Four forces are compounding at once — and they outrun both the spreadsheet and past experience.
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.
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.
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.
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.
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.
What changes on bid day, in IC, in lender Q&A — measured in hours saved and risk made visible.
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. |
Each answers a specific question a bid team, IC, or lender will actually ask — and each runs from the same underlying model.
Independent re-run per excursion → tornado chart ranked by IRR swing.
Monte Carlo probability-weighted combinations → IRR distribution + P10 / P50 / P90 S-curve.
Resource / CUF distributions propagated to an IRR exposure band.
Binary-search per input plus a combination solver for the closing gap.
Fast payback screen, then full IRR on the shortlist. Ranked, saved.
Degradation- and DSCR-aware search → optimal year and MW per site.
Sequential re-compute per changed input → IRR bridge by category.
Full input diff, field-by-field, grouped by type.
Perform every analysis a committee expects — faster, and with a reliability that spreadsheet-based models cannot match.
It slots into the workflow, tools and controls you already trust — and everything stays yours.
Full financial statement as live formulas wired between cells — not flattened values. Trace every number to its source.
Every input change tracked and registered. See who changed what and when; recover prior values.
Attach the PPA clause, lender term sheet, EPC contract or report to each input. Audit-ready.
Add, name and manage your own cost items, fund types or compliance rules — no fixed template.
Save incomplete models mid-build; the engine validates only when you run.
Import from Excel, clone any scenario, or reuse stored assumptions. Minutes, not days.
No cloud dependency. Every calc and term sheet stays on your machine. Confidential by default.
Generate an IC paper, lender submission or board pack — each built for its audience — in a single click.
No cloud, no transmission, no third-party access — confidentiality is the default, not a setting you switch on.
Nitch runs entirely on your own machine — no cloud service, no account, no model uploaded anywhere to be computed.
PPAs, tariffs, capital structures and term sheets stay local. No deal detail is ever sent to us or to any third party.
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.
It clears the confidentiality bar for deal-sensitive work out of the box — nothing for security or compliance to flag before you can start.
For work this sensitive, the safest place for your data is the one machine it never leaves.
Every formula stays on the surface, like an open workbook — but the load-bearing logic is protected, not editable by accident.
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.
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.
Place Solar, Wind, BESS, PSP, substation and delivery-point nodes. Connect fund sources and offtakes.
Technical, capex, opex, contract, compliance and finance — 25+ widget types for every input shape.
DP-based optimiser or heuristic rules decide charge, hold, discharge — per BESS, per interval, per offtake.
CAPEX phasing, IDC, DSRA sizing, debt sculpting to a DSCR floor, tax, CFADS, equity FCFE, IRR.
Sensitivity, risk, waterfall, capacity, repowering, inverse — all reusing the same base model.
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.
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.
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.
Walk the same pipeline Nitch runs — topology, assumptions, dispatch, sculpting, results, analysis. Click any step to jump in.
Drop Solar, Wind, BESS, PSP, substation and delivery-point nodes onto a single-line diagram. Draw the evacuation lines between them. This is the model foundation — every node maps to a domain object the engine will solve for.
Fill in technical, capex, opex, contract, compliance and finance assumptions per entity. 25+ widget types cover every input shape — from single values to hourly generation matrices, tariff bands with escalation slopes, and DSCR sculpting targets.
For each interval, the DP optimiser — or your own heuristic rules — decides whether the battery charges, holds or discharges. Grade tiers, compliance windows and market limits are enforced natively, deal by deal.
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.
Equity IRR, Project IRR, DSCR, LLCR, PLCR, LCOE, capital structure and cash-flow charts — all reachable from a single panel. Every metric is a node in the dependency graph, one click away from the inputs that built it.
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.
Bring a live deal — or one we've prepared. In one session we model it end to end and hand you the file. No slideware, no follow-up commitment.
Tell us about the project — a hybrid, a storage-shaped offtake, a repowering — and we'll set up a working session that fits.
