Mining curtailment programs
4.2 GW of Bitcoin mining load in ERCOT is the largest curtailable fleet ever assembled
Bitcoin mining operations in ERCOT represent 4.2 GW of interruptible load that can shed within minutes. This is the largest single-purpose curtailable fleet in any grid globally. When summer peaks drive prices above $5,000/MWh, miners earn more by not mining than by mining. The question is not whether to curtail, but when and how much.
The most profitable mining hours are the ones where you do not mine.
Mining curtailment as grid infrastructure
4.2 GW of Bitcoin mining load sits enrolled in ERCOT curtailment programs — larger than most conventional peaker fleets. When grid frequency drops, mining facilities can shed load in seconds, earning $30-45/MWh in ancillary service payments. But the timing decision is binary and consequential: every hour offline costs $40-60K in foregone hash revenue. The difference between profitable curtailment and expensive downtime is measured in minutes of forecast accuracy.
A mining facility that curtails 30 minutes too early loses more than one that never curtails at all.
How AI optimizes mining curtailment decisions
Predict grid stress events
Forecast when ERCOT will approach reserve margin thresholds that trigger high prices. Mining operations need 15-30 minutes of lead time to curtail gracefully without equipment stress.
Calculate curtailment vs mining economics
Real-time comparison of mining revenue (hash rate x BTC price / difficulty) against curtailment value (grid price x capacity). The crossover point shifts by the hour.
Execute graduated curtailment
Not all racks need to come down at once. AI sequences shutdown by efficiency tier, shedding least-profitable hash rate first while maintaining maximum revenue per MW of remaining load.
Optimize recovery and restart
After the price event passes, restart sequencing avoids transformer inrush and minimizes the non-productive period. Fast, safe recovery maximizes mining hours between events.

What we have shipped in this space
Attribution — TS2Vec-Similar Day forecasting
Production system forecasting ERCOT day-ahead prices every 5 minutes. Trained on 2 years of SCED interval data, weather, and transmission constraints.
Our production forecasting system on ERCOT provides the price spike predictions that mining curtailment decisions depend on. When prices move $1,000/MWh in 15 minutes, forecast accuracy is the difference between optimal curtailment and missed revenue.
Curtailment revenue is price forecast accuracy applied to load flexibility.

Common questions about AI in demand response mining
What is the breakeven bitcoin price at which mining curtailment revenue exceeds lost hash rate value?
At $0.06/kWh power costs, a mining operation breaks even on demand-response participation when curtailment payments exceed $500–$800/MW/hour. Below $25,000 bitcoin, lost hash-rate production exceeds demand-response revenue; above $30,000, curtailment economics favor grid participation.
How much power consumption can a mining operation reduce during demand-response events without harming profitability?
Operations can typically shed 40–60% of peak load for 2–4 hour windows while maintaining positive ROI on hardware utilization. Emergency events lasting 6+ hours or requiring 70%+ load reduction create negative economics unless paid at premium rates ($1,500+/MW/hour).
What percentage of a mining facility's revenue can originate from demand response participation versus block rewards?
Demand-response revenue represents 8–15% of total mining facility revenue in markets with frequent high-price events (ERCOT, California). In stable baseload regions, demand response contributes only 2–4% of revenue, making it a secondary income stream.
How quickly must a mining operation shed load to qualify for emergency demand response payments?
Grid operators require response within 5–15 minutes to qualify for emergency demand-response payments at premium rates. Sub-5-minute response requires hardware-level automation and carries technical complexity; slower responses (15–30 minutes) reduce payment qualification significantly. Operations must pre-stage load-shedding capability to minimize response latency.
