A Feb. 2 op-ed, arguing that crypto mining could support Maine’s aging energy grid, overlooks realities. While Bitcoin mines are framed as flexible grid assets, they operate like energy-intensive data centers, with continuous demand and lasting community impacts. Claims that operations can shut down “at the flick of a switch” ignore that profitability depends on running nearly non-stop, adding to an already constrained grid. When cryptominers do power down during peak demand, they are often paid to do so — as in Texas, where Riot Platforms earned millions of dollars in demand response credits.

The proposal to offer cryptominers electricity at 4 to 6 cents per kilowatt-hour raises fairness concerns. Maine households pay about 24 cents per kilowatt-hour, well above the national average. Asking residents to bear some of the highest electricity costs, while extending discounts to a speculative for-profit industry with limited social utility, cannot be justified.

Opposition to proposed AI data centers has already intensified in Maine over electricity costs, water use and infrastructure strain — issues mirrored by crypto mines. 

Nationwide, proof-of-work crypto mining accounts for up to 2.3% of total electricity consumption and could add over $1 billion annually to ratepayer bills. Most of the so-called “stranded energy” it relies on comes from fossil fuels, generating significant carbon pollution. Texas is often cited as a model, yet communities there have experienced soaring electricity rates along with constant noise pollution.

New England cannot afford to repeat this mistake. Energy policy should serve communities, not ask them to absorb the costs of unchecked industries.
