The following is a guest post by Ryan Condron, co-founder of Lumerin, a Bitcoin hashpower marketplace.
Microsoft is building huge AI data centers in Arizona and Wisconsin to provide the infrastructure for powering this transformational technology. And AI is hot — literally.
Such data centers put a severe strain on power grids by requiring vast amounts of electricity. By 2026, one estimate forecasts AI will consume about 40 gigawatts (GW) of the projected 96 GW in global power demand from data centers, up from a total demand of 49 GW in 2023. This energy use generates a lot of heat and requires a lot of water to cool down data servers. With an estimated usage of 56 million gallons of water a year from Microsoft's data center in Goodyear, Arizona alone, the local desert communities risk running out of water to accommodate their new power hungry neighbors.
On the other hand, while often criticized as an “energy hog,” Bitcoin mining is actually an amazing way to help make power grids more stable and efficient. This is due to a Bitcoin miner’s ability to adjust energy usage in near real-time.
To keep a power grid at the correct frequency, grid operators must “balance” the power grid by adjusting energy production to match user demand. This process is called “load following.” Historically, increasing and decreasing energy production was the only real-time response action grid operators had available to them. But now, during periods of high or low electricity demand, Bitcoin miners can quickly adjust their power consumption to create a second, real-time response action that grid operators can use to establish balance.
Since renewable energy production fluctuates with the weather and is difficult to ramp up or ramp down to establish grid balance, Bitcoin mining is proving to be a scalable and economically feasible variable load solution. This new grid balancing pattern, made possible through Bitcoin mining, has now paved the way for use by new, larger and less flexible AI power consumers.
But why can't AI simply adjust its energy usage in real-time also? Bitcoin miners’ energy usage has a unique aspect compared to AI data centers. The Bitcoin network is a constant customer that is not adversely affected by miners throttling down or turning off their equipment. However, if an AI data center turns off some of its servers to throttle down AI compute, customers are adversely affected.
This flexibility makes Bitcoin mining an effective way to stabilize power grids – especially in helping manage electricity consumption from large AI data centers – because it can quickly respond to fluctuations in electricity supply and demand.
