Switchgear - Wikipedia

In an electric power system, switchgear is composed of electrical disconnect switches, fuses or circuit breakers used to control, protect and isolate electrical equipment. Switchgear is used both to de-energize equipment to allow work to be done and to clear faults downstream. This type of equipment is directly linked to the reliability of the electricity supply. The earliest central power stations used simple open knife switches, mounted on insulating panels of marble or asbestos. Power levelsGet price

How the top US microgrid developers do business | Wood Mackenzie

Technology-Neutral Versus Product-LedStrategy and ScaleWhatNext?According to my recent research insight, these 17 developers all employ either a technology-neutral or a product-led strategy. Technology-neutral developers typically integrate a generation or energy storage asset on the customer site that predates the microgrid. These developers are generally microgrid control companies, energy service companies or engineering, procurement and construction providers. In contrast, product-led developers focus on standardized generation and energy storage products. These systems are often installed on sites that do not have existing generation or storage assets. While some product-led developers integrate standardized energy storage and generation systems, these solutions tend to rely on a generation asset. These companies can be organized based on the type of product they provide: natural-gas-fueled products, diesel or solar-plus-storage.Get price
