Constellation and Xpansiv Begin Trading Emission‑Free Energy Certificates on Dec 2

Updated Published Cached

Constellation and Xpansiv launch EFEC trading on Dec 2 – they will list annual emission‑free energy certificates from Constellation’s PJM clean‑energy centres on Xpansiv’s CBL spot exchange starting 2 December, with hourly certificates planned later [1].

Constellation claims status as US’s largest emissions‑free producer – the utility says it operates the nation’s biggest nuclear fleet and will provide certificates representing one megawatt‑hour of nuclear‑generated power from its clean‑energy centres [1].

Xpansiv’s North American Renewables Registry adds traceable ZECs – the registry will issue nuclear‑energy‑based zero‑emission certificates that track from issuance to retirement, leveraging a platform that already covers over 89 GW of renewable capacity in North America [1].

EFECs give businesses a quick path to lower emissions – unlike on‑site renewables, firms can purchase certificates matching all or part of their electricity use, accelerating claims of reduced carbon footprints [1].

Industry leaders stress growing demand for clean megawatts – Constellation CCO Jim McHugh says the company offers a “comprehensive suite of commercial products” to meet environmental goals, while Xpansiv CEO John Melby highlights the critical need for carbon‑free power and the market infrastructure’s role [1].

  • Jim McHugh, Constellation Chief Commercial Officer – “We are focused on providing a comprehensive suite of commercial products that help customers meet their environmental goals… 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 US.” [1]
  • John Melby, Xpansiv CEO – “Additional carbon‑free power sources are in critical need, and clean energy centres will play a key role in meeting the growing demand for years to come… our pioneering launch of clean energy certificate solutions across our registry and exchange demonstrates the power of our comprehensive environmental commodity market infrastructure.” [1]
