Wind Turbine FAQ

General Turbine Information- facts/figures about the turbine:

Zephyr, Jiminy's 1.5MW wind turbine, provides approximately 33% of the electrical demands of Jiminy Peak annually. During the winter months, when the wind resource is the strongest, it may provide as much as half of our electrical demand.

Jiminy received a renewable energy grant from the Massachusetts Technology Collaborative for $582,000, which was used for all of the design and purchase of the turbine. Jiminy also receives federal tax rebates and Renewable Energy Credits to help afford the project. Payback will take approximately 7-8 years.

It takes 1 gallon of diesel fuel to generate 12 kWh and therefore this turbine permanently eliminates the need for 113,022 gallons of diesel fuel generated power.

This amount of electricity is also equivalent to:

The turbine helps to protect the long-term viability of Jiminy Peak as a resort and therefore helps to assure jobs better than being at the risk of changes in power prices.

Perhaps more importantly is the impact of this wind turbine on our generation’s grandchildren and great grandchildren in a country where we have too much dependency on fossil fuel for energy.

When the turbine is running at full capacity one would measure about 60 decibels at the bottom of the tower. Sound attenuates as one moves away from the source so at about 200 yards, the sound level would be less than 30 decibels which is equivalent to a quiet whisper.

Permitting Process

Since the Jiminy Peak wind project did not appear to meet or exceed any MEPA review thresholds the project team filed a Voluntary Environmental Notification Form.

We retained a group of knowledgeable, experienced people on environmental and wind turbine issues in order to analyze and understand every aspect of the environmental impacts this project may have.

We do not anticipate that there would be significant impact to any plant or wildlife that exists at Jiminy Peak, and do not expect the project to interact with any endangered species.

The wind project at Jiminy Peak will have little to no impact on local impacts on avian and other wildlife species. We are mitigating our potential impacts by using previously disturbed ground for the project’s location and transportation routes.

The potential impact wind power can have on avian life is often due to cutting off large areas of migratory flyways with strings of wind turbines or wind farms. A single wind turbine at Jiminy Peak should have very little impact on such a flyway. We performed a Phase 1 avian impact assessment to ensure that this project would not have an affect on local or migrating avian species.

The turbine is designed to shut down during icing conditions, and the machine will not restart until the ice has melted off the tower and blades.

Wind turbines have a 30-50 year design life. However, electrical and structural components, including the tower, foundation, and interconnection equipment have a far longer design life. Jiminy expects that at the end of the useful life of the wind turbine and blades, it will re-power the equipment using the same tower and electrical components but replacing the generator with a new and more efficient unit.

If an unforeseen circumstance arises and the wind turbine needs to be removed from Jiminy Peak, the wind turbine would be removed with a crane, the foundation would be removed to a minimum of 1ft below grade and any impacted soils would be re-vegetated.

Jiminy is proceeded cautiously with its first wind turbine. This wind turbine was designed to provide approximately 1/3 of the total electrical needs of the resort. If the first project is successful, a second machine may be considered on the eastern side of the resorts property. Jiminy has no interest in a commercial wind farm on its ridge. Any wind power at Jiminy will be used solely to reduce the electric bills of the resort and lesser the reliance on fossil fuels.
