Tesla Megapacks to Store Solar Energy for Switch Data Centers in Nevada

  • Three massive solar energy generation projects underway in Nevada that will power data centers by Switch, among other things, will rely on Tesla’s new utility-scale energy storage technology to ride through periods when the sun isn’t shining.
  • Las Vegas-based Switch has made a 25-year purchase agreement for solar and battery power from Capital Dynamics, which will own the overall project, said Adam Kramer, executive VP of strategy for Switch.
  • Located in Boulder City, Nevada, Townsite originally was expected to produce 180MWac/231MWdc, and the companies said last year that it was planned to also feature a 90MWac/360MWh energy storage facility.
  • The other new solar project is in Clark County (which includes Las Vegas) and consists of 188MW of solar and 200MWh of battery storage, the company said.
  • The third project, Citadel, will produce 127MW of solar power and have 240MWh of battery storage, is located in Storey County.

Court Ruling Clears Way for Energy Storage on the Grid. Who Benefits?

  • A federal appeals court has cleared the way for large-scale energy storage projects to have similar access to the power grid as electric generators do.
  • Using the Electricity Reliability Council of Texas, ERCOT, market as an example, peak demand is forecast to reach 75,000 megawatt hours (mWh) in August 2020.
  • However, the average electricity demand in ERCOT throughout the year is approximately 45,000 mWh. Battery storage would help reduce the need for a portion of the generation fleet and hasten the retirement of older high-cost generators.
  • While ERCOT and the Public Utility Commission of Texas have obligingly dithered over battery access to their grid, utilities across the nation challenged FERC in court on essentially the same matter, arguing that in Order No. 841 FERC overstepped its jurisdiction into local markets by “barring States from ‘broadly prohibiting’ local [Electricity Storage Resources] from participating” in the electricity markets.

Google Pixel 4A review: back to basics for $349

  • It’s cleaner and less cluttered than other versions of Android, it’s guaranteed to get at least three years of timely software updates, and — perhaps most importantly — Google’s software is what makes the Pixel camera so good.
  • The word I use most often to describe Pixel hardware is “unassuming.” It’s basic: no frills, no fanciness, just an easy-to-hold phone without any embellishments.
  • Where Apple can use its economies of scale to put the fastest mobile processor ever made into its low-cost iPhone SE, Google has to make do with the options Qualcomm offers at this price point.
  • Out of the box (and after Android gets over the usual first-day sync chug), it’s the kind of phone I would be happy to use every day.
  • Google promises at least three years of software updates and says last year’s Pixel 3A (which also has a lower-tier processor) is aging well, but it’s something to think about.

Pixel 4a review: The best $350 phone

  • It also offers helpful Pixel-only tools like Live Caption for Calls, Call Screening, Recorder and Personal Safety features.
  • Though it only comes in one color option and just a single rear camera, the Pixel 4a still manages to be the best phone for the price.
  • Other midrange phones like the Galaxy A51, the iPhone SE and even the Oneplus Nord (which isn’t available in the US) also come in just one size, after all.
  • Yet, Google is also playing catchup -- the OnePlus Nord and Galaxy A51 both offer similar screens with camera cutouts, that measure 6.4 and 6.5 inches respectively.
  • Google’s software tends to make up for its basic hardware, and as usual, the company has some helpful tools that make the Pixel experience better than any other Android phone.
  • For now, though, features like Live Caption, Call Screening, Recorder and Personal Safety are what set the Pixel 4a apart from the competition.

PS5 DualSense Leak Teases the Battery Upgrade We All Deserve

  • The PS5’s DualSense controller will reportedly offer a vast improvement on the PS4’s DualShock 4 when it comes to battery life.
  • According to a Reddit user, who was able to sample a prototype of the controller, the DualSense will up the battery life by three to four hours compared to the DualShock 4.
  • A follow-up post appeared yesterday from someone associated with the Reddit user, offering additional insight into the DualSense, including the extended battery life.
  • We also took thoughtful consideration into ways to maintain a strong battery life for DualSense’s rechargeable battery, and to lessen the weight of the controller as much as possible as new features were added.
  • According to the Redditor, the DualSense’s D-pad and buttons are near enough identical to those of the DualShock 4, although the Touchpad responsiveness is improved, with a more ‘clicky’ feel.

A $13,000 electric car will go on sale in the US by late 2020

  • You’ll soon have the opportunity to buy a brand new electric car under $15,000 in the US — if you’re willing to make a few sacrifices.
  • TechCrunch reports that Chinese automaker Kandi plans to launch two low-priced EVs in the US by the end of 2020, headlined by the tiny K27 (shown above).
  • It’ll launch alongside the K23, a slightly larger vehicle that should cost $29,999 before credit, and $22,499 after.
  • This still helps Kandi fare well against many EVs. The “off menu” Tesla Model 3 starts at $35,000 before incentives, for instance, while even a used Fiat 500e might cost more.
  • You’ll be out of luck if you want to buy one in EV havens like the San Francisco Bay Area, at least for a while.
  • Vehicles like these could pressure other brands to lower the price of entry for EVs and usher them into the mainstream.

Why vehicle-to-grid charging could be the cheapest way to secure renewable energy

  • This is where large grid-scale energy storage systems could help regulate and buffer supply and demand, and improve grid control.
  • This is a concept known as vehicle-to-grid (V2G), and could create a much larger and cheaper alternative energy store than stationary large battery systems.
  • If these were all battery electric vehicles (each storing an average of 50kWh of energy and connected via a 7kW charger), this could create a nationwide distributed mega battery with a capacity of 220.5GW.
  • The costs of this aggregated battery would also be much easier to bear as individual vehicle owners would purchase the cars and batteries, instead of government and private investors having to spend millions on big projects.
  • So while the UK government is correct that the national grid needs more energy storage to support the shift to further renewable energy generation, a focus on building large, expensive batteries isn’t necessarily the answer.

NFL suspends Antonio Brown eight games for violating personal conduct policy

  • Brown, 32, is eligible to participate in all preseason activities with any team he signs with and return after the team's eighth game, the NFL said.
  • Brown spent most of his career with the Pittsburgh Steelers.
  • He played one game for the New England Patriots last season before being released.
  • Brown had been under NFL investigation for multiple off-field incidents.
  • He was sentenced to two years of probation in June.
  • NFL.com says the suspension is related to Brown's no contest plea to burglary and battery charges, and accusations he sent intimidating texts to a woman.
  • Brown's attorney and agent said he will not appeal, NFL.com says.
