Energy-intensive Projects in NYISO’s Interconnection Queue
Large energy-intensive economic development projects such as data centers, chip fabrication facilities, and traditional manufacturing are driving up demand for electricity in New York. The map above shows the large load projects currently seeking to connect to New York’s grid.
Since 2019, Clean Energy Projects Totaling More Than 14,000 MW Have Completed the Interconnection Process
3,493 MW are under construction
Understanding Real-Time Energy Prices
During periods of extreme weather – like the heatwave in late June – real-time energy prices can rise and fall dramatically. But these prices, shown on the NYISO Markets Real-Time Data Dashboard, don’t necessarily correlate with the number reflected on consumers’ bills.
