On November 29, 2022, the Electric Reliability Council of Texas (ERCOT) published a seasonal assessment and resource adequacy report for its region, concluding that Bitcoin mining operations are flexible assets that benefit the Texas grid during winter and extreme peak load periods. The 22-page study, based on historical data and extreme peak load scenarios, provides quantitative evidence challenging anti-mining narratives.
Key Findings: Miners Can Curtail 1.7 GW Instantly
The report states that Bitcoin mining facilities can curtail their operations to relieve roughly 1.7 gigawatts (GW) of energy demand during the Texas winter. Unlike other large industrial loads that cannot adjust to direct response (DR) signals, Bitcoin miners are uniquely able to shut down almost immediately due to their economic incentive: when the spot price of Bitcoin approaches production costs, miners voluntarily halt. ERCOT estimated the breakeven cost at $86 per megawatt-hour (MWh), based on an Antminer S19 as of early November 2022.
ERCOT also notes that because miners operate continuously (searching for blocks), they provide a reliable revenue stream for grid operators while retaining the flexibility to disconnect during peak demand. The report emphasizes that even with miners consuming power, the grid is expected to have sufficient capacity for the winter season (December 2022 – February 2023) under typical conditions.
Industry Collaboration: Demand Response in Practice
ERCOT is not alone in studying Bitcoin-based DR. Duke Energy, the second largest U.S. energy corporation, began analyzing Bitcoin mining's role in July 2022; its lead analyst confirmed that miners provided data for a DR study. In the same month, Bitcoin mining infrastructure provider Lancium partnered with Texas battery-storage firm Broad Reach Power. Under extreme grid conditions, batteries can keep Lancium's mining facility running without reducing computational power, illustrating how mining can integrate with storage for sustained flexibility.
These examples underscore that Bitcoin mining is evolving from a simple energy consumer into a smart grid resource that absorbs excess power and sheds load during emergencies.
Political Pressure vs. Empirical Reality
The report's release comes amid pressure from U.S. lawmakers who requested ERCOT for information on mining operations, arguing that miners contribute to climate change and potentially destabilize the grid. Despite this, ERCOT's new CEO publicly stated: “We want to be able to serve any business that wants to do business in Texas. And that includes crypto miners.”
ERCOT's own data contradicts the lawmakers' concerns: Bitcoin miners are arguably the only industrial load type that can respond to DR signals in near real-time. Traditional large loads (e.g., data centers) cannot easily curtail, while miners' economic model naturally incentivizes flexibility.
Conclusion: Official Recognition of Mining's Grid Value
The full 22-page ERCOT report is publicly available on its website. This marks one of the first official acknowledgments by a major U.S. grid operator that Bitcoin mining can serve as a valuable demand-side resource. As more states seek price stability and renewable integration, the synergy between cryptocurrency mining and electrical grids may gain broader acceptance.
