Updates to the JAO website

Dear market participant,

To improve the user experience, JAO introduced a few layout and functionality updates to the JAO website.

1. 1. Using quick links, our users can now access important content directly from the Homepage.

2. 2. Group filters on the Export page has been enabled.

3.3. To achieve a faster selection of auction data we have also made some changes at the auction pages.

o A default date selection has been introduced on Intraday, Daily and Monthly horizons.

o Auction ID is automatically selected as long as only one round of auction is available.

o Possibility to switch directions by an arrow while keeping the previously selected date.

o Auction data window has been extended for day-ahead and intraday auctions.

We have made these updates by taking into account the valuable feedback provided on the annual JAO customer satisfaction survey.

Best regards,

JAO S.A.
