Case Study

Data Visualisation unlocks 360° views of Process Safety Performance

Helping Contact Energy gain visibility of process safety performance and quickly understand trends, outliers, and patterns in their process safety data by harnessing the power of data visualisation.


Contact Energy is one of New Zealand's leading providers of electricity, natural gas, broadband, solar & renewable energy. They own and operate twelve power stations in New Zealand with a generation portfolio made up of geothermal, hydro and natural gas assets.

The Challenge

Contact Energy wanted a 360° view of their process safety performance across sites and plants that could be used by executives and operational staff. It needed to meaningfully visualise 60+ KPIs across 6 different risk control areas and would draw from 7 different data sources.

The Solution

Throughout the project, Harmonic worked closely with health and safety experts and executive stakeholders, to plan, design, and develop the dashboard in R.

The highly visual tool supports executives and operational staff with an overview of KPIs, enabling immediate identification of areas that need their attention. Added functionalities allow executives to monitor performance improvement trends, while engineering subject matter experts can quickly investigate and respond to areas of concern by drilling down into data when required.

Specific use case needs are supported through custom view functionality which in return improves staff efficiency. The solution is also dynamic to allow adjustment and addition of KPIs and data is automatically updated daily.

The Result

  • Custom view functionality enables users with specific information needs to efficiently get the information they require.
  • Encouraged behavioural change through increased awareness of process safety performance at all levels of the organisation.
  • Meaningful visual communication of analytics via the dashboard enables quick and effective application of insights as well as tracking performance improvement trends.
  • Gained confidence that health and safety performance is visible and is being appropriately addressed.
  • The dashboard was so successful that Contact has already sold the concept internationally to an Australian generator.

“Contact engaged Harmonic in 2017 to build a near real-time dashboard of key performance information. From their initial prompt high-quality concept, through design, build, commission and operation of the dashboard we have found Harmonic’s focus on responsiveness and quality of output to be of the highest order."
