In the summer of 2025, electricity bills across a broad region of the eastern United States have seen notable increases. In cities like Trenton, Philadelphia, Pittsburgh, and Columbus, the typical monthly household bill has risen by between $10 and $27 compared to previous years. The reasons for this increase are directly tied to higher electricity consumption by data centers that support artificial intelligence applications and cloud services.
According to PJM Interconnection, the nation’s largest power grid operator, energy consumption has risen significantly this summer in the region it oversees, which includes 13 states and the District of Columbia.
The operator has reported that some areas may see bill increases of up to 20%.
The primary cause is the increased demand for electricity from data centers that process large volumes of information for tools like ChatGPT, backed by companies such as Google, Meta, Microsoft, and Amazon.
Demand for electricity from these centers has grown considerably since 2023, when the widespread use of artificial intelligence systems became popular. In just one year, data centers housing these technologies have come to consume up to thirty times more energy than conventional ones. This phenomenon has led to the cost of expanding the power supply being spread among all users connected to the grid, including households and small businesses.
Data Centers Have Driven Up Electricity Prices
Data centers have spurred unprecedented increases in energy demand in densely populated regions. The rise in demand from these centers accounts for roughly three-quarters of the increase in grid “capacity” prices, according to a report by independent monitor Joseph Bowring. The annual capacity price auction in the PJM region showed an 833% increase last year, the effects of which are now reflected in consumers’ monthly bills.
In Columbus, for example, households with the standard rate from local utility AEP Ohio have seen their bills rise by about $20 per month since June; this amounts to an annual increase of $240, based on company and independent monitor data. The increase has been directly attributed to the “boom” in data centers, which require ensuring sufficient power to cover their peak demand.
Industry companies, grouped under the Data Center Coalition, have publicly defended that they pay the full price for electricity service, although recently energy regulators in Ohio determined that these centers must bear a higher cost to fund the infrastructure upgrades needed to meet their demands. Following the decision, the association expressed its “disappointment” in a statement but emphasized its commitment to covering the corresponding expenses.
Energy Demand Could Exceed 154,000 Megawatts
The increase in energy consumption by artificial intelligence and cloud computing has not only raised prices in the capacity market but has also strained the existing electrical infrastructure.
The system operated by PJM serves 67 million customers and could reach summer demand peaks exceeding 154,000 megawatts, with the potential to surpass all historical records if intense heatwaves occur. Residential users have been warned of increases of $25 or more in their monthly bills, while commercial users should expect increases of up to 30%.
States like Virginia and Ohio have promoted the installation of data centers through tax exemptions, allowing the purchase of equipment without paying sales taxes, which has encouraged the proliferation of high-consumption technology facilities. While these policies have created jobs, organizations and residents have expressed concerns about bearing the cost increases, fearing that demand may outstrip supply and trigger further price hikes.
Why Is the Energy System in Crisis?
The energy generation capacity is struggling to keep up with demand growth. Many fossil fuel plants are closing due to state regulations, aging infrastructure, or market changes. More than 9,000 megawatts of coal capacity will be retired or converted to gas in 2025. Renewable alternatives like solar and wind energy face obstacles due to regulatory delays, cost overruns, and cuts in federal incentives.
Excess demand could exceed the 166,000 megawatts available in the PJM grid, creating a risk of shortages in extreme situations. As a result, “demand response” programs have been implemented, offering payments to companies that temporarily reduce their electricity consumption to avoid rolling blackouts. Nevertheless, pressure on the system persists.
The popularity of applications like ChatGPT has multiplied the use of artificial intelligence in daily operations, generating an unprecedented energy demand. A single high-definition image generated by AI can require as much energy as charging a smartphone halfway. Abe Silverman, a researcher at Johns Hopkins University, explained that all regions of the country are experiencing significant growth in data center-related load, which is driving up prices for both transmission and power generation.
