(2010) African Game Lodge Off-Grid Installation
NATURE POWERED BY NATURE
African Game Lodge, having no grid-support made use of SSS (Specialized Solar Systems) off-grid energy consultants to advise on energy efficiency and some practical sustainable solutions for this large animal release rehabilitation center that required off-grid electrification for their main lodge, kitchens, guests cottages, restaurant, reception area, etc.
SSS installed and upgraded all the energy systems for the entire complex and currently, these systems have proven to be hassle-free and completely self-sufficient.
BACKGROUND OF THE LODGE AND CONSERVATION WORK:
Steve Irwin, great conservationist once said that the lack of wilderness would be the biggest challenge to conservation. “If you do anything, buy up land”, he said over and over when interviewed. And this has come to pass. Wilderness gives way to urbanization, plains transformed into pastures and intensive crops. One of the biggest factors contributing to the decline of many species throughout the world is a loss of habitat. Amongst this backdrop, Tenikwa Rehabilitation Centre accepts injured and displaced wild animals for rehabilitation, treating them and when ready, returning them to nature where they belong. Or sadly, once belonged. Increasingly, finding safe havens to return the animals is becoming harder to find. Hotspots where intense farming, agriculture, and urban fringes cast wild animals out and claim their heritage. It’s simply futile to return them to these areas of conflict.
Enter African Game Lodge, Tenikwa’s latest conservation project. A 4300-hectare private reserve set amongst the spectacular mountainous karoo scenery and home to the dwindling remaining 9% of the renoster veld. Through their philosophy of Rehabilitation, Awareness and Biodiversity preservation, African Game Lodge completes the conservation sphere.
African Game Lodge will be utilized as a pre-release preparation site, a release site for appropriate species and most importantly an important part of a vast wilderness area, set aside for conservation where guests can enjoy the rugged beauty of the area but also witness a conservation project in action.
