Datacenters boosted prices 75% in largest US energy market
The demand from datacenters has led to a significant increase in wholesale power prices in the largest US energy market. A recent report indicates that prices have surged by 75% year over year, primarily due to the load growth from these facilities. Without timely interventions, the situation is expected to worsen, impacting consumers and the power grid's capacity.
- ▪Wholesale power prices in the PJM Interconnection have nearly doubled in the past year due to datacenter demand.
- ▪The cost per megawatt-hour rose from $77.78 to $136.53, marking a 75.5% increase.
- ▪Monitoring Analytics warns that the current power supply is inadequate to meet datacenter demands and will remain so in the foreseeable future.
