Vocabulary

This page collects the core terms used throughout the Predico documentation and platform. Use it as a quick reference when reading the guides, the API docs, or the Terms of Use. Terms in bold elsewhere in the docs map back to the definitions below.

Term	Meaning
Market Owner	Owner of resources or a grid (e.g. wind farm owner, TSO) that funds forecasting sessions.
Program	A market owner's configured offering: which horizon categories it publishes, at which gate-closure hours, and its reward structure. Built on the platform's hourly sessions. See Programs.
Forecaster	Registered participant who submits forecasts and competes for rewards.
Market Session	A window during which Market Owners publish challenges and Forecasters submit forecasts.
Market Challenge	A single forecasting opportunity inside a session, with its own target variable, horizon and gate.
Gate Closure	Deadline after which no more submissions are accepted for a challenge (authoritative field: gate_closure).
Horizon Category	intraday, day-ahead (D+1), or extended (D+N). See Sessions & Challenges.
Forecast Variables	Currently quantiles Q10, Q50, Q90.
Ensemble Forecast	Aggregate forecast derived from all forecasters' submissions.
Settled measurement	The market owner's consolidated value for a timestamp, used to compute scores once the month is frozen.
Near-real-time measurement	A provisional value published minutes after the fact, replaced by the settled one on a later re-import. Not every resource has one.
Settlement freeze	The day of the following month after which a month's measurements no longer change (after day 6 for the current programs). The month's scores, and so its ranking, are locked on day 7 at the latest.
Control area	A TSO's balancing zone, identified by an ENTSO-E area code (e.g. 10YDE-VE-------2 for 50Hertz). A control-area target is the sum over every asset in that zone.
mFRR	Manual Frequency Restoration Reserve: balancing energy a TSO activates on request to correct imbalances, upward or downward. EDP's resources forecast Spain's net activated mFRR energy and its price. See EDP.
