In our fourth podcast, Conall Bolger and Evie Doherty, discuss the emergent shape of the PPA market three months into SEM. They consider how SEM, by making players financially responsible for their traded position, profoundly alters the commercial underpinnings of PPAs in the market. These dynamics affect all players. The discussion reviews just how far participants have come in a short period of time and looks ahead to future changes such as corporate PPAs and new trading services.
