Quick read: green means a useful reference exists for a stated scope; yellow means partial progress or public disclosure; red means no accepted open reference is listed yet. Problem titles open the GitHub source cards.

Examples and seed references

Start with these 23 tracked references. Some cards still need source or licence review.

Area Seed references What this illustrates
Battery revenue and trading ISEA Battery Revenue Index, GigaStorage Battery Trading Benchmark, enspired Portfolio Performance Benchmark, trading benchmark, and public commercial disclosure.
Forecasting OpenSTEF Reproducible forecasting method.
Market simulation ASSUME Agent-based market simulation.
Grid modelling PyPSA, LF Energy Power Grid Model Open modelling and grid-analysis infrastructure.
Demand response and flexibility OpenLEADR, FlexMeasures, OpenEMS Event, flexibility, and energy-management tooling.
MaStR and asset registries Official Marktstammdatenregister, open-MaStR, MaStR MCP Server, bundesAPI Marktstammdaten API, Marktstammdatenregister.dev Registry, dataset access, API description, and AI-facing interface.
Shared terminology Open Energy Ontology Shared vocabulary and schema work.
Open optimisation stack HiGHS, Pyomo, JuMP, Google OR-Tools, COIN-OR CBC, SCIP Energy-enabling infrastructure for reproducible optimisation.
Tool health and adoption Open Energy Modelling Tool Tracker Tool inventory, repository metrics, documentation links, and community-activity signals.
Source ledgers EP-702 and the source-ledger template Source, query, timestamp, licence, result count, hash, and caveats.

Open code, open data, public methodology, AI interfaces, reproducible benchmarks, and commercial disclosures can all help the energy transition, but they are not the same thing. Know a better source or a missing open reference? Open an issue or pull request.

Problem to reference Reference relationship

Status

  • Open: problem stated, no accepted open reference.
  • Partial: meaningful progress, but important gaps remain.
  • Reference available: useful public reference exists.
  • Solved for scope: open reference exists for a narrow stated scope.

Open-Solution Level

  • 0: no accepted open reference.
  • 3: public methodology.
  • 4: open code.
  • 5: reproducible benchmark.
  • 6: open reference infrastructure.

Evidence

  • A: open code, data, reproducible result, independent review.
  • B: open code, documented method, sample data.
  • C: public method or figures, limited reproducibility.
  • D: public claim or unclear detail.
