======================================================================== GRIDLINQ V2G CASE STUDY SUMMARY ======================================================================== RIVERBEND DRY STACK Indoor dry stack with rack-level circuits — Fort Myers, Florida Rack-level circuits that bill, charge and dispatch A 420-vessel indoor dry stack added rack-level bidirectional circuits, billing maintenance charging by the kilowatt-hour and dispatching stored packs during hurricane-season peaks. ------------------------------------------------------------------------ PROPERTY PROFILE ------------------------------------------------------------------------ Scale: 420 rack positions Service: Three-phase, rack-level branch circuits V2G enabled: 96 rack-level bidirectional circuits ------------------------------------------------------------------------ THE STARTING POINT ------------------------------------------------------------------------ - Maintenance charging for stored electric vessels was unbillable and quietly growing. - Rack rows had no individual circuits, so nothing could be measured or controlled. - The facility needed backup for its stacker and fire system during storm season. ------------------------------------------------------------------------ THE BUILD ------------------------------------------------------------------------ Phase 1: Rack circuit retrofit Ninety-six rack positions received individually metered branch circuits during the summer slow season. Phase 2: Billable maintenance charging Owners are billed per kilowatt-hour for top-offs, turning a cost center into a margin line. Phase 3: Peak dispatch Stored packs above their owner floor are dispatched into afternoon peaks with no impact on retrieval readiness. Phase 4: Storm hardening The stacker, fire pump and building controls sit on an islandable bus backed by aggregated rack capacity. ------------------------------------------------------------------------ RESULTS ------------------------------------------------------------------------ $71k Combined billed charging and program revenue, year one 29% Facility peak demand reduction 6 hrs Stacker and fire system runtime during grid loss ------------------------------------------------------------------------ MEASURED OUTCOMES (BEFORE / AFTER) ------------------------------------------------------------------------ Maintenance charging Before: Absorbed cost After: $38,000 billed / yr Change: cost center to margin Facility peak demand Before: 735 kW After: 522 kW Change: -29% Metered rack positions Before: 0 of 420 After: 96 of 420 Change: +96 circuits Stacker runtime in grid loss Before: 0 hrs After: 6 hrs Change: +6 hrs ------------------------------------------------------------------------ PROJECT ECONOMICS ------------------------------------------------------------------------ Annual value: $71,000 billed charging plus program revenue Capital: $164,000 retrofit, 60% offset by utility incentives Payback: 14 months on the facility's share Time to value: 1 slow season for the 96-circuit retrofit ------------------------------------------------------------------------ "We were eating the charging cost for every electric boat in the building. Now every rack meters, bills and pays us back." — Operations Director, Riverbend Dry Stack ======================================================================== Want this on your property?
