The market operator informs the market participants about the update of the technical documentation necessary for the implementation of 15-min. imbalance settlement and trading periods, namely:

• XSD templates 2.0 v7  (XML specification - markets, intraday auctions, imbalance settlement, financial security - which are valid instead of actual production templates in case of changes against the production environment);
• WSDL templates 2.0 v7 for automatic communication.

In addition, documents describing the further outlook for changes were published, namely the OTE-EDC Communication with impacts on market participants and Anticipated legislative changes as of July 1, 2024. Relevant updated documents related to these documents will be published at the turn of April/May 2024. The implementation of these changes to the OTE SANBOX-15min testing environment will take place in the second half of May 2024.

Updated versions of documents related to testing of 15-min. imbalance settlement and trading periods are available at https://www.ote-cr.cz/en/documentation/electricity-documentation/documentation-for-sandbox-with-15-min-period?set_language=en.

We kindly request all market participants to monitor continuously the updates published on the website of OTE, a.s.
