Constellation Energy
What are their main businesses and subsidiaries?
Constellation Energy is a major energy producer in the United States, with 32,400 MW of generation capacity. Constellation Energy proudly claims that they are the #1 producer of carbon-free energy in the United States, producing 10% of the nation's carbon-free capacity. Constellation Energy is an extremely large producer of nuclear power, producing more nuclear capacity than 'all other competitive generators combined', according to their 2024 investor presentation (22.1 GWs!).
Constellation's main business (pre-Calpine merger), has been located in the PJM (Pennsylvania-New Jersey-Maryland) Interconnection (69%), with most other generation occuring in the ERCOT and NYISO regions (9#% total). Following their acquisition of Calpine, Constellation Energy has a more rounded service area, producing 49% of its total capacity in PJM, 23% in ERCOT, 10% in CAISO, 8% in NYISO, with a final 10% distributed in other locations.
What is the total installed generation in MWE owned or operated?
Constellation has a total of 32,400 megawatts of capacity.
What are the types and MWE of power plants they own or operate?
According to Constellations Investor website, the breakdown of their fleet is as follows:
| Plant Type | Capacity (%) | Capacity (MW) |
|---|---|---|
| Nuclear | 60 | 19,440 |
| Natural Gas | 20 | 6,480 |
| Natural Gas and Oil | 6 | 1,944 |
| Hydroelectric | 5 | 1,620 |
| Oil | 4 | 1,296 |
| Wind | 1 | ~324 |
| Solar | 1 | ~324 |
Which of their plants are owned and operated as merchant plants and which are regulated?
!
According to the location of Constellation's generating plants, most of their
plants are located in merchant areas. All of Constellation Energy's nuclear power plants are in deregulated (merchant) markets. They have several wind facilities in regulated locations, while owning one gas plant in a regulated state (Alabama).
What does their strategic plan say?
Constellation's strageic plan is to continue to build towards a carbon-free future--at least that is what it says on their website. Their actions, however, show a possibly different way forward following the acquisition of Calpine, the United States's largest power generator from natural gas
What are the major risks or challenges they face in the next 10 years?
In my opinion, Constellation's biggest risk is they do not have any current plant construction, but expect energy demand to increase dramatically. They are in are in great position to capitalize on increased energy demands from the development of AI, but really only through increased prices. Most of their capacity is located in merchant markets which is great for their profitability in a high demand market, but if they stay focused on nuclear they have to start building yesterday.
Dominion Energy
What are their main businesses and subsidiaries?
Dominion Energy operates its business through three main companies: Dominion Energy Virginia, Dominion Energy South Carolina, and Contracted Energy. Dominion Energy's main business is in wholesale energy, but Dominion makes a significant amount of money by doing natural gas distribution, transmission, and storage.
What is the total installed generation in MWE owned or operated?
Dominion Energy's total installed generation capacity is hard to find. Fo
