Upload supplier files

Drag & drop here supplier files input XXX.xlsx

You can upload several supplier files. Expected format: the embedded template, Input sheet, data in column C.

Use the template if a colleague needs a blank supplier input file.

Assumptions taken from your Excel model

The calculation engine includes:

  • Average DC RTE, AC RTE and Overall RTE
  • Usable Energy at POI, Net Discharge POI and auxiliary consumption
  • Capacity retention, Guaranteed capacity margin, EOL SOH
  • Footprint: equivalent area / container, area / MWh and area / MW
  • Automatic scoring with editable weights
MVP: commercial and supplier-risk criteria are initialized at 5/10 and can be edited in the Scoring tab.

Global ranking

Best performer by KPI

Comparison

Supplier product benchmark KPIs used for comparison / scoring

These KPIs are normalised at product level and are intended to remain comparable independently from one specific project architecture.

Project-specific / submitted architecture data information only

These values depend on the submitted project sizing or on the input file architecture. They are displayed for traceability, but they are not used in the Supplier Product Benchmark score.

Scoring

Scoring scope: only Supplier Product Benchmark criteria are used in the weighted score. Project-specific values do not affect the rank.

Supplier benchmark scoring criteria score impact

Project view: the data below is project-specific or architecture-dependent and is shown for review only. It is not scored in the supplier benchmark ranking.

Project-specific reference data not scored

Criteria Settings

Automatic criteria are recalculated after each change. Manual criteria can be adjusted directly by supplier in the scoring table.

Footprint

Supplier footprint benchmark normalised

Supplier mode compares product-level footprint: container footprint, MWh/container and m²/MWh.

Project-specific footprint submitted architecture

Project mode shows total area and area/MW based on submitted number of containers and rated power.

Project history

Local browser storage for this MVP. For real multi-user access, this layer should be connected to a PostgreSQL/Supabase/Azure SQL database.

Comparison across saved projects

Compares saved supplier-comparison campaigns: number of suppliers, best score, best supplier, average RTE and average footprint.

Supplier database

Automatically consolidates suppliers already loaded in saved projects. Useful as a preliminary supplier benchmark and prequalification database.

Multi-user access — local prototype mode

This mode simulates roles in the browser. Real security requires a backend with authentication, project-level permissions and a server database.

Mapping Excel

Supplier files are read using this mapping. You can update the code if the template evolves.

Calculation notes

The formulas are aligned with the logic of your performance table file.

  • Overall RTE = average DC RTE over the common comparison horizon × AC losses chain
  • Net Discharge POI = Usable POI MWh - (Total Aux kWh/cycle / 1000).
  • Auxiliary consumptions are treated as kWh/cycle as provided by suppliers.
  • Aux / Net (kWh/MWh) = Total Aux kWh / Net Discharge MWh.
  • Aux / Net (%) = Total Aux kWh / (Net Discharge MWh × 1000) × 100.
  • Supplier benchmark does not use project-dependent capacity retention or guaranteed capacity margin. It uses SOH at common horizon, DC RTE, auxiliary kWh/MWh, MWh/container and m²/MWh.
  • Guaranteed capacity margin = Net Discharge POI / Guaranteed Capacity - 1 is shown only in project-specific views.
  • Automatic scoring = linear normalization: best = 10, worst = 1
In a later version, an admin mapping page can be added without touching the code.
