22 November 2016, One Step off the Grid, Victoria town (Newstead) calls for partners for 100% renewable energy plan. he Victorian town of Newstead is seeking proposals from potential project partners who could help refine its plan to reach 100 per cent renewable energy within 5 years, and which could act as a blue-print for other towns in the state to follow. Newstead, a town of around 500 people, is considered a flagship project project for the state, and is looking to build up its renewable energy capacity and then integrate these into the local grid with battery storage and new “energy market” ideas. Tosh Szatow, director for Energy for the People, which is advising the township, says the call for expressions of interest is designed to flush out ideas from solar companies, retailers, trading platforms and others that could be adapted to the town’s plans. “We have sketched out a plan, and know what a model could look like,” Szatow says. “Now we want to test some of this thinking and identify some of the partners that could help in the project.” The Newstead plan is seen as a fore-runner for other towns and cities in the state, and elsewhere in Australia. And far from being a rogue proposal, the idea has the support of the state Labor government and even the local network operator, Powercor, which is co-operating on data, network capacity and tariff design.

19 November 2016, One Step off the Grid, Enova reaches major milestone, looks to expand and try peer to peer trading. Australia’s first community-based electricity retailer, Enova Energy, has reached major milestone of 1,000 customers, and is already looking to expand its geographic base and push into new areas such as peer to peer trading. Enova, based in Byron Bay in the northern rivers region of New South Wales, says it has reached its 1,000 customer level several months ahead of target, as it seeks to reach its break-even goal of 4,000 customers within the first two years of operation. CEO Steve Harris says the retailer has also attracted a higher number of business customers – 70 so far – which will help revenues, and possibly offset a small impact on margins from rising wholesale prices and high prices for large scale renewable energy certificates. Harris says there is clearly a groundswell of community interest in alternatives to the big oligopolies, and a fair deal on renewable energy. Nova, which describes itself as a “community owned renewable energy company”, pays 10c/kWh for solar feed in tariffs, more than 50 per cent above most retailers. “The higher feed in tariff is paying dividends for us. But it’s about community and it’s about environment. Households and businesses are showing they are quite happy to switch from their existing provider,” Harris told One Step Off The Grid in an interview. Harris says Enova is also benefiting from partnerships, such as a solar bulk buy program on the south coast of NSW, and another solar initiative in the ACT. Read More here
2 November 2016, Renew Economy, Malcolm Turnbull blown off course by South Australia’s 100% renewable energy. It is something of an irony that prime minister Malcolm Turnbull’s attempts to visit the South Australian city of Port Lincoln over the weekend should have been thwarted by strong winds – winds, it should be noted, that provided 100 per cent of the state’s power needs for much of the day. According to local media reports, Turnbull’s planned visit to Port Lincoln on Sunday was aborted when his plane was unable to land after two attempts due to strong winds. It is not the first time Turnbull’s attempts to land in Port Lincoln have been thwarted by strong winds – a similar attempt a month ago was also abandoned in the face of bad weather. The winds in Sunday were strong – not strong enough to stop wind turbines from spinning however, as deputy prime minister Barnaby Joyce and South Australia Senator Nick Xenophon like to believe, but enough to provide more than 100% of South Australia’s underlying electricity demand for more than 10 hours on Sunday. According to Dylan McConnell from the Melbourne Energy Institute, who provided the graph above, wind provided more than 100 per cent of the state’s needs from 8:10am to 6:40pm. During that period the price averaged approximately negative $25/MWh. At 2pm on Sunday, wind was (very briefly) was producing 46 per cent more than underlying demand – around 1370 MW of wind and 935MW demand from the grid (which does not include rooftop solar being consumed in homes). As it happened, it was not just windy that day, but also quite sunny. And according to the APVI solar map, rooftop solar PV was producing about 293MW, which means that variable renewable energy sources (wind and solar) were producing 1,670MW. Read More here
19 October @016, Renew Economy, Storm of controversy erupts over AEMO blackout report. Another storm of controversy about the role of wind energy is certain to erupt after the latest report about the state-wide blackout in South Australia by the Australian Energy Market Operator. In its second update, AEMO has pointed the finger at settings on certain wind farms and fossil fuel generators in the events immediately before and after the state-wide outage last month, but the handling of the report has also raised questions about the actions of the market operator itself – both before and after the event. The report dismisses suggestions – mostly from the Coalition and mainstream media – that it was the intermittent nature of wind energy that was the cause of the blackout. But it also underlines the failure of the market operator to make any preparations for the storm that it could obviously see spreading across the state. The AEMO makes clear that it was major voltage disturbances – six in 80 seconds – caused by the collapse of three major transmission lines that led to the blackout. “Five transmission line faults, resulting in six voltage disturbances on the network, led to the SA region black system,” it writes. But – not for the first time – AEMO’s press release and executive summary differs in emphasis to the detailed report, and focuses on the role of the so-called “self protect mechanisms” in wind farms rather than major voltage collapse that followed the collapse of the transmission lines. Even though these self protect mechanisms are just a matter of software and are easily fixed, AEMO’s emphasis has horrified many in the wind industry, who suggest that the market operator is deliberately allowing wind to be blamed even though its report highlights a collapse of voltage that could have been the main cause of the outage. They also point to basic errors in its report, and its failure to take any preventative action as the storms approached. Read More here
