Introduction to the NZGB
Welcome to the New Zealand Generation Balance website. The purpose of the NZGB is to help predict, isolate and prevent situations where available generation is insufficient to meet projected load.
This website has been established to:
- Communicate to industry participants potential North Island generation balance shortfalls over the next 200 days.
- Provide industry participants with a means of assessing the potential impact of their planned outages on the North Island generation balance.
- To enable industry participants to select optimum outage periods which least impact on the North Island generation balance.
The NZGB provides significant graphical analysis of outages and load profiles, as well as various user-focused features to help analysts rapidly locate information and trends of interest.
Powerful trend charts
The dashboard provides an immediate graphical breakdown of projected risk, generation and load out to 200 days

Precision and Integration
Easy-to-read charts and in-depth tabular data co-exist throughout the site, giving the analyst the precise level of detail they need at a glance
From overview to detail
In-detail day analysis allows problems to be quickly identified and projections assessed
Generator, Region and Asset Owner displays let the analyst move quickly through the data to identify hotspots and trends
Personalised experience

NZGB Monthly reports
The New Zealand Generation Balance (NZGB) is calculated using estimated load and outages of generation and transmission equipment notified through POCP. The NZGB web application automatically calculates the generation balance on a daily basis and Transpower’s System Operations Division produces a monthly report that provides additional analysis and commentary.
