9 December 2015, Energy Post, German grid operator can handle 70% wind, solar before storage needed. The company responsible for more than one-third of Germany’s electricity grid says there is no issue absorbing high levels of variable renewable energy such as wind and solar, and grids could absorb up to 70 per cent penetration without the need for storage, writes Giles Parkinson of Reneweconomy.com. Boris Schucht, the CEO of 50 Hertz, which operates the main transmission lines in the north and east of Germany – and which is 40 per cent owned by Australia’s Industry Funds Management – says the industry’s views of renewable energy integration has evolved rapidly in the past decade. “It’s about the mind-set,” Schucht said at the Re-energising the Future conference in Paris, and later to RenewEconomy. “10 to 15 years ago when I was young engineer, nobody believed that integrating more than 5 per cent variable renewable energy in an industrial state such as Germany was possible.” Yet, Schucht says, in the region he is operating in, 42 per cent of the power supply (in output, not capacity), came from wind and solar – about the same as South Australia. This year it will be 46 per cent, and next year it will be more than 50 per cent. “No other region in the world has a similar amount of volatile renewable energy ….. yet we have not had a customer outage. Not for 35 or 40 years.” Read More here

9 November 2015, One Step off the Grid, Community renewables development guide launched by Victorian govt. Victoria’s community renewable energy sector got a boost this week with the state government’s release of a guide to developing community owned-projects, as part of its upcoming Renewable Energy Action Plan. State energy minister Lily D’Ambrosio launched the Guide to Community-Owned Renewable Energy for Victorians at the annual general meeting of Australia’s first community-owned wind farm, Hepburn Wind, in Daylesford. According to a media release, it will help local groups make informed decisions about establishing community renewable projects, including wind, solar, small-scale hydro, geothermal, bioenergy (from waste products) and energy storage technologies. The guide also covers the development of sound business proposals, sources of possible funding (including crowdsourcing, grants and financing options), selecting the most suitable technologies, managing the project, stakeholder consultation and connecting to the grid.

7 October 2015, Renew Economy, Hunt says “inevitable” large numbers will quit grid with battery storage. Australian environment minister Greg Hunt says it is inevitable that significant numbers of consumers will leave the grid in coming years, and repeated his vow to help accelerate the deployment of battery storage. Hunt was asked on ABC TV’s Lateline program on Tuesday – following a segment on a couple in the Blue Mountains going off-grid – if he thought that significant numbers of consumers would follow. “I do. I think it is inevitable,” Hunt said, before noting that Australia already had the highest penetration of rooftop solar in the world – an average 15 per cent across the nation. “Increasingly we will see the adoption of battery storage, which is the key thing to enable people to go off the grid. This is clearly the future,” Hunt said. “The debate is how long it takes and the task for government is to help bring that forward.” Indeed, two big international battery storage developers have chosen Australia to be their global launch pad for their battery storage initiatives. This includes Tesla and California counterpart Enphase Energy, which describes the Australian market as the most promising in the world. Not everyone, however, agrees that consumers should be encouraged to go off-grid, and Hunt’s comments could be seen as controversial if that is what he is urging. Read More here
30 July 2015, The Conversation, Fact Check: Would Labor’s renewable energy plan cost consumers $60 billion? (It) will mean a massive bill, perhaps A$60 billion or more, that will have to be carried by the consumers of Australia. – Prime Minister Tony Abbott, speaking to reporters about Labor’s plan to source half the nation’s power from renewable energy sources by 2030, July 27, 2015. Abbott’s quote, a response to the new Labor policy to set a goal of 50% renewable energy by 2030, appears to be drawing on reported comments by Paul Hyslop, chief executive of ACIL Allen – the company used by the government’s Warburton review into the existing Renewable Energy Target (RET). The prime minister’s office sourced the A$60 billion figure to an article in The Australian last week that quoted Hyslop saying of Labor’s 50% renewables pledge that: If this were met by wind power it would require 10,000 to 11,000 additional turbines… with capital costs for the turbines alone of $65 billion. Hyslop’s ACIL Allen colleague, Owen Kelp, told Sky News this week that the A$60 billion was a “fairly simplistic, back-of-the-envelope calculation”. When asked by The Conversation for a copy of any calculations to see how the A$65 billion capital costs figure was reached, Hyslop said the internal analysis was not publicly available, but explained that: To get to the 50%, you need about another 80,000 gigawatt-hours… To build that with renewables, the current cheapest technology would be wind. We estimate between 10,000 and 11,000 additional wind turbines with a bottom end estimate of around $65 billion in capital costs… Would it have an impact on consumers? It really depends on the trade-off on the cost of funding the subsidy versus the downward pressure on electricity prices. We don’t know exactly what that would look like. That would be a significant piece of modelling. Read More here
