Association-owned slips that lower everyone's dues
An owner-association marina with 140 annual slips. V2G capacity now offsets common-area demand charges and backs up the clubhouse during hurricane season.
30 minutes, no cost — pick a time after a few property questions.
Scale
140 annual slips
Service
Mixed 50A, phased pedestal replacement
V2G enabled
58 bidirectional pedestals
The starting point
- Common-area electrical costs were rising faster than the association could raise dues.
- Legacy 30A pedestals could not support the members already arriving with electric tenders.
- Hurricane-season outages left the clubhouse and dock lighting dark for days.
The build
Phase 1
Phased pedestal replacement
Pedestals were replaced dock by dock over two off-seasons so no member lost shore power for a full season.
Phase 2
Member opt-in
Slip holders opt in per vessel and choose their own reserve floor, with revenue split between the owner and the association.
Phase 3
Demand offset
Aggregated discharge is dispatched against the association's own peak window before any grid export is considered.
Phase 4
Storm mode
A single switch puts the clubhouse, pumps and dock lighting on stored vessel capacity ahead of a named storm.
