The AI boom has created an energy problem no one quite planned for. Every new data center needs power now - not in three years when the grid connection finally arrives. Developers are skipping the queue, installing on-site generation at a scale that would have seemed extraordinary five years ago.

But speed to power isn't the only pressure. Data center operators are also staring down net zero commitments, sustainability departments that want decarbonisation, and an energy trilemma of cost, carbon, and resilience.

In this episode Alejandro is joined by Alex Marshall, Group Business Development and Marketing Director at Clarke Energy. Alex explains why gas engines have become the bridging technology of choice for hyperscale data centers, what a 450 MW peaking station outside London actually looks like, and whether the engineering department and the sustainability team will ever agree.
