Three years ago, the best price for a ready-to-build solar project in Spain was €200,000 per megawatt — today it is €50,000. Batteries have moved the opposite way, with ready-to-build prices climbing to around €100,000 per megawatt and a 30GW pipeline now stacking up behind them.

Ed Porter sits down with Carmen Izquierdo Serrano, founder of nTeaser, the renewable energy marketplace where many of Spain's BESS, solar, and co-located deals are transacting, to unpack what those numbers actually mean for investors entering the Spanish power market and how the post-blackout urgency, and bottlenecks in financing and labour will shape who wins the next phase of Spain's energy transition

They cover:

Why Spanish solar ready-to-build prices have collapsed from €200,000 to €50,000 per megawatt while battery prices have climbed to ~€100,000 per megawatt in the space of three years
How the 30GW Spain BESS pipeline stacks up against the ~3.5GW expected to be operating by 2030, and why Carmen thinks that operating-asset forecast is conservative
Where the real bottleneck is for delivery - not developers or permits, but bank financing and the skilled labour needed to construct the projects
Why Italy's BESS market has slowed after the first MACSE auction while Spain has accelerated, and what that means for capital allocation across Southern Europe.
How buyer expectations on arbitrage revenues are likely to be cannibalised as more batteries enter the market, and which revenue streams banks will actually finance against
