ABSTRACT
One of the largest zoos in the world, the Toronto Zoo houses over 5,000 animals and has plant collections representing six zoogeographic regions. Protecting these collections, many from tropical and sub-tropical locations, and maintaining the aquaria, the commissary, the animal hospital and public services such as washrooms is critical during power outages.
A new emergency back-up power system with an uninterruptible source of fuel was required. The system had to operate with minimal environmental impact. A dual source of fuel offered the best solution.
