Rapid expansion of data centers, driven by AI and cloud computing, is significantly increasing electricity demand in Maryland and the surrounding PJM grid region. This surge, particularly in Northern Virginia and expanding into Maryland, is forcing higher capacity prices and leading to sharply rising electric bills, with warnings of future rate hikes and potential grid stress.

Data Center Impact on Maryland Electricity
Rate Hikes: Electricity bills for many Marylanders have risen sharply, with forecasts suggesting additional increases as data centers drive up demand. Some estimates warned of potential $70 monthly increases for consumers, driven by, among other factors, the need for increased, expensive grid infrastructure.
Grid Capacity: The PJM Interconnection grid is facing immense strain, with massive new data center developments and a forecasted 32-gigawatt increase in peak load by 2030. This has raised concerns about long-term reliability.
Regulatory Action: Maryland legislators and regulators are considering measures to protect ratepayers, including potential moratoriums on new data center projects until their impact on the grid is better understood.
Infrastructure Costs: While data centers are a massive source of tax revenue and development, they are challenging the traditional energy grid’s capacity, with studies showing power prices in, for example, Baltimore have increased significantly, partly due to increased infrastructure costs, such as the proposed 67-mile high-voltage line
