Stock Market Week 04/26: RENIXX Firmly Above 1,200 Points - Enphase and Goldwind Post Double-Digit Gains - Ormat Takes Stake in Sage Geosystems - Ørsted Nears Completion of Mega Project in Taiwan
Münster (Germany) - After the strong rise in the first trading weeks of the year, the RENIXX remained stable above the 1,200-point mark last week. Compared to the previous week, the index closed almost unchanged.
Technical outlook: RENIXX establishes itself above 1,200 points
From the end of 2023 to early January 2025, the RENIXX traded sideways in a range between 1,000 and 1,200 points. The drop to 748 points in 2025 marked a significant interim low and an important turning point, which now serves as a key support zone. Since that low, the RENIXX has already climbed to 1,244 points, gaining around 66.5 percent. With rising volatility, the index temporarily advanced to nearly 1,300 points, once again reaching the upper boundary of the former trading range. Profit-taking subsequently pushed it back toward the 1,000-point level. After a subsequent rebound, the index is now showing a neutral sideways phase with a positive bias. Last week, the RENIXX closed above the 1,200-point mark. If the index can hold this level, the next hurdle at 1,300 points comes into focus, making a further dynamic upswing appear possible. On a year-to-date basis in 2026, the RENIXX remains up 10.5 percent after Friday’s close.
Company news week 04/26
Ormat invests USD 25 million in Sage Geosystems - pressure geothermal technology set to enter pilot phase
Ormat has announced an equity investment of USD 25 million in Sage Geosystems. Sage plans to test its pressure geothermal technology at an existing Ormat power plant. The company aims to extract heat from hot, dry rock while simultaneously testing a pressure-based energy storage system. If the pilot project is successful, Ormat will have the option to develop projects based on this pressure geothermal technology. In addition, Ormat has been awarded the Telaga Ranu geothermal area. In the planning documents of the state-owned utility PT PLN (RUPTL), the area is identified as having potential of up to 40 MW of baseload-capable geothermal capacity. Development through the end of 2030 is intended to replace diesel-based power generation and strengthen energy security in the region. By the end of the week, Ormat shares were up 2.3 percent at EUR 104.10.
Ørsted in Taiwan on the home stretch - all turbines installed at the Greater Changhua 2b and 4 offshore wind farm complex
Ørsted has completed the installation of all 66 wind turbines at the Greater Changhua 2b/4 offshore wind farm in Taiwan. This marks the end of the construction phase of the 920 MW project, one of the largest offshore wind developments in the Asia-Pacific region and a key component of the energy transition there. The 14 MW SG-14-236 turbines from Siemens Gamesa were installed within a single construction season—despite challenging weather conditions in the Taiwan Strait. The project makes large-scale use of pile-free suction bucket jacket foundations for the first time and sets new benchmarks with 115-meter-long rotor blades. Ørsted shares rose 1.3 percent to EUR 18.21.
U.S. Patent and Trademark Office rejects challenges against First Solar’s TOPCon patents
First Solar has scored a win in a patent dispute. The U.S. Patent and Trademark Office (USPTO) has rejected three Inter Partes Review (IPR) petitions filed against First Solar’s patents. The petitions were submitted by Jinkosolar, Mundra Solar, and Canadian Solar, seeking to challenge the validity of TOPCon patents held by the U.S. manufacturer. Jinkosolar and Canadian Solar sought to invalidate U.S. Patent No. 9,130,074, while Mundra Solar challenged U.S. Patent No. 9,666,732. Both patents relate to manufacturing processes for TOPCon crystalline silicon photovoltaic cells. At the same time, First Solar has filed lawsuits in the U.S. alleging patent infringement. These cases are pending before the District Court for the District of Delaware. First Solar shares fell 2.4 percent last week to EUR 204.95.
