This page lists note-worthy classes and data models.


The top-level package with the main class:

  • EnergyQuantified: The client class. Use this class to initialize the client with an API key and to access API operations.

There is also additional class available here:

  • RealtoConnection: An alternative client class for Realto users. Use this class to connect to the API via a Realto subscription.

Where the time series, period-based series and OHLC data models are implemented:

  • Timeseries: The time series data model. A time series is more or less a series of values. There are three different value types:

  • TimeseriesList: A list of time series objects.

  • Periodseries: The period-based series data model. It has two different period types:

  • OHLC: A data class for a single OHLC. OHLC objects has a reference to:

    • Product: A description of a traded product (future contract).

  • OHLCList: A list of OHLC data objects.

  • SRMC: The server response from an short-run marginal cost (SRMC) calculation. It has multiple attributes, most are defined and used elsewhere. But it has one that is specific for SRMC:

    • SRMCOptions: A data class holding all factors used in an SRMC calculation.


Metadata classes are data classes with constants, such as enumerators. There are quite many classes in energyquantified.metadata:

  • These two enumerators are useful for aggregation:

    • Aggregation: Aggregetion methods such as mean, max, min, and so forth.

    • Filter: Enumerator of filters for electricity futures products such as base, peak.

  • Area: Representing a price area (or country). An area has a set of exchange Border with some capacity Allocation.

  • Curve: The identifier of any data series on Energy Quantified. Curves have a CurveType to define its storage types (time series, instance, period-based, OHLC) and DataType for its data type (forecast, normal, actual, etc.)

  • Instance: The identifier of any instance (forecasts, mostly).

  • Place: An identifier of anything with a geographical location, such as a powerplant, a large consumer, a location on a river. See PlaceType for all types.

  • OHLCField: Enumerator of fields in OHLC data objects.

  • ContractPeriod: Enumerator of contract periods for OHLC data objects. Typically week, month, quarter, year.


Date and time utilities.

  • Resolution: A combination of a frequency and a time zone. It has utility methods for stepping forward and backward in a given interval.

  • Frequency: Enumerator of supported frequencies on Energy Quantified. Mostly used for aggregations and in combination with resolutions.

  • Commonly used time zones in the European power markets:

    • UTC – Universal Time

    • CET – Central European Time

    • EET – Eastern European Time

    • WET – Western European Time

    • TRT – Turkish Time

  • local_tz(): Get your the local time zone on your workstation.

  • Useful functions to get dates and date-times:

    • now(): Get a time zone aware date-time of the current time.

    • today(): Get a time zone aware date-time of the today at midnight.

    • to_timezone(): Convert a date-time to given time zone.

    • get_date(): Create a date with sensible defaults.

    • get_datetime(): Create a date-time with sensible defaults.


Most utilities are internals, but there is one public-facing class in utils:

  • Page: An immutable list with paging support. Typically used by the metadata APIs to browse “pages” when searching for curves and places.


All exceptions are defined in this package.
