How a battery gets optimised, from the moment a contract is signed to the millisecond a trade is placed, is still a black box for most people in the industry. Understanding that process is the difference between leaving money on the table and extracting maximum value from every asset.

In this episode of Transmission, Ed Porter is joined by Fabrizio Fenu, Head of Business Development at EDF UK. They pull back the curtain on how battery optimisation actually works at scale: how assets are treated fairly across a large portfolio, why merchant, floor and tolling contracts suit different investors, what role AI and algorithms play on a live trading desk, and why co-located solar and battery projects are harder to finance than they look.
