The Public Utilities Commission of Hawaii is pushing back against Hawaiian Electric Companies (HECO) proposed integrated grid plan (IGP) because it has not given sufficient consideration to non-wires alternatives. HECO may be prematurely excluding non-wires alternatives and “significantly” delaying the proposed soft launch of its IGP, the … [Read more...]
Severe heat and storms across the US this summer have strained the electric grid and caused extensive power outages. But the microgrids are working. Consider what happened on July 20 in northeast and north central Wisconsin when a thunderstorm knocked out power to 240,000 customers, leaving 50,000 with no power for two to three days. The … [Read more...]
While it may seem that microgrids are new, the history of microgrids shows they have been around in some form for years in the US — although they haven’t always been called microgrids. The first one was introduced by Thomas Edison in 1882 at his Pearl Street Station, which combined heat and power and produced electricity and thermal … [Read more...]
In a filing before the Federal Energy Regulatory Commission (FERC), Alternative Transmission (ATI) proposes a technology that could bring a new meaning to the concept of non-wires alternatives. Based in Sullivan’s Island, S.C., the company wants to move batteries by rail for discharge and charge where needed on the electric grid. Further, … [Read more...]
Non-wires alternatives (NWAs) use distributed energy resources and microgrids to defer or replace the installation of more traditional 'wires and poles' infrastructure. When utilities choose non-wires alternatives, they often save ratepayers money by avoiding investments in costly infrastructure. By utilizing distributed energy resources (DER) at … [Read more...]
Erik Svanholm, vice president, non-wires alternatives for S&C Electric, defines the term 'non-wires alternatives' and gives examples of how microgrids can provide these alternatives to traditional investments in wires and the transmission grid during an interview with Microgrid Knowledge's Elisa Wood at Microgrid … [Read more...]
Eversource plans to develop an energy storage microgrid in New Hampshire that takes the local energy concept to a new level by pairing the microgrid with a bring-your-own-device program. The project also offers an example of a path for utilities to develop microgrids when state rules allow utility ownership of energy storage. Charlotte … [Read more...]
We worry about the big calamities like hurricanes and cyberattacks that cause long power outages. But let’s face it, for most of us momentary outages are more likely to disrupt our daily lives. Mike Edmonds, chief commercial officer for S&C Electric, thinks about this when his 5-year-old son calls out: “Alexa, bedtime story!” Raised … [Read more...]
Developers and technology companies worldwide continue to focus on electrifying energy-poor areas of Africa. Recent example: 40,000 residents and businesses in the northeast African country of Eritrea now have reliable electricity thanks to two new minigrids. Developed by UK-based Solarcentury, the minigrids (Africa's term for microgrids) … [Read more...]
Microgrids that regulators determine “serve the public interest” are back in play in Maine this year as lawmakers try to pass a bill that fell short a year ago. Legislators passed a bipartisan bill last year more clearly defining how microgrids could be created, but former Republican Gov. Paul LePage vetoed it. Newly elected Gov. Janet Mills … [Read more...]
Peter Asmus describes findings from a new report by Navigant Research that shows market opportunity for microgrids in every region of the world. Asia Pacific is the top market, especially for remote microgrid systems.
This paper describes the design and operation of the microgrid installed for the US Department of Defense at Fort Sill, Oklahoma. To learn more about how to design and operating a microgrid download this white paper.
