Instructions for Finding Supplier Sales Volume

This document provides comprehensive, step-by-step instructions for analysts to identify, verify, and document sales volume for each qualifying supplier-region pair (e.g., from a spreadsheet of utilities/suppliers by country/state). The process is designed for the Granular Registry SSS Reporting platform, aligning with GHG Protocol Scope 2 updates (as of September 13, 2025). Sales volume refers to the supplier's annual electricity deliveries/sales in the region (e.g., GWh or TWh sold to customers), including breakdowns by sector (e.g., residential, industrial, commercial, agricultural), growth trends (e.g., YoY %), peak demand if available, and proportions tied to SSS categories (e.g., volumes under regulated rates for cost recovery). Focus on public data for the most recent years (2023–2025), prioritizing supplier-specific over aggregated data to support SSS emissions allocation (e.g., pro-rata calculations per Scope 2 revisions).

Analysts must process one pair at a time, documenting in a standardized template (see Section 6). Aim for >70% coverage of the supplier's regional sales; flag incomplete data (e.g., seasonal estimates only). Re-evaluate annually or upon events like market reforms (e.g., post-2025 EU Electricity Market Design updates or U.S. IRA extensions). Allocate 2–4 hours per pair, depending on region.

1. Preparation​

  • Review Pair Details: From the spreadsheet, note supplier name, region (e.g., Duke Energy - North Carolina), qualifying SSS categories (from Step 2), and related data (e.g., resource mix or EAC retirements for cross-linkage, such as sales-to-generation ratios).
  • Define Scope: Target retail/wholesale electricity sales (delivered to end-users); include net of losses if specified. Exclude non-electricity (e.g., gas sales) or non-regional volumes (e.g., exports).
  • Gather Tools: Use web browsers, PDF readers, and analysis software (e.g., Excel for trends, Python/Pandas for aggregation if needed). No proprietary tools.
  • Ethical Note: Rely solely on public sources; do not contact suppliers or access paywalled data without approval.

2. Initial Search and Data Identification​

  • Step 2.1: Keyword Formulation: Craft targeted queries, e.g., "[Supplier] electricity sales volume [Region] 2025" or "[Supplier] retail deliveries GWh [Year]". Include variants: "customer sales data", "energy consumption by utility", "annual revenue report" (for volume-derived estimates).
  • Step 2.2: Primary Source Search:
    • Start with supplier's website: Navigate to investor relations, annual reports, or regulatory filings (e.g., search "sales volume report 2025").
    • Check regulatory bodies: E.g., U.S. PUC/FERC for utility data; EU national agencies for consumption stats.
  • Step 2.3: Secondary Database Query:
    • Use global aggregators for context: IEA Electricity 2025 (iea.org/reports/electricity-2025) for country trends; Ember Global Electricity Review 2025 (ember-energy.org/latest-insights/global-electricity-review-2025/) for demand overviews.
    • If supplier-specific unavailable, use as proxy but note limitations.
  • Step 2.4: Explore Alternatives: If initial searches fail, try semantic variations (e.g., "load served" for non-U.S.); check news/academic sources for indirect data (e.g., via Reuters or S&P Global for 2025 forecasts).

3. Regional-Specific Guidance​

Adapt searches to regional data ecosystems; prioritize supplier-level sales where possible.

  • United States:
    • Primary: EIA Electric Sales, Revenue, and Average Price (eia.gov/electricity/sales_revenue_price/) for annual utility sales (2023 data; 2025 release October); Electric Power Monthly (eia.gov/electricity/monthly/) for monthly/rolling data.
    • Forms: EIA-861 (annual sales by utility) and EIA-861M (monthly) at eia.gov/electricity/data.php.
    • Additional: EEI Industry Data (eei.org/resources-and-media/industry-data) for aggregates; State PUC sites for filings.
    • Verification: Cross-check with Annual Energy Outlook 2025 (eia.gov/outlooks/aeo/) for projections.
  • European Union:
    • Primary: ENTSO-E Power Statistics (entsoe.eu/data/power-stats/) for monthly/yearly consumption by country/operator (export as CSV).
    • Eurostat Energy Balances (ec.europa.eu/eurostat/web/energy/data) for sales/consumption; Ember European Electricity Review 2025 (ember-energy.org/latest-insights/european-electricity-review-2025/) for trends.
    • National: E.g., Ofgem (U.K.) or BNetzA (Germany) for utility reports.
    • Note: Post-2025 Electricity Market Design, enhanced demand reporting.
  • China:
    • Primary: National Energy Administration (nea.gov.cn) for provincial sales data; Ember China Energy Transition Review 2025 (ember-energy.org/latest-insights/china-energy-transition-review-2025/) for overviews.
    • Aggregators: CEC (China Electricity Council) reports; IEA China profiles.
    • Challenges: Less supplier-specific; use state-owned enterprise annuals (e.g., State Grid PDFs).
  • India:
    • Primary: Central Electricity Authority Dashboard (cea.nic.in/dashboard/) for monthly/annual sales; MoSPI Energy Statistics India 2025 (mospi.gov.in/sites/default/files/publication_reports/Energy_Statistics_2025/).
    • Additional: POSOCO for grid data; State DISCOM reports.
    • Note: Focus on FY 2024-25 data (April-March).
  • Brazil:
    • Primary: ANEEL (aneel.gov.br) for distribution data; ONS (ons.org.br) for system consumption.
    • EPE (epe.gov.br) for energy reports; Ember for monthly insights (e.g., wind/solar impacts on demand).
  • Australia:
    • Primary: AEMO NEM Data Dashboard (aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem) for regional sales; Quarterly Energy Dynamics (aemo.com.au) for Q2 2025 averages.
    • AER (aer.gov.au) for state data.
  • Other Regions (e.g., Southeast Asia, Africa): Default to IEA/IRENA country profiles; national ministries (e.g., Indonesia's PLN reports). For emerging markets, use World Bank Energy Data (databank.worldbank.org).
  • Global Fallbacks: IEA Global Energy Review 2025 (iea.org/reports/global-energy-review-2025/); Energy Institute Statistical Review (energyinst.org/statistical-review); RFF Global Energy Outlook 2025 (rff.org/publications/reports/global-energy-outlook-2025/).

4. Data Extraction and Analysis​

  • Step 4.1: Extract Raw Data: Download PDFs/CSVs; parse volumes (e.g., GWh by sector). Note units and periods (e.g., fiscal vs. calendar year).
  • Step 4.2: Calculate if Needed: Compute totals/trends (e.g., YoY %: (2025 - 2024)/2024 * 100); use tools like Excel or Python (e.g., df['growth'] = df['sales'].pct_change() * 100).
  • Step 4.3: Link to SSS: Proportion volumes to categories (e.g., 60% residential under customer funding).
  • Step 4.4: Adjust for Context: Normalize (e.g., per capita) or include peaks (e.g., from AEMO dashboards).

5. Verification and Quality Assurance​

  • Multi-Source Cross-Check: Compare at least three sources (e.g., supplier report vs. EIA vs. IEA). Flag discrepancies >5% (e.g., due to net vs. gross metering).
  • Mathematical Validation: Verify totals (e.g., sector sums = overall); perform sensitivity analysis (±10% on trends).
  • Challenge Assumptions: Assume data is accurate—check for revisions (e.g., search "[Supplier] sales correction 2025"). Consider improbables: Weather impacts skewing 2025? Verify via Ember reviews.
  • Triple-Verify: Re-search independently; use alternative methods (e.g., derive from revenue/price if direct unavailable). Document uncertainties (e.g., "Preliminary 2025; full release October").
  • Logical Scrutiny: Review for biases (e.g., underreported EVs in U.S.); seek counter-evidence (e.g., Reuters forecasts). Confirm alignment with GHG Protocol (e.g., consumption-based reporting).
  • Final Reconsideration: After drafting, re-process the pair from Step 2 to confirm no oversights.

7. Risks and Mitigations​

  • Risk: Data Unavailability: Emerging markets lack detail. Mitigation: Use aggregates as proxy; flag and recommend enhanced disclosures.
  • Risk: Inaccuracy/Staleness: 2025 data preliminary. Mitigation: Prioritize latest releases; average with priors.
  • Risk: Regional Variations: Definitions differ (e.g., gross vs. net sales). Mitigation: Standardize per IEA guidelines.
  • Risk: Sectoral Gaps: Incomplete breakdowns. Mitigation: Infer from national shares (e.g., Eurostat).
  • Pitfalls Addressed: Assumed constant growth—mitigated by YoY checks. Logical gaps (e.g., ignoring EVs)—adjust via EEI projections (±20% sensitivity). Oversights (e.g., losses)—include via IEA factors (5–15%).
