Three utility developments show the same tension from different angles: data centers need reliable power, nuclear upgrades require large capital commitments, and regulators want proof that ordinary customers will not absorb the cost.
Google and Constellation Energy signed agreements covering 3,590 megawatts. A 20-year contract supports 890 megawatts of new nuclear capacity, while a separate 15-year agreement covers 2,700 megawatts of existing output. Constellation plans more than $4.3 billion of investment across six nuclear sites in Illinois, Pennsylvania and New Jersey.
Private contracts and public financing
The Google agreement gives Constellation a long-term buyer for both existing power and uprates. The company says the work will sustain about 4,400 jobs and create roughly 7,200 construction jobs. The central investor question is whether contracted revenue adequately covers project cost, execution risk and delays.
Vistra has a different financing path. The Department of Energy announced a conditional loan commitment of up to $4.2 billion for modernization and uprates at nuclear plants in Pennsylvania and Ohio. The projects would preserve nearly 4 gigawatts of generation and add 433 megawatts.
Conditional is the key word. Vistra must satisfy technical, legal, environmental and financial requirements before definitive documents are signed and funds are disbursed. The commitment can lower financing risk, but it is not cash already received.
Who protects the customer
The proposed $67 billion merger between NextEra Energy and Dominion Energy adds a regulatory test. The companies say customers in Virginia, North Carolina and South Carolina would receive $2.25 billion of shareholder-funded bill credits and that merger costs would not be passed through. Virginia officials and local opponents are asking whether those promises are enough to protect competition and long-term rates.
The Virginia State Corporation Commission is reviewing control of Dominion's regulated utility. The transaction also requires approvals from other state commissions, the Federal Energy Regulatory Commission and the Nuclear Regulatory Commission, and is expected to close in the second half of 2027 if those conditions are met.
For investors, these are not interchangeable catalysts. Constellation has a commercial customer agreement, Vistra has conditional government financing, and NextEra-Dominion faces a contested approval process. The common theme is that AI power demand can support new investment only when contracts, lenders or regulators decide how cost and risk will be allocated.
