BMRS Datasets

Maximum Delivery Volume (MDV) stream

This endpoint provides Maximum Delivery Volume data received from NGESO.

Maximum Delivery Volume is the maximum number of MWh of Offer (or Bid), that a particular BM Unit may deliver within the associated Maximum Delivery Period.

By default, the from and to parameters filter the data by time inclusively. If the settlementPeriodFrom or settlementPeriodTo parameters are provided, the corresponding from or to parameter instead filters on settlement date, allowing for searching by a combination of time and/or settlement date & settlement period. Note: When filtering via settlement date, from/to are treated as Dates only, with the time being ignored. For example, 2022-06-01T00:00Z and 2022-06-01T11:11Z are both treated as the settlement date 2022-06-01.

All Dates and DateTimes should be expressed as defined within <a href="https://datatracker.ietf.org/doc/html/rfc3339#section-5.6" target="_blank">RFC 3339</a>.

Some examples of date parameter combinations are shown below.

Filtering from start time to start time:

/datasets/MDV/stream?from=2022-06-01T00:00Z&to=2022-07-01T00:00Z

Filtering from start time to settlement date and period:

/datasets/MDV/stream?from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodTo=1

Filtering from settlement date and period to start time:

/datasets/MDV/stream?from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodFrom=1

Filtering from settlement date and period to settlement date and period:

/datasets/MDV/stream?from=2022-06-01T00:00Z&to=2022-07-01T00:00Z&settlementPeriodFrom=1&settlementPeriodTo=1

This endpoint has an optimised JSON payload and is aimed at frequent requests for MDV data.
