09/05/09 - The Town Council, in conjunction with the Planning Board, will convene a public workshop Thursday, September 10 at Town Hall to discuss an addition to the town’s zoning ordinance that would allow for a public utility zone at the town’s Transfer Station.

A public hearing on the change is set for October 5.

The town is exploring the feasibility of installing a 660-kw wind turbine at the transfer station — either by itself or in conjunction with a private concern.

The proposed turbine, standing 265 feet tall with its blade fully extended, would cost approximately $2.5 million. However, proponents say it would pay for itself, even if owned outright by the town, in five to seven years.

The noise level of such a turbine is rated not to exceed 45 decibels at 300 feet. By way of comparison, quiet conversation in a library is about 30 decibels, and normal conversation is about 70 decibels.

Electricity generated by the turbine could significantly reduce — if not entirely eliminate — the $450,000 annual bill for electricity to town-owned buildings. And, excess energy could be sold back to National Grid if a cable is eventually installed to the mainland.

Father Joseph Byron of Portsmouth Abbey will be on hand to explain how the abbey acquired its turbine, and the advantages derived from it.

First Warden Kim Gaffett, Town Councilor Peter Baute, and Town Planner Jane Weidman and Planning Board members will be present to answer questions.

Gaffett says that the zoning change is a first step that must be taken before a feasibility study can be commissioned for the site.

The Transfer Station land was left to the town by Jack Gray for use as a “landfill.” There is some question, Gaffett said, if the terms of Gray’s will would allow for a turbine installation. However, the zoning language must be changed before that conversation can start, she said.
