<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>

<p>Greenhouse gas emissions in the Czech Republic dropped by 13% in 2024 compared to 2023, according to data recorded in the European Union\'s single registry, which is administered by the Czech company OTE. The obligation to report their emissions applies to 5 aircraft operators and 147 companies operating 213 stationary installations that are part of the European Union Emissions Trading System (EU ETS) in the Czech Republic.</p> <p><br />These emissions for 2024 in the Czech Republic amounted to 40.9 million tonnes of CO2e, a year-on-year decrease of 13%. Therefore, a long-term downward trend in emissions produced in the Czech Republic continues, as shown by the figures in the following graph representing the EU ETS emissions of CO2, N2O and PFCs in the Czech Republic since 2005.</p> <p><img class="image-inline" style="display: block; margin-left: auto; margin-right: auto;" src="../../../cs/o-spolecnosti/zpravy_ote/povolenky.png" alt="" data-linktype="externalImage" data-scale="large" data-val="https://www.ote-cr.cz/cs/o-spolecnosti/zpravy_ote/povolenky.png" /></p> <p><strong>EU ETS emissions of CO2, N2O and PFCs in the Czech Republic</strong> (total, in tonnes of CO2 equivalent)<br />The obligation to monitor and report their emissions of greenhouse gases emitted into the air in the previous calendar year and subsequently surrender allowances in the amount corresponding to their emissions applies specifically to operators of installations for each installation, that has been issued a permit by the Ministry of the Environment to emit greenhouse gases into the air, and aircraft operators for each aircraft that has an operating license issued in the Czech Republic or falls under the administration of the Czech Republic according to the list of aircraft operators issued by the European Commission. The European Union\'s single registry is used to record emissions and allowances, and the national administrator of this registry is OTE.</p> <p><br />"The reduction in emissions in the Czech Republic last year was higher than the average reduction in Europe, which was 5%. This is due to a stronger industrial presence in the Czech economy as well as the Czech energy mix with a higher share of coal-fired power plants, which for economic reasons are used relatively less year-on-year. ", says Michal Puchel, Chairman of the Board of Directors.<br /><br />The EU ETS is the cornerstone of the EU\'s climate policy and its key instrument for reducing greenhouse gas emissions. It was the world\'s first carbon market and is still one of the largest. Reducing the amount of greenhouse gases produced by companies is an important part of environmental protection, particularly climate protection.</p> <p>Press release in PDF format <a data-val="8528f3068d5e4865a44c69c270391dcf" href="https://www.ote-cr.cz/en/about-ote/ote-news/20250411_press-release_emission-drop-again.pdf" data-linktype="internal">here</a>.</p> <p><img class="image-inline" src="https://ote-cr.cz/cs/o-spolecnosti/zpravy_ote/povolenky.png" alt="" data-linktype="externalImage" data-scale="large" data-val="https://ote-cr.cz/cs/o-spolecnosti/zpravy_ote/povolenky.png" /></p>

<p><strong>After the successful integration of the Czech intraday electricity market into the Single Intraday Coupling (SIDC) in 2019 and enabling trading in 15-minute trading periods on the Czech-Slovak, Czech-German, and Czech-Austrian cross-border interconnectors in 2024, the trading period was successfully switched to 15-minute for the last Czech-Polish interconnector on March 18, 2025. This was completed in the implementation wave that also included transition to 15-minute in Norway (all bidding zones), Portugal, Spain, and Poland. At the same time, the Romanian-Hungarian and Romanian-Bulgarian borders were integrated into the European Intraday Auctions (IDA).</strong></p> <p>The successful rollout of the 15-minute MTU across nearly all of Europe’s internal bidding zones and interconnectors marks a major milestone.
