What is T-EAC?

Temporal Energy Attribute Certificates (T-EACs) are energy certificates with hourly or sub-hourly timestamps that show exactly when carbon-free electricity was produced. For compliance teams, T-EACs give you timestamped proof that renewable supply actually matched demand hour by hour. They're issued by certain registries (with pilots and rollouts increasing as their popularity increases), operating at a finer granularity than but building on the same idea as RECs in North America, Guarantees of Origin in Europe, and REGOs in the UK. Instead of proving renewable energy was generated somewhere during the year, T-EACs prove it was generated in the same hour (or less) that the exact period in time it was consumed.

At time of writing: The Greenhouse Gas Protocol is currently reviewing whether to formally recognise these granular instruments in Scope 2 reporting, though procurement is already happening regardless. The tricky part is that each country runs its own registry with its own data formats, so tracking and cancelling certificates across borders gets incredibly messy very quickly. Soldera connects to multiple registries through a single platform, cutting through most of that friction, therefore being well positioned to handle T-EAC workflows.
