Accounting for Transacted Timestamped Information
Market participants have developed a range of interim approaches to enable buyers to transact time-stamped certificates and associated hourly information to better align with their hourly load and meet emerging Greenhouse Gas Protocol and Science Based Targets initiative standards. However, there is an urgent need for clear, credible best practices for trading and claiming the time-stamped (including hourly) information associated with these transactions.
This initiative will identify best practices for accounting for transactions involving time-stamped hourly information to ensure integrity, transparency, and access in voluntary and compliance markets. Outputs may include recommendations and requirements for companies, EAC marketers, utilities, regulators, and tracking systems.

Background Reports

Accounting for Transacted Timestamped Information
Corporate buyers are increasingly aiming to match their clean energy consumption with generation on an hourly basis, but fully timestamped hourly Energy Attribute Certificates (EACs) are not yet available at scale. In the interim, market participants are transacting hourly generation information through a variety of emerging methods that work within existing EAC infrastructure, each with different implications for claims integrity and double-counting risk. This background report summarizes these approaches, current tracking system capabilities, and key market players. The goal is to inform working group sessions for the Accounting for Transacted Timestamped Information CEAP initiative and subsequent guidance development.
