# Gridpol > Gridpol prepares and files utility interconnection applications for licensed solar PV, battery storage and EV charger installers in the United States: pre-submission check, single-line diagram, site plan, homeowner e-signature, filing in the installer's utility portal accounts and follow-up to permission to operate (PTO). Gridpol Unlimited: $500 per month, unlimited applications, 12-month agreement with Stage Strategy USA, Inc.. Applications are typically submitted within 2 business days after complete documents. Gridpol is a paperwork and submission service, not an electrical contractor. We do not install, design for construction or sign as the contractor. Every application is filed in the name of the licensed installer, with the installer’s license number, and in the customer’s name as the utility account holder. We act only as the installer’s authorized representative, using the installer’s utility portal accounts and the customer’s signed authorization where the utility requires it. Not included: building/electrical permit plan sets, PE-stamped drawings, utility fees. ## Data - 2906 US distribution utilities from U.S. Energy Information Administration, Form EIA-861 Annual Electric Power Industry Report, data year 2025 (Utility_Data, Service_Territory, Sales_to_Ultimate_Customers, Delivery_Companies, Net_Metering) - 33791 ZIP codes mapped via U.S. Census Bureau, 2020 ZCTA to County Relationship File (tab20_zcta520_county20_natl.txt); share = land-area share of the ZCTA in each county - 204 utilities with a researched interconnection process (official utility and commission sources), 149 fully verified ## Pages - https://gridpol.com/how-it-works - https://gridpol.com/what-we-file - https://gridpol.com/pricing - https://gridpol.com/utility-lookup - https://gridpol.com/utilities - https://gridpol.com/sample-drawings - https://gridpol.com/faq Contact: info@gridpol.com
