Institutional dossier
The documented history of Constellation Energy Corporation: chronology, people, research, capital and compute, and governance. Every statement opens its source and its limits.
Records dated 2024-09-20 to 2026-10-06 · 0 undated
5 claims · 4 sources · 5 not editorially accepted. The counts describe this selection. They do not measure completeness or independent confirmation.
Scope, evidence and limits
Description: US power producer (Nasdaq: CEG) and nuclear operator; counterparty to Microsoft, Meta, Google and Amazon agreements here.
The records are grouped automatically. No human inspection of the selected claims, source paths or framing is recorded for this dossier. Each source passage shows how it was checked.
The dossier is computed from existing records. It is not a continuous history of the institution, and a missing record does not mean that an event or relationship did not happen. The chronology uses the dates of events and reports, not the date the public could first have known of them. Later sources can describe earlier events.

Chronology
Records about the institution itself and documented changes to its frameworks, by year. Expand a year to read the claims. People’s other institutional records and related documents have their own sections. Where a date gives only the year or month, the order within it is unknown.
2024Record year · 1 claims
- Constellation announced on 20 September 2024 that it had signed a 20-year power purchase agreement with Microsoft that would pave the way for restarting Three Mile Island Unit 1 as the Crane Clean Energy Center, with Microsoft purchasing energy from the plant as part of its goal to match the power its PJM data centers use with carbon-free energy.Constellation Energy Corporation → has a power agreement with → MicrosoftInspect claim & evidence ↗
Record about this institution · Stated in source · Supported
Stage: contracted · approximate 835 megawatts (as worded: 'approximately 835 megawatts of carbon-free energy to the grid')
Qualification and date notes
Constellation's announcement of a signed agreement; the contract terms and price are not published. The restart required NRC approval (recorded separately) and is not recorded as having occurred. The 835 MW figure is Constellation's wording for energy added to the grid, not a contracted delivery volume; the 2028 online date is a 2024 projection, later restated by Constellation as 2027 (recorded separately).
Signing stated by Constellation in the release; the signature date itself is not given.
2025Record year · 1 claims
- Constellation and Meta announced on 3 June 2025 that they had signed a 20-year power purchase agreement for the output of the Clinton Clean Energy Center in Illinois, 1,121 MW, beginning in June 2027, with Meta purchasing the plant's clean energy attributes.Meta → has a power agreement with → Constellation Energy CorporationInspect claim & evidence ↗
Record about this institution · Stated in source · Supported
Stage: contracted · exact 1,121 megawatts of emissions-free nuclear energy
Qualification and date notes
The power continues to flow onto the local grid; Meta buys the clean energy attributes. A 30 MW uprate is planned. Meta's representative ties the agreement to its AI ambitions; no data-centre site is named.
Date of the announcement, as the source gives it.
2026Record year · 3 claims
- Constellation and Amazon announced on 30 September 2026 a 20-year agreement covering 690 MW of power from the Calvert Cliffs plant in Maryland, including an uprate of approximately 190 MW expected online between 2030 and 2032, with a related retail supply agreement for Amazon operations in PJM.Amazon → has a power agreement with → Constellation Energy CorporationInspect claim & evidence ↗
Record about this institution · Stated in source · Supported
Stage: contracted · exact 690 megawatts of power, including a 190 MW uprate (as worded)
Qualification and date notes
Announced; the uprate is planned capacity. The release says Calvert Cliffs output continues to flow to the PJM grid; it does not name a data-centre site.
Date of the announcement, as the source gives it.
- Constellation stated on 6 October 2026 that it and Google had also entered into a 15-year energy supply agreement for an additional 2,700 MW from Constellation's fleet in PJM.Google → has a power agreement with → Constellation Energy CorporationInspect claim & evidence ↗
Record about this institution · Stated in source · Supported
Stage: contracted · exact 2,700 MWs (as worded)
Qualification and date notes
The release describes this as a financial structure for existing assets; it is not new capacity and the figure is not to be added to the 890 MW uprate figure.
Date of the announcement, as the source gives it.
- Google and Constellation announced on 6 October 2026 a 20-year power purchase agreement to bring 890 MW of new nuclear capacity onto the PJM grid through uprates at 11 Constellation-owned units in Illinois, Pennsylvania and New Jersey, with the first uprate expected by 2028.Google → has a power agreement with → Constellation Energy CorporationInspect claim & evidence ↗
Record about this institution · Stated in source · Supported
Stage: contracted · exact 890 megawatts (MW) of new nuclear capacity
Qualification and date notes
Announced; 890 MW is incremental uprate capacity to be built, not power delivered. The release ties the agreement to Google's 'growth' in PJM, not to a named data centre. The concurrent 15-year 2,700 MW supply agreement is a separate record (recorded separately).
