<p>The markets operated by OTE a.s. are experiencing another very successful period after the record year 2024. In the first half of this year, almost 15.9 terawatt hours of electricity were traded on them. This is a third more than in the same period last year and so far the most in the history of the company\'s operations. Compared to the previous year, there was also an increase in the number of hours with a negative or zero price.</p> <p><br />The energy market operator OTE runs several types of electricity markets – the daily market, the intraday market, and since last summer it has also introduced intraday auctions. Thanks to this wide range of tools, it allows merchants to react very effectively to price fluctuations and also to optimize their purchases according to current consumption. This is very beneficial for them, especially at a time when extreme price fluctuations are increasingly common in (not only short-term) markets.</p> <p><br />"Interest in our products is still growing, and we can see it in the current figures. If nothing changes in the trend, we will already have a second record year in a row," says OTE Deputy Chairman of the Board of Directors Igor Chemišinec. "Along with the growing volume, we also see an increasing number of hours with a negative or zero price on the daily electricity market, so that already in the first half of the year, the number of hours with a negative or zero price reaches approx. 69 percent of the entire year 2024, a similar trend is also on the intraday electricity market," he adds.</p> <hr /> <p>More information including charts can be found in the attached press release <a data-val="6d8797b4238143e49c3bdc88d46db79c" href="https://www.ote-cr.cz/en/about-ote/ote-news/press-release250703_record-trading.pdf" data-linktype="internal">here</a>.</p>

<p>Although the test results confirmed the overall readiness of the project, the Market Coupling Steering Committee decided, <strong>due to non-technical readiness of some Parties, on the postponement of the project go-live of 15-Minute Market Time Unit (MTU) in SDAC from 11 June 2025 to 30 September 2025 (delivery date 1 October 2025).</strong> The updated detailed planning will be shared at the upcoming Market Coupling Consultive Group (MCCG) and Market Stakeholder Committee (MESC) meetings on 2 June 2025 and 3 July 2025, respectively.</p> <p>The company OTE, a.s., the nominated market operator (NEMO) in the Czech Republic, along with several other NEMOs, confirmed their full individual readiness to meet the planned go-live date of 11 June 2025, based on positive results from testing of both local and central systems.

<p>QUENT ApS has been registered in the central system OTE as a balance responsible party with access to the short-term power markets organized by OTE with effect from 15th May 2025. Currently the short-term power markets have 157 members and the short-term gas market has 145 members.</p>

<p style="text-align: justify;"><strong>It has been almost 20 years since every customer of electricity can choose their supplier. In the gas market, this option has been in place for 18 years. Functioning open energy markets, both in the Czech Republic and within the framework of international cooperation, enable consumers to freely choose a supplier, and thus better conditions for consumers, not only from the point of view of commodity prices themselves, but also of additional accompanying services. Also for this reason, there is vigorous competition in the field of energy supplies in the Czech Republic.</strong></p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">As can be seen from the statistical data of the market operator, which administers supplier changes in the Czech Republic, interest in changing energy suppliers has not abated even in 2024. Last year, 579,344 customers decided to change their electricity supplier, and a total of 204,696 customers decided to change their gas supplier. Thus, interest in changing electricity and gas suppliers is still at high levels. In the gas market, this is a more than twenty percent increase in changes compared to 2023, when 171,306 supplier changes took place.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;">Customers change suppliers for many reasons, whether due to the end of fixed-term contracts, price developments on the electricity market or gas market, or because of additional services offered beyond the scope of electricity or gas supply, or due to generally better information about the market situation. The data show that last year, customers most often switched to larger suppliers, such as ČEZ Prodej, PRE and E.ON.  However, the majority of supplier changes traditionally take place at the beginning of January, but as can be seen from OTE\'s statistics, customers\' efforts to change their supplier can also be seen in the following months. Most customers switched suppliers in 2021, which was marked by the onset of the energy crisis. At that time, however, the changes were mainly influenced by the collapse of some suppliers.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><em>"The results of the statistics for the past year show that the electricity and gas supply market in the Czech Republic is functioning. Customers have learned to navigate the market environment, they monitor price developments and the associated various price offers from which they choose the most advantageous. We are happy to help with this, both from the point of view of the administration of the entire process of changing suppliers, and also by organizing short-term markets that provide price signals",</em> says Michal Puchel, chairman of the company\'s board of directors OTE, a.s.</p> <p style="text-align: justify;"> </p> <p style="text-align: justify;"><em>"The electricity market in the Czech Republic is open to all consumers of electricity and gas. Each of them can choose a supplier according to their decision. I am pleased that the market operator and its system smoothly processes these transitions between suppliers, regardless of the reason for the change of supplier, the situation on the electricity market and the gas market, and overall thus contributes to the development of the energy industry as a whole,"</em> adds Igor Chemišinec, deputy chairman of the OTE board of directors.</p> <hr /> <p style="text-align: justify;">For more information, including charts, please see the attached press release <a data-val="d9bee46534b449b4884da87f030e4e36" href="https://www.ote-cr.cz/en/about-ote/ote-news/tz_202507_ote-market-shares-en.pdf" data-linktype="internal">here</a>.</p>
