learning lessons about deeply decarbonized electricity markets from around the world including optimal prices in non-convex markets, reliability insurance, and system security

Farhad Billimoria, Conleigh Byers, PhD, Ahlmahz Negash, PhD, and Paul Dockery discuss adaptation of market design for the energy transition including fat tails and increased exposure to extremes; batteries and price responsive demand; natural gas fragility and marginal pricing; and inverter-driven resources and system security. Then the team plays a new game where they synthesize expert explanations of convex vs non-convex pricing and reliability insurance.
