System Imbalances at the source (BRP):

• Single marginal imbalance tariff since 01/01/2012
• Enhanced balancing publications: e.g. wind and solar forecastings
• Further market integration (NWE intraday, etc.)
• Etc.

Diversify assets providing balancing services:

• In 2013 - R1/R2 contracts revised to allow a variety of assets

6

• Load participating in supply of primary control (2013)
• Participation of aggregators in the supply of interruptible load (2013)
• RES as well as Storage

XB-synergies:

• BE participation to iGCC (imbalance netting with 6 countries incl. DE)
• Potential BE-NL XB synergies (with Tennet NL)
• Further investigations for iGCC evolutions
• Etc.
