Nation’s Largest Residential Battery Demand Response System Being Built in Utah

virtual power plant

A new 600-unit apartment complex and sustainable community in Utah's Salt Lake Valley will feature a virtual power plant (VPP) that its backers say will be the largest residential battery demand response system in the US. Local utility Rocky Mountain Power will manage the virtual power plant to shave peak demand and provide behind-the-meter … [Read more...]

Study Warns that Gas Plants Could become Stranded Assets

clean energy portfolios

Utilities, investors and regulators should stop the rush to natural gas and choose clean energy portfolios (CEP) made up of combinations of solar, wind, storage, efficiency and demand response, warns a new report from the Rocky Mountain Institute (RMI). If they don’t, many gas plants will become stranded assets, raising the specter that … [Read more...]

Flash-Charging E-Bus System in China Expected to Charge in Seconds

A collaboration between ABB and China electric bus (e-bus) manufacturer King Long Motor Group holds the promise of a flash-charging system for e-buses that opens the door to electric vehicle-to-grid and development of urban microgrids. ABB and King Long are in the midst of developing a pilot project in China. King Long is designing and … [Read more...]

Exploring the Power of EPA Tier 4 Final Stationary Engines for On-Site Power Generation

Stationary Engines

There are many reasons why enterprises and organizations choose to install stationary engines at their facilities for on-site power. For example, they may use the generators for standby power, base-load power or built-in redundancy for critical assets. Stationary engines collectively have had an impact on air quality and public health. So … [Read more...]

Hawaiian Island will Create a Virtual Power Plant from 1,000 Solar Homes

virtual power plant

Sunrun and Open Access Technology International (OATI) will create what they describe as the world's largest residential virtual power plant (VPP) by managing the electricity from some 1,000 rooftop solar-plus-storage systems to be installed on the Hawaiian island of O'ahu. Under a four-year contract beginning in 2020, Sunrun and OATI will … [Read more...]

Microgrids Already on their Way to the Bahamas…Just Not Fast Enough

bahamas

Often communities don’t even start to think about microgrids until after a disaster, giving rise to the adage ‘follow the carnage’ to describe a common path to microgrid development. But in the Bahamas, if there is any good news, it’s that microgrids were already on their way before Hurricane Dorian. The head start is a result of … [Read more...]

Using Hardware-in-the-Loop Testing throughout Microgrid Lifecycle

hardware-in-the-loop testing

The last entry in a new Microgrid Knowledge special report, released in partnership with Typhoon HIL, highlights how microgrid developers can use Hardware-in-the-Loop testing throughout a microgrid's lifecycle, not just during the design and construction phase.  Verification of protection coordination  Hardware-in-the-loop testing is a … [Read more...]

Researchers Propose Floating Microgrids Made up of Electric Boats

electric boats

Electric boats may enable floating microgrids that could serve islands that have historically been powered by fossil fuels, according to a report from researchers at the University of New South Wales in Sydney, Australia. “Powering small islands with reliable, affordable and green electricity is a big challenge due to their dispersed … [Read more...]

Microgrids Made Easier — and Smarter — with Software that uses Artificial Intelligence

microgrids

Good things don't always come easily. Microgrids are no exception. "The process of developing microgrids can be costly. It begins with a feasibility study reaching hundreds of thousands of dollars, even before any design, procurement and installation," said Kay Aikin, CEO of US-based Introspective Systems."Moreover, those feasibility studies … [Read more...]

Walk Through the Last of the Microgrid Development Phases: Implementation

microgrid development phases

This guest post is adapted  from a new white paper from the DOE's Rima Kasia Oueid that outlines the three microgrid development phases for public critical infrastructure microgrids. This entry explores Phase 3: Implementation.  Implementing a microgrid requires significant time, effort and investment. There are many cost variables that must … [Read more...]
