“Large battery in Brandenburg starts operations”

A 5-megawatt storage battery has started regular operations in Brandenburg, after a 1-year test run was completed successfully, PV magazine reports.

The battery is among the biggest of its kind in Europe and has the prequalification as a network stabilising facility.

The facility could substitute the balancing power provided by a 100-megawatt thermal power plant, thereby saving 20,000 tonnes of CO2 annually  , operator Upside G roup said.

Tesla Wins Massive Contract to Help Power the California Grid 


It's the latest response to a fossil-fuel disaster.


by  Tom Randall 
September 15, 2016 — 2:21 PM EDT

Tesla just won a bid to supply grid-scale power in Southern California to help prevent electricity shortages following the biggest natural gas leak in U.S. history. The Powerpacks, worth tens of millions of dollars, will be operational in record time—by the end of this year.      

Tesla Motors Inc. will supply 20 megawatts (80 megawatt-hours) of energy storage to Southern California Edison as part of a wider effort to prevent blackouts by replacing fossil-fuel electricity generation with lithium-ion batteries. Tesla's contribution is enough to power about 2,500 homes for a full day, the company said in a blog post on Thursday. But the real significance of the deal is the speed with which lithium-ion battery packs are being deployed.

"The storage is being procured in a record time frame," months instead of years, said Yayoi Sekine, a battery analyst at Bloomberg New Energy Finance. "It highlights the maturity of advanced technologies like energy storage to be contracted as a reliable resource in an emergency situation."

Here's a chart (at article link) showing the acceleration of energy-storage deployment as batteries gain popularity.

The deal fits into Tesla Chief Executive Officer Elon Musk's long-term vision of transforming Tesla from an an electric car company to a clean-energy company. That's the same motivation behind his pending deal to acquire SolarCity Corp., the rooftop solar company founded by his cousins, of which he is also chairman and the largest shareholder.

In total megawatt hours, the Tesla batteries will make up the biggest lithium-ion battery project in the world, though it will soon be surpassed by others under contract, according to data compiled by Bloomberg New Energy Finance.1increase click area A Tesla spokeswoman declined to comment on the value of the 20 megawatt deal. According to Tesla's website, a 2-megawatt Tesla battery system costs about $2.9 million, and any contracts greater than 2.5 megawatts must be negotiated directly with the company.

Last fall's natural gas leak at Aliso Canyon, near the Los Angeles neighborhood of Porter Ranch, released thousands of tons of methane before it was sealed in February. In its wake, SCE and other utilities are pursuing energy storage deals. To alleviate the risk of blackouts, regulators ordered the installation of systems to store electricity when demand is low and deploy it when usage spikes, especially during the winter heating season.

Although Sempra Energy plugged its massive gas leak in February, use of its Aliso Canyon complex, California’s biggest gas storage field, remains restricted. Grid-storage projects are now being fast-tracked and built in less than four months, compared to an average of three and a half years in previous procurements, according to data compiled by Bloomberg New Energy Finance.

In August, California regulators approved two contracts for AES Corp. to build 37 megawatts of grid-scale energy storage systems to address anticipated power shortfalls stemming from the Aliso Canyon leak. Canadian energy company AltaGas Ltd. also won a 20 megawatt (80 megawatt-hour) contract with Southern California Edison to be completed this year.

"This isn’t a Tesla-only story," Sekine said. "This is a broader energy win."

Chicago aquarium’s battery will have broader impact on the grid
     


Written By
David J. Unger
10/03/2016

Chicago’s Shedd Aquarium is known for its work to exhibit and conserve the complexity of Earth’s aquatic ecosystems. But in the coming weeks, the civic institution will find itself an extension of another complex – albeit very manmade – system: the 21st-Century electric grid.

In June, Shedd installed a 60,000-pound, $2 million battery as part of the aquarium’s plan to cut energy consumption in half by 2020. Like all energy-storage systems, Shedd’s battery will provide valuable backup power and help meet peak demand for the aquarium.

But the 1 megawatt, lithium-ion system will also play a broader role in the way electricity supply and demand is balanced across the region. Once its battery comes online, Shedd will be able to sell stored power into electricity markets run by PJM Interconnection, the regional transmission organization that manages electricity production and flow across 13 states and the District of Columbia.

The battery was funded by a grant from the Illinois Department of Commerce & Economic Opportunity and installed by Schneider Electric. Bob Wengel, vice president of facilities at Shedd, says the battery should be ready for operation by the end of October.

At that point, Shedd will essentially straddle the divide between power consumer and power producer, a divide that has long defined the existing power grid.

“If you go back 30 years, the grid was a one-way street,” Wengel told Midwest Energy News during a recent visit to tour the aquarium’s energy system on a blustery, wet day. The rise of wind and solar power help reduce the strain on natural resources, but they also make traffic on the grid more complicated.

Grid operators like PJM have to make sure power flows are consistent and stable despite the rise in variable energy sources like wind and sun. Typically, that spare capacity is ensured by keeping fossil fuel plants running in case of a sudden change in supply or demand.
Quote

Batteries, like the one being installed at Shedd, offer a cleaner alternative for managing the grid.

“If you had enough batteries out doing this … you could shut down those plants,” Wengel said. “Now think of the natural resources you save   .”


‘A huge relationship’ 


Of course, Shedd is not the first to embrace the title of “prosumer,” as producer-consumers are sometimes called in the energy industry. Nor will it be the last. Most households with rooftop solar are themselves extensions of the grid, both producing power and demanding it. Analysts expect the grid of tomorrow to consist largely of these kinds of distributed networks of prosumers sending energy back and forth to one another.


But for Shedd – home to 32,000 aquatic animals – the impetus for helping to usher in a smarter, more decentralized grid hits particularly close to home.

Quote
“If we could save the CO2 emissions from power plants, and we can save the water resources, we’re starting to protect the habitat that our animals live in,” Wengel said. “There’s a huge relationship there for us.”

In 2013, Shedd partnered with the City of Chicago, the Illinois Science and Technology Coalition and other groups to put together a Master Energy Roadmap that would guide the aquarium toward reducing its energy use by nearly 10 million kilowatt-hours (kWh) per year. The average Illinois household consumes about 8,940 kWh per year, according to the U.S. Energy Information Administration. That means Shedd would save enough energy each year to power around 1,100 Illinois households.

“The collaboration is an exceptional example of how organizations across public and private sectors can work together to find innovative ways to make our civic institutions use energy smarter, cleaner and more efficiently,” Chicago Mayor Rahm Emanuel said in a press release at the time.

Since then, Shedd has installed 913 solar panels with a capacity of 265 kilowatts on the roof of its Abbott Oceanarium and some 1,000 efficient LED lights throughout its facility on Chicago’s lakefront. The battery aims to complement the existing energy system by offering backup power for critical systems and an additional source of revenue in the form of selling power back onto the grid. Later on, it may be used for grid-scale demand response or to help meet the aquarium’s peak demand locally, Wengel said.

The battery and solar systems are relatively small in comparison to the aquarium’s overall energy use. The solar panels generate between 300,000 to 400,000 kWh a year. That’s a drop in the bucket compared to the 1.2 million to 1.6 million kWh Shedd consumes in just an average month.

But the southwest facing panels make up for limited capacity with good timing. By catching the late-afternoon sun, the panels are able to provide an extra boost when it is needed most – between 3 p.m. and 6 p.m. when energy demand is highest.


Education mission

Behind the scenes at Shedd, in a small windowless room out of sight from the stingrays, penguins, turtles and other creatures, is the brain behind the aquarium’s advanced energy system. Seven computer monitors display real-time data about the building’s overall energy consumption, the status of various pumps, water heaters and other equipment, local weather conditions and the flow of power from the rooftop solar panels.

One screen displays a graph representing the target energy consumption levels throughout the day. The goal for the operator is to try to adjust various equipment to keep overall energy consumption at or below the target.

Quote
In the first month of using the system, Shedd was able to reduce its consumption by 50,000 kWh  , Wengel said.

It’s an elaborate setup for an institution whose primary focus is water, not energy. But the two are deeply linked, as power plants require water for cooling and large amounts of energy are required to pump, treat and heat water for consumers.

In its pursuit of sustainability, it would have been easier for Shedd to purchase renewable energy credits that offset carbon-heavy generation from fossil fuel plants. But instead the institution spent years researching, planning, partnering and ultimately building its own unique energy system.

For Wengel, doing the legwork, the “soul searching” and the hosting of a physical system onsite is core to Shedd’s educational mission.

“We’re going to educate people about the battery,” Wengel said of the system. “We’re also going to relate it in a way that [says], ‘Someday you’re going to have a battery in your house.’”


Independent reporting on Illinois smart grid issues is made possible by a grant from the Illinois Science & Energy Innovation Foundation.

Tesla Unveils World's Largest Battery Storage Plant to Reduce Reliance on Fossil Fuels   

SNIPPET:

In an effort to reduce the reliance on fossil fuels, Tesla and Southern California Edison have unveiled a massive battery storage facility at the utility's Mira Loma substation in Ontario, California.

The project—which is being described as the largest lithium-ion battery storage project in the world—consists of 396 stacks of Tesla Powerpack units spread across 1.5 acres. The batteries can store up to 80 megawatt hours, or enough energy to power 15,000 homes for four hours.

"This project is part of our vision at Southern California Edison to take advantage of the wind and the sun, and operate a flexible grid that delivers clean energy to power our homes, our businesses and our vehicles," Kevin Payne, CEO of Southern California Edison, said at a ribbon-cutting event Monday.

"Standing here today among these Tesla Powerpacks is a great reminder of how fast technology is changing the electric power industry and the opportunities that will come with it."

While the project officially switched online on Monday it began operating in December.

"We are very excited to bring this site online," said Tesla's chief technical officer JB Straubel. "Storage is quite a new thing … and this is a different breed of battery. This is the tip of the iceberg of how much storage we'll see on the grid."


The batteries charge up when there is more renewable energy than demand, ultimately allowing customers to use clean energy during peak hours.

As the New York Times explained, California has a need for batteries to store surplus renewable energy:

"California is on track to have an overabundance of energy during the day, when its many solar panels are producing energy, but that supply drops sharply as the sun sets, precisely when demand rises, with residents heading home to use appliances and, increasingly, to charge cars.

"The state's aging nuclear plants have been closed or are being phased out, putting even more pressure on utilities to find other ways to feed the grid. Storage is a natural solution, utility executives say, helping to smooth variations in the power flow from rooftop customers and when solar falls off and conventional plants have not yet filled the gap."

Tesla CEO Elon Musk was not at the ribbon-cutting ceremony but he retweeted a company tweet in support of the project. In the clip below, Tesla touts that its new facility, which only took 94 days to install, reduces the reliance on gas peaker plants, prevents electricity shortages, provides secure energy and reduces greenhouse gases:

3 More Gigafactories Coming Soon to 'Change the Way the World Uses Energy'    

Lorraine Chow


At the grand opening of Tesla's enormous Gigafactory in July, CEO Elon Musk said he wants to build Gigafactories on several continents. He told BBC he wanted a factory "in Europe, in India, in China ... ultimately, wherever there is a huge amount of demand for the end product."

Well, it looks like Musk's factory-building plans are well underway.

The company said in its fourth-quarter investor letter on Wednesday that it is considering building up to five Gigafactories:o  ;D

The letter states:

"Installation of Model 3 manufacturing equipment is underway in Fremont and at Gigafactory 1, where in January, we began production of battery cells for energy storage products, which have the same form-factor as the cells that will be used in Model 3. Later this year, we expect to finalize locations for Gigafactories 3, 4 and possibly 5 (Gigafactory 2 is the Tesla solar plant in New York)."

Tesla officially flicked on Gigafactory 1's switch in January. The factory produces lithium-ion battery cells for Tesla's suite of battery storage products, the Powerwall 2 and Powerpack 2, as well as the company's mass-market electric car, the Model 3.

Gigafactory 1 is currently being built in phases so that the company and its partners can manufacture products while the building continues to expand. Construction is expected for completion by 2018, at which point the plant could claim the title of world's largest building by footprint.

The facility will also be astoundingly clean and energy efficient, as it will be powered 100 percent by renewables such as solar, wind, geothermal and will feature energy-storage technology.

The company also plans for the building to achieve net zero energy. Tesla co-founder and chief technical officer JB Straubel once explained why Tesla wanted Gigafactory operations to be completely carbon neutral:

"The Gigafactory is maybe the best example we can talk about with this. You know, from the get-go, from the first concept of this factory, we wanted to make it a net-zero facility. So, you know, the most visible thing we are doing is covering the entire site with solar power. The whole roof of the Gigafactory was designed from the beginning with solar in mind. We kept all of the mechanical equipment off the roof. We didn't put extra, sorta, penetrations through the roof that we didn't need to and it's a very, very clean surface that we can completely cover in solar. But that's not enough solar, though. So we have also gone to the surrounding hillsides that we can't use for other functions and we're adding solar to those."

According to Straubel, the Gigafactory isn't even hooked up to any natural gas pipelines:
 

Quote
"The other interesting thing is we wanted to manage the emissions from the Gigafactory. Solar power can do some of that, but we took kind of a radical move in the beginning and said we are not going to burn any fossil fuels in the factory. You know, zero emissions. We are going to build a zero-emissions factory—just like the car. So, instead of kind of fighting this battle in hindsight, we just said we are not even going to have a natural gas pipeline coming to the factory, so we didn't even build it. And it kind of forced the issue. When you don't have natural gas, you know, none of the engineers can say, 'Oh, but it will be more efficient, let me use just a little bit.' Sorry, we don't even have it."

In December, Tesla and Panasonic launched operations at its Buffalo, New York plant, now dubbed Gigafactory 2. The factory manufactures high-efficiency photovoltaic cells and modules for solar panels and solar glass tiles for Tesla's highly anticipated solar roof.

Tesla's factories are all part of the company's mission to accelerate the world's transition to sustainable energy. 

In last year's climate change documentary Before The Flood, Musk takes Leonardo DiCaprio on a tour of Tesla's massive Gigafactory in Nevada. During their chat, the Tesla CEO tells the actor and famed environmentalist that it would only take 100 Gigafactories to transition "the whole world" to sustainable energy.

With at least five Gigafactories in the books, looks like Musk's plans are slowly becoming reality. For what it's worth, even DiCaprio said building one-hundred Gigafactories "sounds manageable."

Agelbert NOTE: Fossil Fuel Industry reaction to all the above:   

Expect the Fossil Fuel Industry TOOLS from Trump (Tillerson, Pruitt et al) to publish "concerns" (for our own good OF COURSE  ) over the "potential for the dangerous battery pollution"  ;) from the Gigafactories  to cause "harm to human health and the environment".

Eneco and Mitsubishi Corporation construct largest battery in Europe 

JARDELUND, 06 April 2017

bess

Eneco and Mitsubishi Corporation (MC) are going to construct, under the name EnspireME, the largest battery system in Europe. This battery system will be located in Germany and enables the companies to supply sustainable reserve capacity to the European electricity grid. Both parties will also start a pilot project involving the storage of locally produced surplus wind energy.

In connection with the ‘Energiewende’, Germany is a frontrunner in increasing the sustainability of its energy supply. As a result, an increasing number of wind turbines and solar panels are taking over the production of electricity from existing fossil fuel power plants. However, these plants continue to play a role in the form of supplying reserve capacity that is needed to balance the power grid. The battery system will be able to take over the role of primary reserve provider and, thus, forms a sustainable alternative for the backup supplied by coal and gas fired power plants.

Jardelund

Eneco and MC will start the construction of the battery system in the Summer. The battery will be located next to a substation in the municipality of Jardelund in Schleswig-Holstein, close to the border with Denmark. Schleswig-Holstein is one of the leading federal states contributing strongly towards a successful ‘Energiewende’ in Germany. It is the place where electricity generated by large wind farms is collected and transmitted to other parts of Germany.The proximity of the substation has the advantage that the battery can play a role in reducing the regular loss of energy at these stations. Initially, the battery will be used for the primary reserve market, where the German transmission network operators purchase the reserve capacity they require to guarantee the 50 Hertz frequency on the grid.

[Pilot project

With the support of the German federal state of Schleswig-Holstein, Eneco and MC will start a pilot project that will involve the connection of nearby wind farms to the battery system. If there is surplus capacity or an overload on the grid, these wind farms will be able to temporarily supply their electricity output to the battery system. This will not only reduce the load on the grid, but also has a financial advantage as the owners of the wind farms will be able to offer the stored electricity to the market at a more favourable moment.

Energy storage technology

The battery is a Lithium-Ion system of 48 MW and a capacity of over 50 MWh, which corresponds to the average daily energy consumption of over 5.300 German households. The battery system, including the power conversion system and controls, will be supplied and integrated by NEC Energy Solutions, a large energy storage system integrator. It is expected that the battery system will be put into operation at the end of 2017.

Hiroshi Sakuma, Group Chief Executive Officer, Mitsubishi Corporation: 'We have been strengthening our activity in the renewable energy field in order to contribute to a low-carbon society. We believe that energy storage will become a key factor, given the circumstance that energy volatility is expanding as the result of the rapid increase of renewable energy. This project is a significant step forward to the realisation of the sustainable society.'

Kees-Jan Rameau, Chief Strategic Growth Officer Eneco Group: 'Although, fortunately, the share of sustainable energy is increasing rapidly, it does pose a challenge for the energy grid. In our view, the solution to this is twofold: smart matching of supply and demand and a combination of small-scale and large-scale energy storage. Last year, we initiated the creation of a network of home batteries for consumers. In collaboration with Mitsubishi Corporation, we are now also making significant progress in the area of large-scale sustainable storage. Germany is a frontrunner in green development and, as such, ideal for gaining experience. This step will also provide valuable knowledge that can be applied on the Dutch market.'

Those bubbles on the seaweed fronds are oxygen produced by these amazing plants.

Quote
.. seaweed and other algae takes up 90 percent of all plant life on Earth 

Seaweed Could Revolutionize How We Power Our Devices
 

The answer to powering our devices might have been hiding in our sushi all along  ;D. An international team of researchers has used seaweed to create a material that can enhance the performance of superconductors, lithium-ion batteries and fuel cells.

--------------------------------------------------------------------------------

The team, from the U.S., the UK, China and Belgium, came up with the idea to mimic Murray's Law, which is a natural process within the structure of a plant's pores that pumps water or air throughout the plant to provide it energy. With Murray's law, the larger the pore, the less energy expended because the pressure is reduced, but it takes different variations in size to create a balancing act across the body of the plant and maximize energy potential. In seaweed's case, the plant has the perfect pore variation for regulating energy in real world applications.

"The introduction of the concept of Murray's Law to industrial processes could revolutionize the design of reactors with highly enhanced efficiency, minimum energy, time and raw material consumption for a sustainable future," said Bao-Lian Su, professor at the University of Cambridge and co-author of the research.

The scientists made the "Murray material" by embedding an extract of the seaweed into multiple layers of nano-fibers of zinc oxide, which created a hierarchy in the size of the pores. They believe the material can be used on rechargeable batteries, high performance gas sensing technology or even to decompose inorganic material in the oceans.

Seaweed is a fast growing algae that grows in abundance in coastal areas. It is estimated that seaweed and other algae takes up 90 percent of all plant life on Earth, making it a very sustainable plant for energy purposes. The team believes they could safely utilize 20,000 tons of the seaweed extract per year.

The Murray material could improve capacity by 25 times compared to the current graphite-based technology being used in lithium-ion batteries. The pores in the material also allow for a smoother charge/discharge process, improving stability and extending the life of batteries or fuel cells.

"Large scale manufacturability of this porous material is possible," said co-author Tawfique Hasan, also at Cambridge. "Making it an exciting, enabling technology, with potential impact across many applications."

Agelbert NOTE: The above research, particularly in regard to pore size and flow rates, is part of the REAL WORLD of thermodynamics that the fossil fuel industry pretends "does no exist"   in their "heat, beat and treat" brute force approach to energy production. Combusting hydrocarbons is one of the most ruinously polluting ways to produce energy mankind has ever come up with. But since the polluters have been able to dump all the SOCIAL COSTS OF CARBON onto we-the-people while they use their ill gotten profits to CORRUPT our politicians, they just can't let go of their love affair with conscience free polluting for short term profit.     

There are MANY solutions to our energy problems that continue to be willfully ignored by our government simply because the fossil fuel industry DOESN'T WANT THEM IMPLEMENTED. No, sports fans, it NEVER had absolutely anything to do with ERoEI, energy efficiency or "cheap" energy sources. It's ALWAYS been about controlling the spigot of energy available to the average person so that these fascist, government corrupting polluters can retain political totalitarian power.

Below, please find, just one of the MANY CLEAN ENERGY solutions to the polluting energy onslaught degrading our biosphere.


The idea is that multiple methods will ensure species survival. It's called putting ONLY A SMALL AMOUNT of polluting fossil fuel eggs in your energy production basket. AND, those hydrocarbons must be obtained cleanly, not through dirty drilling or mining. Only IDIOTS that defend fossil fuels as a "cheap" and "energy dense" energy source are too STUPID and GREEDY to understand that. Have a nice day.

Safety grid for power

Power grid operator Tennet and household power storage provider Sonnen plan to use a network of small-scale batteries to help reduce costs caused by grid bottlenecks between Germany’s windy North and the power-hungry South, reports Michael Bauchmüller in Süddeutsche Zeitung. “We want to integrate renewable power in the best possible way,” Tennet board chair Urban Keussen told the newspaper.
Quote
“We can manage that not only with copper, but also with intelligence.”
Sonnen managing director Philipp Schröder said that in a first stage, 6,000 batteries would be used to optimise the power grid. Households making their batteries available for the project, which will use blockchain encryption technology, will receive free power, according to the article. Keussen told newspaper Die Welt the use of blockchain was “the first step into a new energy world.”

Power grid revolution

The use of batteries to level out intermittent solar and wind generation in the Tennet and Sonnen project shows that “the Energiewende is making progress,” writes Andreas Mihm in Frankfurter Allgemeine Zeitung. “New offshore wind parks have been approved recently without a cent of eco power support, and now there is evidence for a revolution in the German power grid. For the first time, a grid operator will get access to thousands of small decentralised power storages all over Germany.

Transmission highway SuedLink enters next stage

The preparation procedure for building Germany’s high-voltage transmission highway SuedLink has entered a crucial stage, news agency dpa reports in an article carried by Welt Online. Following submission of the sectoral planning application for SuedLink’s last segment in the southern federal state of Baden-Württemberg, German federal grid agency BNetzA can now start the formal approval procedure for the 800-kilometre-long power line meant to transfer electricity from Germany’s windy north to industrial centres in the south, the article says.
 
In a separate article on Welt Online, dpa reports that about 3,000 people forming a human chain in the central German state of Thuringia protested against SuedLink’s construction. The transmission highway made the federal state the “pack animal” of German energy policy, protesters lamented according to the article.

US Energy Storage Caucus Launched to Educate Congress
   

May 9, 2017  By Renewable Energy World Editors        energy storage
 
U.S. Reps. Chris Collins (R-N.Y.) :o  ;D and Mark Takano (D-Calif.) yesterday launched the Advanced Energy Storage Caucus in Congress to educate Members of Congress regarding the benefits of storage to the U.S. electric system and investigate ways to accelerate job growth and investment in U.S. advanced energy storage industries.

The Energy Storage Association (ESA) said that Collins and Takano were joined for the launch by executives from leading utilities, developers, and manufacturers of storage technologies, including AES Energy Storage, S&C Electric, Stem Inc., and National Grid.

In addition, the caucus will periodically brief members of Congress on how energy storage is reshaping the way electricity is generated, distributed, and consumed, and how policy can remove impediments to greater use of battery storage.

"We need bipartisan solutions to help address our aging energy infrastructure," Collins said in a statement. “Energy storage technology will grow our economy and make sure American businesses can compete around the globe.”

New Virginia Law Expands Solar Energy Development Authority to Include Energy Storage
   
May 9, 2017

By Renewable Energy World Editors     solar
 
Virginia Gov. Terry McAuliffe yesterday signed a bill authorizing the expansion of the state’s Solar Energy Development Authority to include energy storage.

The legislation is part of a series of bills signed by McAuliffe that promote wind, solar and energy storage technologies.

SB 1258, introduced by Sen. Adam Ebbin, expands the purpose of the new Solar Energy and Battery Storage Development Authority to include positioning the state as a leader in research, development, commercialization, manufacturing, and deployment of energy storage technology.

The powers of the authority are expanded to include

•Promoting collaborative efforts among Virginia's public and private institutions of higher education in research, development, and commercialization efforts related to energy storage,

•Monitoring relevant developments nationally and globally,

•Identifying and working with the state’s industries and nonprofit partners.

In addition, the measure expands the size of the authority 11 to 15 members.

“Today, I am honored to sign these bills into law, furthering the great work we’re doing to support and promote the clean energy sector across the Commonwealth,” McAuliffe said at the bill signing ceremony, according to the governor’s office. “It is clear that Virginia is moving in the right direction, especially with the recent announcement of record growth in our solar industry, but there is still work to do.  Together, with our partners in the General Assembly and the private sector, I will continue to implement policies that bolster the entire clean energy industry in the Commonwealth.”
 
The governor’s office said that other bills pertaining to renewables that were signed by McAuliffe yesterday include:

•SB 1393, which creates a path for the development of community solar programs in the service territories of Appalachian Power Company (ApCo), Dominion, and the Electric Cooperatives.  Each utility will develop its own territory-specific program that allows citizens and businesses the ability to “subscribe” to receive electricity generated by a small centrally-located solar generation system.

•SB 1394 and HB 2303, which are identical bills, create a Small Agricultural Generators Program — a new framework for the generation of renewable energy at agricultural facilities and how that energy can be sold to utilities.

•SB 1395 increases the allowable maximum size of renewable projects to be eligible to be permitted through the state’s Permit by Rule (PBR) process from 100 MW to 125 MW.  These projects are exempt from environmental review and permitting by the State Corporation Commission. SB 1395 also exempts projects that are being built for use by a single customer of a utility from having to apply for and receive a Certificate of Public Convenience and Necessity from the SCC.

California: 'We Are Just Getting Started'   

   

May 11, 2017

By Jason Deign      energy storage

If you thought California’s lead as an energy storage market might fade in the face of upstarts such as Australia or Germany, then think again. Recent moves might see new gigawatts of capacity being installed across the state by 2020.

 The most significant development was the recent reopening of California’s Self-Generation Incentive Program (SGIP) with more than US$448m in funding dedicated to energy storage.

The cash, 79 percent of an almost $567m funding package available through 2019, is expected to create a surge in behind-the-meter energy storage deployments across the state.

Most of the storage budget is aimed at what the California Public Utilities Commission (CPUC) calls ‘large-scale storage,’ or systems of more than 10 kW. But 13 percent, or just over $57m, will be for residential installations.

“The incentive level for energy storage systems larger than 10 kW that do not take the investment tax credit (ITC) and all residential systems 10 kW and smaller will be set at 50 cents/watt-hour,” says the CPUC on its website.

Projects That Are Larger than 10 kW

“Projects that are larger than 10 kW and take the ITC will have a lower initial incentive rate of 36 cents/watt-hour.
 
“We expect that demand will exceed the amount of funding for incentives at that level very quickly, and we therefore expect incentive levels to decrease by 10 cents/watt-hour shortly after SGIP reopens.”

The new SGIP will act in addition to a provision for behind-the-meter storage that already exists within the Assembly Bill 2514 (AB 2514) mandate that has powered deployments in California so far.

The AB 2514 provision is for 200 MW of capacity, to be procured by 2020 and installed by 2024.

But the SGIP, which had its budget doubled under legislation agreed last year, “is going to blow it out of the water,” said Janice Lin, founder and executive director of the California Energy Storage Alliance (CESA).

Instrumental In Getting the SGIP to Focus on Storage

CESA was instrumental in getting the CPUC to focus the SGIP on storage, she told Energy Storage Report. Originally the program had been solely dedicated to demand response, she said.

Behind-the-meter deployments are also being boosted in California by AB 2868. This last year directed the CPUC to get the state’s three largest electrical utilities to “accelerate widespread deployment of distributed energy storage.”

In practice this will add up to 500 MW more of capacity to the system, up to 25 percent of which could be behind the meter. “We’re waiting for those utility applications,” Lin said.

On top of that, AB 2514, which is a biennial procurement program, is set to continue and is expected to mandate further utility deployments in future. But it doesn’t stop there.

This legislative session has seen no fewer than three bills emerge in the last fortnight that could each add significant further energy storage capacity to the California electricity system.

Procuring 120 MW of Energy Storage Capacity

One is a Senate Bill, SB 801, which requires the Los Angeles Department of Water and Power and Southern California Edison to procure 100 MW and 20 MW, respectively, of energy storage capacity.

The procurement has been put forward on an emergency basis to reduce the impact of the Aliso Canyon natural gas storage failure.

Finally, two other bills, SB 338 and AB 1405, aim to address California’s clean peak energy problem, commonly known as the duck curve. “The neck of the duck is the most challenging portion of our net load,” explained Lin.

And it’s getting worse. This month the California Independent System Operator (CAISO) “is expected to release a new animal,” she said. “What I’ve heard from CAISO is the ramp of the new duck is shocking. The neck is huge.”

CAISO now sees storage as a key tool for dealing with challenges such as the duck curve and Aliso Canyon, she said.

If Clean Peak Energy Bills Are Implemented

If the clean peak energy bills are implemented it is unclear how much extra energy storage capacity they might add since other measures, such as demand response, might form part of any eventual package.

However, CESA roughly calculates that it could amount to “hundreds of megawatts of storage,” said Lin. “The fundamental underlying trends are very solid for storage.

“Storage is a very helpful enabler to more and more clean energy in our mix,” she said. “There is a lot going on in California right now. While California has been trailblazing, in some ways we are just getting started.”

Solid State Batteries For Electric Cars: A New Breakthrough By The Father of the Lithium-Ion Battery


Published on Mar 1, 2017

At 94 years old, Professor John Goodenough (the co-inventor of the modern lithium-ion battery) from the Cockrell School of Engineering at the University of Texas at Austin and his colleague Maria Helena Braga have announced a brand-new solid state battery that could seriously change the way we think about electric vehicle battery packs.

Here's why we think you should pay attention to this news -- and what this new breakthrough could mean for future electric cars.

Vehicle-To-Grid Discharge, Even At Constant Power, Is Detrimental To EV Battery Performance, Study Finds  :(

May 16th, 2017 by James Ayre

SNIPPET:

There have long been critics of the idea of widespread use of electric vehicle (EV) vehicle-to-grid (V2G) technologies for a variety of reasons, but largely in relation to the potential damage done to EV batteries, and thus reduced battery lifespan.

New research from the Hawaii Natural Energy Institute at the University of Hawaii at Manoa seems to clearly support this assertion — the extra cycling that accompanies use of an EV battery for grid balancing, even when at constant power, reduces EV battery cell performance significantly.

To be more specific, the use of an EV with V2G tech could reduce the working lifespan of an EV battery pack to under 5 years time, according to the new work.  :(  :P

The researchers note, though, that simply delaying the charging of EVs as a means of balancing the grid would have only a “negligible” effect on EV batteries, and could thus represent a better option. However, this could prove to not be the case in environments warmer than “room temperature.”

V2G Battery Degradation


https://cleantechnica.com/2017/05/16/vehicle-grid-discharge-even-constant-power-detrimental-ev-battery-performance-study-finds/

Agelbert COMMENT: Well, provided this is true, EV car manufacturers should use common sense and join with electric Utilities to offer EV car buyers a 10 year guarantee, WITHOUT ANY ADDED CHARGES, for replacing the used battery pack with a new one. I make the caveat about "no added charges" because the fun and games on the average lead acid battery "guarantee" is, and always was, a rip off.

Avoiding peaking costs is well worth the 10 year battery pack guarantee. In fact, if we had a sane government, they would REMOVE all the fossil fuel "subsidies" and, instead provide EV battery pack 10 year guarantee subsidies as a matter of National Security grid stability.

But common sense and logic in regard to renewable energy is rather difficult for the United Petro-States of America.



Fossil fueler shows up with the old "not ready for prime time" baloney disguised as prudent advice:
wattleberry 

A useful warning to users of today's batteries but of limited relevance to their successors which, if anything, will be encouraged by the disclosure of another flaw awaiting correction in a key component of a product which is still at a very early stage of evolution.

agelbert > wattleberry  

Like what, the tendrils that grow and short them? We know about that. The battery development is quite mature, thank you very much. It's the fossil fuel polluting machine called an internal combustion engine that never got past the profit over people and planet stage. Gas stations will soon go the way of the dodo bird too.

The only issue with batteries of any significance that needs improvement is rapid replacement technology. We NOW have access to electricity in FAR more places than we have access to gasoline. All we need is a small "spare" battery pack that can take us home or too a quick pack replacement location nearby if our main battery pack fails.


eveee 

 
This discussion needs more clarity. People are defining whats better in odd ways. How do we define it? By how much the EV owner saves in retail electricity costs vs how much the value of the car is reduced by battery degeneration?

I tend to feel V2G doesn't make sense, because a car is not just a battery. However, when the battery is used more, the value of the car reduces.

If you want V2G, get a PowerWall instead. Then you are only reducing the value of the PowerWall, not the car.

A PowerWall is 6500. A Model S is > 65000. 10x.

Now on the other hand, we are only looking at one storage scenario, load shifting.

Already, California is starting a demand response program that pays users not to use electricity during peaks and allow the utility to dial back demand when it needs to.

That is an area for an EV owner to benefit by allowing charging to be controlled or timed to miss expensive peak demand times. That makes total sense.

Listen Up: What Home Owners Need To Know About Battery Storage Systems 
 

May 22, 2017

Since the sun does not shine at night we need a way to store daytime-generated solar energy. Net metering is an elegant and 100% efficient way to shift excess solar power, but that system will not work at high solar penetration levels. Never mind the fact that utilities are loath to allow their customers to generate electricity for less than it costs them to deliver this power.

As a result, battery storage is on the minds of almost all new solar customers. Storage technology, incentives, favorable electric rates and control software are all evolving rapidly. There are currently about a dozen companies with battery storage systems designed for use with rooftop solar. Like peanut butter and chocolate, many solar companies are starting to offer battery storage systems along with their solar systems.

My advice is to proceed with caution. Even though off-grid battery storage systems have been available for years, we are at the very early stages of grid-tied solar combined with battery storage. From a hardware standpoint, battery storage costs are plummeting, and new inverters/charge controllers are being developed. Perhaps more importantly, software that will efficiently interact with solar, batteries, the grid and your home energy consumption still has limited functionality. For more about the practicalities of home battery storage, Listen Up to this week’s Energy Show on Renewable Energy World.

About Your Host

Barry Cinnamon is a long-time advocate of renewable energy and is a widely recognized solar power expert. In 2001 he founded Akeena Solar — which grew to become the largest national residential solar installer by the middle of the last decade with over 10,000 rooftop customers coast to coast. He partnered with Westinghouse to create Westinghouse Solar in 2010, and sold the company in 2012.

His pioneering work on reducing costs of rooftop solar power systems include Andalay, the first solar panel with integrated racking, grounding and wiring; the first UL listed AC solar panel; and the first fully “plug and play” AC solar panel. His current efforts are focused on reducing the soft costs for solar power systems, which cause system prices in the U.S. to be double those of Germany.

Although Barry may be known for his outspoken work in the solar industry, he has hands-on experience with a wide range of energy saving technologies.  He's been doing residential energy audits since the punch card days, developed one of the first ground-source heat pumps in the early ‘80s, and always abides by the Laws of Thermodynamics.  ;D
