11 November 2016, Energy Post, Lumenaza creates regional electricity markets: “We want to connect up all 1.4 million solar PV producers in Germany with consumers locally”. A new software platform in Germany lets utilities buy and sell “regional electricity” by connecting up small producers with consumers. Start-up Lumenaza, founded three years ago, meets a growing demand for transparency, explains CEO and founder Christian Chudoba in an exclusive interview with Energy Post. Unlike a typical virtual power plant, Lumenaza targets tiny producers such as owners of rooftop solar. Its goal is to connect up all of Germany’s 1.4 million small power producers. Lumenaza was inspired by a family party in southern Germany. Christian Chudoba, today the company CEO, realised that everyone around him was generating electricity, but there was no way of buying this local produce. In response, he founded co-Lumenaza with his Siemens colleague Bernhard Böhmer in February 2013. Three years later, the company offers utilities a software platform that directly connects up small, local producers with consumers in the same region. Eight projects are up and running and another 3-4 expected by the end of the year. Chudoba comes from the world of software telecommunications at Siemens. He had the business idea; Böhmer, today Chief Technology Officer, supplied the software expertise. Oliver March, now CFO, jointed one year later bringing in the financial expertise. The two have created a product that they believe can help improve the acceptance for building more renewables in Germany. Just as consumers like to buy local, producers “like the idea of knowing where the electricity they produce is going”, says Chudoba. We call it a marketplace or “utility-in-a-box” software. The platform buys the electricity from local [renewables] producers and sells it to consumers. Read More here

11 November 2016, The Conversation, Firestorms: the bushfire/thunderstorm hybrids we urgently need to understand. Fire has been a driving force across Australia for millennia. Indeed, the health of many of our ecosystems is intrinsically dependent on fire. But bushfires are also one of our most frequent natural hazards, with a total cost estimated at A$340 million per year. In the past decade or so, extreme bushfires in southeastern Australia have burned more than a million hectares, claiming more than 200 lives and over 4,000 homes. Similar losses in other major urban areas have prompted questions about whether we are seeing a shift towards a significantly more hazardous fire regime, characterised by increasing fire frequency and intensity, and the development of catastrophic “firestorms”. While these extreme bushfires account for only a very small percentage of fire events, they are responsible for the lion’s share of bushfire-related losses. In contrast to typical bushfires, which spread across the landscape as well-defined burning fronts with smoke plumes perhaps a few kilometres high, extreme bushfires exhibit deep and widespread flaming and produce smoke plumes that can extend 10-15km into the atmosphere. At these altitudes, bushfire plumes can actually develop into thunderstorms (hence the term “firestorm”). As such, extreme bushfires become much more difficult for emergency services to handle, making them all but impossible to suppress and their spread difficult to predict. Read More here
20 July 2016, Renew Economy, ACT opens solar scheme to low-income households. The ACT’s $2 million low-income solar scheme has opened for registrations of interest from eligible households, wishing to install rooftop PV but unable to afford the upfront investment. ACT environment minister Simon Corbell said on Wednesday that people living in low-income households in the Territory could now put their hands up to take part in the pilot program, which will run for the next four years. The program, which is expected to start installing systems in late 2016 or early 2017, will be run as a pilot, initially, to determine the best approach for future delivery, and will be developed in conjunction with key stakeholders including ACT Housing, community welfare organisations, and low-income loan groups. The opening of the renewables scheme – one of many being successfully rolled out in the ACT – comes at a time where rooftop solar and wind energy are being accused of driving up power prices in some parts of Australia. But as we have noted on various separate occasions, the accusations, coming mainly from conservative politicians and media outlets, are ill-informed and misdirected, and ignore the many benefits solar and wind have brought to the national electricity market. ACT’s Corbell, who is the mastermind behind the territory’s ambitious 100 per cent renewable energy target, has demonstrated these benefits very well, and is poised to deliver massive savings to consumers in the nation’s capital, as this article explains.

12 July 2016, Renew Economy, ACT could make windfall gains from bold 100% renewables target Who is the smartest energy minister in the country? At the moment, you would have to say it was the ACT’s Simon Corbell, the mastermind behind the territory’s bold 100 per cent renewable energy target, and who is poised to deliver massive savings to consumers in the nation’s capital. Indeed, if current wholesale electricity prices continue as they are across Australia, the ACT will not just have zero emissions electricity by 2020, it may also be getting most of it for free. This extraordinary situation arises out of the nature of the contracts that the ACT government has written with the project developers who have won its unique reverse auction tenders. The ACT has locked in fixed prices at between $77/MWh and $92/MWh for a total of 400MW of wind energy capacity so far. If the wholesale price is below those contracts, the ACT government pays the difference. If it is above, the ACT electricity utility ActewAGL receives the excess. In the past two months, wholesale prices across Australia have gone through the roof, mostly because of soaring gas prices (at record levels in most states), and supply constraints. Some of these rises have already been passed on to consumers. The first of the ACT commissioned wind farms, the 19MW Coonooer Bridge project in Victoria, opened earlier this year and gets a guaranteed $81.50/MWh from the ACT. But prices in Victoria have regularly jumped above $100/MWh in the past two months. Read More here
