Perth’s Corpus Christi College students are learning by the power of the sun, with the College now able to meet almost one third of its power needs from energy generated on-site from rooftop solar, under a Power Purchase Agreement (PPA) with solar provider Enigin.

It’s an energy and cost saving initiative that could be utilised by many more schools Australia-wide.
WA energy services company Enigin, financed the $300,000 upfront cost of installation at the College through an Energy Efficient Loan - a joint initiative of the Commonwealth Bank and Clean Energy Finance Corporation (CEFC).

CEFC CEO Oliver Yates, said there is strong potential for solar energy to become an important way for Australia’s 9,400 schools to better manage rising energy costs.

“This is a practical demonstration of the positive change possible through greater adoption of renewable energy. The College can make a big difference to its power bills, while delivering a meaningful cut to its carbon emissions,” Mr Yates said.

“Schools have the biggest energy demands when the sun is shining, which is exactly when they can be switching to solar energy. For many schools, money saved on energy bills is money that can be spent in the class room.

“Installing solar is a very practical way of demonstrating to students and broader school communities the benefits of renewables for improved sustainability.

“We’re pleased that the Energy Efficient Loan can help accelerate the solar plans of schools, businesses and not-for-profit organisations, by financing the upfront cost of installation.”

Corpus Christi College is a 32-year-old Catholic co-educational college in the southern Perth suburb of Bateman. Based on forecast electricity prices, the school is expecting to save more than $1.5 million on its energy bills over the 25-year life of its new solar PV system.

Corpus Christi College will be able to use solar power for 30 per cent of its current electricity needs. Energy services and solutions operator Enigin, has installed more than 670 panels on the school’s rooftops to generate supply. The system has been designed to not export excess electricity, to comply with network grid connect approvals.

Corpus Christi College Principal Mrs Caroline Payne, said installing solar on the school’s rooftops would provide ongoing savings and reduces the College’s exposure to increasing electricity prices.

“Another important factor for us goes beyond dollar terms. We are building on our strong reputation for encouraging independent and creative thinkers who have a sense of purpose.

We want our students to understand their responsibilities as stewards of the earth and tapping into solar is a practical way for us to lead by example,” Mrs Payne said.



Enigin WA: Case Study – Perth Convention and Exhibition Centre Car Park


WALGA preferred supplier Enigin WA recently completed an EPCM energy efficient lighting retrofit project for City of Perth Parking at the Perth Convention and Exhibition Centre undercover car park.

The clients brief was to achieve a 60% reduction in power consumption while maintaining an average 60 lux average maintained luminance. The lights were required to have a minimum rated lamp life of 80,000 hours which would significantly reduce maintenance costs.

The project scope included the lighting design and installation and commission of 537 induction lights in the underground car park with the inclusion of a further 39 induction lights and sensors retrofitted to the existing external car park light poles.

Each new induction light is linked to strategically placed motion sensors which activate the light from its 50% dimmed state to 100% brightness which significantly reduces wasted energy when no movement is detected. Dimming the lights when full brightness is not required saves energy and reduces operational costs. The external lights are timer controlled which shuts them off during daylight hours.

The project has increased light (lux) levels to comply with Australian Standards, improving amenity while reducing energy costs and CO2e emissions by over 60%. The financial savings to the city will continue to grow as the operating life of the induction lights is eight times longer than the legacy lights they replaced.
