Commercial Solar and Battery Storage for the U.S. Virgin Islands

WAPA rates are among the highest in the United States and the grid still drops. AGT builds hurricane-rated solar and battery systems that let resorts, manufacturers and large properties generate and store most of their own power, designed and shipped from Florida by a U.S. licensed EPC.

  • Self-consumption solar + battery designs built for WAPA's Net Energy Billing rules
  • Engineered to Florida's High-Velocity Hurricane Zone standards, built for Irma- and Maria-class storms
  • Batteries that carry critical loads through WAPA outages without a generator start
  • One contractor for solar, storage, electrical and the roof underneath

Why USVI operators are moving now

Three problems, one system

Operating on St. Thomas, St. Croix or St. John means paying some of the highest electricity rates in the country for power that isn’t always there. These are the three problems every operator raises.

The most expensive power in the U.S.

At 40¢+ per kWh, a resort or plant's electricity line item is two to three times what a mainland competitor pays. Solar produces power on your own roof for a fraction of that, fixed for 25 years.

Outages are routine, not exceptional

WAPA load shedding, feeder faults and generation shortfalls happen in normal weather. Batteries pick up critical loads instantly, and your generator becomes the backup to the backup.

Irma and Maria set the design standard

Two Category 5 storms in two weeks in 2017. Any system installed here has to be engineered for that, and it has to come with a shutdown, inspection and restart plan your team can run.

What you’re paying today. WAPA’s commercial tariff has run in the 40–47¢ per kWh range in recent years, including the LEAC fuel surcharge. That is roughly three times the U.S. mainland commercial average. Figures are from public utility and regulator sources; we verify your actual tariff from your bills.

Interactive estimator

Size a solar + battery system for your facility

A first-pass estimate from your monthly WAPA bill. It tells you roughly how much solar fits, how large a battery you need to carry critical loads through an outage, and what that offsets. Our engineers refine it with your interval data.

Estimates only. Assumes about 1,500 kWh per kW per year of production, 95 sq ft per kW of roof area, 90% usable battery capacity and a 30% peak factor. Final sizing depends on your interval data, roof structure, utility tariff and interconnection limits.

Who we build for in the U.S. Virgin Islands

Built for facilities where downtime has a price

Commercial and industrial properties with a meaningful energy bill and loads that can’t wait for the grid to come back.

Resorts & hotels

St. Thomas, St. John and St. Croix properties with large daytime cooling, laundry and pool loads that match solar production.

Manufacturing & industrial

St. Croix distilleries, bottling, light industrial and port-adjacent operations where downtime stops the line.

Marinas, yacht services & large estates

Properties already running on generators that want to cut fuel deliveries by 60–80%.

Grocery, cold storage & distribution

Where every outage becomes written-off inventory.

Hospitals, clinics & government facilities

Critical loads beyond the life-safety generator, with documented battery runtime.

Shopping centers & cruise-port retail

Carport and rooftop solar with batteries for anchor tenants' critical circuits.

Scope of work

One contractor from engineering to energization

AGT is a turnkey EPC with in-house engineering, electrical, roofing, crane and logistics divisions. There is no hand-off between a designer, an installer and an electrician — and no one to point fingers at when the storm comes.

  • Rooftop, carport and ground-mount solar

    Designed to the wind loads your island actually sees, with attachment and ballast engineering, not catalog assumptions.

  • Battery energy storage (BESS)

    Sized for your critical loads: from hours of outage ride-through to full microgrid operation for days at a time.

  • Microgrid controls & generator integration

    Solar and batteries carry the base load; your existing generators become the backup to the backup and burn far less fuel.

  • Virgin Islands logistics

    Equipment ships from Florida to Charlotte Amalie and Christiansted with the schedule built around vessel sailings. Our crews work alongside licensed Virgin Islands electrical partners.

  • Roof condition & re-roof coordination

    Our sister company Advanced Roofing can assess, repair or replace the roof before the array goes on, so you never pull panels off early.

  • Interconnection, permitting & utility paperwork

    We manage the application, studies and inspections with the utility and local authorities from start to energization.

  • Operations & maintenance

    Monitoring, preventive maintenance and storm-response service plans with a 24/7 remote team.

How the work runs

From your utility bill to a commissioned system

Projects in the U.S. Virgin Islands are managed from AGT’s Fort Lauderdale headquarters, a three-hour flight from St. Thomas.

  1. Remote assessment

    Send us 12 months of utility bills, roof or site plans and your outage history. We model loads, backup needs and a first-pass system size from Fort Lauderdale before anyone gets on a plane.

  2. Site visit & engineering

    Our engineers and drone survey team visit the property, verify the roof structure, electrical service and interconnection point, and return a stamped design with a fixed scope and price.

  3. Procurement & logistics

    Hurricane-rated modules, racking, inverters and batteries are staged and containerized in South Florida, then shipped with the customs and import paperwork handled.

  4. Install, commission, monitor

    AGT crews lead the installation with vetted local trade partners, commission the system with the utility, and monitor performance and battery health from our Florida operations center.

Questions from USVI operators

Frequently asked questions

Can we still net meter with WAPA?

The original Net Energy Metering program closed to new applicants in 2017 and has been replaced by the Net Energy Billing (NEB) program, which credits exports below the retail rate. That is why we design USVI systems around self-consumption: solar covers daytime load, batteries shift the rest into the evening, and very little is exported. We handle the WAPA interconnection application and review.

How much of our bill can solar and storage offset?

For a facility with good roof or carport area, 50–80% of annual consumption is common, and higher with batteries shifting production into the evening. The estimator on this page gives a first pass; we refine it with 12 months of WAPA bills and interval data.

Is the equipment built for Category 5 storms?

AGT designs to the wind speeds required in Miami-Dade’s High-Velocity Hurricane Zone, the strictest wind code in the U.S., with engineered attachments and ballast verified for your roof. Battery and inverter enclosures are rated for salt air and installed above flood elevation, and we hand over a pre-storm shutdown and restart procedure.

Which incentives apply in the Virgin Islands?

The Virgin Islands Energy Office and federal programs change frequently, and the right answer depends on your entity’s tax position. We review the current incentives, accelerated depreciation and financing structures (cash, loan, lease or PPA) with your finance team and show the project both ways.

How long does a project take?

A remote assessment and budget takes about two weeks. From signed contract to energization, a commercial solar and battery project typically runs five to nine months depending on equipment lead times, shipping and WAPA’s interconnection process.

Who maintains the system?

AGT monitors every system we build from our Florida operations center. Scheduled maintenance and storm response are delivered by our crews and vetted Virgin Islands partners under a service agreement.
