Very important to realize the Australian electricity market is like Enron on steroids. The main players have been manipulating  availability to create price spikes.

Even relatively small amounts of storage like the 4MWh of the new project break this and prevent wide scale price manipulation. This storage is not about smoothing solar or wind but rather all about being able to jump in to prevent coal and gas generators from exploiting a terribly designed market.

I don't know how the energy market works in Australia.  There was a discussion about adding some storage to wind and solar farms in the US so that the farms could sell a guaranteed 15 minute block of electricity to the grid.  X kWh for 15 minutes without interruption.

They run on 5 minute blocks and the result is quite erratic.

Select 5 minute top right side and you can then select regions. Small storage allows you to always have power to sell for all the 5 minute spikes of very high priced electricity.

4MWh batteries obviously doesn't make it fully dispatchable. Maybe it doesn't need to be dispatchable if the supply reasonably matches demand perhaps it doesn't make the need for dispatchable generation much or any worse?

The allegedly United Kingdom's Government finally seems to be getting around to the idea of trying to match demand to supply instead of the other way around. An overview of my visit to the BEIS basement last week:

I'm not exactly sure why, but the panels in the above photo appear to be a temporary emergency installation, with a more permanent solution to follow. It might be less expensive to permanently install solar panels elsewhere, rather than to replace the parking?

Since the need is urgent the added expense is a non-issue.

Looking at a couple of pictures on the web it looks to me that this is a temporary installation.

It looks like the racks and Powerpacks are simply sitting in the parking lot. 

Hopefully we'll see some storm hardened racking coming later.  Like was used in the solar farm that came through the hurricane with no (apparent) damage.

Quite so, and possibly a model for future emergency power deployments. No flammable fuels, no noisy, smelly, unreliable generators, easy to store, relatively light, scalable, and no expiration date for the fuel.

I'll only attack the "but it took them a whole week", meme.


It took a week when no planning for this adaptation had taken place, and when parts, materials and crew were imported from the mainland.


Imagine how much quicker your local Tesla Team would be when installing panels and batteries that were in stock and that were familiar to the local installation team(s). Who knows, they might even practice to shave seconds off their previous best.

Richard Branson’s green energy plan for Caribbean may include debt relief
Quote
A plan by British billionaire Richard Branson to lead a post-hurricane rebuilding effort in the Caribbean, with a focus on clean energy projects, may include debt relief negotiations mediated by the International Monetary Fund.

Branson is spearheading a plan to help Caribbean nations recover after Hurricanes Irma and Maria ravaged several islands. The centerpiece of the plan is a push to replace outdated fossil-fuel power grids with renewable energy systems that can withstand extreme weather and boost economic development in Caribbean.

For the past month, the founder of the Virgin Group conglomerate has been in talks with some of the world's top multilateral lenders and foundations to set up a fund to finance what he called the Disaster Recovery Marshall Plan – a reference to a program to rebuild Western Europe after World War Two.

The effort focuses on "a green energy revolution" to make Caribbean economies more sustainable, Branson said. ...

St. Louis, Long a Coal Capital, Votes to Get All of Its Power From Clean Sources

By 2035!  Wow.  It's not enforceable as is... but is particularly significant because the city is home of "many of the nation's largest coal companies, including the industry's two giants, Peabody Energy and Arch Coal."  The city currently gets about 95% of its power from fossil fuels and nuclear.

Yeah, we'll see how this goes when we try to get concrete commitments and plans. Ameren, the power supplier for the region, has on the order of 3% renewable energy in its electricity production mix right now and recently published its long range plan to hit about 13% RE in 2030.

2030.

The US overall RE contribution is greater than 13% today.

There are significant financial ties between Ameren and Peabody/Arch coal companies. I don't see Ameren being very interested in dumping coal as a primary energy source without a LOT of financial incentives. Even if wind/solar is cheaper.

Elon Musk says ‘we’ll work harder’ about Tesla’s effort to solve Australia’s power issues
Quote
According to the 60 Minutes episode... it has led to record number of late bills and disconnections, which results in some low-income families having to choose between power and food.

Musk was surprised by the problem:

“Australia has so many natural resources that even if you go the fossil fuel route electricity should be cheap.”

He became emotional when presented with this growing problem affecting families. He responded:

“I didn’t expect that… We’ll work harder”

Wind powered a record of nearly 200 million European households on Saturday
Quote
On Saturday, a record 24.6% of total electricity came from wind power sources in the 28 countries of the European Union. The majority of this wind electricity was generated onshore (88.7%) vs offshore (11.3%).

With Europe moving into the high wind production winter period, we expect a new season of records being broken. And with massive scale construction continuing for offshore wind farms, these records of 2017 will soon look quaint.

The amounts of electricity generated were enough to power 197 million European households or 68% of all industrial electricity needs. As of the end of 2016, there were 153.7 GW of installed wind power capacity in the EU: 141.1 GW onshore and 12.6 GW offshore. Europe has about 500 million total people, with a land mass very close to that of the USA. ...

According to the Gridwatch figures, as compiled by the Renewable Energy Foundation (which in spite of the name is anti-renewable, pro nuclear), the UK produced 3,822 GWh or 17.3% of its electricity from wind power in October. This smashes the previous monthly record of 12.4%:

http://www.ref.org.uk/fuel/index.php?tab=month&order=seqdate&share=Y&dir=desc

As these figures don't include embedded wind, which adds another 25-30%, the real figure was probably over 20%. For the year to date, the figure is running at 11.2%, equivalent to around 14% including embedded wind.

USITC recommends tariffs on solar panels:

https://www.usitc.gov/press_room/documents/solar201_remedy_commissionerstatements.pdf

sidd


Welllllll
Canada is not to be included under this particular tariff, sooooo


Perhaps we (Canadians) could purchase a brand new Chinese solar panel factory, fully fitted out with automated ordering, receiving, manufacturing, packaging, and loading. The 4 Canadian employees would handle security on a 24 hour basis, and any robotics maintenance required would be outsourced to a group familiar with the mandarin language service manuals.


If properly sited all raw materials would enter through the northern shipping docks, while the southern docks would align with the international border, allowing shipping via American trucks and rail while eliminating any cross border transportation.


A win-win solution that should please everyone involved.

There's already a Canadian Solar company.  But they manufacture their panels in China.

Just pack up your stuff and ship it home.

Rural Illinois.  Thinking outside the, um, box.  ;D

Combination cemetery and solar panel farm proposed for Fondulac Township
Quote
The solar panel project would occupy 20 acres on the back side of the houses on Dundee Road; the cemetery would occupy 17 acres behind the houses on Cherry Lane. Trajectory would operate about 7,000 solar panels, 3-feet by 6-feet, laid side by side on the property, Carson said. The panels rotate, following the track of the sun throughout the day.

Trajectory will lease the property at a rate of $800 per acre a year with a 2 percent escalation clause for 25 years. That calculates to $461,000 of township revenue over the course of the lease. ...

Yes, in a way, but for wind power some of the distributed generation is at much bigger wind farms than distributed solar. Another way of looking at it is any behind-the-meter generation that shows up as a drop in demand rather than as an increase in generation. I base my figure on Gridwatch, which claims that you should add 30% for embedded wind, and was set up by someone anti-wind, so I don't think there's a big bias in favour of wind. However, I suspect that's too high these days, because newer wind farms are less likely to be "embedded" . I'll try to find some more data.

This is great!  Worth posting the Google translate version in English:

Loíza opens a community solar laundry
Residents can wash two batches at no cost
Quote
Loíza inaugurated her first free community solar laundry , in order to avoid the contamination of rivers and streams and reduce the health risks due to the debris and dead animals left by Hurricane Maria in these bodies of water.

Located in the Baptist Church of Medianía Alta , the laundry was built on Friday thanks to the help of the group of volunteers Por los Nuestros and several companies, explained today the mayor of Loíza, Julia Nazario Fuentes, in a press release.

"We are more than grateful for the group Por los Nuestros, its founders and volunteers, who have been very generous in helping our families in the region, where some lack drinking water and others lack electricity," said Nazario Fuentes.

The Whirlpool company donated ten high-efficiency washing machines, while the German company Sonnen donated a system of photovoltaic panels and batteries to supply the power to the washing system.

The European company carries out the service through its largest distributor and installer in Puerto Rico, Pura Energía, to install the solar panels that will power the washing machines.

Similarly, the Procter & Gamble company will provide detergent free of charge.

"We are committed to the recovery efforts in Puerto Rico, and we understand that access to clean and renewable sources of energy is crucial for a quick and safe recovery after hurricane Maria," said Adam Grenter, of the German company. Sonnen.

The group Por los Nuestros was created by communicator Jay Fonseca and doctoral student of environmental chemistry Alexander Rodríguez, who together with various organizations, proposed to build laundries with solar energy to avoid pollution of rivers and streams and reduce health risks.

"Today we have another bright example of how much we can achieve through partnerships with the private sector, churches and nonprofit organizations What we are seeing today is an example of the importance of getting up and moving towards self-sufficiency , because we have plenty of energy and capacity, "said Nazario Fuentes.

Laundry hours will be between 8:00 a.m. and 5:30 p.m., with a limit of two batch of clothes per family

Rural Illinois.  Thinking outside the, um, box.  ;D

Combination cemetery and solar panel farm proposed for Fondulac Township
Quote
The solar panel project would occupy 20 acres on the back side of the houses on Dundee Road; the cemetery would occupy 17 acres behind the houses on Cherry Lane. Trajectory would operate about 7,000 solar panels, 3-feet by 6-feet, laid side by side on the property, Carson said. The panels rotate, following the track of the sun throughout the day.

Trajectory will lease the property at a rate of $800 per acre a year with a 2 percent escalation clause for 25 years. That calculates to $461,000 of township revenue over the course of the lease. ...

Just triggered an idea. You know how children will plant a tree or install a park bench in memory of a lost parent? Why not have memorial solar panel installations?

China continues to lead the world in wind turbine installations and electricity generated. There goal is to have 15% of electricity generated by wind by 2020, a nearly 4 fold increase over 2016.
China has also identified wind power as a key growth component of the country's economy.

http://newenergyupdate.com/wind-energy-update/china-fund-boost-wind-turbine-trade-exports-grow

"Because Chinese wind manufacturers are now capable of producing 40 GW worth of turbines annually, while the Chinese government’s target is to install just 20 GW of new capacity per year between 2015 and 2020, they are aggressively growing their export markets to meet the rapidly growing world demand for wind turbines.

Because of this, Asian installed wind power capacity rose to 142GW at the end of 2014, surpassing Europe where capacity totalled 134GW, according to a report by the Global Wind Energy Council (GWEC). Asia will continue to lead the growth in wind power, providing 40-45% of the annual global going forward, GWEC said.

GWEC is expecting an additional 140 GW to be installed in Asia between 2014 and the end of 2019, a doubling of the existing installed capacity.

China wind turbine companies see greater growth opportunities outside of China based on recent export figures, according to a report from CCM. A diverse group of countries are buying Chinese-made turbines. The top ten buyers include large economies such as the US, Australia, and Italy, but also Panama, Romania, and Ethiopia, according to CCM.

Exports accounted for just 4.3% of Chinese turbine manufacturers’ total sales volume in 2013, but this figure is rising rapidly and this will increase competition in the international wind market. Chinese exports more than tripled between 2011 and 2013, whereas domestic demand fell slightly during that period, the report said."

Yes, in a way, but for wind power some of the distributed generation is at much bigger wind farms than distributed solar. Another way of looking at it is any behind-the-meter generation that shows up as a drop in demand rather than as an increase in generation. I base my figure on Gridwatch, which claims that you should add 30% for embedded wind, and was set up by someone anti-wind, so I don't think there's a big bias in favour of wind. However, I suspect that's too high these days, because newer wind farms are less likely to be "embedded" . I'll try to find some more data.

I should clarify that this embedded wind power is fed into the grid, but into the local, low-voltage distribution grid, rather than the high-voltage national transmission grid. So it is behind the meter from the point of view of the national grid, but it isn't really distributed distribution in the same way as a rooftop solar array on someone's house.

New Study: 100% Renewable Electricity Worldwide is Feasible and More Cost-Effective than the Existing System
Quote
A global transition to 100% renewable electricity is not a long-term vision, but already a tangible reality, a new groundbreaking study by the Lappeenranta University of Technology (LUT) and the Energy Watch Group (EWG) shows. The study was presented on November 8, 2017 during the Global Renewable Energy Solutions Showcase event (GRESS) on the sidelines of the United Nations Climate Change Conference COP23 in Bonn.         

The results of the study are revealing: A global electricity system fully based on renewable energy is feasible at every hour throughout the year and is more cost effective than the existing system, which is largely based on fossil fuels and nuclear energy.

Existing renewable energy potential and technologies, including storage can generate sufficient and secure power to cover the entire global electricity demand by 2050[1]. Total levelised cost of electricity (LCOE) on a global average for 100% renewable electricity in 2050 is €52/MWh (including curtailment, storage and some grid costs), compared to €70/MWh in 2015

“A full decarbonization of the electricity system by 2050 is possible for lower system cost than today based on available technology. Energy transition is no longer a question of technical feasibility or economic viability, but of political will”, Christian Breyer, lead author of the study, LUT Professor of Solar Economy and Chairman of the EWG Scientific Board said.

A transition to 100% renewables would bring greenhouse gas emissions in the electricity sector down to zero and drastically reduce total losses in power generation. It would create 36 million jobs by 2050, 17 million more than today.

”There is no reason to invest one more Dollar in fossil or nuclear power production”, EWG President Hans-Josef Fell said. “Renewable energy provides cost-effective power supply. All plans for a further expansion of coal, nuclear, gas and oil have to be ceased. More investments need to be channeled in renewable energies and the necessary infrastructure for storage and grids. Everything else will lead to unnecessary costs and increasing global warming.”

The key findings of the study:

Existing renewable energy potential and technologies, including storage can generate sufficient and secure power to cover the entire global electricity demand by 2050. The world population is expected to grow from 7.3 to 9.7 billion. The global electricity demand for the power sector is set to increase from 24,310 TWh in 2015 to around 48,800 TWh by 2050.

Total levelised cost of electricity (LCOE) on a global average for 100% renewable electricity in 2050 is €52/MWh (including curtailment, storage and some grid costs), compared to €70/MWh in 2015. 

Due to rapidly falling costs, solar PV and battery storage increasingly drive most of the electricity system, with solar PV reaching some 69%, wind energy 18%, hydropower 8% and bioenergy 2% of the total electricity mix in 2050 globally.

Wind energy increases to 32% by 2030. Beyond 2030 solar PV becomes more competitive. The solar PV supply share increases from 37% in 2030 to about 69% in 2050.

Batteries are the key supporting technology for solar PV. The storage output covers 31% of the total demand in 2050, 95% of which is covered by batteries alone. Battery storage provides mainly diurnal storage, and renewable energy based gas provides seasonal storage.

Global greenhouse gas emissions significantly reduce from about 11 GtCO2eq in 2015 to zero emissions by 2050 or earlier, as the total LCOE of the power system declines.

The global energy transition to a 100% renewable electricity system creates 36 million jobs by 2050 in comparison to 19 million jobs in the 2015 electricity system.   

The total losses in a 100% renewable electricity system are around 26% of the total electricity demand, compared to the current system in which about 58% of the primary energy input is lost.

The study “Global Energy System based on 100% Renewable Energy – Power Sector” will have major implications for policy makers and politicians around the world, as it refutes a frequently used argument by critics that renewables cannot provide full energy supply on an hourly basis.

Nantucket island, off Cape Cod, Massachusetts.

Tesla to support sleepy island’s aging infrastructure with back-up energy solution
Quote
Tesla will be supporting Nantucket’s aging back-up power system through the installation of a 48MWh Powerpack battery energy storage solution. The sleepy island town, located 30 miles off the coast of Massachusetts and approximately 100 miles from Boston, has become a popular summer destination in recent years and, as a result, experiencing significant increases in demand for electricity. While this would ordinarily be seen as positive news for Nantucket’s 10,000 residents, part of the island’s electrical infrastructure that’s nearing its end of life sees it differently.

Electricity flowing into Nantucket is supported by two undersea transmission lines that extend from the mainland near Cape Cod to the island. Two diesel generators that can each provide 3MW of power serve as a partial energy back-up solution in the event that one of the underwater transmission lines fail. Amid an increase in tourism on the island and expectation that the generators will need to be replaced within 12 years, utility company National Grid devised a plan that would demonstrate the region’s commitment to sustainability, while also provide a cost-effective and reliable back-up power solution for the years to come: install a battery energy storage system (BESS) by Tesla. ...

That would be great.  However, I noticed that they made some rather rosy assumptions in their costs for future photovoltaics between now and 2050 that allows them to supply electricity at much lower costs than other sources, resulting in PVs supplying 69% of future electricity demand.

Lowest costs for utility scale PV are already much lower than the €52/MWh assumed for 2050 so these low prices will definitely be the norm by 2050.

Chile has received two bids for electricity from large-scale solar projects, in 20 year contracts, at prices under 2.5¢/kWh at a recent national auction. The lowest bid was 2.148¢/kWh.

On October 3rd, Saudi Arabia announced a bid of 1.79¢/kWh for a 300MW farm

A new contract signed by Arizonan utility Tucson Electric Power (TEP) has set a new low price record for large-scale solar power in the country.

TEP has entered the US into a new realm of solar at below 3 cents/kWh, after similar prices have been regularly achieved in other countries such as Dubai, Chile and Mexico for over a year now.

TEP signed a 20-year contract with NextEra Energy to buy solar at a “historically low” price of sub US$0.03/kWh. This is reportedly the lowest price for solar PV that has been achieved in the US to date. The utility said that the price is “less than half as much as it agreed to pay under similar contracts in recent years.”

https://www.pv-tech.org/news/sub-3-solar-in-arizona-marks-us-lowest-price-for-solar-pv-to-date

The Arizona price probably is lowered by federal subsidies.  To get a rough idea of the unsubsidized price one could multiply "below 3 cents" by 1.3 and end up at something not much higher than 3 cents.  3 US cents is about 2.5 euro cents.

Prices are coming down incredibly rapidly.  Recently I saw a picture of the support posts for solar panels being 'screwed' into the ground.  This would do away with any need for concrete.  Just posts with large screw threads on the bottom.  This is a technology commonly used for anchoring guy lines for power lines.  Installation is simple and quick.  Panels now snap into place on racks, no using machine screws and nuts.  Panels are plug and play - just quickly hook them together like plugging into an extension cord.
 Developments like this can quickly drive down costs.

Wind is likely to take a big cost drop.  DOE research finds that by moving from 80 meter hub heights to 140 hub heights we can expect capacity factors to rise from the current 40-something percent level to 60 percent or better.  This would mean a 50% increase in electricity produced for only the cost of some more steel tower sections.  Unsubsidized wind in the US is now running under 3 cents/kWh in good wind sites.  A 50% increase in output with little additional capex could mean unsubsidized wind under 2 cents/kWh.

Improvements in such seemingly mundane things as the connectors enabled Tesla Solar Roof Tiles to have a warranty of “infinity or until your house falls down.”  And an install time near that of a traditional solar roof.

New inverters are designed to let you power your house when the grid goes down — without batteries.

“First Solar and the State of California verified that inverter technology could in fact offer these grid services without energy storage on a large-scale.”

Quote
“Most customers are unaware of this limitation (automatic shut off) with today’s solar technology. So, to address this limitation we have invented a microinverter technology that is completely grid agnostic. This means that even if the grid fails and there is sufficient sunlight, the Enphase system will continue to produce energy and meet the demands of the home or business. The Enphase microinverter system’s capabilities further enhanced when the Ensemble technology is incorporated into our AC battery storage solution.”
