ATTACHMENT 7 PRELIMINARY EXHIBIT 1.xlsx

This is a preliminary account listing spreadsheet that documents natural gas supply accounts for which GSA plans to conduct competitive auctions in Fiscal Year 2026. The file contains detailed account-level information organized by state and utility provider, including utility account numbers, tariff rates, contract start months, service addresses, billing types, and annual consumption volumes measured in Dths (dekatherms). The spreadsheet encompasses approximately 120 accounts across 25 states, serving multiple federal agencies including the Department of Veterans Affairs, Bureau of Prisons, USDA, NASA, EPA, Department of Energy, and others. Consumption volumes range from minimal amounts (41 Dths annually) to substantial industrial usage (345,325 Dths at NASA's Glenn Research Center).

The accounts are designated as either existing GSA Retail Choice accounts or new accounts, with contract start dates ranging from June 2026 through February 2027. All accounts are marked as dual fuel or firm service arrangements with specific utility providers such as Unisource Energy Services, Pacific Gas & Electric, SoCalGas, Atmos Energy, and regional natural gas distributors. The GSA Contracting Officer Mark West and NGAP Account Manager Erica Martunas are identified as the primary contacts. This preliminary exhibit serves as a baseline reference document, with GSA noting that updated final Exhibit 1 files will subsequently be released containing confirmed auction dates, EnelX RFP numbers, final auction end times, pricing product specifications, contract terms, and revised account information including monthly usage data. Daily usage data will not be provided for any accounts in the auction process.
