Canberra Hospital to get 500kW solar PV system, in $3.3m govt upgrade

One Step Off The Grid

The Canberra Hospital will have a 500kW rooftop solar PV system installed on its roof, as part of a $3.3 million energy efficiency upgrade by the ACT government that will save it just under $500,000 a year on energy bills.

Outgoing ACT minister for the environment, Simon Corbell, announced the plans for the hospital on Monday, which the government would pay for using its purpose built Carbon Neutral Fund.

As well as the rooftop solar system – which will cut the hospital’s annual energy use by a whopping 721,000kWh – the upgrade will include a switch to higher efficiency lighting and other energy efficiency measures.

“The Canberra Hospital delivers a critical 24 hour service to our community and is the ACT Government’s largest user of energy, with 25% of the government’s electricity use at that site alone,” Corbell said in a statement on Monday.

“Today’s announcement will see the hospital save a massive $490,000 a year in energy bills by 2017-18 and improve the government’s overall carbon footprint.

“Each energy efficiency initiative adopted by government facilities brings us closer to our goal of zero net emissions by 2020 as a government,” Corbell said.

Other projects completed under the Carbon Neutral ACT Government Fund include lighting upgrades in ACT public schools, heating system upgrades in community facilities, including libraries and community centres, and water heaters for swimming pools at two Canberra special schools.

    If I have the figures correctly $490 k saving and cost to put in place $3300 k so a return of some 14%
    Pretty compelling figures

    Looking at these figures, 3.3 million dollars for 500KW solar array plus some other energy efficiencies. I would guess the other energy efficiencies would cost about $ 1.8 M and the solar component $1.5M Assuming some price gauging by government contractors! The solar component would generate or save 500 x 250 x 5 KWH = 0.625 MWH year at 25c approx / KWH = $156 K a year . The rest of the $ 490 K must be savings through energy efficiency. That is double the savings for energy efficiency than that from the solar array per dollar invested. A more detailed account of this example may be useful for those contemplating similar systems. Here is another thing. The off peak rate in ACT is about 10cKWH that equates to 3.34 MWH saved. Solar might attract your media attention but it seems the energy efficiencies actually save the day.

      We need some sort of accounting system for energy saved through energy efficiencies. For example LED street or other lights, solar hot water, insulation, etc. electricity not consumed is about as renewable as you can get. Especially when it is not consumed at peak times. Solar on the rooftop helps to get to the magical 90% renewables target, but the negawatts of energy avoided does not feature!
