Flexibility, Security and Solar’s Next Growth Phase, with Walburga Hemetsberger

Building the sustainable cloud Europe needs, with Sabrina Breidert

In this episode of Watt Matters, Ana speaks with Sabrina Breidert, Head of Sales at Yorizon, about the intersection of digital infrastructure, energy transition, and European sovereignty. As AI-driven workloads accelerate and data center demand rises across Europe, the conversation explores how cloud infrastructure is becoming a strategic pillar of both sustainability and resilience. Sabrina shares how Yorizon is rethinking the hyperscaler model with a distributed edge approach: modular, wood-based data centers powered by 100% renewable energy, designed for carbon transparency, regulatory alignment, and local integration. From liquid cooling and district heating reuse to open-source architecture and vendor independence, the discussion highlights how sustainability, sovereignty, and performance can reinforce one another rather than compete. Takeaways * Why cloud infrastructure is no longer “neutral” in the energy transition * The risks of centralized hyperscaler dependency * How distributed edge data centers improve resilience and compliance * Achieving PUE below 1.1 through integrated design * Reusing waste heat to support local district heating networks * Transparent carbon reporting per workload for ESG compliance * Open-source architecture as a sovereignty strategy * Preparing for AI workloads with high-density, liquid-cooled GPU racks * Building regional economic ecosystems around data infrastructure Chapters 00:00 – Introduction to Yorizon and the European cloud vision 03:30 – Hyperscalers vs. distributed edge infrastructure 06:15 – Sustainability beyond marketing: energy, PUE, and efficiency 09:00 – Liquid cooling and district heating integration 11:45 – ESG reporting and carbon transparency 14:00 – Digital sovereignty and open-source cloud stacks 18:00 – Community impact and regional partnerships 20:00 – AI readiness and sustainable scaling 23:00 – Expansion plans across Europe through 2030 25:00 – The future of co-located renewables and data centers To learn more about accelerating solar project success and how PVcase supports developers from design to delivery, visit www.pvcase.com [http://www.pvcase.com].

Flexibility, Security and Solar’s Next Growth Phase, with Walburga Hemetsberger

In this episode of Watt Matters, Ana speaks with Walburga Hemetsberger, CEO of Solar Power Europe, about the shifting priorities shaping Europe’s energy transition. As solar becomes a central pillar of energy security and competitiveness, the conversation explores how policy, flexibility, and system design must evolve to support the next phase of growth. Walburga outlines Solar Power Europe’s four strategic priorities: electrification, flexibility, resilient supply chains, and strong communications. From the urgent need to deploy 10x more battery storage by 2030 to the role of solar in powering AI-driven data centers, this episode examines what it will take to move from rapid capacity additions to a truly future-proof energy system. Takeaways: * Solar is no longer just a climate solution — it is a strategic security asset for Europe. * Electrification must accelerate beyond today’s stalled 23% share of final energy. * Flexibility — through demand response and battery storage — is now essential. * Europe needs 10x more battery capacity by 2030 to stabilize solar growth. * Revenue stacking and regulatory reform are critical for battery investment. * Implementation gaps, especially in permitting and grid reform, remain a major bottleneck. * Energy security strategies must evolve beyond fossil-based thinking. * Solar’s growth is strong, but business models are under pressure from negative pricing and curtailment. * Data centers and AI could become key drivers of new electricity demand — if powered sustainably.

Latin America’s solar boom, with Guilherme Chrispim

Latin America’s renewable energy story is no longer just about installing more megawatts. In this episode of Watt Matters, Ana speaks with Guilherme Chrispim, Brazilian solar leader and former head of the Brazilian Distributed Generation Association, about how the region is navigating rapid growth, grid constraints, and the next phase of the energy transition. From Brazil’s distributed generation boom to Chile’s early leadership in battery storage, Guilherme shares an insider’s view of how different markets are evolving — and why integration, flexibility, and digital intelligence now matter more than raw capacity additions. As curtailment rises and data center demand accelerates, the conversation shifts toward storage, system efficiency, and the role of smarter networks in ensuring sustainable growth. This episode explores how Latin America can transform today’s bottlenecks into tomorrow’s competitive advantage — and why the next chapter of renewables will be defined by optimization, not expansion alone.

Solar’s next survival test, with Peter Pongracz

Solar is still scaling globally — but the rules of the game have changed. In this episode of Watt Matters, Ana speaks with Peter Pongracz, Founder of Soliverse, about the diverging realities shaping today’s solar markets. While global installations continue to rise, developers across Europe and the U.S. are navigating curtailment, grid congestion, price pressure, and heightened financing scrutiny. Meanwhile, new markets in the Middle East and Southeast Asia are accelerating with strong policy backing. Peter shares insights from his conversations with developers, investors, and policymakers across markets. From the rise of hybrid projects and the central role of battery storage to reshoring manufacturing and the need for a unified solar software workflow, this episode explores what it now takes to build resilient, bankable projects. As standalone solar gives way to flexibility-driven systems, success increasingly depends on disciplined site selection, grid strategy, and integrated digital tools. Takeaways * Policy clarity is the primary driver of market acceleration * Hybrid solar-plus-storage projects are becoming the new standard * Grid congestion and curtailment are reshaping project economics * Battery energy storage is critical to unlocking flexibility * Capital is flowing toward lower-risk, grid-secured projects * Early-stage site selection determines long-term bankability * Manufacturing reshoring is driven by energy and supply chain security * Fragmented software workflows create costly data loss and inefficiencies * Bankability remains the barrier to wider adoption of new yield tools * Resilience will define the next phase of solar growth Chapters 00:00 – Peter’s journey from SaaS sales to founding Soliverse 04:00 – Global divergence: Middle East growth vs. Western slowdowns 08:00 – Curtailment, grid congestion, and the rise of storage 13:00 – Is standalone solar dead? The shift to hybrid projects 18:00 – Policy, reshoring, and energy security in Europe and the U.S. 24:00 – Software fragmentation and the need for a solar “gold standard” 31:00 – Why 80% of projects never get built 35:00 – Solar resilience and optimism for the future To learn more about building the future of large-scale solar and how PVcase can help, head to www.pvcase.com [http://www.pvcase.com]

Solar Resilience and Where Power Is Going, with Gerard Reid

In this episode of Watt Matters, Ana speaks with Gerard Reid, global energy transition strategist, investment expert, and co‑host of the Redefining Energy podcast, about the evolution of solar from niche technology to foundational element of the future energy system. Gerard shares how his early skepticism about solar shifted as costs fell, why solar paired with storage is reshaping the economics of power, and how systemic thinking — not isolated technology debates — is essential for navigating the next decade of the energy transition. They explore grid resilience, decentralization, and the economic realities that will determine winners and losers in tomorrow’s energy markets.
