Advancing Innovation


We provide customers with reliable, clean energy and access to diverse energy products and services that are integral to supporting a clean and reliable energy economy.

We are at the leading edge of developing promising carbon capture and sequestration technology, which creates a pathway that could help the U.S. sustainably transition to a clean energy future by offering the potential to decarbonize the nation's natural gas generation. 

We are also exploring how our existing nuclear sites and our team's expertise can catalyze the building of additional nuclear resources by working with diverse stakeholders to evaluate how we can support new nuclear development. Existing nuclear sites that supply reliable, clean energy are ideal for new nuclear development given site attributes, community support, infrastructure and customer demand. Investing in new nuclear development at existing sites can support load growth from the data economy, AI and industrial development.

To support these innovative offerings and services, Constellation continues to work closely with our customers, suppliers, universities, governments, national labs and startups to develop and invest in new technologies.

Sustainable Business Strategy


Our Commitment to Clean, Reliable Energy

At Constellation, we are building the clean, reliable energy capacity of tomorrow while generating power to meet the demands of today. By "clean" or "emissions-free," we are referring to electricity generated by facilities that do not directly emit greenhouse gases, such as carbon dioxide or other air pollutants during the generation process.

As the largest energy producer in the U.S., we operate a fleet of zero-emission nuclear, hydro, wind, solar and geothermal facilities as well as dispatchable low-emission natural gas plants. Constellation provides about 10% of the total clean power in the U.S. and continues to invest in our energy assets and new technologies to expand clean energy on the grid by increasing output, restarting operations or renewing licenses for existing clean energy centers.

Constellation is accelerating the transition to a clean, reliable energy future for America. Our strength comes from our position as a leading supplier of energy solutions that help customers manage their energy use, improve efficiency and match their consumption with emissions-free energy. We offer a full suite of products and services, such as energy efficiency solutions, on- and off-site clean energy and storage options, energy management tools, GHG monitoring and reporting and  other services to help businesses meet their operational and sustainability goals.

We are prepared to meet the accelerating demand for cleaner, more reliable and sustainable energy sources and to lead the way in meeting customers' needs and expanding access to clean energy.

CLEAN ENERGY

Why is Clean Energy Important?

Our world depends on the energy we produce. Clean energy generation provides the power we need while reducing greenhouse gas emissions and helping mitigate the worst effects of climate change.
 

What are greenhouse gases? Greenhouse gases are pollutants that trap heat in the Earth's atmosphere. Reducing our carbon footprint and using more clean energy sources helps us limit the impacts of climate change and protect the planet for future generations.
 

The conversation around clean energy is often limited to wind power and solar energy. However, there are other types of clean energy beyond wind turbines and solar panels. Clean energy can also be sourced from nuclear resources, geothermal and even water. Clean energy examples include:

Nuclear energy is traditionally generated through a process called nuclear fission. Atoms are split apart to form smaller atoms, creating heat. The heat that’s created is then used to boil water into steam, which powers an electricity-creating turbine. It’s one of the most reliable sources of emissions-free energy available. 

Hydroelectric energy, or hydropower, is created using the force of running water. As the water moves, it spins the blades in a turbine, which then powers the generator that produces energy. Hydropower also offers benefits beyond electricity generation, supporting flood control and irrigation.

Solar energy works by using solar panels to absorb and trap sunlight. An inverter then converts the sunlight into AC electricity. 

Wind is another abundant and easy-to-access energy source. To create wind energy, air flows across the blades of large turbines, causing them to rotate. That motion is harnessed and converted into electricity.

Geothermal energy is produced using heat from within the Earth's core. Wells are drilled into the ground, which enables water to recirculate through wells to generate steam. The steam is then used to power turbines that generate electricity.

What are Clean Energy Centers?


A clean energy center is where one or more clean, zero-carbon emission power generation resources may be contracted with customer load.

Each Constellation nuclear station is a clean energy center. Our clean energy centers have the potential to expand and go beyond their roles as baseload energy sources and providers of grid capacity.

At Constellation, we invest in our facilities and have a commitment to expanding the capabilities of these clean energy centers. This innovative model satisfies the growing demand for clean and reliable energy. By design, our clean energy centers are located near water, transmission infrastructure and transportation hubs, making them ideally suited to be centers of clean energy production.
