Data Centers Struggle to Keep Up with Power Demands
The largest electrical grid in the U.S. has been grappling with an unprecedented surge in data center construction. This has put a significant strain on the grid’s ability to meet the growing power demands of these facilities. The situation has become so dire that the grid’s operator, PJM Interconnection, has announced plans to implement temporary power cuts to prevent widespread blackouts.
Temporary Power Cuts to Begin in June 2027
According to PJM, the power cuts will commence in June 2027 and will specifically target data centers with capacities of 50 megawatts or larger. This decision comes as the grid operator struggles to add new generating capacity to meet the anticipated power needs of data centers.
By 2035, data centers are expected to consume 4 times more electricity than they do today. To mitigate this, PJM is running another auction for new generating capacity. However, the current shortfall in power generation capacity has necessitated the implementation of temporary power cuts.
Data Centers to be Compensated for Power Cuts
Similar to other demand response programs, data centers that experience power cuts will be compensated for the loss. These programs typically provide large users, including manufacturers, with advance notice of the power cuts, ranging from 30 minutes to a few days, depending on forecasted demand.
Customers who have their power cut will be given advance notice, allowing them to take necessary precautions. This will likely include setting up their own sources of on-site power or relying on backup generators, which tend to be costlier to run and frequently more polluting.
Many data centers favor diesel generators since the fuel is widely available and can be stored on-site. Federal regulations allow such generators to be used for up to 50 hours per year for demand response events and up to 100 hours per year for events like emergencies and maintenance.
Vantage Data Centers Under Fire
This week, Vantage Data Centers came under fire for its apparent coordination with Virginia environmental regulators to cast doubt on a report that said diesel backup generators could contribute to tens of millions of dollars in annual health damages for people living near a 96 megawatt data center in Northern Virginia.
PJM has faced criticism in recent months for its management of new generating capacity and large new users, including data centers. The grid operator’s territory runs from Virginia to Illinois, covering 67 million customers. Over the last year, wholesale electricity prices have nearly doubled, and PJM’s independent market monitor blamed data centers for much of the increase.
