Constellation (Nasdaq: CEG), the nation’s largest producer of emissions-free, reliable energy and a leading energy supplier to businesses, homes and public sector customers, and Xpansiv, a leading infrastructure provider for the global energy transition markets, today announced plans to launch clean energy-based annual emission-free energy certificates (EFECs) on an online trading platform.

Xpansiv will further support the emission-free energy market through its North American Renewables Registry (NAR), which will issue nuclear-energy-based zero-emission certificates (ZECs) providing full-lifecycle traceability from issuance to retirement. NAR is a leading renewable energy certificate (REC) registry across the U.S., Canada and Mexico with more than 89 GW of renewable energy capacity.

“As demand for a range of clean, reliable and affordable energy solutions grows, our continued focus is on providing a comprehensive suite of commercial products that help customers meet their environmental goals,” said Jim McHugh, Chief Commercial Officer, Constellation. “We believe the most important energy commodity is a reliable and clean megawatt, and our clean energy resources offer more clean, emissions-free energy than any other energy provider in the U.S.”

“Additional carbon-free power sources are in critical need, and clean energy centers will play a key role in meeting the growing demand for years to come,” said John Melby, CEO, Xpansiv. “Our pioneering launch of clean energy certificate solutions across our registry and exchange demonstrates the power of our comprehensive environmental commodity market infrastructure. We are proud to work with Constellation, the leading reliable, emissions-free energy generator, to achieve this significant initiative for our market.”

With its exchange and registry, Xpansiv is well positioned to support renewed public and private sector interest and momentum in advancing emission-free clean energy generation. These sources, including nuclear, hydropower, solar and wind, are necessary to meet growing electricity needs from existing and new data centers being developed to support artificial intelligence applications, electric vehicles and other sources. According to Goldman Sachs Research, global data center power demand is expected to grow a staggering 160% by 2030.
