MUNICH, Sept. 30, 2026 /PRNewswire/ -- Europe's power market is sending two contradictory signals this summer. Renewable electricity is becoming so abundant that prices are falling below zero. Yet extreme heat is pushing power prices to levels more commonly associated with winter. Behind both trends lies the same challenge: Europe's power system is entering an era where dynamic balancing, precision dispatch and system resilience are becoming as important as generation itself.

Two extremes, one market

This past summer put the continent's changing electricity system under new pressure.

As temperatures climbed, demand for cooling surged just as parts of the generation fleet strained under the heat. High river temperatures and low water levels forced some nuclear plants to reduce output. Low wind conditions and reduced thermal plant efficiency tightened supply further.

The result was an unusually tight summer power market, with electricity prices rising to levels more commonly seen in winter. In Germany, day-ahead prices reached around €210/MWh during periods of extreme heat—levels typically seen in winter, according to LSEG data cited by Reuters.

Yet only hours later, the same markets faced the opposite problem: too much electricity.

Negative prices have become increasingly common as solar and wind penetration rises faster than the power system's ability to absorb, shift, and transmit renewable generation. According to the International Energy Agency, negative-price hours accounted for around 6% of the year in several major European markets in 2025, including Germany, France, Spain, and the Netherlands. Germany alone recorded 573 hours of negative wholesale prices.

Curtailment tells the same story. In May 2026, an estimated 1.28 TWh of solar generation was curtailed in Germany, and more than 2.4 TWh in Spain, as grids struggled to accommodate output during periods of abundant sunshine.

The apparent contradiction points to a deeper shift: Europe does not simply have a generation problem. It has a timing, location and flexibility problem.

From Generation to Dynamic Balancing

The challenge is no longer simply whether enough electricity can be generated. It is whether electricity is available when and where it is needed.

At midday, abundant solar generation can push wholesale prices toward zero or below. Hours later, solar output falls while evening demand remains high, creating a very different price signal. Extreme weather widens the gap further by simultaneously increasing demand and constraining conventional generation.

For renewable asset owners, value is therefore increasingly determined not only by how much electricity an asset generates, but by how effectively that electricity can be managed, shifted and dispatched.

Storage: From Energy Shifting to System Support

Battery storage is emerging as a key tool for balancing increasingly variable power supply and demand across Europe.

By absorbing electricity during periods of oversupply and dispatching it when demand and prices rise, batteries can reduce curtailment while improving the value of renewable generation. Increasingly, they are also expected to provide frequency response, capacity, and grid-support functions.

But not all storage is built for this new reality. The next generation of utility-scale systems must handle multiple durations, deliver high round-trip efficiency and provide the grid-forming capabilities required by evolving European grid codes. Just as importantly, these systems must be deployable at scale and commissioned efficiently.

This principle has shaped the development of Sungrow's PowerTitan series, which brings together battery technology, power conversion, thermal management and grid-support capabilities within an integrated platform.

From Flexibility to System Resilience

The value of fast-responding storage is already visible in Europe. In December 2023, a trip on the IFA1 interconnector between the UK and France resulted in the loss of around 1 GW of imported power, sending system frequency down to 49.3 Hz. Multiple hundred-megawatt-scale grid-connected battery systems operated by Sungrow in the UK responded within one second, providing frequency support and helping the system return to the normal frequency range within five minutes.

The episode illustrates a broader shift: storage is no longer only an energy-shifting asset. It can also become part of the power system's resilience layer, responding in the seconds that matter most.

From Technology to Scalable Delivery

As storage projects grow in scale, however, technology must be matched by execution.

At the 100 MW/331 MWh Bramley project in the UK, the PowerTitan 2.0 BESS supported the project's progression from grid energisation to commercial operation in just two weeks. At a much larger scale, Sungrow's 7.8 GWh energy storage project in Saudi Arabia moved from production to deployment in two months and was connected to the grid in 2025. The project demonstrates that grid-forming storage can be manufactured, delivered and commissioned not only as an individual asset, but at multi-gigawatt-hour scale.

Together, these projects build the technology, operational experience and delivery foundation behind the latest generation of the platform: PowerTitan 3.0.

PowerTitan 3.0: Engineering for the Next-Generation Grid

Built for applications ranging from 2 to 8 hours, PowerTitan 3.0 packs 7.14 MWh of battery capacity into a single 20-foot container, paired with a 1.78 MW power conversion system. Its SiC-based PCS enables system-level round-trip efficiency of up to 92%, minimizing energy loss during daily cycling. And with integrated grid-forming capabilities, it is engineered to meet evolving European grid codes that now prioritize stability alongside energy shifting.

"The next phase of Europe's energy transition is not simply about generating more renewable electricity. It is about making that electricity available at the right time, in the right place and in the right form. This is where flexible energy storage can create new value for both renewable assets and the wider power system," said Javier Izcue Elizalde, Vice President Europe at Sungrow. "This year, Sungrow estimates delivering 10 GWh of PowerTitan 3.0 across Europe."

A Market Moving Toward Flexibility

The shift is already visible in deployment figures. According to SolarPower Europe's European Battery Market Outlook 2026–2030, Europe installed around 36 GWh of new battery storage in 2025, taking operational capacity above 100 GWh. SolarPower Europe expects annual installations to exceed 50 GWh in 2026 and reach 138 GWh by 2030, with utility-scale storage becoming the key growth engine.

Europe does not simply need more renewable electricity. It needs a power system capable of moving that electricity across time, responding to increasingly extreme conditions, and extracting more value from every megawatt-hour generated.

In a market where prices can swing from below zero to €210/MWh within hours, flexibility is no longer a backup option. It is becoming a core source of value—and a new source of value for the energy transition.

Der hessische Ministerpräsident Boris Rhein (CDU) hat eine Neujustierung des Umgangs mit der AfD im Bundestag gefordert und damit eine innerparteiliche wie parlamentarische Grundsatzdebatte angestoßen. In einem Interview mit dem Magazin „Stern“ plädierte der CDU-Politiker dafür, der AfD die ihr nach dem üblichen Verteilungsschlüssel zustehenden Vorsitzendenposten in den Fachausschüssen des Bundestags nicht länger zu verwehren. „Die Partei ist gewählt, und so sollte man mit ihr auch umgehen“, sagte Rhein und verwies darauf, dass die AfD im hessischen Landtag und in anderen Länderparlamenten bereits Ausschussvorsitze innehat.

Im Bundestag verfügt die AfD wie die anderen Fraktionen über ein Vorschlagsrecht für bestimmte Ausschussvorsitze. Bisher scheiterte sie jedoch regelmäßig daran, dass ihre Kandidatinnen und Kandidaten bei den Wahlen in den Ausschüssen nicht die Unterstützung der Abgeordneten der übrigen Parteien erhielten und damit die nötigen Mehrheiten verfehlten. Eine Klage der AfD-Bundestagsfraktion vor dem Bundesverfassungsgericht blieb im September 2024 ohne Erfolg; Karlsruhe sah keinen Anlass, in das Verfahren der Ausschussbesetzungen einzugreifen. Politisch aber gewinnt die Frage durch Rheins Vorstoß neue Brisanz.

Rhein grenzt sich zugleich von einer inhaltlichen Annäherung an die AfD ab und lehnt ein Verbotsverfahren gegen die Partei ab. Er halte das vielzitierte Bild einer „Brandmauer“ für falsch, betonte der CDU-Landeschef. Für die Union gelte: „Wir grenzen uns klar von der AfD ab, aber wir grenzen die Partei nicht aus.“ Das müsse sich auch in der Parlamentsarbeit widerspiegeln. Anstelle juristischer Schritte warb Rhein dafür, die AfD politisch zu stellen: Die CDU müsse den Wählerinnen und Wählern „ein besseres Angebot machen“ und die „Deutungshoheit über die Alltagsfragen“ zurückgewinnen. Eine Zusammenarbeit mit der AfD setze aus seiner Sicht eine „Politik der klaren roten Linien“ voraus.

Die AfD bewertet die Äußerungen des hessischen Regierungschefs als Signal eines sich abzeichnenden Kurswechsels in der Union. Der Parlamentarische Geschäftsführer der AfD-Bundestagsfraktion, Bernd Baumann, sprach gegenüber der Nachrichtenagentur AFP von einem „überfälligen“ Schritt und einem Zeichen für ein „generelles Umdenken in der CDU“. Die Forderung nach Ausschussvorsitzen sei „nur der erste Schritt – weitere werden folgen“, prognostizierte Baumann. Angesichts jüngster Wahlergebnisse sehe er die Union unter Druck, ihre bisherige Ausgrenzungsstrategie zu überdenken. Koalitionsfraktionen im Bundestag wiesen einen von Rhein geforderten Kurswechsel allerdings zurück und halten bislang an der Linie fest, AfD-Kandidaten für Ausschussvorsitze nicht zu unterstützen.

In den Fachausschüssen des Bundestags wird ein Großteil der inhaltlichen Gesetzgebungsarbeit vorbereitet. Die Vorsitzenden spielen eine zentrale Rolle bei der Organisation der Beratungen und der Tagesordnungsgestaltung. Die Verteilung dieser Schlüsselpositionen erfolgt nach einem festgelegten Schlüssel zwischen den Fraktionen, doch bleibt die tatsächliche Besetzung an die Wahl durch die Ausschussmitglieder gebunden. Vor diesem Hintergrund berührt die von Rhein angestoßene Debatte nicht nur die Machtbalance zwischen den Fraktionen, sondern auch die Frage, wie das Parlament mit Parteien umgeht, die zwar demokratisch gewählt sind, von großen Teilen des Hauses aber weiterhin klar abgelehnt werden.
