In practice, achieving this requires moving from annual accounting to hour-level evidence that procurement is delivering clean electricity across the load profile. Turning this portfolio goal into operational reality required Microsoft to:

• Establish a baseline of hour-level coverage (share of hours served by zero-carbon power).
• Certify hourly matches with an auditable trail that prevents double counting across markets and instruments.
• Reconcile supply and demand by hour and grid geography while maintaining compatibility with existing contracts and registries.
• Integrate granular proofs with Guarantees of Origin (GOs) for seamless compliance and disclosures.
• Report Scope 2, audit-ready: calculate hourly CO₂ (location- and market-based) aligned with the GHG Protocol, and roll up to annual reports.

Flexidao’s platform matches the hourly consumption of a Microsoft Amsterdam data center with Eneco’s Dutch offshore wind PPA and provides verifiable, registry-compatible proof. The solution:

• Computes an hour-level coverage score by aligning metered production and consumption, hour by hour.
• Issues and registers granular hourly energy certificates (GCs) on blockchain infrastructure to ensure integrity and avoid double counting.
• Aggregates GOs to support annual Scope 2 submissions.
• Calculates hourly CO₂ (location- and market-based) in line with the GHG Protocol.

With Flexidao and Eneco, Microsoft can:

• Monitor and improve hour-level coverage of its CPPA, backed by GCs and GOs.
• Assemble required GOs for annual Scope 2 reporting.
• Report precise hourly emissions, consistent with GHG Protocol Scope 2.

Granular, auditable hour-level coverage moves buyers toward 100/100/0 within current market rules and procurement. It upgrades annual matching to credible hourly evidence that supports grid decarbonization.
