Why SSS
Built for Carbon Accounting Integrity
SSS makes legacy utility clean energy visible and auditable for buyers who already fund those resources through bundled electricity rates.
Claim What You Pay For
Attribute default carbon-free generation from utility standard supply using pro-rata allocation based on load share.
Audit-Ready Evidence
Supplier attestations, public compliance data, and reproducible calculations with clear provenance for every reported value.
Anti-Shuffling Controls
Prevent double counting and leakage by separating default-supply attributes from unbundled EAC transactions.
Methodology Transparency
Public documentation explains assumptions, boundaries, and treatment of verified vs proxy data.
