How Much Does It Cost to Run a Crypto Mining Rig in California? (2026)

A mining rig runs flat out around the clock. Even a single-GPU setup at 500 watts uses more electricity than most whole households, and an ASIC miner at 3,000 watts uses as much as a dozen fridges.

A typical crypto mining rig (1,500 W) costs $0.52 per hour, or about $378.00 per month at 24 hours a day in California. Expensive to run

Electricity price region Hours used per day

Wattage	Per hour	Per day	Per month	Per year
Low (500 W)	$0.17	$4.20	$126.00	$1,533
Typical (1,500 W)	$0.52	$12.60	$378.00	$4,599
High (3,500 W)	$1.22	$29.40	$882.00	$10,731

Formula: watts ÷ 1000 × hours × price per kWh. Typical use is 24 h/day ≈ 13,140 kWh per year.

In California, with electricity at $0.35 per kWh (source: EIA Table 5.6.A, 2026-06), a typical crypto mining rig costs $0.52 per hour and about $4,599 per year at 24 hours a day. That is about 94% more than the US national average of $194.40 per month, because electricity in California costs $0.35 per kWh against $0.18 nationally. Each $1.00 of electricity buys roughly 1.9 hours of use.

How to lower the cost of running a crypto mining rig

Calculate the electricity cost per day before anything else. It decides whether mining makes money at all.
Undervolt GPUs. It often cuts power by 20 to 30 percent with little hash rate loss.
Vent the heat outdoors in summer. Cooling the room adds to the bill.
