The Vindicator explains: Data centers added billions to the cost of keeping New Jersey's electric grid reliable
Data centers are significantly increasing electricity costs in New Jersey and the broader PJM Interconnection region, accounting for billions in capacity auction costs. This has led to over two dozen municipalities in New Jersey, including Mansfield and Neptune Townships, banning data centers, while New York has enacted a one-year moratorium to develop new regulations. State and national leaders are now debating solutions to the grid strain and rising costs.
The independent market watchdog for the regional power market, Monitoring Analytics, reports that warehouses of computer servers powering AI and cloud computing are driving up electricity costs in New Jersey and across the Mid-Atlantic and Midwest. Joseph Bowring, President of Monitoring Analytics, stated that data centers accounted for an estimated $6.3 billion, or 38%, of the costs from PJM Interconnection's most recent capacity auction, which are ultimately passed on to electricity customers. Over the past four auctions, data centers have been responsible for an estimated $29.4 billion in capacity costs.
The rapid growth in electricity demand, primarily from data centers, is straining the regional electric grid, requiring PJM to buy more reserve power. Despite capacity auction prices hitting their maximum of $325 per megawatt-day, the grid still fell 6.8 gigawatts short of its reliability target. Developers face significant hurdles in building new power plants, including lengthy permitting, environmental reviews, interconnection studies, and rising costs.
In response to these concerns, over two dozen municipalities in New Jersey, including Mansfield Township and Neptune Township, have approved bans on data center development due to their impact on the environment, water supplies, and electricity costs. New York Governor Kathy Hochul recently signed an executive order establishing a one-year moratorium on new large-scale data centers seeking certain state environmental permits. This pause aims to allow New York to develop a regulatory framework to protect consumers from higher costs, safeguard the power grid, reduce environmental impacts, and assist local governments in evaluating future data center proposals.
Environmental groups have urged New Jersey Governor Mikie Sherrill to implement a similar moratorium, and U.S. Representative Frank Pallone, Jr. has called for a nationwide moratorium, emphasizing that families should not face increased power bills because of data centers. State officials, utilities, consumer advocates, and environmental organizations across the PJM region are actively debating how to fund the necessary new infrastructure to support this demand growth.
