Inside the Rise of Storage with Tom Thunell of Tyba

Welcome back to The Pexapark Podcast! In the first part of the episode, we look at how policy and markets are converging around storage and flexibility. Germany is preparing an industrial power price subsidy from 2026, offering 50 €/MWh for part of energy-intensive companies’ load over three years, while France’s EDF has widened access to its long-term nuclear-based contracts to thousands more companies beyond just heavy industry. Romania is launching a demand-side flexibility market, allowing large users to offer demand reductions in the day-ahead market and share revenues with consumers – part of a broader shift across Europe and the US toward managing load as well as supply.In Italy, the post-MOXIE battery storage market is moving from tolling agreements toward day-ahead spread swaps as investors increasingly bet on widening spreads and more negative prices. Meanwhile in ERCOT, BESS revenues have dipped even as long-term arbitrage values reach record highs and toll offers stay flat, driving renewed interest in storage dealmaking.In the second part, Luca Pedretti speaks with Tom Thunell, co-founder of Tyba, about how the US battery storage market is evolving and what this shift means for IPPs transitioning from traditional renewables into storage-heavy portfolios.
