Hello, friends! In the article we touched upon the issue of Li-Ion solutions (drives, batteries) for power systems of the private and industrial sector. I propose a translation of a summary of fresh short news from the United States dated March 3, 2020 on this topic. The keynote of this news is that stationary lithium-ion batteries of various structures are steadily replacing the classic lead-acid solutions, and Tesla has made a significant contribution. The practice of operating electric vehicles makes it possible to assume excellent prospects and safety of lithium solutions for power systems and industrial equipment such as UPS and auxiliary direct current systems (SOTS). These solutions in Russian are called high-capacity batteries (ABBM), in the English-language literature this is the term - Energy Storage System-ESS. To begin with, let's assess the situation in the homeland of Elon Musk's company, in the future, we will continue to publish on this topic systematically, since the "news from the fields" arrive quite rapidly.
One of the most powerful energy system storage projects approved for PG&E
The Monterey County Planning Commission (central California, USA - author's note) approved a project for a giant 182,5 MW, 730 MW / h energy storage system called Elkhorn Battery Energy Storage System for Pacific Gas and Electric (PG&E) to be located in Moss Landing, California. Behemoth is one of four significant energy storage projects first proposed for California's South Bay by PG&E in July 2018. What batteries will this system use? Tesla Megapack (Tesla Megapacks). Moreover, Elkhorn is not the largest of the proposed four. The flagship should be the proposed but not yet approved Dynegy-Vistra 300 MW, 1200 MW/h project. And if Elkhorn does not cover the requirements for energy storage in the power system, the continuation of the project and positive decisions are a foregone conclusion. Source:
Montana Regulator Says NorthWestern Isn't Fair to Renewable Electricity
Montana's own regulator adviser believes NorthWestern's resource plan is unfair to solar, wind and storage: The utility's plan to spend close to a billion dollars on gas-fired power plants was "a foregone conclusion" given the choice of an industry development model "that favors thermal resources over renewables." and vaults,β he said in for consultant Synapse Energy Economics. In addition, several "serious" miscalculations in the utility's resource procurement "limit the ability of resources to compete to meet the needs of the Northwest," the study said.
The Montana Public Service Commission hired Synapse to evaluate NorthWestern Energy's planning efforts. Synapse had limited access to the model (Software product/complete analytical platform for energy portfolio planning, capacity expansion and financial analysis - author's note) of NorthWestern and did not have access to perform their own runs of the model. Last autumn (environmental organization in the USA, founded in 1892 - author's note), suspecting biased NorthWestern modeling, to the utility model file.

SolarEdge launches new network controller
Company launched a new inverter solution called , a load management tool for power system failures. The site controller switches the inverter to an alternative power source mode that simultaneously maximizes solar power generation and supplements it with power from a diesel generator when needed to meet the energy demand on site, as well as providing overload protection. Simply put, the controller allows homeowners to easily integrate as many power sources as they need during an outage, with solar power being the main source. The system layout is shown below.

America's first sunny city
The culmination of a former NFL player's dream and the largest land preservation deal in the state of Florida, Babcock Ranch is an 18-acre community that holds the palm as America's first and only sunny city. The city is powered by 000MW solar energy, solar power center ,Florida, in combination with a 10MW, 40MWh battery center operated by Florida Power and Light. This electricity serves 500 homes, although creator Sid Kitman's vision is to increase this number to 19. The city also has solar installations in many residential and commercial buildings, while every new home is connected to electricity from electric vehicles. Babcock Ranch also has many electric vehicle charging stations. You can read Lavanya Sunkara's full account of her visit to the city in the article. . You can also read the author's article on Linkedin, (Mark Wilkerson), a 34-year-old solar energy researcher who is about to move to Babcock Ranch.
