Can a windy island still be a poor match for a seasonal accommodation business?

The short answer

Yes. Strong wind outside the visitor season can have limited value if occupancy, site demand and allowed export are low at that time. Assess the months when electricity is needed and the destination for surplus generation during closure. A wind-rich location is only one part of the decision. The business also needs an appropriate connection, continuity plan, service access and a project cost justified by energy it can actually use or sell.

Separate occupied and closed periods

Identify refrigeration, water services, security and other loads that remain during closure. Use actual occupancy records where available instead of assuming a uniform annual load. Seasonal staffing and boat access may also affect service response. The comparison should include normal operation, closure and reopening, because each can have different electrical requirements and access constraints.

An annual-total trap

For illustration, an accommodation business uses 60 kWh/day for 120 occupied days and 5 kWh/day for the remaining 245 days. Annual demand is 8,425 kWh. Suppose a hypothetical wind study allocates 3,000 kWh to the occupied period and 7,000 kWh to closure. Without storage or export, at most 4,225 kWh could match those period totals, even before checking hourly coincidence. The annual 10,000 kWh estimate therefore overstates immediately usable energy.

Do not assume seasonal storage

Storage intended to bridge short generation gaps is not automatically economical or technically suited to carrying large energy volumes between seasons. Treat any proposed seasonal storage as a separate project with explicit losses, usable capacity and operating requirements. Likewise, exported electricity only has value under the actual approved connection and commercial arrangement.

Compare the business case on accepted energy

Evaluate wind, solar, existing supply and a hybrid arrangement against the same occupancy calendar and continuity requirement. Include island logistics, local installation and maintenance access. Wind may still have a worthwhile role for year-round loads or an allowed export arrangement. Where useful energy is too limited, a smaller project or a lower priority for wind is a valid outcome.
