Energy digest — Oct 28, 2026
Top line: Constellation has signed a conditional agreement for up to $5 billion in Department of Energy financing to fund power uprates at eight nuclear plants in Illinois, Maryland and Pennsylvania — the largest federal uprate loan commitment yet, topping Vistra's ~$4.2 billion from October 6. Reactor developer Deep Fission, a DOE-backed startup under fire from a short-seller report, has signed a power agreement in Kansas. Ethiopia's prime minister used a visit to the country's nuclear commission to frame nuclear power as the country's "next chapter," without naming a program.
1. Constellation gets up to $5B DOE loan for uprates at eight plants
What happened: Constellation and the Department of Energy announced on Tuesday, October 27, 2026 that the utility has a conditional loan agreement for up to $5 billion with DOE's Office of Energy Dominance Financing, to support uprate projects at eight nuclear power plants in Illinois, Maryland and Pennsylvania (ANS Nuclear Newswire).
What's genuinely new: the federal-debt layer under utility-side uprates now extends to the largest US fleet operator. DOE's earlier conditional commitment — up to roughly $4.2 billion to Vistra for Beaver Valley, Davis-Besse and Perry, announced October 6 — is the direct precedent; the Constellation deal is larger in headline size and covers eight plants across three states. It stacks on top of the hyperscaler PPA story already in this storyline: Amazon's 20-year underwriting of the Calvert Cliffs uprate and Google's 890 MW, 11-reactor PPA with Constellation, announced October 6, sit on the same uprate program this loan would finance.
Watch: whether the loan closes on the conditional terms, the eight-plant list and per-plant megawatt figures, and the uprate timelines — which this storyline has already flagged as the real bottleneck behind the financing.

2. Deep Fission signs Kansas power agreement as it weathers short-seller fallout
What happened: Deep Fission, a Department of Energy–backed reactor startup, announced last week that it has entered a master energy purchase agreement with the Great Plains Development Authority in Kansas (ANS Nuclear Newswire).
What's genuinely new: the agreement is a new commercial milestone for the company, and it arrives in the week after a short-seller report accused Deep Fission of exaggerating its commercial viability — the coverage explicitly frames the Kansas deal against that fallout.
Watch: whether the master agreement converts into firm purchase volumes and a named deployment, any response from Deep Fission to the short-seller claims, and what the DOE backing amounts to in concrete support.
