Exelon Corp. executives have significantly trimmed their estimates for data center growth in the utility’s footprint, which spans five states and the District of Columbia. CFO Jeanne Jones told analysts on July 30 that the change is the result of Exelon teams having culled “speculative projects” as part of a plan to set up the company for durable growth. The company’s pipeline of possible future projects, meanwhile, would require about 25 GW of power. “We said, ‘We’re going to study the clusters, we’re going to offer the customer a TSA, sign the TSA and then importantly, put up collateral behind that.’ And so what this update reflects is we have now weeded out speculative projects,” Jones said on a conference call.
