Integrated India energy data.

Modeler uses India Energy Atlas records for network, system, market, weather and forecast inputs.

  1. National data coverage

    State and national demand, generation, fuel mix, weather and network inputs are available in one catalogue.

  2. Market and carbon series

    IEX market products, price areas, renewable markets and hourly carbon intensity are available for studies.

  3. Provenance and validation

    Source, confidence, data status, forecast accuracy and calibration fields remain available for review.

Does Modeler run in the browser?

Yes. Modeler provides a browser-based workspace with managed cloud compute. Models, scenarios, runs and results are stored in the workspace.

Which India datasets are built in?

India Energy Atlas supplies network assets, state and national demand, generation, fuel mix, IEX market, weather and forecast datasets. Source, coverage and data-status fields are retained where available.

Is programming required?

No. The same model is available through graphical controls, GridAI and code.

What can the agent change?

GridAI can inspect a model, prepare typed edits, create scenarios, run supported tools and explain results. Changes remain available for review.

How is Modeler priced?

Modeler compute is available through eligible India Energy Atlas plans. Current prices and compute entitlements are listed on the pricing page.
