<div style="font-family: \'Segoe UI\'; font-size: 14px; font-style: normal; font-weight: 400; line-height: 20px;"> <p>In 2025, interest in Guarantees of Origin (GOs) increased significantly across electricity, biomethane and heat. Nuclear energy dominated issuance, accounting for 84% of all GOs, most of which were exported. Issuance from renewable sources continued to decline, yet consumption was primarily covered by renewable GOs, representing 88% of all cancellations, largely supported by growing imports.</p> <p>Biomethane recorded substantial growth in all categories, including the first-ever imports via the AIB Hub. Heat GOs saw strong growth as well, issued almost exclusively from renewable sources. No transactions were recorded for hydrogen in 2025.</p> <hr /> <div style="font-family: \'Segoe UI\'; font-size: 14px; font-style: normal; font-weight: 400; line-height: 20px;"> <div id="copilot-message-rdu" class="fai-CopilotMessage__content r1izxv8h ___7qar2c0 fcthzvy" dir="auto"> <div dir="auto"> <div class="___1vve6yh f22iagw f1vx9l62 f122n59 f3bhgqh f1mnxvew fly5x3f"> <div class="___j4vmuw0 f22iagw f1vx9l62 f1869bpl fly5x3f fbc6vix"> <div tabindex="-1" data-testid="loading-message" data-fui-focus-visible=""> <div> <div id="chatMessageResponse-rds" class="___1yop6mf f336tjw f9ijwd5 fz7g6wx fod5ikn f1s184ao"> <div class="___1j4t0a1 f1lmfglv f1abmfm4" dir="auto" data-testid="markdown-reply" data-message-type="Chat"> <div class="___stpibi0 f22iagw f1vx9l62 fk15e71 f1k953kz f137keqj f1rncccw f1stllg3 f1w4kmmc f1tric3v f10dk5ic fx8cdsv f16nlwsl f1eookvz fhjrts3 fqugt2f f10km5jb f18d18k8 f1v1vhmp f1hdmul3 f198vjnp f2dshw1 fjpjndq fnmj2pj ffrrb40 f1mon110 fhajzam fimndk6 fxv4dng fb1rn9k f59wlhv f1xmfh30 f18yf5o5 fmr6chf fw8qy2q ff161sd f1qr7t77 f1yyogn1 foogchg fp5872b f1tpb8gf f1hdgrc8 f1vatr43 frkxccd f9pdzkb f158oiaz ft5kggy f5l4ui7 f13j03li f18xdoka f8off4e f1go6zfc f128n2ra f1jpxw2j f1lwd9n0 fy0b8hm f1g2633v fx4kvgi fkvolse f1gxrt3a f1os76ua f1js9cnw f1g87ej0 freluf8 f1yggaq6 f2i3chp f1151osp florpoh f35kzfz ftp9m57 f1e288vi fz62hnz fixvuys f1nmofwh fc1c6mv f18a2er7 fhvkrdl fhxnn68 f1oce4bo fvhlfan f7tc0t0 f1ngf1n2 ffrzq6x f1yjiq2m f1aqdgql f1huvaf f10ij78l f1k94sa4 fkmfumq f1jvzkyl f1eu24ob f1xbfc1f fmf0lwf f107dsy8 f3w566c f4648sl f13zpkng f7unjfp f8p1rz fzu6h1w f1i1bi6h f1smo7hi f1sk1xod f1kgogdq f1gjktkp ft608jz f19dd9cz fg3xr24 fhd155k f1b8gl2e fg4b9ou flb4lo fdicbfk fgwcyh1 f1jbds0d f1fb9uea f1stuka4 fcrtu6g fwqh0xn f11w66yg f6e0e65 f1vvgu0 f1607507 f1m9bycv f1ntoah8 f1b694rt faql4r2 fpjuhzh fmavl6h"> <p>Full details and statistics are available in the attached press release <a data-val="d0aed1759a8842e0b302994bc36a7609" href="https://www.ote-cr.cz/en/about-ote/ote-news/press-release_20260226_guarantees-of-origin_2025.pdf" data-linktype="internal">here</a>.</p> </div> </div> </div> </div> </div> </div> </div> </div> </div> <div class="fai-CopilotMessage__footnote r1bn3aft ___7qar2c0 fcthzvy"> </div> <div class="fai-CopilotMessage__actions rmlvq19 ___7qar2c0 fcthzvy" data-tabster="{&quot;mover&quot;:{&quot;cyclic&quot;:false,&quot;direction&quot;:2,&quot;memorizeCurrent&quot;:true}}"> </div> </div> </div> <p> </p>

<p><strong>As of 14 January 2026, electricity traders will benefit from greater flexibility in responding to real-time changes in electricity generation and consumption. ČEPS, a.s., the transmission system operator and OTE, a.s., the nominated market operator are jointly extending the gate closure time for cross-border trading on the continuous intraday market to 30 minutes before delivery. This represents an extension of 30 minutes compared to the current arrangement. The possibility to trade up to 5 minutes before delivery on OTE local continuous intraday market after the cross-border trading is closed remains unchanged.</strong></p> <p><strong> </strong></p> <p>The new rules apply to cross-border transmission capacities on the borders with Germany and Austria and are implemented in accordance with European Regulation (EU) 2024/1747.</p> <p><strong> </strong></p> <p><strong>Greater efficiency and more opportunities for market participants</strong></p> <p><em>“We are pleased that the Czech Republic is among the first countries to implement the new framework,” </em>said Mr. Michal Puchel, Chairman of the Board of Directors of OTE. <em>“The extension of the cross-border intraday trading window will enhance market participants’ ability to respond to real-time changes in generation and consumption, which is key given the increasing integration of renewable energy sources with output dependent on variable conditions.”</em></p> <p> </p> <p>According to ČEPS, such measures are essential in today’s market environment. <em>“Energy markets have been extremely volatile in recent years. As the share of renewable energy sources increases, so do fluctuations in generation, which must be managed efficiently,</em>” said Mr. Pavel Šolc, Member of the Board of Directors of ČEPS responsible for energy market operations and dispatching. <em>“The 30-minute extension of the gate closure time for cross-border trades will enhance liquidity management across coupled markets and contribute to the secure and stable operation of the power system.”</em></p> <p> </p> <p><strong>Trading on Borders with Poland and Slovakia Remains Unchanged</strong></p> <p>The gate closure time for cross-border continuous intraday trading on the borders with Slovakia and Poland will remain 60 minutes before delivery. This is due to requests for derogation submitted by the transmission system operators of Slovakia and Poland to their respective national regulatory authorities. Once the specific implementation date for the extended cross-border trading on these borders is confirmed, market participants will be informed in advance.</p>

<p>The energy market in 2025 experienced another very dynamic year. Czech customers again actively responded to developments on the energy market and changed their energy suppliers on a large scale. According to OTE statistics, 596,136 consumption points changed electricity suppliers during the year. In the case of gas, this involved approximately 204,827 supply points.</p> <p>Read more in the press release <a data-val="760c325e90154fa0846777d1691b1d1e" href="https://www.ote-cr.cz/en/about-ote/ote-news/press-release_20260109_supplier-changes-in-2025.pdf" data-linktype="internal" target="_blank" title="pr supplier changes 2025">HERE</a>.</p>
