UC helps power Tongan schools
University of Canterbury researchers are involved in a major collaborative project getting underway this month that aims
to introduce renewable solar power systems to all high schools in Tonga.
The project, which has been funded by the Ministry of Foreign Affairs and Trade (MFAT) through its New Zealand Aid
Programme, has three phases. The initial pilot phase will involve collaborations between Rotary New Zealand, EcoCARE
Pacific Trust, UC’s College of Engineering, Electric Power Engineering Centre (EPECentre) and Engineers without Borders,
Tonga Ministry of Education, Tonga Power Limited, Tonga Community Development Trust, and the Government and people of
Tonga.
Russell Taylor, a project manager with the School of Biological Sciences and PhD candidate in UC’s National Centre for
Research on Europe, is the CEO and Project Manager of the EcoCARE Pacific Trust that is coordinating the one-year pilot
project. EcoCARE Pacific Trust is a non-profit organisation set up by UC alumni to address health, education and
environmental issues in the Pacific region.
Mr Taylor said the pilot project would introduce 8kW on-grid solar photovoltaic (or PV) power generation systems into
five Tongan high schools on the main island of Tongatapu in order to assess the impact and feasibility in relation to an
expanded implementation of a national solar PV programme.
“This installation of renewable solar power will increase the availability and reliability of electricity for schools
which have extremely limited access to the current fossil fuel-generated electricity, which impacts on the schools'
ability to operate and students’ access to educational technologies,” he said.
“Cheap renewable energy will enable schools and communities to benefit from the immense potential that access to
energy-hungry information communication technologies can provide.
“We will also be including a significant educational component in this project that will enable schools to benefit both
financially from the power generation and scholastically from the technology that will become the focus of lessons.
Through these processes we hope to develop models that will ensure the technology is sustainable by supporting a better
understanding of the technology by the students and the community,” said Mr Taylor.
The pilot will also investigate how increased electricity production from the solar power infrastructure can impact on
the Ministry of Education's current annual power budget of TOP$750,000/year.
“On-grid systems means there is no requirement to include the cost of battery storage or replacement and as the
predicted life of the solar photo-voltaic panels is between 20-25 years, the potential financial benefits of a national
solar power programme to the Ministry of Education is between TOP$11.25 million and TOP$15million.”
Mr Taylor will head to Tonga next week with Director of Rotary NZ World Community Services, Stuart Batty and Professor
Pat Bodger (Electrical and Computer Engineering/EPECentre) to assess the five high schools chosen for the initial pilot
phase of the project and to formalise contracts and logistics.
A team from UC’s Wireless Research Centre will also travel to Tonga to assess the feasibility of installing low-cost,
high band width wireless technologies to link the five schools with audiovisual communications systems.
The pilot phase will include the installation of solar PVs and computers into five of the 11 high schools on the main
island.
“The selection of these schools is important if we are to assess the potential for these technologies to enhance
education in Tonga and other Pacific Island nations, and to refine models that can be rolled out into the wider Pacific
communities,” Mr Taylor said.
The ultimate goal of the phased project is national installation of the solar PV systems throughout all of the high
schools in Tonga – which is about 36 schools on 21 different islands.
Mr Taylor said following what he hoped would be a successful pilot phase, the plan for the national roll-out of the PV
systems to high schools was for installation to be coordinated by teams including UC postgraduate engineering students
as part of the Master of Engineering Management course, NZ registered electrical inspectors, staff from Tonga Power and
the Ministry of Education in Tonga, school students and members of the local communities.
He stressed that the PV system and computer installation was just one part of a wider “package” of related projects in
the pipeline that would deliver significant benefits to the Pacific Island community. There are discussions underway
about how other UC groups including Audio Visual Services, student group AIESEC, anthropologists, marketers,
geographers, sociologists and health sciences academics can “get on board” with allied research programmes.
