Attention of market participants: Maintenance plan for the software complex 16.06.2026

16.06.2026

JSC �Market Operator� hereby informs that, in accordance with clause 1.5.6 of the Day-Ahead and Intraday Market Rules, scheduled maintenance of the market operator�s software system XMtrade�/PXS will be carried out on 16.06.2026 from 19:15 to 22:00. As a result, access to the system will be restricted, and interruptions in the operation of the JSC �Market Operator� website may occur.

During the maintenance of the XMtrade�/PXS software system, the following changes will be implemented:

the mechanism for submitting DAM orders (hourly, simple block, profiled block, and linked block orders) via the web interface has been improved for cases where a DAM/IDM participant, in a DAM buy/sell order, wishes to specify identical volumes and/or prices for a certain number of settlement periods (a feature enabling copying of parameters to other hours has been implemented);
a new functionality has been added to inform DAM/IDM participants, during IDM order submission via file import, about the presence of their own opposite-direction order(s) in the order book that may be mutually accepted.

Please note that gate closure for the Intraday Market for settlement periods 21�22; 22�23; 23�24 (delivery day 16.06.2026) will take place on 16.06.2026 at 19:00.

We kindly ask for your understanding regarding the efforts of the Market Operator team to ensure the uninterrupted organization of electricity trading.
