Constellation & Xpansiv Launch Clean Energy Trading Platform

Constellation, the nation's largest producer of emissions-free energy, and Xpansiv, a leading infrastructure provider for global energy transition markets, have announced a groundbreaking partnership to launch clean energy-based annual emission-free energy certificates (EFECs) on Xpansiv's CBL spot exchange beginning December 2, 2025. This collaboration represents a significant advancement in environmental commodity trading, with Constellation offering EFECs sourced from its clean energy centers in the PJM region. The partnership extends beyond initial offerings, with plans to introduce hourly EFECs in the future, providing unprecedented granularity in clean energy tracking and trading.

The initiative leverages Xpansiv's comprehensive market infrastructure, including their North American Renewables Registry (NAR), which will issue nuclear-energy-based zero-emission certificates (ZECs) with full-lifecycle traceability from issuance to retirement. NAR stands as a leading renewable energy certificate registry across the U.S., Canada, and Mexico, managing over 89 GW of renewable energy capacity. Key executives from both companies emphasized the strategic importance of this collaboration, with Constellation's Chief Commercial Officer Jim McHugh highlighting their focus on providing comprehensive commercial products to help customers meet environmental goals, while Xpansiv CEO John Melby underscored the critical need for additional carbon-free power sources and the role of clean energy centers in meeting growing demand.

This partnership arrives at a crucial moment in the global energy transition, addressing the surging electricity demands driven by artificial intelligence applications, electric vehicles, and new data center development. According to Goldman Sachs Research, global data center power demand is expected to grow by a staggering 160% by 2030, making reliable, emissions-free energy sources increasingly vital. The companies will host a webinar on Wednesday, November 12, featuring experts including Whitney Boles from Constellation and Katie Doyle and Russell Karas from Xpansiv, to provide insights into how verified, registry-issued certificates support decarbonization programs and disclosure requirements. This initiative positions both companies at the forefront of the evolving energy marketplace, combining Constellation's massive clean energy generation capacity with Xpansiv's sophisticated trading and registry infrastructure.
