Inside Alpiq’s Flexibility Strategy with Nadiya Vargola and Lukas Gresnigt (Alpiq)

As Europe accelerates toward a low-carbon electricity system, storage is under the spotlight. But while battery deployments are scaling quickly, long-duration assets like pumped hydro remain a crucial part of the flexibility mix.

So how do these technologies complement each other, and what’s really needed to make large-scale storage viable across different European markets?

In this episode of Transmission, Ed talks with Lukas Gresnigt (Member of Executive Board) and Nadiya Vargola (Head of BESS Business Development) at Alpiq.

Over the conversation they explore Alpiq’s approach to balancing legacy infrastructure with modern flexibility. From developing batteries across multiple markets to operating an 80-to-100 year lifespan pumped hydro plant in the Swiss Alps, this conversation dives into the commercial realities of grid-scale storage. You’ll hear how Alpiq is navigating cross-border market design, adapting gas peaker strategies in solar-saturated regions like Iberia, and structuring long-term investments in flexibility across Europe.

Key insights include:

• How pumped hydro and batteries complement each other, and where each technology shines
• What it takes to bring large storage projects to life, from decade-long build times to multigenerational returns
• How Alpiq is acquiring and developing BESS assets across European markets
• Why Iberia is a case study in flexibility, and how legacy gas assets are adapting to new solar peaks
• What market reforms are needed to unlock storage at the scale the energy transition demands
