent re-run per excursion → tornado chart ranked by IRR swing.

Risk Analysis

What risk is the project carrying?

Monte Carlo probability-weighted combinations → IRR distribution + P10 / P50 / P90 S-curve.

Generation Uncertainty

How does RE resource variability hit IRR?

Resource / CUF distributions propagated to an IRR exposure band.

Inverse Modeling

What input hits target IRR?

Binary-search per input plus a combination solver for the closing gap.

Capacity Optimiser

What capacity mix maximises returns?

Fast payback screen, then full IRR on the shortlist. Ranked, saved.

Repowering Optimiser

Should I augment mid-life?

Degradation- and DSCR-aware search → optimal year and MW per site.

Waterfall Analysis

How does IRR change between scenarios?

Sequential re-compute per changed input → IRR bridge by category.

Scenario Comparison

What differs between two scenarios?

Full input diff, field-by-field, grouped by type.

Net effect

Perform every analysis a committee expects — faster, and with a reliability that spreadsheet-based models cannot match.

Low-Risk to Adopt

Designed to fit existing workflows.

It slots into the workflow, tools and controls you already trust — and everything stays yours.

Excel export, linked formulas

Full financial statement as live formulas wired between cells — not flattened values. Trace every number to its source.

History management

Every input change tracked and registered. See who changed what and when; recover prior values.

Source pinning

Attach the PPA clause, lender term sheet, EPC contract or report to each input. Audit-ready.

Custom assumption setup

Add, name and manage your own cost items, fund types or compliance rules — no fixed template.

Work-in-progress models

Save incomplete models mid-build; the engine validates only when you run.

Fast model creation

Import from Excel, clone any scenario, or reuse stored assumptions. Minutes, not days.

Completely offline

No cloud dependency. Every calc and term sheet stays on your machine. Confidential by default.

One-click PDF reports

Generate an IC paper, lender submission or board pack — each built for its audience — in a single click.

Offline & Confidential

Deal-sensitive data never leaves your machine.

No cloud, no transmission, no third-party access — confidentiality is the default, not a setting you switch on.

Completely offline

Nitch runs entirely on your own machine — no cloud service, no account, no model uploaded anywhere to be computed.

Nothing crosses the network

PPAs, tariffs, capital structures and term sheets stay local. No deal detail is ever sent to us or to any third party.

Confidential by default

No shared tenancy, no vendor access to your data, no breach of someone else's servers to expose you. There is simply nothing to leak.

An easy yes for IT

It clears the confidentiality bar for deal-sensitive work out of the box — nothing for security or compliance to flag before you can start.

In short

For work this sensitive, the safest place for your data is the one machine it never leaves.

The Black-Box Question

Visible formulas, protected logic.

Every formula stays on the surface, like an open workbook — but the load-bearing logic is protected, not editable by accident.

WHERE EXCEL GENUINELY WINS

The white-box gold standard

  • Click any cell, read its formula, walk precedents to first principles — total white-box visibility.
  • Nothing hidden, no tool to learn: the model's logic sits literally on the surface.
  • The gold standard for "show me exactly how this number was built."
  • Formulas and linkages can be changed or added as the user wishes.
WHAT NITCH OFFERS INSTEAD

Traceable without being fragile

  • Dependency graph — trace any output metric down to the inputs that built it, formula by formula with live values.
  • Source pinning — every input can cite its term sheet, PPA clause or source document.
  • History — every change logged with when and the prior value. Version control that isn't filenames and memory.
  • Excel model export — the full financial assembly (P&L, sculpt, DSCR, CFADS, tax, IRR) stays formula-traceable in the tool your lender already uses.
  • Enforced integrity — load-bearing formulas can't be silently overwritten, so the sculpt keeps holding DSCR and the balance sheet keeps tying.
The honest limit

Two stages — the DP dispatch optimiser and the DSCR sculpt — run in-engine, not as cells. Around them: heuristic dispatch exports as live formulas, the dependency graph traces every engine metric back to its inputs, and the financial assembly stays fully formula-traceable.

How It Works

Five phases, one calculation.

Nitch runs a single, coherent modelling pipeline — from topology setup, through hourly dispatch, to sculpted debt and IRR. Every analysis branch reuses the same engine.

01 · TOPOLOGY

Draw the deal

Place Solar, Wind, BESS, PSP, substation and delivery-point nodes. Connect fund sources and offtakes.

02 · ASSUMPTIONS

Configure inputs

Technical, capex, opex, contract, compliance and finance — 25+ widget types for every input shape.

03 · DISPATCH

Hourly optimiser

DP-based optimiser or heuristic rules decide charge, hold, discharge — per BESS, per interval, per offtake.

04 · FINANCIAL

Sculpt & solve

CAPEX phasing, IDC, DSRA sizing, debt sculpting to a DSCR floor, tax, CFADS, equity FCFE, IRR.

05 · ANALYSIS

Eight branches

Sensitivity, risk, waterfall, capacity, repowering, inverse — all reusing the same base model.

Dependency graph

Every metric — IRR, DSCR, CFADS, EBITDA — is a node in a directed graph. Click any output and cascade back to the inputs that produced it, with live values and formulas at each step.

Micro-calculation

Change a rate or an escalation and re-solve only the affected chain in a sandbox — no full dispatch rerun. The dirty-key resolver uses the runtime imprint of the last calculation.

Excel & PDF export

Live-formula workbooks (P&L, sculpt, DSCR, CFADS, IRR) and audience-tuned PDF packs (IC, lender, board) generated from the same run — configurable page size, native vector charts.

Interactive Tour

From topology to investment decision, in six steps.

Sculpt & solve

CAPEX phasing, IDC accrual, DSRA sizing, then debt sculpted to your DSCR floor. Tax, CFADS, equity FCFE and IRR fall out of the same run. Enterprise capital stacks with OCD, CCD, warrants and tax equity resolve here too.

  • Sculpting solver enforces DSCR floor in one pass

Stress and explore

Eight branches reuse the same base model: sensitivity, risk (Monte Carlo with P10/P50/P90), waterfall, capacity optimiser, repowering, inverse solve, generation uncertainty, scenario comparison. Every committee question — answered from one run.

  • Deep-copy sandbox — base model never mutated
  • Complex inputs trigger dispatch reruns; the rest re-solves fast
  • Tornado, distribution, waterfall, comparison — all exportable
