Electrek green energy brief: Battery plus solar pricing from NREL, South Australia with largest battery plus solar, more

Site default logo image

New NREL report details installed costs and deployment barriers for residential solar+storage – If you really want to do some research on what your battery system is going to cost, and why, start here. NREL reports are always top notch – I distribute them often (and maybe some of you should download this stuff before Pruitt deletes it).

South Australia getting 100MW energy storage plus 330MW of solar – Is 100MW the largest battery system connected to a power grid? How do they go from announced last night to built before end of year? Or that’s right – solar + storage. And, most interestingly, it isn’t Elon Musk doing the deal. These Australians move fast when the electricity stops running.

Electrek green energy brief: Trump attacks Clean Power Plan, 5GW of batteries for Australia, more

Site default logo image

Trump signs executive order to review Clean Power Plan – A couple of interesting points within the article – 1. The EPA, per the courts, is obligated to protect against CO2 – which has been defined as a pollutant. It seems that if the current administration were to simply get rid of the Clean Power Plan, they’d be open to law suits. 2. Scott Pruitt, the new EPA chief that pretty much works for the fossil fuel industry, wrote a version of regulations for the coal industry that forced an ever so slight increase in efficiency. We can see a future pathway – a toothless replacement plan, versus an absolute rescindence of the law.

31.3 percent for a fully integrated silicon-based multi-junction solar cell – Space age stuff these days, unless you’ve got a dual axis solar tracker and you’re ok with a slower return on investment. These multi junction technologies – multiple layers of solar cells absorbing sunlight – will break through to the mass market one day. The recent 26.3% solar cell was two layers – both silicon. This cell is three layers with different product types. Being discussed in the article is how to bond the solar cells – maybe that’s where the real breakthroughs are these days.

Electrek green energy brief: Largest artifical sun, hundreds of clean energy laws, more

Site default logo image

World’s largest artificial sun (original source)- Its purpose is to test ways to generate hydrogen from water using sunlight. There is a lot of thought about what we could do with hydrogen storing excess intermittent energy – though lithium ion is taking the early lead. Personally, I’m starting to lean toward lithium+solar because of the solid state nature of the two technologies (this picture really got to me), however, there could be places where liquid fuels make sense.

Hundreds of Clean Energy Bills Have Been Introduced in States Nationwide This Year – Hundreds of millions of dollars are being spent by utilities in a concerted effort across the country to influence the political process against.

Electrek green energy brief: Walking on solar panels, big oil loves big offshore wind, more

Site default logo image

Big Oil throwing down for Big Offshore Wind – If there is anyone with an expertise and the cash needed to build ocean based hardware that can produce long-term consistent revenue, it would be the engineers that have deployed oil wells in the deep seas for decades. Ocean-based wind can sometimes run for 50% of the time – and with floating units coming next, big oil with its big capital might see its most powerful weapon against the coal industry be renewable. I’ll take it from where ever it comes.

Partisan reactions to Trump over environment – Large chunks of the US electorate have shifted their views on future of the environment since Trump came into office. Republicans toward believing the future environment is getting great attention and will improve, while Democrats see it getting worse. With Trump and Republicans seeing poles like this I don’t expect them to be very interested in legislative measures.

California solar + wind record high at 49.2%, renewable electricity peaks above 56%

Site default logo image

Solar power in California started setting production records on February 24th – production peaks have continued to occur since then. On Thursday of last week renewables broke 56% of total demand. This record is partially the result of a national 2016 installation boom of greater than 14GW of solar power that California took 35% of.

According to the daily report on March 23rd, solar peaked around 11.16 AM – three minutes before the solar + wind peak of 49.2% and nine minutes before renewables peaked 56.7%.

Electrek green energy brief: Florida politicians sticking it to voters (again), “Clean Coal” plant = economic failure, more

Site default logo image

After Florida voters approve solar law by 73%, utilities attempt to add on solar limiting rules – In the last election in Florida, voters decided to support tax breaks for commercial companies going solar. Florida politicians decided that the law – instead of focusing on tax breaks – ought also add additional requirements, strategically chosen, to make residential solar a little more complex. One of the strange aspects of the law is that it says you cannot use past history prices to predict future energy savings. Best part is that one of the politicians pushing the law says we don’t actually need the law today in Florida since there aren’t any contractors breaking the law – but you know – just in case someone might want to break this law, we ought make a law.

Southern Company Says $7B+ ‘Clean Coal’ Kemper Not Viable as Coal Plant, Blames the Public Service Committee – At the end of spending $7B a clean coal plant is said to not be economically viable burning coal – and of course, it isn’t the technologies fault but those who are hoping to protecting rate payers. Coal has significantly cleaned itself relative to pollution of yesteryear – wikipedia says coal plants are 77% cleaner than they used to be. And imagine, even so much cleaner coal is releasing twice as much CO2 per kWh as natural gas.

Electrek green energy brief: WorldBank loan at 0.25% for 750MW, Trump says no to ‘carbon tax’, more

Site default logo image

750MW solar park to get 0.25% loan from World Bank – This is just below the going rate for banks that borrow directly from the United States (or really rich people who have hard collateral). The World Bank does have political reasons for giving a loan like this and the loan is probably backed by India. Nonetheless, big names like this giving big money like this are important – for one, that one group is doing it means others will soon follow. And that means 1GW solar power plants will get built a lot more often.

The Trump Administration pushing back against carbon tax – Technically, anything this group says out loud doesn’t matter relative to truth or long term reality – however – it does represent their current philosophical positions. And that is a good thing to know. However, has the Trump administration ever heard of a ‘carbon dividend‘?

System monitoring software getting Australian attention – Posting this because of a few data points in the article – the main one 15% system losses in residential solar systems due to not recognizing downtime. Holy lost revenue! That’s huge. This needs to be tied directly to my heart – if my solar system isn’t working at high noon I need a little jolt.

Electrek green energy brief: SunPower CEO doubtful on Musk’s ability to deliver, Pay as you Go Solar for Africa, more

Site default logo image

SunPower thinks it’ll be a challenge for Musk to deliver PV at the prices suggested – Two things – 1. SunPower sells the most expensive – and maybe best quality – solar panel a regular person can buy. 2. SunPower has been selling solar panels for a long time. My default reaction with Musk is to expect that maybe it’ll take a little longer (month? six?) to arrive and roll out a bit slower (80,000 vehicles in 2016 versus almost 100,000 as guidance) – but, it will arrive and it will be priced right and it will change the game. I can accept that – I would celebrate that.

California looking to specify renewables for peak moments – The gist – California legislators are attempting to restructure the power market so it makes more sense economically for renewable energy to be applied to the very expensive peak demand areas. The reason we ought watch these types of legislation is that places like California are at the cutting edge of power markets and how we’re going to monetize clean energy. Funny that we’ve so quickly progressed from renewables can’t scale and are expensive, to there are too many renewables and they’re so cheap we need to change everything.

Electrek green energy brief: Solar glass as art, how to create 26.3% solar cell, and more

Site default logo image

The header image is found on spot.com. It is a piece of solar glass art made by Sarah Hall. I’ve never seen anyone make such gorgeous solar art that generates electricity. Combined with the products we’re seeing from groups like Onyx Solar – it seems new construction with customized solar in the place of glass – could be economically sound (everything I do in solar involves return on investment). And that economically sound glass could be quite beautiful.

How to create a 26.3% solar cell – The image of an almost pure black solar cell is fitting. Developer of cell says manufacturing timetables haven’t been discussed. 2020? Later probably. In real life, 30 standard 280W solar panels taking up 550 sq ft of roof space would cover the average 2.6 family household – if the efficiency increases from 16% to 26% (65%!) you’d need about 18 solar panels taking up 330 sq ft of roof space. There are a lot more surfaces that are 330 sq ft then there are 500 sq ft plus. One of the major arguments I get is that they want more electricity out of the same space – this is the path.

Electrek green energy brief: US at G20 calls climate change ‘Waste of money’, Wind 33% cheaper than 16% of US coal, 1GW solar plant plus factories for Turkey, more

Low cost wind displacing coal – 56GW of coal at risk, that’s a big number – about 16% of the current stock around 339GW of coal. If wind runs at a 35% capacity factor and coal is around 60%, that’d mean about 96GW of wind to replace the at risk product – that would more than double the current US wind capacity. That’d be a lot of progress

East Coast off shore wind energy headlines coming daily it seems – Maryland weighing two wind proposals, 750MW vs 120MW – North Carolina, New York, Maryland and Massachusetts have all expressed interest in joining Rhode Island in the off-shore wind game. With the Department of Energy saying we’ve got greater than 2,000GW of off shore wind potential on US coasts – and that with HVDC lines that wind could meet 30% of US electricity needs, this might be a big game gearing up. Any advice on how to get off shore wind into a well balanced portfolio?

Electrek green energy brief: Offshore wind survives 70mph, Australia needs 6X Musk’s offer, India’s 15 month doubling, more

India doubling solar capacity in 15 months – From 10GW to 20GW – You know why this solar revolution really could happen, because it seems the revolution slowly moves around the world – Germany, Italy and Spain, then the USA and Japan, then China that leads – and now India stepping onto the big field. Of course, there are others growing – Australia and Africa and the Middle Eastern oil countries. It seems as I hear about slowdowns in Germany and China as they build out their grids, India picks up. And once China and Germany fix their grids, their volumes will explode again. Virtuous cycle spreading across the globe in a complex pattern that we’ve seen before with many other technologies that come to dominate.

600MW needed to fix Australian grid issues – And then read this on the broader effect/consequences of Musk and this Australia battery play. Per the BNEF article, the 100MW is going to cost South Australia $169M – if they need 600MW per the Bloomberg article – then that totals $1B – spread that over 1.7M people and 10 years – $5/month/person. With big solar signing the biggest deals yet in Australia – technology like this allows this region to cut dependence on fossils and jack their renewable – maybe $5/month makes good sense.

Electrek green energy brief: Energy monopolies in Ohio, Florida slow kid in solar class, Sunrun+Storage, more

Energy monopolies driving Ohio prices upward (not renewables) – Because of ‘gold-plating’ and legislative bill riders electric utilities have made tens of billions extra since 1999 per a study. Gold plating is the process whereby a utility is given a guaranteed return on investment – via increasing rates – on all money spent. Buy a new truck? Charge the ratepayers + 10%. Redo the CEOs office? Charge the ratepayers +10%. No joke. The common refrain we hear is that adding renewables to the power grid is driving the price – except we know this isn’t true.

FPL (South/Central FL electrical utility) awards 600MW of solar power contracts in Florida – I am happy to see my home state of Florida installing many megawatts of solar power at $1.50/W (I bet the wind code of 135mph+ increased the price of the install by ¢10/W or more). Of course, FPL is partially a crook when it comes to manipulation of the general public to keep a monopolistic stranglehold on electricity generation. Florida, The Sunshine State, must be on the top ten list of solar power! Right? Massachusetts, New York and New Jersey are though…not the Sunshine State. And just in case you were wondering – Florida isn’t even in the top ten of cumulative solar power, being as how it is the third largest state in population – this is whack.

Quality of service figures for the electricity networks of Germany – The Bundesnetzagentur uses the information to calculate the system average interruption duration index (SAIDI) – This value has fallen from 21 minutes/year to 12 minutes/year. Germany takes on significant intermittent renewable energy in the form of solar power and wind. With the support of surrounding power grids, increased engineer experience, upgrades to the power grids, and more battery systems (50,000 today), zee Germans have been able to continually increase their grid’s up time – even as renewables keep increasing (more slowly today – but still growing).

Net metering 2.0 slows down California’s residential solar market – And that is the way it is supposed to work. If the most energy is being used in the early evening (the duck curve), then we need fine tune our systems. Time of Use helps us better understand pricing as private people and business, we invest appropriately, and our challenges will shift.

JA Solar posts 16% revenue, 25% shipment year-on-year increase in 2016 – 5.2GW of solar sold at $2.3B is ¢44/W for solar panels. Gross margins were down to 14% from 17% – I’ve always been taught that healthy, long term business needs margins closer to 25-30%. Interesting note from the article – a new $1B solar cell factory in Vietnam was put on hold due to environmental issues.

Price Drop across Multi-si Value Chain Continues and Embroils Price Trend of Mono-si Products – Nice report – many product types moving different directions. A few items I am looking for – Will solar panel prices start to drop as Chinese demand slows by mid year? Answer – they haven’t begun to fall yet, but no significant demand bumps have occurred to drive volume up year either. What are utilization rates of factories? Answer – the Taiwanese factories noted in this article are running 50-60%.

Electrek green energy brief: Snow on solar, CT carbon tax, mergers and acquisitions, more

Site default logo image

Connecticut talking about a $15/ton carbon tax – The word ‘direct dividend’ is used to describe a portion of the carbon tax being returned to business (30% of tax) and private people (40%). 25% of the tax will be used to invest in efficiency/infrastructure. The article tries hard to paint that a carbon tax is coming – first they point out that many states in the region are doing it, and they quote a politician saying Washington DC is ‘sending signals.’ Hrmm – 25% of a carbon tax to infrastructure/efficiency…it’s something.

Since the northeast USA got some snow yesterday – here is a short on snow and solar panels – 1. Snow slides off – without frames it slides fast – higher angles it slides fastest. 2. Snow cleans panels as well any anything cleans panels. 3. Microcracks can develop from too much weight – research is being done. 4. Light gets through the snow – so much so – that it generates electricity even when covered. 5. Type of snow will affect how snow rolls off, as well as wind. 6.* Added by me – when that tiny bit of light get through to the panels, the panels heat up – and start to melt the snow (header image from linked video). Plus these benefits from the comment section.

Solar viability at Google’s Googleplex HQ

According to the search giant, almost 4 in 5 US homes are viable for solar panels with over 90% of homes in sunny states like Florida and California being viable. But even for houses in “not so sunny states” like Maine and Minnesota, over 60% of the homes surveyed were eligible to benefit from solar panels.

That’s a huge, untapped market for solar companies like Tesla’s SolarCity subsidiary…

Exxon CEO hid climate change communications from legal probe – First off, #exxonknew and they continued to pay third parties to lie to the public about the effect of CO2 on climate change. And they know the bell will soon toll – the question is how long can they hold off the wolves of public opinion, how much more cash can be generated? That’s all it comes down to. Money.

EIA probably going to underestimate their solar development projection, again – It’s almost a joke how the EIA constantly underestimates how much solar power will be built, and this matters because it influences policy and the public. Of course, it is a bit more complicated than a batch of great scientists missing data – and the EIA has responded to these criticisms. I’ll take the path that we need not look at the EIA for solar power projections in the USA – it’s not their job and they don’t focus on it (as they say clearly in their report). That means government folk ought not to pay attention to the projections and instead maybe look at Greentech Media who seems to get pretty close every year.

A carbon dividend really can slow fossil fuel use — under these conditions – First off, I don’t like this article at all. Don’t like how they describe things – and don’t like their conclusions/parallels to other programs. The reason I grabbed the article – I think whomever is writing this document is getting a nudge to use the term ‘carbon dividend’ in a headline.

California should ignore the naysayers, and dive into wind and solar as they aim for 100% clean energy

Site default logo image

California recently put forth a resolution to consider 100% renewable electricity by 2045, paving the way for solar and wind to spread their wings as the main electricity sources in a state on the frontier of renewable energy. But Julian Specter at Greentech Media argues the choice to forego other market choices in California, to focus solely on wind and solar as electricity sources, is a bad strategy to achieve lower climate warming emissions.

I think that logic put forth by GTM is wrong. California needs to aggressively chase this path toward 100% renewable for the following reasons: one, the state is only one market among many; two, prior examples of ultra-focused groups ‘over investing’ in a technology have brought about amazing change;  three, wind and solar technology can get it done; and, finally, legislative paths can change if need be.

California can go it alone and focus on these high probabilities of victory technologies without hurting the rest of us. In fact, it probably needs to so the rest of us can benefit from their advancements.

New York state: “Utilities should be using energy storage as part of their normal course of business” – We’re seeing energy storage grabbing onto more chunks of the power grid. There is a game that occurs inside of us – we see headlines of something happening far away, we see rich thought leaders do it, we see others we know do it, we see our competition do it – each of these occurrences build up a certain confidence in ourselves. New York State is pushing because they recently bore the consequences of a hurricane combined with ocean rise, and were reminded of the need to be resilient. The reason they chose this path i particular is because others had shown it to be sound. No fluff – just your normal course of business.

$100 trillion of institutional money in the world, and less than 1 percent is invested in anything green – I’ve heard $1T/year is needed to fix the co2 issue. Globally – $287B in green investments. In the US, $200B in 2016 in a broader set of technologies. These numbers aren’t covering the exact same area – but they give you a scope of the work being done, and that we need do more work still. After we juxtapose those needs with the available capital – we should feel a bit more optimistic on the financial potential. Solar, wind and energy storage projects are able to come on piece meal and relatively quickly, meaning cash flows back to investors start sooner than later – time value of money stress is lowered and money gets deployed again. Virtuous cycle.

Electrek green energy brief: US solar capacity to triple in 5 years, $200B in clean energy in 2016, Sunrun +39%, more

Site default logo image

US Solar total solar capacity expected to triple in next five years – If we were to double every 2.5 years, solar would take over all energy on the planet in about 20 years, tripling every five years is a bit slower of a rate – but still awesome. We are still in the early stages of solar power – it might be hard to believe that with the amount of money and the headlines every day – but 70GW a year globally is not enough to change the planet – we need 500GW a year of solar and the same amount of wind to do that…but we’re getting closer.

$200B in clean energy in 2016 – Since it seems political America doesn’t care about cleaning the planet unless they make money, here’s $200B a year that will triple by 2022. And guess what we’re going to use that leverage to put a crowbar between politicians and their US tax payer paid jobs.

“Do you think you’ve dreamt too big?” “Yes, but I do not regret it.” – The way the solar was deployed is too expensive, yeah – this is true. Years ago when this guy started, we were nowhere near where we needed to be cost and technology wise to make his vision economic – but slowly that is changing.

Electrek green energy brief: Battery storage doubles, Rhode Island for 1GW, Solar panels to ¢25/W in ’17, more

California’s record breaking battery banks drive doubling of energy storage in US 2016 – And the chart seems to predict a tripling of that volume in 2017 to 1GWh. 300% growth in 2017 is going to make a lot of manufacturers step their game up. Wonder what percentage of that 1GW Tesla will be delivering? We know Samsung SDI is also big.

Rhode Island going for 1GW by 2020 – While 1GW of renewables for a lot of places isn’t that great (remember there are single projects larger than 1GW popping up these days). 1GW for a state that takes 45 minutes to drive across is something to consider – not to mention that to get to 1GW by 2020 it will involve growing almost 10x from today’s deployed volume in less than 4 years. I work in Rhode Island on a regular basis – got a sales call there today. The businesses and private people are interested – paying $0.16/kWh with healthy demand fees adds up quickly.

Solar panels at ¢25-26/W by the end of the year – If the volume of manufacturing keeps increasing, but the global demand stays flat in 2017 (expected to happen) – something will have to change. This aggressive pricing driven by the Chinese will give Indian manufacturers another year of hell. Chinese panels are ¢10/W cheaper than Indian.

Saudi Aramco selling $500B (?) in stock, investing $5B of it in solar – Groups representing $60 trillion (wow) in investment capital have pledged ‘to incorporate environmental, social and governance factors, known as ESG, into their investment decisions.’ Aramco is hoping to draw a slightly greater portion of these folks by making an investment in the largest oil company on the planet slightly solar powered. This is seperate from the countries $30-50B in solar power that is coming. $5B out of a valuation from $400B to $2T (estimates for the value of the oil company) represents 1.25% to 0.25%, respectively. Purist investors think its foolish to mix these investments, however – I’ll argue that the world is more complex than one line descriptions of what an IPO should be – and I am glad to see this, even if it is a slight manipulation of ‘clean’ to get what they want.

Solar power being requested in strategic locations to INCREASE grid stability – That’s right, none of this ‘solar power is bad for the grid’ crap – that’s 1999 talking. The utilities of the more advanced solar states in the USA – California in particular – are already mapping out where solar need be. And now, officially, Southern California Edison is ready to pay you extra if you build a plant that connects to the grid in predetermined places. Strategic solar power can lower the cost of grid upgrades – can lower voltage loss far from the factory – and with the right hardware, can offer additional services that the grid needs to keep it stable.

If we all had smart meters installed – and we all had LED lighting that was using unique features to lower the energy usage – we could be paying a $100M more than we should.

Abu Dhabi aims to close $872 million solar plant financing in April – 74¢/W is what you pay for 1.17GW in the desert. It wasn’t too long ago that solar panels themselves cost 74¢/W — actually like two years ago. I wonder if JinkoSolar is being given partial ownership in exchange for the solar panels – long term cash generation?

Utility sued by solar power users who believe net metering credits not properly applied – Taking this article, plus the lead regarding smart meters, pushes me further to think there is a need in the marketplace for better energy usage knowledge. Every item plugged the house can be better managed – and we ought be tracking usage on that level. If we’re doing that – then we’ll be able to know exactly what our electricity bills should look like every single month. Check out Sense.com for one such product.

Electrek green energy brief: Investment in solar power funds, climate science in 1859, solar 1.4% of US electricity, more

Site default logo image

Foresight targets new 250MW UK pipeline with fresh placing – In essence, the group is selling shares in a cross section of solar projects. I don’t know exactly how it pays out – but it would seem logical to get some sort of payment for the electricity being sold in a near real time basis. What is the global appetite for investing into solar funds? We know hundreds of billions. Trillions? It’d be interesting to buy enough solar power in your initial offerings that the collected energy revenue would be enough to considerably grow the solar portfolio over time, versus paying out for, say, the first five years. A 30 year investing that grows itself for the first five yeas before it starts to draw down. In the US making use of tax credits and depreciation would mean tax free electricity revenue to reinvest in new solar projects.

The basics of climate science were lain in 1859 by John Tyndall – ‘Tyndall’s most striking discoveries were the vast differences in the abilities of “perfectly colorless and invisible gases and vapours” to absorb and transmit radiant heat.’ Using the machine pictured above, Tyndall discovered that complex molecules like water vapor and carbon dioxide (plus others) were the best absorbers of heat. We knew the fundamentals of how we were going to heat our planet in 1859 – 158 years ago. Darwin published The Origin of Species that year…another ‘controversial’ idea.

Tyndall announced some of his early results on May 26, 1859. 93 days later, in Titusville, Pennsylvannia – Drake struck oil and the ‘first large-scale commercial extraction of petroleum” was underway.
