ERCOT’s Tight Reserve Margin and Renewable Energy: What’s it All Mean for Texas Businesses?

Texas

It’s been a hot summer in Texas, even into September, with the Electric Reliability Council of Texas (ERCOT) again last week urging customers to use less electricity. Given these events, and new renewable energy options, businesses in the state are — no doubt — thinking about their energy choices. Microgrid Knowledge will explore issues … [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...]

What to do about Massachusetts’ Sputtering Solar Market?

solar energy target

With solar installations down dramatically in Massachusetts, a national advocacy group is calling for the state to triple its solar energy target to 4,800 MW. In a new report, Vote Solar says that the policy change is crucial if the state expects to meet its clean energy goals and generate solar jobs. The new target would apply to Solar … [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...]

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...]

Water but No Grid: A Microgrid Solves Dilemma for UAE Agricultural Operation

off-grid microgrid

There was water, but no electric grid at the site Themar Al Emarat chose for its new hydroponic farm in the United Arab Emirates (UAE). The agricultural company found the solution in a 5.94 MW off-grid microgrid. Key to the farm's success is the ability to cool and chill water for cultivating mushrooms, lettuce and other crops for local … [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...]

Researching the Human Side of Microgrids, Too, for Storm-Battered Tallahassee

Battered by Hurricane Michael last year, the City of Tallahassee and researchers are trying to design a storm-hardened microgrid system, one that considers both engineering and human psychology. The city is working with a cross-disciplinary research team from Colorado State University (CSU) that won a  $194,000 grant in June from the National … [Read more...]

Does Your Microgrid Have Enough Computing Power?

microgrid computing power

Microgrids need to have enough computing power to operate even if a facility is experiencing connectivity issues, says Joseph Gottlieb, CTO of Rhombus Energy. His company builds software to meet this need. "It's a booming business," he says in an interview with Elisa Wood, editor-in-chief of Microgrid Knowledge at Microgrid 2019. Rhombus … [Read more...]
