Several headlines precocious described a 25% drop successful bitcoin web trouble during Winter Storm Finn successful January. Most attributed this driblet to curtailment enactment successful Texas. While Texas does correspond 17% of the planetary bitcoin hashrate, ERCOT information shows that immoderate of the curtailment enactment was a operation of higher prices and “good grid citizenship.” In ERCOT, and to a lesser grade successful different ISOs, prices are the champion proxy for grid stress. There are different proxies specified arsenic PRC (physical responsive capability) but prices are a amended measurement for astir situations. For that reason, successful bid to forestall swings successful prices and make much challenging gird conditions, an optimal situation is 1 successful which the terms does not plaything wildly up and down. However, terms volatility is simply a predominant occurrence successful ERCOT, arsenic evidenced by Winter Storm Elliot successful December 2022 (see graph below).
Bitcoin miners are the economically cleanable consumers of electricity. That is not to accidental that bitcoin miners volition devour energy successful an altruistic way, but alternatively that margins for bitcoin miners are uniquely delicate to the terms of powerfulness specified that they are economically incentivized to curtail depletion erstwhile powerfulness prices transcend their breakeven threshold (current breakeven for astir miners ranges betwixt $100 and $200 per MWh). That means they volition devour energy erstwhile prices are beneath their breakeven terms and crook disconnected erstwhile prices are supra it. There are immoderate operational and applicable exceptions to this, for example, if miners person information halfway colocation agreements that stipulate oregon warrant uptime.
Texans should privation bitcoin miners to beryllium connected anytime powerfulness is abundant due to the fact that their accordant depletion incentivizes the buildout of further generation. And little counterintuitively, we people privation bitcoin miners to curtail erstwhile prices are precocious and the grid is nether stress.
That brings america to the January 2024 wintertime lawsuit of the week of January 15th. The headlines would person you deliberation that the Texas grid was again stressed and that bitcoin miners curtailed arsenic a result. The information is overmuch much nuanced. The mean colony terms successful the ERCOT wholesale powerfulness marketplace during the worst 3 days of the tempest was $100.76 per MWh, and prices ne'er exceeded $600 per MWh. For discourse prices max retired astatine $5,000 per MWh. As indicated by wholesale prices, the grid weathered the tempest rather good with ample reserves throughout.
ERCOT did so contented a conservation alert, but that was much of a precautionary connection for powerfulness consumers who don’t show the powerfulness terms each 2nd of each time similar bitcoin miners do.
We did spot immoderate economical curtailment, meaning curtailing powerfulness usage based connected terms signals, from miners for extended periods, and immoderate shorter periods erstwhile the prices exceeded $200 MWh. However, this enactment was little pronounced than successful erstwhile wintertime events oregon summertime vigor waves due to the fact that procreation reserves were much abundant crossed the grid. Some bitcoin miners apt curtailed for longer periods arsenic a motion of bully “grid citizenship,” and to amusement their committedness to a unchangeable grid, but that is hardly quantifiable.
All of this grounds indicates that the trouble driblet past week necessitates a much nuanced explanation. Much of it was a effect of curtailment successful Texas, but aft evaluating ERCOT pricing data, it leads maine to judge that a worldly information of that curtailment came from different ISOs successful North America arsenic well. In short, everyone who has an sentiment astir bitcoin mining curtailment would bash good to ticker ERCOT colony and LMP prices. The information and the economics should signifier the backbone of each aboriginal analyses.
This is simply a impermanent station by Lee Bratcher. Opinions expressed are wholly their ain and bash not needfully bespeak those of BTC Inc oregon Bitcoin Magazine.
