The Waitaki hydroelectric scheme is a series of hydroelectric power stations located in the Waitaki River basin on the South Island of New Zealand. It harnesses the river's flow to generate electricity, contributing significantly to the country's renewable energy supply. The scheme includes several dams and power stations, with the largest being the Waitaki Dam. Constructed in the mid-20th century, the scheme plays a crucial role in New Zealand's energy infrastructure. It helps to provide a stable and reliable source of electricity while minimizing environmental impact, as it utilizes the natural flow of the river without depleting water resources.
