South Australia Plugs in World’s Largest Battery

Tesla’s installation is designed to ease grid overloads during periods of high demand

Posted on Dec 8 2017 by Scott Gibson

The world's largest lithium ion battery is up and running in South Australia where officials hope it will help reduce power shortages during blistering summer weather that lies ahead.

The state government announced last week that the football-field-sized battery has been installed at the Hornsdale Power Reserve, where it will store energy generated at an adjacent wind farm. According to a statement from South Australia Premier Jay Weatherill, the battery is "history in the making" and will ensure that the state has backup power to get it through the summer.

On-Site Storage Is the Great Equalizer

Energy storage is a new technology that addresses a variety of issues raised by decentralized electricity production

Posted on Dec 28 2016 by Bruce Sullivan

We are now in a world where decentralized electricity production, such as rooftop solar, is more viable than ever for the public and more threatening than ever to utilities. The public is more willing to adopt in-home renewables thanks to reliable technology, solid performance, declining costs, and the growing availability of loans.

Is ‘Range Anxiety’ Really Justified?

A new study finds that today's electric cars can cover the vast majority of daily U.S. driving needs

Posted on Sep 22 2016 by Anonymous

By JESSIKA TRANCIK

Electrifying transportation is one of the most promising ways to significantly cut greenhouse gas emissions from vehicles, but so-called range anxiety — concern about being stranded with an uncharged car battery — remains a barrier to electric vehicle adoption. Is range anxiety justified given current cars and charging infrastructure?

It’s a question my research group and I addressed in a paper published in Nature Energy, by taking a close look at this problem with a new model.

Batteries for Off-Grid Homes

Batteries are still expensive, so homeowners are unlikely to be disconnecting from the grid anytime soon

Posted on Jul 29 2016 by Martin Holladay

Is solar electricity cheap or expensive? There are two parallel stories circulating these days. One version of the story — the older of the two — is that electricity from a photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. (PVPhotovoltaics. Generation of electricity directly from sunlight. A photovoltaic (PV) cell has no moving parts; electrons are energized by sunlight and result in current flow.) array is more expensive than grid power, and that adding batteries makes PV even more expensive.

The newer tale, oft-repeated on GBAGreenBuildingAdvisor.com, is that PV is cheap and getting cheaper, and that any utility that tries to limit PV installations is doomed to failure — because homeowners who are disgruntled by a PV-hostile utility will choose to install batteries, cutting the cord to the grid.

After Lithium-Ion, What?

When will we have better batteries than lithium-ion for gadgets, electric vehicles, and energy storage for the grid?

Posted on Jul 27 2015 by Matthieu DuBarry and Arnaud Devie

Many of us would be hard-pressed to spend a day without using a lithium-ion battery, the technology that powers our portable electronics. And with electric vehicles (EVs) and energy storage for the power grid around the corner, their future of this battery technology appears pretty bright.

New Life for Old Electric Vehicle Batteries

Nissan and General Motors find a way to give batteries a second life, solving two problems at once

Posted on Jun 22 2015 by Scott Gibson

The batteries that power electric vehicles like the Nissan Leaf and Chevy Volt still have as much as 80 percent of their storage capacity when they're replaced, and figuring out what to do with them has been a headache for manufacturers.

These used batteries are no longer strong enough to run a vehicle, but unlike the cars themselves, they are difficult to take apart and recycle. Now both Nissan and General Motors have come up with a solution that not only solves, or at least delays, the recycling issue but offers businesses a way of reducing their power bills.

A First in New England: Utility-Scale Battery Storage

The system in Maine will reduce loads on the grid during summer peaks avoid the cost of new transmission lines

Posted on Jun 12 2015 by Scott Gibson

Three shipping containers parked in the industrial park of this midcoast Maine community contain 600 batteries that collectively have enough capacity to power 100 houses for a day. The batteries are part of a comprehensive pilot program designed to prevent transmission lines in the area from overloading in summer.

According to an article in the Portland Press Herald, the battery array is the first utility-scale storage system for electricity in New England.

Are Solar-Plus-Battery Systems Coming to a Neighborhood Near You?

SolarCity thinks batteries will be critical to the widespread use of solar, but for now very few residential customers have the chance to try them

Posted on Jun 5 2014 by Scott Gibson

Solar-plus-battery systems that combine photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow. panels and lithium-ion batteries are helping a number of commercial electricity customers cut their power bills, but any widespread spillover to the residential side of the market looks to be some time away.

Two solar installers, SolarCity, and SunPower, are offering the systems to residential customers, yet the numbers in the pilot programs are very modest.

Solar Energy Can Make the Grid More Resilient

When coupled with battery storage, renewable sources of energy can help smooth out spikes in electrical demand and brief power interruptions

Posted on Dec 5 2013 by Alex Wilson

In my blog last week, I reported on The Navy Yard in Philadelphia, a remarkable 1,200-acre business campus with 300 companies employing 10,000 people — with as many as 35,000 employees projected eventually. What had attracted me to the facility while I was in town for a conference, was an innovative demonstration that’s been launched showing how solar-electric (photovoltaic(PV) Generation of electricity directly from sunlight. A photovoltaic cell has no moving parts; electrons are energized by sunlight and result in current flow.) systems with battery back-up and smart controls can help to create a more resilient power grid.
