Duck Curve
The duck curve is a graph of power production over the course of a day that shows the timing imbalance between peak demand and renewable energy production. Used in utility-scale electricity generation, the term was coined in 2012 by the California Independent System Operator. Solar power In some energy markets, daily peak demand occurs after sunset, when solar power is no longer available. In locations where a substantial amount of solar electric capacity has been installed, the amount of power that must be generated from sources other than solar or wind displays a rapid increase around sunset and peaks in the mid-evening hours, producing a graph that resembles the silhouette of a duck.Paul Denholm, Matthew O'Connell, Gregory Brinkman, and Jennie Jorgenson.Overgeneration from Solar Energy in California: A Field Guide to the Duck Chart NREL/TP-6A20-65023.

ZDNet
ZDNET is a business technology news website owned and operated by Red Ventures. The brand was founded on April 1, 1991, as a general interest technology portal from Ziff Davis and evolved into an enterprise IT-focused online publication. History Beginnings: 1991 to 1995 ZDNET began as a subscription-based digital service called "ZiffNet" that offered computing information to users of CompuServe. It featured computer industry forums, events, features and searchable archives. Initially, ZiffNet was intended to serve as a common place to find content from all Ziff-Davis print publications. As such, ZiffNet was an expansion on an earlier online service called PCMagNet for readers of PC Magazine. Launched in 1988, PCMagNet in turn was the evolution of Ziff Davis' first electronic publishing venture, a bulletin board, which launched in 1985. On June 20, 1995, Ziff-Davis announced the consolidation of its online information services under a single name, ''ZD Net''. The service had ...

Profit Margin
Profit margin is a measure of profitability. It is calculated by finding the profit as a percentage of the revenue. \text = = There are 3 types of profit margins: gross profit margin, operating profit margin and net profit margin. * Gross Profit Margin is calculated as gross profit divided by net sales (percentage). Gross Profit is calculated by deducting the cost of goods sold (COGS) from the revenue, that is all the direct costs. This margin compares revenue to variable cost. It is calculated as: \text = \text - (\text + \text + \text) \text = \text - \text - \text \text = * Operating Profit Margin includes the cost of goods sold and is the earning before interest and taxes ( EBIT) known as operating income divided by revenue. It is calculated as: \text = * Net profit margin is net profit divided by revenue. Net profit is calculated as revenue minus all expenses from total sales. \text = Overview Profit margin is calculated with selling price (or revenue) taken as base t ...

Hornsdale Power Reserve
Hornsdale Power Reserve is a 150 MW (194 MWh) grid-connected energy storage system owned by Neoen co-located with the Hornsdale Wind Farm in the Mid North region of South Australia, also owned by Neoen. The original installation in 2017 was the largest lithium-ion battery in the world at 129 MWh and 100 MW. It was expanded in 2020 to 194 MWh at 150 MW. Despite the expansion, it lost that title in August 2020 to the Gateway Energy Storage in California, USA. The larger Victorian Big Battery began operations in December 2021. During 2017 Tesla, Inc. won the contract and built the Hornsdale Power Reserve, for a capital cost of A$90 million, leading to the colloquial Tesla big battery name. In November 2019, Neoen confirmed that it was increasing capacity by a further 50MW/64.5MWh to a combined 193.5 MWh. The increased storage capacity was installed by March 23, 2020, and the increased power became operational in early September 2020. Construction South Austra ...

Peaking Power Plant
Peaking power plants, also known as peaker plants, and occasionally just "peakers", are power plants that generally run only when there is a high demand, known as peak demand, for electricity. Because they supply power only occasionally, the power supplied commands a much higher price per kilowatt hour than base load power. Peak load power plants are dispatched in combination with base load power plants, which supply a dependable and consistent amount of electricity, to meet the minimum demand. Although historically peaking power plants were frequently used in conjunction with coal baseload plants, peaking plants are now used less commonly. Combined cycle gas turbine plants have two or more cycles, the first of which is very similar to a peaking plant, with the second running on the waste heat of the first. That type of plant is often capable of rapidly starting up, albeit at reduced efficiency, and then over some hours transitioning to a more efficient baseload generation mode. C ...

Southern California Edison
Southern California Edison (or SCE Corp), the largest subsidiary of Edison International, is the primary electricity supply company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric (SDG&E), Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Other investor-owned utilities (IOUs) in California include SDG&E, PacifiCorp, Bear Valley Electric, and Liberty Utilities. Southern California Edison (SCE) still owns all of its electrical transmission facilities and equipment, but the deregulation of California's electricity market in the late 1990s forced the company to sell many of its power plants, though some were probably sold ...

Battery Storage Power Station
A battery storage power station is a type of energy storage power station that uses a group of batteries to store electrical energy. Battery storage is the fastest responding dispatchable source of power on electric grids, and it is used to stabilise those grids, as battery storage can transition from standby to full power within milliseconds to deal with grid failures. At full rated power, battery storage power stations are generally designed to output for up to a few hours. Battery storage can be used for short-term peak power and ancillary services, such as providing operating reserve and frequency control to minimize the chance of power outages. They are often installed at, or close to, other active or disused power stations and may share the same grid connection to reduce costs. Since battery storage plants require no deliveries of fuel, are compact compared to generating stations and have no chimneys or large cooling systems, they can be rapidly installed and placed if n ...

Lithium-ion
A lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles. It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other rechargeable battery technologies, Li-ion batteries have high energy densities, low self-discharge, and no memory effect (although a small memory effect reported in LFP cells has been traced to poorly made cells). Chemistry, performance, cost and safety characteristics vary across types of lithium-ion batteries. Most commercial Li-ion cells use intercalation compounds as the active materials. The anode or negative electrode is usually graphite, although silicon-carbon is also being increasingly used. Cells can be manufactured to prioritize either energy or power density. Handheld electronics mostly use lithium polymer batteries (w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
