info_outlineBlake King, power markets engineer at Galaxy, formerly of Oak Ridge national lab and ERCOT, joins us to talk about how changing grids are accommodating an influx of load from Bitcoin miners. In this episode:
- Why the grid is undergoing a radical transformation today
- Blake’s background in electrical engineering, power system modeling, and renewable development
- The origin of Blake’s papers on bitcoin mining and the grid
- Bitcoiner misconceptions about mining?
- Why Bitcoin is not a battery
- Why you can’t just arbitrarily add load to the grid

- Why renewable generation requires more transmission
- How renewable generation costs are increasingly upfront as compared to thermal generation
- Are bitcoiners overrating the importance of controllable load?
- Why Bitcoin miners may be over ambitious in terms of modeling ancillary service payments
- Are ancillary markets going to increase in size with more renewable generation?
- Economic demand response versus formal ancillary services
- Different types of ancillary services products
- Why load resources are able to bid out thermal generation in ancillary services markets
- How exactly Bitcoin miners get signals to curtail their load during scarcity events
- Does being a load resource imply ‘voluntary’ curtailment?
- Why miners owe it to the grid operator to be transparent in their breakeven price and operating plans
- How weather in Texas could affect block arrival times in Bitcoin
- Why the commodification of ASICs would increase the integration of the renewable energy sector and bitcoin mining
