Stock Market Week 17/26: RENIXX Hits New Yearly High - Storage Puts Pressure on Gas - Solaredge: New Industrial Storage - Scatec: 60 MW Solar for Tunisia - Nordex Turbine: New Options
Münster (Germany) - The RENIXX reclaimed the 1,300-point mark last week and reached a new yearly high. The week continued to reflect a volatile environment with mixed developments. While conditions in energy markets have stabilized somewhat recently, structural drivers in the power system are increasingly shifting toward flexibility and security of supply.
Green stocks remain in a geopolitical tension field – storage boom and structural shift in the energy mix In energy markets, battery storage and flexible capacities are increasingly gaining attention. According to the IEA, the global battery storage market grew by around 40% in 2025, driven by declining costs, reaching a new record level of approximately 108 GW of capacity (2024: around 77 GW). At the same time, recent BloombergNEF data indicate that construction costs for new gas-fired power plants have increased by about 66%. This significantly weakens the competitiveness of gas compared to flexible alternatives such as battery storage.
Additional data from Ember highlight the structural shift in the global power system: in 2025, wind and solar energy fully covered global electricity demand growth for the first time and also surpassed coal-fired generation. This confirms the trend of an accelerating transition in the global energy mix toward renewable energy.

Scatec commissions 60 MW Tozeur solar park in Tunisia
Scatec ASA and Aeolus SAS have commissioned the 60 MW Tozeur solar park in Tunisia, retroactively effective from March 4, 2026. The project is secured by a 30-year power purchase agreement (PPA) with the state-owned utility STEG. In addition, the 60 MW Sidi Bouzid solar park was already commissioned at the turn of the year. Both projects were awarded through a government tender process.
Scatec shares gained 3.4% to EUR 11.04.
N175/6.X turbine receives 7.3 MW operating mode and new tower options for higher yield
Nordex is enhancing its successful Delta4000 turbine platform with several innovations for the N175/6.X model. A new operating mode and additional hybrid tower options are intended to increase energy yields, reduce costs, and improve turbine flexibility, particularly for use in core European markets. These enhancements continue the company’s strategy of optimizing onshore wind projects. Key features include a power upgrade of the N175/6.X to 7.3 MW for higher annual energy production and new tower configurations for Germany and Europe.
Nordex shares were unable to maintain their positive trend, declining by 0.7% week-on-week to EUR 44.76.
Technical outlook: RENIXX breaks out of sideways range
From late 2023 to early January 2025, the RENIXX moved within a pronounced sideways range between 1,000 and 1,200 points. The significant low of 748 points in 2025 marked an important turning point and has since acted as a key support level.
From this low, the index has recovered significantly and reached a new yearly high of 1,331.85 points last week. This marks a clear breakout above the previous trading range of 1,200 to 1,300 points.
In the short term, the breakout is technically confirmed. For a sustained upward trend, however, the index must stabilize above the former resistance zone, now located between 1,280 and 1,300 points, which becomes the first support area in case of pullbacks. Below this, the 1,200-point level remains an important reference mark, while the key long-term support zone lies between 1,000 and 1,100 points.
RENIXX starts the week strongly
In early trading of the new week, the RENIXX is moving higher. Strong gains are seen following the release of Nordex’s first-quarter 2026 results. Goldwind, BYD, EDPR Renewables, and Vestas are also posting gains, while China Longyuan, Array Technologies, Xinyi Solar, Ormat, and Daqo New Energy are declining.
