As more distributed energy resources arrive unbidden onto the power grid, they are increasingly requiring us not to just think about new utility business models, but to radically rethink what a utility might look like. What if millions of distributed resources become the dominant resources, and the grid assumes a subordinate role as a residual supplier of energy? What if the control of the system is also decentralized, through the actions of millions of devices? What if the roles of transmission system operators and the distribution system are diminished as their responsibilities are distributed across all those devices? And how will utilities, power market operators, regulators, legislators, and local officials deal with a radical shift in their roles and responsibilities? These are the questions that our guest in this episode—an 18-year veteran of wholesale power market design at the California ISO—thinks about, and he shares those deep thoughts with us in this wonky yet heady discussion.

Guest:Lorenzo Kristov is an independent consultant focusing on power system transition to integrate high levels of renewable generation and distributed energy resources (DER). From 1999 to 2017 Lorenzo worked at California ISO as a principal in market design and infrastructure policy, where he was a lead designer of the locational marginal pricing (LMP) market system the ISO implemented in 2009. Areas of expertise include: wholesale market design; DER participation in wholesale markets; coordination of transmission-distribution system operations; distribution system operator (DSO) models and distribution-level markets; microgrids and energy resilience strategies; whole-system grid architecture.
