In this third part of a trilogy of shows about how to decarbonize grid power, former utility regulator Travis Kavulla offers his thoughts on how wholesale electricity markets can use competition to deliver clean electricity. Following our discussion about reforming wholesale markets in Episode #90, and our exploration of how state policies can directly choose clean power in Episode #97, Travis offers some deep thoughts on the respective roles of FERC and state regulators, proposed reforms to PURPA, FERC’s showdown with PJM, the politicization of FERC, the recent battle in Ohio over HB6 (bailing out its nukes and coal plants), and other regulatory battles du jour. So much power market wonkery in such a small package!
Australia has the highest proportion of households with rooftop solar PV systems of any country in the world. It also has the second-dirtiest grid in the world, getting three-quarters of its power from coal. As such, Australia might as well be the global poster child of energy transition, with both a huge load of dirty power plants it needs to retire, and a huge set of distributed and variable solar and wind systems that it needs to integrate into its power grid, while keeping everything balanced, without being able to import or export electricity from other nations. It’s a fascinating case study in wholesale markets, renewable incentives, technical balancing issues, and yes, acrimonious political debate between Browns and Greens. To help us understand this complex picture, we speak with Dr. Jenny Riesz, a Principal at the Australian Energy Market Operator (AEMO), the operator of Australia’s largest gas and electricity markets and power systems. Dr. Riesz works on adapting AEMO’s processes and functions to ensure ongoing security and reliability as the power system transitions to renewables, and leads its work program on matters such as frequency control, analysis on declining inertia, and possible solutions such as Fast Frequency Response.
