Wholesale Energy

Transforming Volatile Markets with Reliability 

In a wholesale energy market, generators compete to sell their output to customers. This competition drives innovation and enhances consumer choice. Wholesale markets also allow for real-time alignment of energy supply and demand in order to keep prices as low as possible and supply steady. 

At Constellation, we leverage wholesale energy markets to help manage market volatility, deliver consistency and efficiency, and help our customers meet their environmental goals. Direct access to every part of the energy value chain enables us to offer innovative, integrated energy solutions and empower customers to make smarter choices.
