We help customers manage energy market volatility, improve energy efficiency and meet environmental goals by providing tailored energy solutions that deliver the right energy mix while improving reliability. Our direct access to every part

Power 

Constellation is the leading competitive power provider to commercial and industrial customers. We offer commercial and residential customers budget stability and purchasing flexibility, with options for fixed, index and blended pricing solutions, as well as renewable energy supply. Our wholesale electricity supply business provides energy to utilities, municipal co-ops and energy retailers nationwide, managing the sales, dispatch and delivery from Exelon’s portfolio of more than 32,000 megawatts of power generation. 

Natural Gas 

Constellation is among the nation’s top ten largest natural gas marketers, delivering approximately 1,634 billion cubic feet of gas annually to residential, commercial and industrial customers. Our presence in the natural gas market includes trading, transport and storage, physical gas supply, pricing, hedging and risk management. 

Energy Efficiency 

Constellation offers robust programs that help customers achieve comprehensive energy management objectives and meet environmental goals. We develop energy and water conservation projects for commercial customers — often without upfront capital expense — under an energy savings performance contract or as part of an energy supply agreement through Constellation’s Efficiency Made Easy® (EME) offering. In 2018, EME projects implemented by Constellation saved customers more than 80,000 MWh of electricity, preventing more than 36,000 metric tons of carbon dioxide emissions. 

Distributed Energy 

Constellation offers customers distributed energy solutions, through solar, backup generation, co-generation, fuel cells, and battery storage, to help customers more efficiently and reliably meet their energy needs, often without upfront costs as part of a power purchase agreements. These on-site assets allow companies to meet budget and energy resiliency goals, and can help reduce greenhouse gas emissions through installation of low-carbon or renewable assets. 

Constellation Offsite Renewables (CORe) 

Constellation Offsite Renewables (CORe) is a renewable energy purchasing solution designed to provide businesses access to offsite renewable energy projects through the simplicity of a retail power contract. CORe solutions combine location-specific renewable energy purchases and renewable energy certificates (RECs) with a physical

load-following energy supply contract. Constellation also offers the CORe+ product, which supports the development of new build renewable assets, also through a retail power contract. 

Constellation Technology Ventures 

Constellation Technology Ventures (CTV), Exelon’s venture capital fund, drives innovation by researching and investing in emerging energy technologies with the goal of providing new solutions to customers in competitive markets. CTV invests in cutting-edge start-up companies whose emerging energy technologies complement our core businesses and have the potential to transform our industry. 

Driving Customer Choice and Competition 

Constellation is a leading energy industry advocate for competition in the U.S. power and natural gas sectors. We believe that well-designed competitive markets encourage innovation and deliver better results than either traditional monopoly markets or partly restructured markets by providing price transparency, driving investments in generation for reliable electricity supply, and enabling cost-effective development of clean energy sources. Constellation proactively engages with federal and state regulators to advocate for policies that will improve customer choice in the markets in which we operate. 

Community Partner 

Constellation strives to be a model corporate citizen and is committed to giving back to the communities we serve. Our corporate citizenship program focuses on three areas: education, the environment, and community development. As part of our commitment to education, our E2: Energy to Educate Grants support projects that enhance student understanding of the science and technology needed to address energy issues. Through our Community Champions program, residential customers can apply for grants to support causes that are important to their community. Additionally, our partnership with Habitat for Humanity helps reduce energy costs for Habitat families through solar, weatherization and other efficiency solutions.
