======================================================================== GRIDLINQ V2G CASE STUDY SUMMARY ======================================================================== CEDAR POINT BOATYARD Year-round dry storage + service yard — Annapolis, Maryland Winter storage rows that earn instead of idle A 310-vessel storage yard where hulls sit for six to nine months. Stored electric propulsion packs became a winter frequency-response resource. ------------------------------------------------------------------------ PROPERTY PROFILE ------------------------------------------------------------------------ Scale: 310 storage positions Service: Three-phase, upgraded 1200A service V2G enabled: 72 bidirectional storage bays ------------------------------------------------------------------------ THE STARTING POINT ------------------------------------------------------------------------ - Stored electric vessels needed maintenance charging all winter with no way to bill it accurately. - The yard had spare three-phase capacity but no revenue path for it in the off-season. - Nor'easter outages repeatedly knocked out the travel lift and yard lighting. ------------------------------------------------------------------------ THE BUILD ------------------------------------------------------------------------ Phase 1: Service audit GridLinq mapped every storage row against the existing three-phase distribution to find the 72 bays worth electrifying first. Phase 2: Bidirectional bays Storage bays received bidirectional connections with per-vessel state-of-charge floors so owners always return to a full pack. Phase 3: Frequency response Aggregated packs were enrolled in a fast frequency-response product that pays for availability, not just discharge. Phase 4: Islanding The travel lift, yard lighting and service shop were placed on an islandable circuit backed by stored vessel capacity. ------------------------------------------------------------------------ RESULTS ------------------------------------------------------------------------ $44k Off-season availability payments 9 hrs Longest outage ridden through on stored capacity 100% Vessels returned at or above owner charge floor ------------------------------------------------------------------------ MEASURED OUTCOMES (BEFORE / AFTER) ------------------------------------------------------------------------ Off-season electrical cost Before: $31,000 After: $4,200 net Change: -86% Availability payments Before: $0 After: $44,000 / winter Change: new line item Maintenance charging billed Before: Unbilled After: $0.31 / kWh recovered Change: +$16k Outage runtime for travel lift Before: 0 hrs After: 9 hrs Change: +9 hrs ------------------------------------------------------------------------ PROJECT ECONOMICS ------------------------------------------------------------------------ Annual value: $60,000 revenue plus avoided cost Capital: $118,000 service upgrade, 70% program-funded Payback: 11 months on the yard's share Time to value: 1 winter season to full enrollment ------------------------------------------------------------------------ "The boats are here anyway from October to April. Getting paid for capacity that was just sitting in the yard changed how we price winter storage." — Yard Manager, Cedar Point Boatyard ======================================================================== Want this on your property?
