In the first half-year of 2021, our participants have traded 20,936 MWh on Ex-post (An increase of 26.67% compared to period Q3 & Q4 2020). In total 5846 ex-post trades (An increase of 13.74% compared to Q3 & Q4 2020) have been traded.

The participants have done 5846 trades and they have saved in total €1,646,285 on their imbalance costs. Which is equivalent to an average of 78.63 €/MWh imbalance.

We still got 3755 (sum of Buy & Sell orders) orders worth 33819.35 MWh of Ex-post orders open for trading (A decrease of 28.5% compared to Q3 and Q4 of 2020). On 90.75% of the regulation state 2 PTE’s, published by TenneT, we had orders quoted. If we look at the price disagreements at expiration (D+1 9:30) where a price difference between the highest buy and lowest sell order was less than 1 euro, a possible 6971.03 MWh could have been traded more if an agreement was reached.

So the opportunities for the market to save more on the imbalance costs are still there and can be leveraged.
