The Power Emissions Certificate (PEC) registry is designed to integrate seamlessly with existing Renewable Energy Certificate (REC) registries to enhance carbon accounting transparency and improve the operational efficiency of renewable energy procurement. This integration is essential for ensuring that environmental attributes associated with carbon-free energy (CFE) generation are accurately represented without double-counting, and that PECs provide additional value through enhanced data on carbon emissions reductions.
In this configuration, Power Emissions Certificates (PECs) are issued based on RECs that have already been retired in the end user's REC registry account. This approach is ideal for companies or organizations that have entered into operational Power Purchase Agreements (PPAs). Since the RECs are already retired, the environmental attributes associated with the renewable energy have been claimed, and PECs can then be issued without the need to modify or interact further with the REC registry.
PECs will be registered in the PEC registry under the same end user, providing additional data layers for emissions tracking, such as the marginal emissions reductions achieved by the associated renewable energy project. This configuration maintains simplicity, avoiding operational risks or complexities by ensuring that REC management processes remain unchanged while still allowing for advanced carbon accounting capabilities.
Key Benefits:
Minimal Complexity: No changes to the REC registry are required.
Risk Reduction: Since no further transfers or retirements occur in the REC registry, this method avoids operational risks.
Operational PPA Fit: This approach suits organizations already retiring RECs under existing PPAs.
Transparency and Data Enhancement: The PEC registry adds emissions data without complicating REC transactions.
This second configuration involves transferring active RECs from a local REC registry to the PEC Registry trading account. Once the RECs are transferred, they are either canceled or retired within the PEC registry, allowing for the issuance of PECs. This configuration is particularly suitable for organizations purchasing unbundled RECs, as it enables the environmental attributes of the RECs to be integrated directly into the PEC registry and claimed by the end user.
By managing both REC retirement and PEC issuance within the PEC registry, this approach offers comprehensive tracking and transparency, ensuring that the environmental claims related to the energy are clearly linked to specific emissions reductions. After PEC issuance, the end user can claim the environmental attributes of both the REC and the associated emissions reductions, reflecting the grid’s carbon intensity at the time and place of energy generation.
Key Benefits:
Comprehensive Emissions Tracking: Allows for enhanced transparency by tracking both REC and PEC attributes within the PEC registry.
Ideal for Unbundled RECs: Ensures the environmental attributes of unbundled RECs are transferred, retired, and tracked within a single system.
Imported RECs: RECs effectively become part of the PEC registry, enabling users to claim both energy and emissions attributes.
Enhanced Corporate Carbon Accounting: Enables companies to align energy procurement with emissions reduction goals more precisely, supporting advanced carbon accounting strategies such as 24/7 matching.
Both configurations enhance renewable energy procurement through the PEC registry by offering flexibility, transparency, and advanced carbon tracking capabilities. These integrations ensure that organizations can adopt PECs without disrupting their existing REC strategies while gaining access to more precise carbon accounting data to meet sustainability objectives.
