The ACTs 100% renewable energy target and Australias
The ACTs 100% renewable energy target and Australias changing generation mix Jon Sibley Director, Energy and Waste Policy Environment and Planning Directorate ACT Government Australian Capital Territory Canberra: Australias Capital Population: 400,000 Advanced knowledge economy
Ranked #1 in the world in the world for climate change targets o 40% reduction from 1990 level by 2020 o Carbon neutrality by 2050 o 100% renewable energy by 2020 SECTION 1: National policy context The National Electricity Market (NEM)
National market established 1998 40,000 km of transmission, 9 million customers Five interconnected states/price regions
50,000GW, dominated by coal and gas: QUEENSLAND Fuel sources (2013-14) SOUTH AUSTRALIA NEW SOUTH WALES VICTORA
TASMANIA Market structure LGC market Electricity demand forecast National renewable energy target $ Embedded
generators Contract market Retail Generation Spot market Customer Distribution
Transmission Victorian spot market prices (Example: 17 July 23 July 2016) Survey result: Bankability of future revenues Not bankable Bankable Significant policy and
pricing uncertainty in Australia Lack of long term off-take deals Asset life Merchant risk greatly increases the costs of finance National 2020 target unlikely to be met
Survey result: Importance of factors in investing in developing Asian economies Other factors: Cultural and social understanding. Land law and ease of planning regulations. Clear ability to connect to grid. Absence of corruption. Possibility for the foreign investor to be a majority owner of the assets. SECTION 2: ACT renewable energy policies Large-scale Renewable Energy Auctions Reverse Auctions based on value for money
Open to projects across the National Electricity Market (NEM) Costs recovered from all ACT electricity users via local network operator 20-year fixed feed-in tariff rate Contract for difference approach Contract for difference payments Example: FiT payments in Victoria (1/7/2016) Payments by generators

South Australias changing generation mix Imports from Victoria Interconnector Exports to Victoria Source: http://reneweconomy.com.au/2016/wind-and-solar-become-new-base-load-power-for-south-australia-99364 Up to $220M in network savings! Next Gen Battery Auctions
Pilot currently underway 150+ homes, $600k subsidy Tesla, Panasonic, LG Chem Next gen auctions to 2020 5000+ homes, 36MW $25M subsidy Winners TBA Conclusion 1. Australia has extensive experience in integrating
renewables into advanced market systems 2. The ACTs reverse auction feed-in tariff program has delivered investor certainty, driving down prices 3. We can prove potential for a 100% renewable grid by supporting renewable energy along with complementary technologies
