Maximising Trustpower’s generation assets

Trustpower’s Generation Enhancement programme identifies, evaluates and implements improvements to existing generation assets, some of which are more than 100 years old.

The objective is to augment our assets to secure an estimated 60GWh a year by March 2024. The programme also targets $20 million worth of efficiency improvements through resource consents, availability and reliability initiatives.

Key to this are the high-value power scheme reviews where we undertake a ‘water to wire’ review to identify any barriers, including physical, environmental, legal, technical or financial constraints.

Trustpower’s Generation Enhancements Lead Robert Shelton says the team, established just over a year ago, identifies and evaluates opportunities to remove or mitigate the constraints.

“If there is good potential, the enhancements can be scheduled to coincide with other asset maintenance or upgrade works. This reduces the cost of scheme outages and the time required to complete the work.”

An example of this is the recently completed Kawhaka Intake upgrade to the Dillman-Duffers-Kumara power scheme in the West Coast of the South Island. This intake was upgraded during a scheme maintenance outage and it will deliver additional water to three power stations.
