Wholesale Energy

We Turn Volatile Markets into Reliable Ones

In a wholesale energy market, competing generators offer their output to retailers. Competition drives innovation and consumer choice. Wholesale markets also allow for real-time alignment of energy supply and demand in order to keep prices low and steady.

Wholesale energy markets also help Constellation manage market volatility, deliver consistency and efficiency, and assist our customers in meeting their environmental goals. Direct access to every part of the energy value chain enables us to offer innovative, integrated energy solutions and empowers customers to make smarter choices.

Constellation is the leading source of wholesale energy in the United States for utilities, municipal co-ops, and energy retailers. We take a customer-centric approach, balancing power generation with customer demand to deliver price stability and ensure generation availability through changing market and weather conditions—even during periods of record-breaking temperatures, peak energy use, and power delivery disruptions.

Constellation’s wholesale business supports our generation and customer load obligations with our diverse, low-cost portfolio of more than 32,400 megawatts (MW) of owned generation capacity, powered by the nation’s largest carbon-free energy fleet.

Constellation also is among the 10 largest natural gas marketers in the nation. We manage a robust fuels platform of transport, storage, and supply to serve the demand of our gas-fired generation plants and our customers.

Our wholesale energy trading desk is the third largest in the United States. Constellation traders buy and sell energy from our state-of-the-art 65,000-square-foot trading floor in Baltimore. The desk operates 24/7 and monitors pricing and market activity across North American ISOs (Independent System Operators) and RTOs (Regional Transmission Organizations.)

The trading desk is backed by Constellation’s financial strength and led by a best-in-class team with unmatched technical knowledge. Our team includes energy traders and natural gas traders who manage customer accounts by market region and timeframe; the Generation Dispatch group, which serves as a conduit between our traders, grid operators, and power plants; and meteorologists who provide real-time and long-range weather information to anticipate market demand. Their expertise enables us to maintain a leadership position from which to buy, sell, and monitor the energy marketplace.
