The grid cannot cope with the rise in data centers
The US electricity grid is struggling to cope with the surge in demand from data centers, driven by the AI boom, leading to a projected sixfold increase in peak demand by 2030. The US Department of Energy authorized PJM, the regional grid operator, to order data centers in Virginia and Maryland to disconnect and use diesel power during peak strain to prevent blackouts. The issue is exacerbated by slow power plant and transmission line construction, forcing federal orders to keep old coal plants running.
The US electricity grid is facing unprecedented strain due to the rapid growth of data centers, driven by the artificial intelligence boom, which is projected to increase American peak demand by 166 gigawatts by 2030. This surge has led to critical situations, such as a US Department of Energy order enabling PJM, the grid operator for 67 million Americans from Chicago to Washington, to direct data centers in Virginia and Maryland drawing over 50 megawatts to disconnect and run on diesel during grid stress to prevent rolling blackouts.
The article highlights systemic issues in the US energy infrastructure, including a massive backlog of new power plants and transmission lines facing delays from permitting, litigation, and public opposition. These challenges mean only about one in seven proposed power projects are built, often after five years, with transmission lines taking even longer. Consequently, the Energy Department has issued over 40 emergency orders since May last year, forcing old coal and oil plants, like Michigan's J.H. Campbell station, to remain operational past their scheduled retirements, despite local regulators sometimes not seeing an emergency.
This situation has significantly increased the cost of securing grid capacity, with the annual cost in the PJM region rising from $2.2 billion to $14.7 billion in one year, ultimately borne by households. Jim Robb, CEO of the North American Electric Reliability Corporation, describes the mounting risks to grid reliability as a "five-alarm fire," exacerbated by volatile weather patterns. The article concludes that while America isn't short on potential power, it has lost the ability to build the necessary infrastructure, calling for reforms to reward firm power, build regional transmission, and defer plant retirements until reliable replacements are ready.
