A solar-storage microgrid demonstration at a California hospital aims to deliver substantial energy cost savings, as well as enhance reliability, resiliency and environmental quality. Renewable energy microgrids, such as the one up and running at Kaiser Permanente's Richmond Medical Center, have the potential to reduce hospitals' energy bills by … [Read more...]
Cuttyhunk witnessed New England’s whale oil industry give way to kerosene and incandescent light bulbs. Now the tiny island is deep in another energy revolution -- reducing diesel use by way of a solar plus storage microgrid. With a $2.1 million microgrid in operation since the early spring, the fishing mecca offers good argument for pursuing … [Read more...]
Results of a microgrid survey released today by Microgrid Knowledge show Siemens to be the most recognized name in microgrids among 21 companies. The independent survey also found electric reliability to be the biggest reason for installing a microgrid. Financing serves as the biggest hindrance. We conducted the online poll over the spring … [Read more...]
Microgrid-like future takes flight Solar Impulse, an ABB-backed solar plane, took off from Hawaii this week to demonstrate what a microgrid-like future will look like. The plane is attempting a 40,000-kilometer flight around the world using solar power and battery energy storage. “We had to build an aircraft with an extremely efficient grid: … [Read more...]
This was a big week in microgrid financing with three company announcements. First, UGE International secured a $1.83 million (12 million RMB) loan from the Bank of China. UGE will use the money in part to fulfill payment of the cash portion of the UGE's proposed acquisition of large-scale solar energy system provider Endura Energy … [Read more...]
The term ‘non-transmission alternative’ may sound wonky to some. But to companies that work with microgrids, distributed energy, energy efficiency and the like, it sounds like opportunity. The term refers to installing smaller, local energy technology instead of new transmission infrastracture to alleviate congestion. Several states see … [Read more...]
We hear a lot about the need for microgrids in India where remote villages lack access to the central grid. But it appears that microgrids could help out India’s central grid as well. The U.S. Energy Information Administration reported last week that India has among the world’s highest electricity line losses – the disappearance of electricity … [Read more...]
America is good at making enough electricity to serve its increasingly plugged-in economy. Ample juice is flowing. Problem is, there is no place to plug in. We are becoming a nation beset by socket insecurity. Watch the weary traveler in almost any airport, on the hunt for a charging kiosk to save his cell phone before its final tweet. … [Read more...]
An electrical socket is probably the most disinteresting technology in any home. But place a charging system in a city parking lot for the first time -- one meant for an electric vehicle -- and you’ll inevitably find people standing around marveling. And for good reason. EVs promise to radically change transportation. Creating efficient and … [Read more...]
Since MicrogridKnowledge.com recently celebrated its one-year anniversary, we thought this would be a good time to give you some insight into who – and what’s – capturing reader attention. So here are the top read articles for the last six and 12 months. The Oncor microgrid wins the six-month prize. And for the year, the most read story was … [Read more...]
There are multiple approaches to funding microgrid projects. Eric Dupont, executive vice president and chief commercial officer at PowerSecure, discusses why CAPEX versus OPEX become important considerations in this interview with Yasmin Ali, Microgrid Knowledge contributor.
In this paper, new voltage sensitivity indexes are proposed to search and evaluate the candidate buses in a microgrid, where the energy storage systems can be installed to contribute most effectively to the system. To learn more about optimized energy storage in a microgrid download this white paper.
