Microsoft has abandoned data center projects set to use 2 gigawatts of electricity in the U.S. and Europe in the last six months due to an oversupply relative to its current demand forecast, TD Cowen analysts said on Wednesday.

Microsoft Corp. has walked away from new data center projects in the US and Europe that would have amounted to a capacity of about 2 gigawatts of electricity, according to TD Cowen analysts, who attributed the pullback to an oversupply of the clusters of computers that power artificial intelligence.

Microsoft’s retrenchment in the last six months included lease cancellations and deferrals, analysts at investment bank TD Cowen said.
