Rewiring the grid: How Alpiq is aligning culture and collaboration to power the energy transition

Published August 6, 2025 in Sustainability • 8 min read

Alpiq’s CEO rewires the Swiss power company’s legacy and culture to reshape it as a leader of the energy transition.

When Antje Kanngiesser returned to Alpiq as CEO in 2021, she stepped back into an industry in transition. An experienced energy executive, she had served a decade earlier as head of generation development at Alpiq, shaping the company’s strategic development of power generation and management across Switzerland and Europe.

Kanngiesser followed this with a series of senior leadership positions within the energy sector, witnessing its evolution and the need to decarbonize to meet the challenges of the energy transition. Back at Alpiq, she knew the terrain well, but the familiarity didn’t make the task any easier.

Headquartered in Lausanne, Alpiq supplies around 20% of Switzerland’s electricity production and runs power plants and sales businesses in many European countries, spanning hydropower, thermal, nuclear, and renewable assets. Alpiq sees its chance in becoming a leading flexibility provider that enables the continuing growth of renewable energy and its integration into the energy system.

The transition isn’t just technical. Hydropower, long a national staple, is vulnerable to climate change, and concessions end in the coming decades just as nuclear power is likely to phase out. Switzerland faces challenges integrating with the EU’s energy markets due to complex regulatory differences, national sovereignty over energy policy, and infrastructure gaps, which can create periods of relative isolation despite close economic ties. As expectations rise, infrastructure companies like Alpiq are caught between long-term decarbonization goals and short-term constraints, exacerbated by the commodity market, where scale and price usually matter most.

Kanngiesser’s vision is bold but pragmatic. She believes Alpiq’s edge lies not in scale, but in culture, and that the company’s ability to thrive in the transition depends on aligning internal mindsets and external relationships around a shared purpose.

But how can a midsize utility company rewire both its culture and its ecosystem fast enough to stay ahead of the curve?

The challenge: Moving a legacy business toward a net-zero future

When Kanngiesser took the helm at Alpiq, she inherited a legacy defined by massive hydropower infrastructure, nuclear generation, as well as a culture of technical excellence forged over decades. In a sector racing toward decarbonization, that legacy offered both credibility but also constraints.

Inside the company, the pressure was building for change. Alpiq’s engineers and operators prided themselves on the reliability of its legacy asset business. Sustainability, by contrast, still felt like a parallel narrative that was not yet fully integrated into the company’s identity or operations. The energy transition, while acknowledged, had yet to be translated into a unifying sense of urgency. “People were asking, ‘What does this mean for me?’” Kanngiesser recalls. “We needed to connect the dots between individual roles and the company’s climate ambition.”

The external landscape was even more fragmented. Alpiq had to respond to tightening emissions targets and EU energy market regulations. Long permitting cycles, political ambiguity, and volatile prices complicated investment in renewables and hydrogen. Meanwhile, climate change was increasingly threatening Alpiq’s most trusted asset: the glaciers that feed its hydropower plants.

“There’s no switch you flip to go sustainable,” says Kanngiesser. “Our portfolio was built in a different era. But the urgency is here now, and we have to navigate it with the assets, people, and politics we’ve got.”

For Alpiq, the challenge wasn’t just about strategy. It was about forcing clarity amid the complexity, aligning internal mindsets with external demands, and finding a way to lead, not despite legacy, but thanks to it.

“The goal was to make sustainability something tangible, not abstract; actionable, not aspirational.”

The solution: Activating culture and partnerships to power the transition

For Kanngiesser, leading Alpiq’s sustainability transformation isn’t about sweeping reinvention; it’s about reorientation. Rather than trying to erase the company’s legacy, she is reconfiguring it to meet the demands of a net-zero future.

The key to unlocking this transition? Embedding a clear sense of purpose into the culture and connecting it across every layer of the business.

Kanngiesser began by anchoring Alpiq’s strategy in a new corporate purpose, which is summed up in the tagline “Together for a better climate and improved security of supply.” With this purpose, Alpiq consciously embraces the tension between climate-friendly behavior and the requirements of security of supply, which is traditionally guaranteed by fossil energy but shall increasingly be assumed by renewable energy and carbon-neutral flexibility. This sums up the backbone of decision-making, shaping priorities from capital allocation to customer relationships. The goal was to make sustainability something tangible, not abstract; actionable, not aspirational.

Internally, she focused on building alignment through trust. In Europe, Alpiq is a smaller player in a sector where giants dominate on scale and price. But for Kanngiesser, that’s not the point. “We can’t compete on cost,” she says. “But we can compete on talent and culture.” She sees culture as a competitive asset, one that, if activated well, can become a force multiplier for transformation.

Following the implementation of a new Steering approach, shifting from divisions to Alpiq’s value chain, cross-functional working groups were launched to bridge gaps between business units. New formats encouraged teams to explore how their day-to-day decisions could contribute to decarbonization. Training and development sessions reframed topics like energy storage, hydrogen, and emissions reporting not as compliance issues but as innovation opportunities. Employees began to see themselves not just as operators of legacy infrastructure, but as stewards of the energy transition.

At the same time, Kanngiesser knew Alpiq couldn’t drive change alone. A small company in a complex, regulated industry needs partnerships to thrive. Under her leadership, Alpiq began actively engaging with competitors, policymakers, authorities, and system operators to push for collaboration on the systemic question of renewable integration via flexibility. This also means developing solutions such as green hydrogen and batteries to enhance supply security, especially during winter, alongside promoting alpine PV, hydropower, and cross-border energy trading, while also addressing climate challenges like water scarcity and flooding.
These alliances aren’t about branding; they are about building coalitions that can shift the system. Whether promoting hydrogen development in Switzerland, France, Spain, and Finland or advocating for a more nuanced view of Swiss energy assets in Brussels, Alpiq started showing up differently: not just as an energy provider, but as a strategic partner in shaping the low-carbon future.

This dual track – internal alignment and external collaboration – has allowed Alpiq to move forward without overpromising. The company isn’t pretending the road to net zero will be smooth. But it’s making space for difficult trade-offs, balancing realism with ambition.
“Especially with infrastructure, you can’t have overnight transitions,” Kanngiesser reflects, “But you can have direction. You can commit. And you can bring people with you.”

Five key takeaways

Alpiq’s story shows how a mid-sized company can lead big change, not by scaling faster than others, but by aligning culture and partnerships around a shared purpose. Here are five lessons to take forward:

Anchor transformation in culture, not just targets

Lasting change doesn’t start with metrics, it starts with people. Empower teams with purpose and align behaviors with long-term ambition.

Operationalize purpose through roles and routines

A strong vision only matters if it’s felt across the organization. Connect sustainability to individual responsibility and make it part of daily work.

Balance urgency with realism

In complex industries, credible progress means acknowledging trade-offs. Avoid greenwashing by being transparent about constraints and compromises.

Leverage partnerships when scale is out of reach

You don’t need to be the biggest player to lead. Collaborating across the ecosystem can unlock innovation, amplify influence, and accelerate systemic change.

Shape the system from within

Engage regulators and peers early. Influence policy not by pushing back, but by offering practical insight grounded in experience.

The next chapter is about integration.

What’s next

Alpiq’s transformation is gaining momentum, but for Kanngiesser, the real test lies ahead: sustaining energy through complexity and turning a deeply rooted culture into a lasting source of competitive advantage.

The next chapter is about integration. Sustainability is no longer a separate track; it must become the default language across operations, strategy, and leadership. To accelerate this shift, Alpiq is embedding climate targets into performance systems, scaling cross-functional programs, and investing in a new generation of talent ready to lead through ambiguity.

Externally, Alpiq is leaning further into its role as a bridge-builder. Through collaborations addressing the systemic question of renewable integration, augmenting no-to-low-carbon security of supply, and addressing climate change, the company is pushing for innovation that works not only in theory but in the messy, real-world context of aging infrastructure, price volatility, and political complexity. These collaborations aren’t a side project; they’re a core strategy for shaping a future energy market that rewards agility and alignment over sheer size.

Kanngiesser is also focused on voice. By stepping up engagement with policymakers, NGOs, universities, and peers, Alpiq is working to reframe the energy debate, championing pragmatic pathways to net zero that reflect the realities companies face on the ground. It’s not about slogans. It’s about system change.

For Alpiq, the road ahead remains complex, marked by trade-offs, ambiguity, and accelerating change. But with a culture aligned around purpose, and partnerships designed for scale, the company is building exactly what the current moment calls for: a system ready to adapt, evolve, and lead.
