Quick Win project No. 10: Parke Holme Community Child Care, SA
Past projects have been either solar-only or a mix of solar PV and energy efficiency (EE) measures. This is our first EE-only project, replacing all the Parke Holme CCC fluoro tubes and halogen downlights with energy efficient LED lighting. Energy efficiency is an equally important part of the transition to 100% renewable energy as solar PV, and in some cases is an even more cost effective way of reducing carbon emissions.
Note: The payback time on a LED lighting upgrade depends greatly on the number of hours lighting is used. Parke Holme CCC lighting is in use during all opening hours, from 6.45am to 6.30pm Monday to Friday, so their lighting upgrade will pay for itself in around 2 years.
Due to recent changes in SA Power Networks regulations affecting new solar installations, it is likely any future Quick Win projects in SA will also be EE-only projects, but we’ll continue to fund solar-only and solar+EE projects in other parts of Australia.

Note: The ‘At subsequent projects’ figures should be a bit higher than shown below. This is because we temporarily used some Big Win funds to help fund some of our early Quick Win projects, and when we later repaid that amount to the Big Win fund we used two loan repayments from Parke Holme ($800) to help pay that back. That money is now achieving reductions in carbon emissions via the Big Win landlord-tenant solar scheme, but that benefit is not reflected in the table shown below.
|Project 10||kW (solar &/or
|MWh to date
avoided to date
|At Parkeholme Community Child Care||2.08 kW||13.20 MWh||13.20 t||$3,760|
|At subsequent projects||1.96 kW||2.48 MWh||2.48 t||$3,086|
|Total||4.04 kW||15.68 MWh||15.68 t||$6,846|
Install date: 19/01/16.
Number of days in operation: 822.
* Since the amount of CO2 avoided is highly dependent on the fuel source used for local grid electricity, and since each CORENA project is in a different location, we have used 1MWh = 1 tonne as a rough approximation across all projects.

Loan repayments received so far:
|Work details||Cost||Expected savings|
|- Replace 61x 36W fluorescent lamps with 18W LED lamps|
Note: A 36W fluoro plus ballast uses around 46W.
- Replace 8x 50W halogen downlights with 9W LED fittings
Note: A 50W halogen downlight actually uses around 55W.
