Data Centers Could Add to Your Electricity Costs as Winter Arrives
As Americans prepare to turn on their heat, some households are already paying more for electricity because of growing demand from data centers.
The added expense is reaching family budgets. Electricity market researcher Sanya Carley attributed at least $10 a month in additional household electricity costs in western Maryland and Ohio to data centers, beginning in mid-2025. That is money families must find before accounting for any additional electricity needed during cold weather.
Data centers house the computers behind online services and artificial intelligence. Their growing appetite for power is putting pressure on electricity supplies. Energy company Exelon acknowledges that data centers and the increased use of AI are increasing electricity demand and can drive up costs. It also explains that higher electricity supply costs are passed through to customers.
The connection matters especially for households using electric heat. A higher electricity rate means paying more for the same amount of power. When cold weather makes the heating system run longer, the expense can grow further. Duke Energy explains that extended cold causes heating systems to work longer to maintain indoor temperatures.
The impact varies by region. Reporting identifies the PJM electricity market, which serves parts of the Midwest and Mid-Atlantic, as an area where data centers have contributed to higher bills. They are one of several pressures on electricity prices, alongside fuel costs and investments in the power grid.
For families already stretching each paycheck, those added costs leave less room for groceries, transportation and other necessities as winter arrives.
Tips for keeping your heating bill low this winter
Keep the thermostat at the lowest comfortable setting. Avoid heating your home more than necessary.
Seal drafts around windows and doors. Weatherstripping and caulk can help keep warm air inside.
Check your air filter regularly. Replace it when dirty so the heating system can work efficiently.
Use sunlight for warmth. Open curtains on sunny days and close them at night.
