FacebookTwitterLinkedInEmailPrint分享S&P Global Market Intelligence ($):The solar energy industry has achieved its long-time quest to become cost-competitive with conventional power across wide swaths of the United States. Now it is on to a new mission: saving that energy for later.Large-scale solar power plants coupled with energy storage systems are multiplying in the U.S., as developers and grid operators seek to smooth the variable output of solar plants by storing the electricity they produce for peak power demand in the evening. At least 51 such hybrid systems 1 MW and larger are online or planned, according to S&P Global Market Intelligence data. Operational systems total 783 MW of solar capacity tied to 492 MW of storage for various periods of time, while planned projects account for 3,228 MW of solar integrated with 2,888 MW of storage.Many of these solar-plus-storage projects are concentrated in the Southwest. Hawaii and the Northeast also have multiple projects planned or underway. Beyond known projects with identifiable developers, many more solar-plus-storage power plants are earlier in the development process. Grid operator interconnection queues and recent responses to utility requests for proposals show several thousand megawatts of additional potential.In response to Xcel Energy Inc.’s recent request for proposals, for instance, developers pitched 57 projects in Colorado for more than 10,000 MW of battery-backed photovoltaics. The California ISO’s generator interconnection queue, as of May 24, showed 16 projects coupling 3,340 MW of solar PV with 2,532 MW of batteries. Another 14 solar-plus-storage projects with a combined maximum output of more than 5,000 MW were exploring interconnection in Arizona Public Service Co.’s territory, as of April 4. Additional large-scale battery-backed solar projects are under study in the ISO New England, New Mexico and PJM Interconnection.“I see a future with more battery and solar combinations,” Jeff Burke, director of resource planning at APS, said in an interview.On new energy frontier, solar-plus-storage plants proliferate New solar plants equipped with electricity-storage capacity are proliferating across the U.S.
FacebookTwitterLinkedInEmailPrint分享PV Magazine:Tunisia’s Ministry for Energy, Mines and Renewable Energy has received five bids for the 500 MW solar tender it launched in November.Mehdi Majoul, an advisor to the ministry, wrote on his LinkedIn social media account that the bids, submitted by unspecified leading international solar companies, all offered record low energy prices for the Tunisian market, according to the tender’s preliminary results.Majoul added, the lowest bid – DT71.800/kWh ($0.0244) – was for a 200 MW project in the province of Tataouine. Two 50 MW projects, in the provinces of Sidi Bouzid and Tozeur, attracted offers of DT79.300/kWh ($0.027), according to the advisor, and the two remaining 100 MW projects – in the provinces of Gafsa and Kairouan – prompted bids of DT79.900/kWh ($0.0272) and DT84.100/kWh ($0.0286), respectively.“Notably, the tariff tendered by the company Scatec Solar for [the] Tataouine project, namely $0.0244 per kilowatt hour, is the lowest bid ever recorded in Africa and is among the lowest in the world,” wrote Majoul. “The prices proposed under this tender will help bring down the cost of production of electricity nationwide and reduce the bill for energy subsidies in addition to lowering national imports of natural gas by 5%. These projects will start operating from 2021.”The Tunisian government had pre-qualified 16 developers for the tender. Among them were European energy giants Enel, Engie, Total and EDF – the latter in a consortium with UAE-based Masdar and Japan’s Mitsui. Other bidders included Canadian Solar; Spanish developers Acciona and Fotowatio; French concerns GreenYellow, Akuo and Voltalia; Norway’s Scatec; Saudi power company ACWA; and China’s TBEA.More: Lowest bid in Tunisia’s 500 MW solar tender comes in at $0.0244 Scatec Solar submits $24/MWh bid for Tunisia solar project, a record low in Africa
California’s PG&E seeks approval for 423MW/1.7GWh of new battery storage projects FacebookTwitterLinkedInEmailPrint分享Greentech Media:Pacific Gas & Electric has asked California regulators to approve seven battery projects totaling 423 megawatts, or nearly 1.7 gigawatt-hours of energy storage capacity, to meet its share of a statewide procurement that must be brought online by late next year to assure statewide grid stability.PG&E’s 2020 System Reliability Request for Offers, filed Monday with the California Public Utilities Commission, represents a huge new addition to the utility’s battery fleet to meet the state’s resource adequacy needs starting in 2021. It’s the second major procurement from a California utility designed to comply with the CPUC’s order for 3.3 gigawatts of carbon-free resources to help meet grid reliability needs that will arise when four natural-gas-fired power plants retire next year to reduce their environmental harm to coastal waters.PG&E’s portfolio of new battery projects isn’t the biggest one meant to make up for those power plants, whose retirement has already been delayed by a year to allow clean energy replacement resources to be brought online. Earlier this month, utility Southern California Edison announced 770 megawatts, or nearly 3 gigawatt-hours, of storage from seven winning bids, most of them connected to existing solar farms. SCE has the largest share of procurement since it faces the more severe potential grid disruptions from closing the power plants.But PG&E’s new proposal does represent a major boost to a battery fleet that’s already set to be the largest in the world. PG&E’s major projects include a 300-megawatt/1,200-megawatt-hour project by Vistra Energy and a 182.5-megawatt/730-megawatt-hour project from Tesla being built near a natural-gas plant in the Monterey County community of Moss Landing.PG&E is now adding another 100 megawatts/400 megawatt-hours of battery plant from Vistra to be part of its new resource adequacy portfolio in the transmission-constrained South Bay/Moss Landing sub-area. It’s also adding three 50-megawatt/200-megawatt-hour systems to the existing 50-megawatt Diablo Energy Storage project being built by LS Power in Contra Costa County.PG&E’s new round of contracts, which must still be approved by the CPUC, is the third major storage deal to be announced just this month, including SCE’s projects and another nearly 3-gigawatt-hour procurement announced by Hawaiian Electric last week.[Jeff St. John]More: Vistra, LS Power top winners in PG&E’s 420MW storage procurement
Samsung pledges to quit coal construction, but not before building Vung Ang 2 plant FacebookTwitterLinkedInEmailPrint分享Bloomberg:Samsung C&T Corp. will finish two more coal projects before exiting the sector.Construction of the two ventures, the Gangneung facility in South Korea and the Vung Ang 2 project in Vietnam, are scheduled to be completed in 2023 and 2024, respectively. The pledge to exit the coal industry is “unprecedented” for a non-financial firm in South Korea, the company said in a statement.The de-facto holding company of the Samsung empire has faced growing criticism over its involvement in coal amid mounting global pressure to halt use of the dirtiest fossil fuel. Activist climate investors expressed concern Samsung C&T remained committed to the two projects.Global investors are increasingly voicing concerns over the risks associated with South Korea’s overseas coal financing as the state-owned Korea Electric Power Corp., known as Kepco, continues to approve plans to invest in new projects. BlackRock Inc., the world’s biggest asset manager with a stake in the utility, urged the company to provide clear strategic rationale for its investment in new plants in Vietnam and Indonesia.Kepco’s board of directors approved a $200 million investment in the Vung Ang 2 project earlier this month. A joint venture between Samsung C&T and Doosan Heavy Industries & Construction Co. will be in charge of engineering, procurement and construction for the project, a Kepco spokesman said Oct. 6.Samsung C&T said its trading arm will also gradually exit from all coal-related businesses once its existing contracts terminate, while seeking to expand its business into LNG and renewables. The company will completely withdraw from the Gangneung project after selling all of its 29% stake, which it can do it three years after commercial operations begin in end-2023.[Heesu Lee]More: Samsung construction arm to ditch coal after 2 more projects
Linc Stallings running Class IV+ dueling waterfalls. See the full gallery. Photo: Jeremy Rogers“I’ve got a 50/50 success rate with that drop. About half the time, I swim,” Linc Stallings tells me after he negotiates our boat over a 10-foot waterfall into a deep pool flanked by massive boulders. We’re running the North Fork of the French Broad, a small stream that drops off the Blue Ridge Parkway in Western North Carolina. It’s a rain-dependent creek with class IV+ vertical drops, deep pools, and technical boulder gardens scattered throughout a two-mile stretch that’s popular with creek boaters. We’re running it in a small two-person raft called an R-2. Across the Southern Appalachians, a handful of boaters are beginning to take these small, 10-foot rafts down narrow, class IV-V creeks that have previously only been run in kayaks and the occasional canoe. It’s a niche sport that even some creek boaters think is a little crazy.“People freak out when they see rubber coming down a creek,” Stallings says. “There are only a few people who would take a raft down these narrow rivers, so people still think it’s wild.”Of those few R-2 boaters, Linc Stallings is easily one of the most experienced. The 36 year old has been guiding rafts down class V rivers for 15 years, working the biggest rivers in the South and Colorado depending on the year. He’s a rare breed: a professional raft guide, someone who’s committed to this as a career, not just something to do between college and “the real world.”“I always thought I’d do it and move on. But I just kept doing it,” Stallings says. “I love it. I love taking people out on the river. I love hanging out with other boaters. I love the water.”R-2 creeking is essentially what raft guides do on their day off. They borrow a small two-person raft from their bosses and push it, scrape it, and paddle like hell through tight rain-dependent creeks in the mountains. The North Fork of the French Broad is one of Stallings’ favorites. He first learned to creek boat here while attending Brevard College’s wilderness immersion program. He knows the nuances of every significant rapid the way a tween girl knows the lyrics to a Justin Bieber song.“A ton of people have run this creek in a kayak,” he tells me as we begin to paddle toward the first class III rapid, just 50 yards from the put-in. “But running it in a raft has a completely different dynamic. Running tight drops in this big boat is fun, but there are some logistical things you have to work out. It’s like doing a math problem.” 1 2
It’s hard to judge how soon after being sick one can take back to the bike. I guess it depends on what kind of sick it is, and what part of the body had it the worst.I, for instance, was paralyzed in my bed on Sunday with an impromptu colon cleanse. I would like to add that Sunday is my day to ride all day if I want. The one day that I am free from the chains of sticky popsicle hands, dead worms, and mopping yet another pool of pee off of the kitchen floor from…whomever.Imagine my surprise at 4 a.m. when I awoke nauseous and cramped into fetal position. The first thought is, “No! If I hold very still it will go away!” That lasted about two fragile breaths before lurching to the bathroom door in a very unquiet fashion. It’s important in my bedroom to be very quiet when navigating across the floor of Legos, sleeping puppies and laundry piles. SOME PEOPLE become very angry when such a trip becomes eventful.Well it was eventful. I even had the audacity to flush.I had just gotten back to about ten days of good running and riding with sporty new Hi-Tec trail shoes and a regular Tuesday night babysitter for rides when the shit literally hit the fan.I spent hours depleting my body of every drip of fluid before collapsing into a crumpled heap. My body ached with desire to sweat, but there was nothing left. The fan carried the smell of frying bacon into my bed, heaving me back to the bathroom…again and again.I fumbled for my phone to text for the delivery – from two rooms away – of a recovery drink that I had imagined I would be sipping at this very same hour, yet next to a cool stream with mud-splattered legs.I texted again when I couldn’t stand long enough in the window light to read the Tylenol PM bottle instructions, only to learn that I was home alone as everyone was out hiking the Mountains to Sea trail. Children born to unmarried parents are called what? I guessed the dose, which resulted in my first two hours of blissful sleep, followed by a brave foray to the deck. All of this excitement resulted in a complete 12 hours of sleep.I awoke feeling absolutely fine – just in time for a full day’s work. I couldn’t decide whether I was relieved by the timing due to the recent work schedule, or barmy. 1 2
Your daily outdoor news bulletin for September 25, the day the Little Rock Nine were escorted by armed guard into Little Rock High School in 1959:CrossFit’s Dirty Little Secret: RhabdomyolysisCrossFit is one of those things I will never understand. I get fitness , I get exertion, I get positive reinforcement and pushing yourself and all that. I get the point of CrossFit. What I don’t get is the big hubbub over what is essentially a workout routine. If you bring up CrossFit with, well pretty much anybody, the reactions are blunt and often accompanied by the red face usually reserved for the gym. WTF? Why do people care so much about how other people exercise? Haters call it a cult, CrossFitters call anyone who criticizes it a hater, and the cycle repeats itself. Unfortunately, this is the American Way, and you could take the above statement and apply it to any number of things – gay marriage, PEDs, racism, Miley Cyrus, and that’s just a quick scan of the Twitter feed. The latest argument against CrossFit comes from Eric Robertson on Medium.com in an essay titled, “CrossFit’s Dirty Little Secret.” Robertson is a professor of physical therapy at Regis University, among other things, and states the “dirty secret” of CrossFit is a condition called Rhabdomyolysis, which is essentially working your muscles so hard they explode. Well, rather, the cells that make up your muscles explode, causing permanent damage, amputation, and even death. He claims the competitive nature and culture of CrossFit causes people to blow past what their bodies can handle and put them on the path to “Rhabdo.” He makes a compelling argument, even throwing in some stuff about peeing yourself, but I’m not sure this is the biggest problem in the world. Plus, he doesn’t really have any numbers proving high rates of Rhabdo in CrossFit gyms, just that a lot of CrossFit people are aware that it exists. Weak argument. Then, if you read most of the comments on the article, the classic CrossFit, “you don’t know what we’re about so shut up” attitude is all over the place. Why do people act like this?I have never done CrossFit, but I can tell you one thing for certain: I will never, ever, ever, ever, exercise hard enough that my muscle tissue explodes. That’s for amateurs.Here is a counterpoint from HuffingtonPost contributor Ericka Andersen. Spoiler alert! Here is the last line of the piece (emphasis her’s): “Anyway, haters, stop blaming CrossFit for your problems and take some responsibility for your bad decisions.” So, there you go.Virginia Trout Stocking Shakeup in the WorksThe Virginia trout stocking program is under review, and the Department of Game and Inland Fisheries wants your input. There are a myriad of problems with the current system, but most people come down on one side or the other – I’ll classify them as fly fishermen vs. bait fishermen to make it easier. Fly fishermen want less stocking in native streams, less info on when and what streams are being stocked, they want more catch and release, they want an opening day. Bait fishermen want more fish, bigger fish, more fish, more info on when and where they are stocked, and more fish. These are the guys that follow the stocking trucks around and pull out the biggest fish with panther martins before the last fish hits the water. The DGIF is quick to point out that they do not think the system is broken, but that it can be improved. One of the biggest issues is the bottom line: the DGIF sold 100,000 trout licenses 20 years ago, but only 60,000 last year. This is a disturbing trend. The formal process of evaluating and implementing improvements will take three years – remember this is an arm of the government – and the DGIF will be assisted in their research by Virginia Tech advanced degree fisheries students Vic DiCenzo and Amanda Hyman under their professor Steve McMullin.There will be eight public meetings/hearings on the trout stocking program throughout October and all Virginia anglers are urged to attend and voice their opinion. The first is in Wytheville on September 30th.

Georgia and South Carolina are currently at odds over the Savannah River that divides their state, and the impact of any decisions will have long lasting affects on industry, drinking water, and utilities for decades. Water demands have skyrocketed in both states over the past several years from a range of sources – nuclear plants, expanding industry, and sea water encroaching on coastal communities’ aquifers being the most prevalent. And then there are the environmental and ecosystem issue raised by basically running the river dry. The good news is that the governors of both states – Nathan Deal of Georgia and Nikki Haley of South Carolina – are sitting down to talk about solutions to the water crisis in attempts to avoid getting caught up in the court system, which could then take years to resolve.This article on GreenvilleOnline.com does a great job of laying out the issues from both sides.
YESAppalachia remains heavily dependent on fossil fuels and nuclear energy, and these have a devastating impact on the land, air and water, including literally removing mountains for coal extraction. To address these concerns, we need a mix of energy efficiency and renewable energy. The smart development of wind energy in select areas of Appalachia will allow us to better tackle the challenges of meeting the ever-growing energy demand while simultaneously reducing emissions and local environmental impacts.But why should wind farms get built in Appalachia instead of off coastal shores or on windy plains? The truth is that we need wind farms built in all these areas. A study published by the National Renewable Energy Lab in 2012 highlighted that geographic diversity of renewable energy resources helps ensure a steady supply of power. If the wind isn’t blowing or the sun isn’t shining in one part of the country, it likely is elsewhere.Once built, wind farms emit no pollution, consume no water, and burn no fuel. A study published in the journal Energy Policy found that, on a per-unit of energy basis, fossil fuel power plants are 19-times worse for birds than wind turbines. This past year, more wind energy capacity was installed than any other generation resource, beating out coal, natural gas, and nuclear power.Even so, wind turbines should not receive a free pass to be installed anywhere. Wind farm developers typically take several years for a site assessment to determine potential impacts to habitats, birds and bats, and other environmental concerns. Developers sometimes undergo a viewshed study to evaluate how a wind farm will look from various viewpoints. Some evidence exists that wind farms may even help spur tourism. Certainly, people are fascinated by wind turbines. I’ve experienced their appeal myself; when planning a fly-fishing trip to West Virginia, my wife chose a bed and breakfast that had a wind-farm view. Had we been on the other side of a ridge, we wouldn’t have known a wind farm was nearby.Done in the right way, wind farms will tap the wind-rich resources of Appalachia while reducing the negative impacts incurred through traditional energy generation. While the suitability of a wind farm varies from site to site, one thing is for sure: more of them should be built in Appalachia.Simon Mahan is the renewable energy manager for the Southern Alliance for Clean Energy. NOI recognize the need for alternative energy. I am aware of the harm caused by reliance on coal, and I am concerned about global warming. Appalachian wind development, however, is more of a distraction than a solution to these problems. And it threatens some of the best of the region’s wild landscape.Ridgeline wind projects typically require extensive forest clearing and excavation for roads, turbines, powerlines, and substations. With about a mile needed for every seven turbines, even low-capacity projects result in substantial habitat loss and harm to wildlife. The environmental footprint is simply too large in relation to the benefits.Suppose, for example, we want wind-powered electricity in the summer months when minimum wind availability coincides with maximum electricity demand. Let’s say we want to supply enough electricity to replace just one relatively small 500-megawatt power plant. This very modest objective would require about 300 miles of ridgeline turbine construction, and we would still need another readily available source of power for when there is no wind.Let’s not give the wind industry a pass on environmental review. We should not back away from protection of golden eagles and other wildlife that use the mountain ridges, and projects should not go forward where high bat mortality is expected.Let’s look at other options. Offshore wind development, for example, makes more sense than wind development in the Appalachian mountains—in terms of both electricity generation and environmental cost.And let’s redirect the incentives that finance the wind industry. We could achieve much more with support for residential and urban solar development—something that will actually allow people and communities to assume responsibility for meeting their own electricity needs without harming the environment.And finally, if we are really serious about solving our energy-related problems, we should expect our elected leaders to adopt energy policies that are based on informed analysis instead of wishful thinking.Rick Webb is a senior scientist at the University of Virginia.
An Uncomplicated ChoiceWith the deluge of snack and energy bars now available, it can be hard to choose which one is right for you. Look beyond the claims on the front of the packaging that scream, “high fiber, sugar free, protein packed, etc.,” and check out what’s on the back. Ever heard of the first five ingredients? Are they whole foods? Can you pronounce them? Why does a snack bar have to be so complicated? Maybe it doesn’t.We sat down with Talia Klein, owner of Uncomplicated Foods, and creator of Tali-O Bites, to learn more about these bars, her company and her mission to bring the world less complicated, more satisfying foods.BRO: What inspired you to start Uncomplicated Foods?TALIA: I started making bars several years ago for my own person eating enjoyment, and I had no intention of ever starting a business. I started making my own bars because, honestly, I was so tired of all the bars that I was buying. I wanted a healthy snack to eat that was satisfying and tasty, so I played around with different flavors and ingredients until I was happy. My friends would always ask me what I was eating, since I would pack my bars everywhere I went, and after they tried them they started asking me if I would make some for them…so I did, happily. After a few months of regularly making bars for my family and friends, I was encouraged to start a business. I felt very encouraged, so I went for it!BRO: What was missing in the marketplace that you saw a need for?TALIA: Bites, but I didn’t know that when I started. In fact I had no intention of making bites. When I first started I was only making 2-oz. bars, which is larger than most bars on the market. I found that when I was really hungry, I could eat one of my bars easily. However, when I was mildly hungry or just wanting a little bit to hold me over, eating a whole bar was too much. So I decided to create TALI-O Bites. I have two sizes of the bites, a 2-oz. and a 6-oz. bag of bites, both in resealable bags.BRO: What makes your bars different?TALIA: Our Bars and Bites have really unique flavor profiles, like our Taste the Tahini Bar, which has the subtle hint of tahini and ginger. All of our bars have very similar ingredient, but when you taste them all, you will be amazed at how different from one another they actually are. Sadly, there are many bars out in the marketplace that are promoting health and nutrition, but in actuality they are glorified candy bars. Tali-O Bars and Bites have no added sugars, period. Our number one ingredient for all our bars and bites are dates, and I have created a recipe that allows the natural sugars to be just enough. Our bars are also very well balanced in terms of their carbohydrates, proteins, and fats. There is a lot of fiber in all of our products which helps make your body feel full and slows down the absorption of sugars into the bloodstream. So when you eat a Tali-O you get a sustained energy from the sugar in the dates without a huge spike in your insulin levels.BRO: What sports/activities are your bars ideal for?TALIA: I personally eat some bites before I head into a yoga class for a little bit of energy to get me through. I have had fans of TALI-O tell me that they love throwing a bag of bits in their gym bags, eating them after a long bike ride, after a Crossfit class, while on a paddleboard, and while hiking. Our motto is “Get Out and Go”, so really any activity. We love it when our fans send us pictures of them enjoying their favorite activities fueled by Tali-O’s.BRO: How long will your bars/bites last?TALIA: Our bars and bites have a great shelf life. I like to refrigerate my Tali-O’s, however that is not necessary; but in the refrigerator they can last up to a year. If you want to keep your Tali-O’s at room temperature they will last for 3-4 months. I would suggest that you keep them out of direct sunlight to keep the all-natural ingredients from oxidizing.BRO: Where can consumers purchase your product?TALIA: From our website: www.uncomplicatedfoods.com. We are hoping to get in stores all across the country, but as a small company we are only in a handful of places in Seattle right now. All of our bars are handmade and ship within one to two days of an order being placed. All orders over $30 dollars come with free shipping, so stock up!BRO: What beer pairs best with your bars?I think Guinness would go great with our bars, especially our Powerfully Peanut bar. Hmmm… I might have to try that right now!–TALI-O is offering BRO readers a 15% discount! Enter the promo code luckyme2 at checkout. Deal ends July 30 with no limit to how many times it can be used.
You ride your bike long enough, you’re gonna eat it sooner or later. Especially if you ride in a place like Pisgah National Forest, where the trails can be steep and stacked with off camber root gardens, mandatory boulder drops and little gnomes that jump out of the woods and push you off your bike. Sometimes, it doesn’t even take burly singletrack or mythical woodland creatures to knock you off your bike. Sometimes, you’re going 25 mph down a gravel road after surviving 20 miles of non-stop technical singletrack and combative gnomes and you do something stupid, like take a hand off the handlebars to adjust your helmet, and right then your front tire hits a babyhead in the middle of the road and your handlebars twist. And it happens fast, because you’re going 25 mph, so before you know it, you’re on the ground, elbow and shoulder first, then your face and knees. The bike lands on top of you, like a painful blanket.Ah, mountain biking.Shit happens. The only thing you can do is get back up, make sure nothing’s broken and keep pedaling. But what do you drink to ease the pain when it’s all over? When you’re back home and your picking gravel out of an open wound in your knee? That’s the real question.“Drink some whiskey and rub some dirt on it?”That’s what my buddy suggested after I picked myself up off the gravel.There’s a certain traditional logic to the suggestion. Think of all those great movies where the hero downs a shot of brown stuff and bites down on a strap of leather while his partner digs a bullet out of his shoulder.At this point, drinking a tall glass of bourbon while licking my wounds after eating shit on my bike has become a bit of a tradition for me. The way I do it doesn’t look exactly like those cliché hero/action movie scenes. I tend to whimper more than those dudes in the movies. Typically, nobody is pulling a bullet out of my body. Instead, it’s my wife hovering over me, silently recounting all of the other guys she could’ve married. Bankers and doctors who don’t come home broken and bloody. My ritual usually ends with my wife applying a Hello Kitty Band-Aid to my wound. So really, it looks nothing like those action movies. Except the whisky. That part’s the same.
