Project OverviewProject Overview
The Native Village of Venetie Tribal Government, is the governing body of the 1.8 million acre Venetie Indian Reserve,our tribal homeland, part of the Gwich’in Nation.
Our culture, tradition, and subsistence depend upon the Porcupine Caribou Herd.

Our remote communities are dependent on diesel fuel for most of our energy needs.
We want to reduce our dependency, and increase our self-sufficiency.

Electricity needs Solar energy output
During the summer...
we use much lesselectricity
and we have sunlight 24/7.

Project Overview (cont.)Project Overview (cont.)
We believe solar electricity, together with better energy efficiency, can:
- teach our young people new skills
- maintain our subsistence ways
- save fuel and money in our villages
- lessen environmental risks of fuel use

In fall 2002, we upgraded our fixed-array PV system components after a manufacturer’s recall.
We integrated the upgraded components with our performance monitoring system.
Upgrades helped to solve earlier power system integration problems.

In summer 2003, we enabled internet viewing of our PV system performance in near-realtime.http://www.rusg.com/educational/nrthrnsol/stations/stations.shtml
We hope to develop a local school curriculum around it.

Project Background (cont.)Project Background (cont.)Our fixed-array PV systems have been working well since our upgrades, but our tracker really delivers.
In summer 2004, we will install an identical 2.2 kW tracking-array in Arctic Village.
