Once live, miners can earn up to three separate revenue streams from a single megawatt hour — a 24/7 capacity fee for standing ready, payment for consuming power during negative price events, and Bitcoin mining itself. For some clients running older S19-class hardware, only 10% of income now comes from mining, with the rest from load balancing — at gross margins in the 60-70% range.The conversation covers what it takes to qualify for FCR, mFRR, and FFR markets in the Nordics, why older air-cooled miners often outperform the latest ASICs in these programs, and why GPU/AI compute can't yet replicate this model economically. Jesse and Lukas also dig into the biggest blocker to scaling in Europe — not politics, but capital and perception — and why Gridmetry is already the largest balancing provider by activated hours in Sweden's SE1 zone.They close with a rapid-fire round covering the best EU market for mining (Northern Sweden), why miners make better "batteries" than actual batteries, heat reuse vs. demand response, and Norway's ongoing Bitcoin mining moratorium.TIMESTAMPS:0:00 Intro0:52 Why Gridmetry focuses on Northern Europe1:55 State of the bear market & hash price at $304:07 What Gridmetry does: flexibility-as-a-service explained4:48 Customer economics: demand response vs. heat reuse revenue6:46 Getting paid to be offline vs. mining at 95% uptime7:40 Three revenue streams from one megawatt hour9:03 How integration works for a mining farm10:55 Pricing model & pre-qualification process11:44 Requirements to qualify for demand response markets12:42 FCR, mFRR, FFR markets explained13:23 Preferred miner models (Bitmain, Canaan)14:11 Air-cooled vs. hydro-cooled fleets14:27 Can AI/GPU compute do the same?
