1 Renewable Energy in Victoria report 2012

2 Executive summary The Renewable Energy in Victoria 2012 report provides an overview of Victoria s electricity generation from renewable energy sources in the 2012 calendar year. The report presents a detailed breakdown of renewable energy sources along with a comparison of generation to Victorian electricity consumption. Changes in annual capacity and generation output are noted with respect to the key technologies of bioenergy, hydro, wind and solar photovoltaic (PV). The report covers electricity generation from renewable sources including wind, hydro, solar and bioenergy. It does not cover renewable energy used for thermal applications such as solar hot water, solar cooling, industrial solar heat, geothermal direct use and heat from bioenergy sources.

5 The Clean Energy Council is the peak body for Australia s clean energy industry, working with more than 600 solar, wind, energy efficiency, energy storage, bioenergy, hydro, cogeneration, geothermal and marine energy businesses. The Clean Energy Council aims to accelerate the transformation of Australia s energy system into one that is smarter, cleaner and more consumer-focused. Background The Clean Energy Council tracks the installation of renewable energy generators and the amount of electricity generated from renewable energy sources all over Australia. For the Renewable Energy in Victoria 2012 report, generation data has been sourced from the Australian Energy Market Operator (AEMO) and operating generators. The consumption data is sourced from AEMO s halfhourly demand intervals for the calendar year 2012, available online AEMO aggregated price and demand data files.

6 Renewable energy generation installed CApacity Since 2000, Victoria s installed capacity of renewable energy has almost tripled, increasing from 668 megawatts to more than 1860 megawatts in This puts Victoria s total installed renewable energy capacity third nationally after New South Wales and Tasmania, which both have huge amounts of hydro capacity installed capacity of renewable energy in Victoria, in megawatts 3825 Victoria s total renewable energy generation in 2013, in gigawatt-hours Capacity of renewable generation technologies by year 2 Installed Capacity (MW) Fuel type Bioenergy Hydro Solar Wind Total The renewable energy mix Victoria s total renewable energy generation for 2012 was 3825 gigawatt-hours, which was an increase of 874 gigawatt-hours, or nearly 30 per cent more than the amount of generation in This was largely driven by an increase in the amount of wind energy generation in 2012, and also a significant increase in the amount of solar energy produced. The total electricity generation by each technology is presented above. 2. throughout the report, the nominal dates for installed capacity refer to end of that year (i.e. 31 December). Generation output is calculated over the calendar year specified. 04 Note: installed hydro capacity in this report does not include the 550 megawatt Snowy Hydro Murray 2 project, which is physically located in New South Wales. Since 1 July 2008 the power station has been allocated to the Victoria region of the National Electricity Market so in some other sources may be listed as Victorian.

7 Victorian renewable energy generation output by calendar year Output (GWh) 2012 Fuel type Bioenergy Hydro Solar Wind Total Year Solar Biomass Hydro 2000 Wind Output (GWh) The wind sector has expanded significantly since 2000, growing from less than 0.1 megawatts to an installed capacity of 519 megawatts in In 2012, wind energy also made up more than 27 per cent of Victoria s renewable electricity generation capacity. Output from Victorian wind farms has increased from just 260 megawatt-hours in 2000, to 1674 gigawatthours in Solar power has also experienced rapid growth, driven largely by household solar systems. Output has grown from 18 gigawatt-hours in 2009 to 550 gigawatt-hours in 2012, a 30-fold increase. Bioenergy has also grown steadily, now contributing 17 per cent of Victoria s renewable energy. Finally, hydro has maintained an installed capacity of just over 800 megawatts, and in 2012 generated 950 gigawatt-hours of electricity. Annual output from Victoria s hydro power plants varies with rainfall, with the peak of the past 10 years reached in 2002 with 1100 gigawatt-hours in 2002, compared to the 10-year low of 404 gigawatthours in

8 Renewable energy percentage victoria In 2012, renewable energy generation produced from Victoria met around 7.7 per cent of the state s total electricity demand. Victoria s renewable electricity percentage 7.7 % victoria % national AVERAGE Renewable energy generation as a percentage of total energy demand This is lower than the national percentage of renewable energy, which is per cent. The national figure is boosted by states like Tasmania and New South Wales, which have significant hydro resources, and South Australia, which gets approximately 25 per cent of its energy needs from wind power. In this report, the renewable energy percentage is calculated as the ratio of total renewable generation located in Victoria to AEMO s half-hourly demand figures for Although there would be small losses in the transmission networks, they are difficult to determine though could be expected to be around 3 per cent. Rooftop solar photovoltaic (PV) generation would not experience this network loss because the generation is physically close to where the electricity is used. Victoria may also import renewable generation from neighbouring states to meet its demand. This could mean that Victoria actually uses a higher proportion of renewable energy than reported. 06

12 Hydro power In 2012, Victorian hydro generators supplied 950 gigawatthours of renewable energy from 803 megawatts of installed hydro plant. This was a significantly higher contribution than the 813 gigawatt-hours generated in GWh of renewable energy supplied in plants operating Hydro generation data is sourced from all generators located within the Victorian border, with the exception of the Hume Dam hydro power plant, which is considered 50 per cent within Victoria. Generation data was sourced where possible from AEMO, and where the plant is not a scheduled generator, by direct communication with the owner. Using these criteria, Victoria has 32 operating hydro plants. The graph below shows both the output and capacity for the period 1990 to 2012, and clearly demonstrates a large variation in hydro output from year to year. Aside from an increase of 140 megawatts of new capacity in 2009, with the Bogong power station being commissioned in October 2009, the majority of capacity changes over the period were from a number of small pipeline mini-hydro plants installed by Melbourne Water. The large dip in output from 2007 to 2009 is attributable to low reservoir levels. The effect of widespread rain throughout the state in from late 2010 is quite pronounced in the output data, even though the majority of rain only fell in the final three months of that year.

13 Bioenergy In 2012 bioenergy sources supplied 651 gigawatt-hours, up from 633 gigawatt-hours in This was about 17 per cent of Victoria s total renewable energy generation. 651 GWh of renewable energy supplied in 2012 Total installed capacity of bioenergy at the end of 2012 was 129 megawatts. The chart below shows the capacity of Victoria s 28 bioenergy generators from 1990 to 2012, broken down by fuel type. A single black liquor plant with a capacity of 54.5 megawatts dominates with 42 per cent of installed capacity. Victoria also has a lot of landfill methane capacity, contributing a further 38 per cent of capacity. Since 2006 Victoria has seen the addition of about 13 megawatts of sewage methane as well as about 10 megawatts of landfill gas generation. The data indicates a higher capacity factor for landfill methane than the other fuel types. In 2012, the capacity factor for landfill sites was over 73 per cent compared to the bioenergy sector average of 58 per cent. 28 plants operating Capacity of bioenergy generators by fuel and by year Output (GWh) Digester gas Other Sewage methane Landfill methane Black liquor Year 11

14 Solar Solar energy supplied 550 gigawatt-hours (14 per cent of all renewable electricity) to Victoria in 2012, up from 225 gigawatt-hours in GWh of renewable energy supplied in megawatts installed capacity of solar PV in Victoria This was due to the massive growth of rooftop solar PV systems driven by falling solar prices, as well as state and federal government incentives. The table below shows an estimate of installed solar PV capacity in Victoria, according to the Clean Energy Regulator s data on Small-scale Technology Certificate (STC) creation. This data does not cover all systems, as certificates may be created up to 12 months after installation of a generator and are not necessarily created for all systems. Installed capacity in 2012 went from 270 megawatts to 418 megawatts. Solar panel generation for Victoria is calculated using a capacity factor of 15 per cent. Of the 418 megawatts of installed solar PV, household solar contributed 417 megawatts and commercial projects made up slightly more than 1 megawatt. Commercial projects sized between 180 kilowatts and 300 kilowatts generated a total of 1846 megawatt-hours for With the price of solar panels dropping, 2013 may see further uptake of commercial-size projects. Installed solar PV capacity (Clean Energy Regulator data) Installed capacity (MW) Year As discussed in body of text, the most recent 12 months data at time of publication is subject to review based on future STC creation.

16 Wind Wind energy has been the largest contributor to Victoria s renewable electricity supply for the last four years. In 2012 Victorian wind energy provided 1674 gigawatt-hours, up from 1280 gigawatt-hours in GWh of renewable energy supplied in commercial plants operating At the end of 2012 Victoria had 11 commercial wind farms over 1 MW in capacity, mostly located in the west of the state. In 2012 they generated enough energy to power over 230,000 average Australian homes. Two new wind farms were completed in 2012, adding almost 87 megawatts of new generation. Those two projects were Morton s Lane, roughly 38 kilometres east of Hamilton, and Oaklands Hill, which is 3 kilometres south of Glenthompson. The 2012 generation figure includes some generation from the Macarthur wind farm, which was progressively commissioned throughout late 2012 and finally opened in April As a result, the installed capacity figure for Victoria does not include Macarthur but the generation does include some of the wind farm s output. Macarthur is Australia s largest wind farm and also the Southern Hemisphere s largest wind farm at 420 megawatts. Electricity output data for the major wind farms is sourced directly from AEMO, which collates half-hourly market interval data for the operation of the National Electricity Market. Data for the smaller wind farms was sourced directly from the generators. The performance of wind farms is represented in terms of the capacity factor which is the ratio of energy output to total possible energy output if the wind farm was operating at maximum capacity at all times. The aggregated capacity factor of Victorian wind farms in 2012 (comparing total generation to total installed capacity) was 34 per cent.
