Tag: distributed energy

Distributed energy, also district or decentralized energy is generated or stored by a variety of small, grid-connected devices referred to as distributed energy resources (DER) or distributed energy resource systems. Conventional power stations, such as coal-fired, gas and nuclear powered plants, as well as hydroelectric dams and large-scale solar power stations, are centralized and often require electricity to be transmitted over long distances. By contrast, DER systems are decentralized, modular and more flexible technologies, that are located close to the load they serve, albeit having capacities of only 10 megawatts (MW) or less.

Hubbell Control Systems
The PowerHUBB platform is a combination of software and controls, luminaires, and infrastructure. It uses intelligent sensors, intuitive user interfaces, and scalable PoE technology to bring it all together. A PoE node acts as an intelligent lighting hub by receiving power and data from the network switch. This

Boosting energy efficiency remains a top goal of building owners across the country. And why not? Rising utility bills can cause a company’s bottom-line to plummet.

The Future of Fuel Cells

The Future of Fuel Cells

In motor racing, a fuel cell consists of a container that protects a bladder and baffle so that, in the event of a crash, the fuel is contained, keeping the driver safe from fire. In the broader context, fuel cells are devices that convert stored chemical energy into electrical energy,

Vehicle to Grid

Vehicle to Grid

As often happens, two new technologies can merge their functions to create a new solution to a problem that neither could have solved on its own. In the past few years, two different technologies have achieved a tipping point: renewable energy in all of its forms—but especially photovoltaic solar cells

Editor’s Comments: Incremental Growth

If you’ve ever looked closely at a seashell, you know the wonder encapsulated within the graceful spiral of its pearlescent form—what Frank Lloyd Wright called “nature’s most perfect architecture.” The shape is at once sculptural and mathematically precise.

Many sea creatures take a modular approach to expansion. Because their calcified exoskeletons

A Breakthrough for Batteries

A Breakthrough for Batteries

Lithium-based batteries have been restricted by the limited availability of cobalt. More than 50% of all cobalt produced globally is used in energy storage devices. A majority of that is mined in the Republic of Congo, oftentimes by children.

Lithium-based energy storage technology relies on cobalt because of the metal’s ability

Shared Storage

Shared Storage

It takes a village to power the globe. We’ve discussed a patchwork quilt approach to energy distribution previously in the context of microgrid clusters and community solar projects. However, community energy storage is another emerging concept that shows great promise for helping grid operators integrate renewables into energy systems and

Uninterruptible Power Supplies and Distributed Energy Systems

Uninterruptible Power Supplies and Distributed Energy Systems

An uninterruptible power supply (UPS) is defined as, “A device that provides battery backup when the electrical power fails or drops to an unacceptable voltage level. Small UPS systems provide power for a few minutes, enough to power down the computer in an orderly manner, while larger systems have enough

Managing Multiple Microgrids

Managing Multiple Microgrids

Last week I traveled to Chicago where, as a participant in Siemens’ US Innovation Day, I had an opportunity to explore a number of exciting technology advancements. One of the innovations that I found interesting was the concept of aggregated microgrids managed by a utility.

At the event, Siemens announced that
