Green light tested in city park


Palmer­ston North’s first street light pow­ered by the wind and sun has been in­stalled at Hokowhitu Do­main near the car park and play­ground.

The im­ported Eol­green unit, worth $25,000 in­stalled, has been pro­vided as a demon­stra­tion unit in a col­lab­o­ra­tion with dis­trib­u­tors Hi­way Group for the cost to the city coun­cil of its con­crete foun­da­tion.

The light unit, with pho­to­voltaic pan­els fac­ing north and a tur­bine on top, is some­thing of ‘‘a part­ing gift’’ from re­tir­ing city coun­cil­lor Chris Teo-Sher­rell.

The port­fo­lio holder for en­vi­ron­ment and sus­tain­abil­ity said it had taken about a year to bring the project to fruition af­ter he heard about the Span­ishde­signed street light­ing units.

The con­cept ap­pealed not just be­cause it was clean and green, but also be­cause it had po­ten­tial to save money.

The man­u­fac­tur­ers’ web­site said the sys­tem could pro­vide 20 per cent sav­ings over con­ven­tional street light­ing sys­tems.

Teo-Sher­rell said the tech­nol­ogy had po­ten­tial to be used in pub­lic parks, on walk­ways, and pos­si­bly in new sub­di­vi­sions to avoid the cost or prac­ti­cal dif­fi­cul­ties of lay­ing power ca­bles.

The units were able to gen­er­ate and store about four days of en­ergy to sup­port them through times of low wind and sun­shine hours, or could be linked to ex­tra lights.
