Safety at Generation Sites

Most hydroelectric dams and stations are remotely controlled by operators stationed many kilometres away. Here is some advice on staying safe when near our dams and their associated waterways.

Our Compliance

Power, gas and telecommunication networks all carry inherent risks. Everyone should be alert to potential risk around waterways, on large structures and during events such as storms and floods. Without due attention and care, there will always be risk. 

We have a comprehensive Public Safety Management Plan. This aims to minimise risk of injury to the general public and risk of damage to property, that may result from our assets and operations. The plan complies with the NZS7901:2008 Safety Management System for Public Safety. It spans the asset lifecycle, including construction, maintenance and operation. 

Trustpower’s safety planning also involves full compliance with the following New Zealand Safety Regulations: 

Electricity (Safety) Regulations 2010

Gas (Safety and Measurement) Regulations 2010

Building (Dam Safety) Regulations 2008
