Abengoa mulls 20MW solar tower + storage plant in WA : Renew Economy

Abengoa mulls 20MW solar tower + storage plant in WA : Renew Economy

Already proposed for a long time by the Greens something is finally happening with the help of Spain-based renewable energy giant Abengoa. The company has secured $450,000 in funds from the Australian Renewable Energy Agency to conduct a feasibility study for the project, which would be connected to the South West Interconnected System (SWIS), and could offset expensive grid upgrades, and avoid the cost of transporting expensive fossil fuels.
Just in time, regarding the wrecking ball that is swinging in Canberra.

The WA Government considers power bill change - ABC News (Australian Broadcasting Corporation)

PV as scapegoat for losses from poles and wires

In 2009 Western Power published their proposal for a "Bi-directional Reference Service and Associated Tariff" which then already targeted Households with solar PV to pay for losses incurred by peak power demand - in vain. This proposal had to be published for public comment and - despite its complicated architecture trying to hide the true intent - in the end wasn't put into practice after strong opposition.

This time it isn't that clandestine an approach, the Barnett government is growing bolder. On ABC TV news on one hand the "Energy Minister Mike Nahan says changes to the way household energy costs are structured will not result in higher prices.", on the other hand they state that "rapid increase in the number of households installing rooftop solar panels has contributed to a drop in energy consumption and a revenue shortfall for state-owned power companies.
So the State Government is considering changing the way West Australians are charged for energy use, to protect the long-term viability of the state-owned power grid."
"What we would do is [reduce] the user charge and increase the fixed price," he said.

This means that PV households - which are still connected to the grid but using less power from it than other households - will hardly benefit from a price reduction for the use of electricity and instead will be forced to pay more for poles and wires. They had invested 1000's of dollars earlier in PV attempting to becomes less reliable on the grid, to become a bit more self sufficient, to save a dollar or two, and to do their bit on climate change.

Instead of reading the signs of the times by admitting their power policies have failed and need shifting, e.g. by modernising the grid towards a smart grid (in the non-controlling but load balancing sense) and penalising high power usage the state government tries to save their stone-age assets in favour of modernising an industry, protecting everything that looks like, feels like, and smells like mining; trying to lure the unwary voter with low prices for consumption which in turn would encourage even higher consumption, in these times when use of fossil fuels is indicated left, right, and center.

Don't be fooled by the COALition government (aptly named after their favourite industry?!) trying to taint their true intentions with words such as "We are [also] generating less electricity from coal - that is good, that's what we wanted." The libs have never intended this hence their actions towards the opposite direction:
"Dr Nahan says about 2,000 households are applying to install photovoltaics (solar panels) every week and the government must change its charging system to reflect the trend" ... to recoup lost income for the state budget.

Wind to Double and Solar to Triple in 6 Years : Discovery News

Latest prognosis of the conservative International Energy Agency

... is painting a picture stakeholders in the fossul fuel industry can't be liking very much:
"Total renewable electricity generation grew strongly in 2012, increasing by 8.2% from 2011. In absolute terms, global renewable generation in 2012 exceeded the electricity consumption of China. Part of the strength in 2012 growth stemmed from stronger-than-anticipated hydropower production, particularly in China. Yet it also reflected a continued rapid build-out of non-hydro sources, whose generation rose by 16% year-on-year. Among the OECD regions, non-hydro renewable generation was the second largest source of power generation growth in 2012, expanding by 90 TWh. By comparison, gas-fired generation rose by over 150 TWh, while both coal and nuclear declined."

Read the executive summary of the report in full.

With Tony Abbot (Liberals) vowing to scrap the price on carbon and Kevin Rudd (Labour) going half the same way Australian politicians appear to be still trying to buck the worldwide trend ignoring the will of the majority of Australians who in record numbers have installed solar PV on their roofs.
Question remains why the same majority acts as if there are only the aforementioned political parties which do everything to satisfy the billionaires of the country who run the coal mining, fossil fuel power generation, and media industries.

When Big Coal goes solar | Business Spectator

Are they getting the message?

Or is it more sinister and ruthless, in that they see the good in renewables and decide that the quick buck can be made today with fossils which is for others to pay today and tomorrow?
Maybe it doesn't matter, make of it what you want. I believe it will be an advertisement for renewable energy, especially that the old school is not only using but also displaying use of the new school.
For that bit they deserve to be congratulated.

Don't forget to read the full article, very well done on Climate Spectator.

Dyesol Announces 'Quantum Leap' In Dye Solar Cell Efficiency : Renewable Energy News :

In 2010, solid-state DSC performance was at just 5%, but today ...

... the performance that has been achieved is a lot higher: 11.3% at full sun!

While this is still way less than the "normal" panel efficiencies achieved today, it is of particular interest as this technology doesn't rely on being installed as a panel.
"DSC technology is described by the company as "artificial photosynthesis" that uses an electrolyte, a layer of titania and ruthenium dye deposited on glass, metal or polymer substrates."
But it has even more advantages, about which you can read on Energy Matters

New Battery Efficiently Stores Solar and Wind Energy | The Daily Fusion

New Battery Efficiently Stores Solar and Wind Energy | The Daily Fusion

Scientists from the U.S. Department of Energy’s (DOE) SLAC National Accelerator Laboratory and Stanford University have developed a relatively cheap, long-life “flow” battery that can be used to mitigate power fluctuations from solar and wind energy plants, therefore enabling them to become major suppliers to the electrical grid.

...
The new Stanford/SLAC battery design uses only one stream of molecules and does not need a membrane at all. Its molecules mostly consist of the relatively inexpensive elements lithium and sulfur, which interact with a piece of lithium metal coated with a barrier that permits electrons to pass without degrading the metal. When discharging, the molecules, called lithium polysulfides, absorb lithium ions; when charging, they lose them back into the liquid. The entire molecular stream is dissolved in an organic solvent, which doesn’t have the corrosion issues of water-based flow batteries.
“In initial lab tests, the new battery also retained excellent energy-storage performance through more than 2,000 charges and discharges, equivalent to more than 5.5 years of daily cycles."

Suntech Bankrupt and Bosch Dropping Out of Solar | The Solar Drop - DIY Solar and Solar Energy News

Good news for consumers, but somehow frightening to watch how the companies which did the heavy lifting in making Solar PV affordable have to make way for others.
Well, who knows how strongly this was a matter of manipulation versus forces of the market?
Maybe a sign of what might happen to the fossil fuel industry some time down the track?
