The Duck Curve is called the curve that simulates the shape of a duck, representing the Net Load curve, by subtracting the RES generation curve from the system Load curve.
The following graph shows:
Notes:
The Intraday Market includes Intraday Auctions (IDAs) and Continuous Intraday Trading (XBID).
The Integrated Scheduling (ISP) includes the solutions of ISP2 and ISP3 of IPTO, for the first twelve and the last twelve hours of each day respectively, close to real-time. Since no data is published by IPTO for the solution of the Real-Time Balancing Energy Market (RTBEM), which is the most approximate result of the actual real-time operation, the ISP was chosen to be depicted as the the closest to real-time solution.
IPTO, since 18.01.2024, publishes the estimated Energy Surplus within the ISP. The actual Energy Surplus in the real time may differ significantly from the estimated Energy Surplus in the above indicative schedule (ISP), and should be considered as an indicative estimation by IPTO close to real time.
For the Day Ahead Market and the Intraday Market, the net load of Crete, as a result of the electric demand of Crete minus the local electricity production from RES and thermal units, is added to the load of the system (Load DAM, Load Market),while for the Integrated Scheduling Process the power flow through the Crete-Peloponnese cable (VIRTUAL_CRETE of the ISP) is added to the load of the system (Load ISP), as Crete – until the start of operation of the Crete – Attica interconnection – is treated as a Small Interconnected System.
The Energy Surplus from ISP has negative values, as depicted in the settlement of the Integrated Scheduling Process implemented by IPTO.
