Podcast: Power marketing and energy markets with John Larkey

Financing large-scale renewable energy projects is no small feat. Developers face complex challenges, from securing capital and managing market risk in volatile electricity markets and navigating shifting regulations. Corporate power buyers play a huge role in shaping the market, and with the surge in large load users and developments in colocation, the industry is facing a huge change.


In this episode of Transmission, Quentin sits down with John Larkey, Senior Vice President of Power Marketing at National Grid Renewables. They explore how large-scale renewable energy projects secure financing, navigate power markets, and manage risk. Over the conversation, you’ll hear about:

  • The evolution from physical to financial trading in power markets
  • Impact of corporate buyers on the power purchase market.
  • Virtual Power Purchase Agreements and their role in the market.
  • Co-location of generation with large loads and the challenges and opportunities in the US power grid.
  • Current state and future potential of flexibility in power markets.
