<p style="text-align: justify;"><strong>OTE, a.s. and the Ministry of Industry and Trade Announce the Introduction of a 15-minute Settlement and Trading Period in the Czech RepublicOTE, a.s. (OTE, Marcet Operator) and the Ministry of Industry and Trade (\'MPO\') are pleased to announce the introduction of a 15-minute settlement and trading period in the Czech Republic from the day of delivery, July 1, 2024. This significant step represents an important milestone in the transition of the energy market and at the same time in strengthening the development of international cross-border trading.</strong></p> <hr /> <p style="text-align: justify;">Shortening the settlement and trading period from 60 minutes to 15 minutes brings a number of benefits, including increased flexibility that allows market participants to better respond to changes in supply and demand, which contributes to the optimization of trading strategies, furthermore accurate analysis of electricity consumption and production, and improved integration of renewable sources energy. The introduction of a shortened settlement and trading period is also fully in line with European legislation and standards aimed at harmonizing energy markets across Europe. Along with this change, the market operator innovated market platforms and expanded trading opportunities in the short-term electricity markets it organizes by introducing trading through pan-European intraday auctions. Trading on these platforms makes it possible to develop business strategies and bring additional benefits to end customers on the electricity market in the Czech Republic.<br /><br />This is one of the biggest changes in the electricity market in the Czech Republic since the beginning of the successful liberalization of the electricity market in 2005, when for the first time the end customer could choose his electricity supplier. The market operator devoted more than three years of intensive work to this important change, when, thanks to the new technical solution and the high expertise of all employees, he managed to successfully implement this change in the key processes of the electric power industry and at the same time provided all the support to the electricity market participants to prepare for this change. This change had similar effects for market participants, who not only had to adjust their systems, but also had to make related adjustments to the data they exchange within the market with the market operator and through its central information system.<br /><br />Mr. Michal Puchel, Chairman of the Board of Directors of OTE, a.s., stated: "The successful introduction of the 15-minute settlement and trading period is the result not only of our intensive cooperation, but also of the preparations of all parties involved. This step will allow us to respond better to dynamic changes in the market and contribute to greater stability and efficiency of the energy system. We are proud to bring innovations that will have a positive impact on the entire market and end consumers."<br />"This is another in a series of measures aimed at modernizing our power engineering. Electricity production from renewable energy sources such as solar or wind changes more frequently than we are used to with other<br />sources. Shortening the billing and trading period responds to this and will enable both market participants and end consumers to respond more effectively to market developments. The measure will therefore give customers the opportunity to reduce their electricity expenses," added Mr. Jozef Síkela, Minister of Industry and Trade.<br /><br />The market operator would like to thank all market participants for their cooperation and active involvement during the preparation period. Your participation in webinars and workshops and suggestions for upcoming changes were among the key factors in the successful implementation of this project.<br />After the introduction of the 15-minute settlement and trading period, OTE will continue to provide all necessary support to market participants in their activities on the electricity and gas market.</p> <hr /> <p style="text-align: center;">The press release can be downloaded in PDF format <a data-val="9c975ae23b2943bdb1a1c28ede86cf03" href="https://www.ote-cr.cz/en/about-ote/ote-news/20240706_press-release_15min-settlement-and-trading-period-in-cr.pdf" data-linktype="internal">here</a>.</p>

<p><strong><span style="font-size: 10.5pt; font-family: Roboto;">ELGAS Energy, s.r.o. </span></strong><span style="font-size: 10.5pt; font-family: Roboto;">was terminated in the central system OTE as a balance responsible party in power and gas markets as of 3<span style="color: black;">0</span>th <span style="color: black;">June</span> 2024.

<p style="text-align: justify;">On June 25, with the delivery day on June 26, local technical difficulties on the side of EPEX SPOT led to the partial decoupling of the Single Day-Ahead Market Coupling (‘SDAC’). Despite these technical difficulties, the day-ahead electricity market in the Czech Republic, organized by OTE, remained coupled with other markets in the Core and EU regions, except for Denmark, Estonia, Finland, Latvia, Lithuania, Norway, and Sweden. As a result, the order books (‘OBKs’) of EPEX SPOT (for the CORE, Nordic, and Baltic regions) and EMCO – Nordpool (for the Nordic and Baltic regions only) were not included in the SDAC coupling process.</p> <p style="text-align: justify;">The incident was caused by technical difficulties on the side of EPEX SPOT, which prevented the submission of the order book by EPEX SPOT before the deadline set in the binding procedure, resulting in the partial decoupling of the single day-ahead market coupling. This partial decoupling was declared in accordance with the relevant operational procedures at 13:05 CEST. In the CORE region, cross-border capacities were successfully allocated fully in accordance with the regional procedure, without any limitations within the implicit trading among the remaining nominated electricity market operators. Therefore, it was not necessary to activate backup mechanisms for so-called “shadow” auctions in the CORE region.</p> <p style="text-align: justify;">The Nordic and Baltic capacity calculation regions were decoupled in accordance with regional backup procedures, which prioritized market coupling within the respective regions over the single market coupling. Despite these challenging events, the SDAC coupling process was completed at 14:09 with the publication of the results in the coupled markets, including the Czech market.</p> <p style="text-align: justify;">On the following day, June 26, with the delivery day on June 27, the single day-ahead market was run successfully in fully coupled mode with the involvement of all bidding zones and order books.</p> <p style="text-align: justify;">On the same day, June 25, 2024, earlier in the day, the same technical issue on the side of EPEX SPOT also led to the cancellation of the 3rd Intraday Auction (‘IDA3’) at 10:00 CEST for the delivery day on June 25 and subsequently to the organization of the first Intraday Auction for the delivery day on June 26 (‘IDA1’ at 15:00 CEST) without the Nordic and Baltic capacity calculation regions and without the EPEX SPOT order book. Based on the information regarding the resolution of the technical issue by EPEX SPOT, the second Intraday Auction for the delivery day on June 26 (‘IDA2’ at 22:00 CEST) was successfully performed in fully coupled mode.</p> <p style="text-align: justify;">The Market Coupling Steering Committee (‘MCSC’) initiated a detailed investigation, with conclusions expected to be published within a month in the final incident report. However, it can already be emphasized that the central systems and the common algorithm were fully operational throughout the incident, and the cause was local issues of one of the nominated electricity market operators within the coupled single day-ahead and intraday electricity market.</p> <hr /> <p style="text-align: justify;">Further details on these incidents are provided in the official report of the MCSC, available <a href="https://www.nemo-committee.eu/assets/files/mcsc-initiated-an-in-depth-investigation-of-the-partial-decoupling-of-sdac-and-cancellation-of-sidc-ida3-taking-place-on-25-of-june-(trading-date).pdf">here</a>.</p>

<p><strong>On May 29, 2024, OTE, a.s., (hereafter also the market operator, OTE) became the 5th member of the Gas Scheme Group (GSG), within "Association of Issuing Bodies" (AIB), the European Association of issuers of Guarantees of origin. This membership will enable the market operator to make available to traders the possibility of international transfer of biomethane guarantees of origin within the framework of the AIB, which will thus suitably complement the already ongoing international transfer of electricity guarantees of origin.</strong></p> <hr /> <p>At the May meeting of the AIB (<a href="http://www.aib-net.org">www.aib-net.org</a>) in Riga/Latvia, OTE, as the issuer of guarantees of origin in the Czech Republic, became another member of the group for guarantees of origin in the gas industry. After the completion of all necessary processes and technical tests in the IT system of the market operator during June, the international transfer of biomethane guarantees of origin issued according to the rules and standards of the European Energy Certificate System (EECS) with other Gas Scheme Group members over the AIB hub will be enabled thanks to this membership. To date, GSG members within the AIB association are issuing entities in Austria, Spain, Latvia and Finland. The involvement of other countries in the GSG is being prepared.</p> <p>The expansion of options for export/import of guarantees of origin for electricity to export/import of guarantees of origin for biomethane is made possible thanks to OTE\'s international activities in the area of guarantees of origin, especially thanks to OTE\'s membership in the AIB association. By engaging in cooperation in the framework of transfer of guarantees of origin for electricity and biomethane, OTE responds to the needs of traders to ensure not only domestic but also international transfer of these guarantees of origin, and thus fulfills the objectives set by Directive (EU) 2018/2001 of the European Parliament and of the Council of 11 December 2018 on the promotion of the use of energy from renewable sources in the area of guarantees of origin. Currently, 30 EU and non-EU countries are associated with the AIB association.</p> <p>"<em>We are proud to have been a member of the AIB association for many years, and now, as part of this association, we have expanded our activities in the field of guarantees of origin for biomethane to include the possibility of international transfers. It is the result of long-term full-fledged cooperation of our company within the framework of international projects and activities and the maximum work commitment of Martina Gabriel and her team</em>", says Michal Puchel, Chairman of the Board of Directors of OTE, a.s.</p> <p>Bc.
