Fast-Acting Flexibility at a Premium for a Green-Powered Western Grid

November 2, 2015 by Jeff St. John

Flexibility in the Western Grid

The Western U.S. power grid could use a lot more 15-minute energy resources to help it bring more solar and wind power on-line. And that's a job that batteries, demand response, and quick-start generators can do a lot better than big fossil-fuel-fired power plants.[read more]

Senate Bill Would Create America's First National Energy Storage Target

May 28, 2015 by Stephen Lacey

Energy Storage and Utilities

Under the bill, called the Energy Storage and Deployment Act of 2015, large retail electric utilities would need to meet at least 1 percent of their peak demand from storage by 2021. By the end of 2024, they'd need to meet at least 2 percent of peak load with storage[read more]


Cost of Batteries for Electric Vehicles Falling More Rapidly than Projected

April 13, 2015 by Jesse Jenkins

Costs for Electric Vehicle Batteries

The cost of battery packs for electric vehicles has fallen more rapidly than was previously projected, with market leading firms in 2014 producing batteries at ~$300 per kilowatt-hour of storage capacity, on par with market projections for 2020.[read more]

Greensmith to Deploy Aqueous, Lithium-Ion and Flow Batteries for Grid Storage

September 3, 2014 by Eric Wesoff


As the energy storage market develops and shakes out, it's worth keeping an eye on Greensmith. The startup is a software developer and system integrator that has attracted investment, personnel and a growing roster of turnkey energy storage projects.[read more]

Con Ed Looks to Batteries, Microgrids, and Efficiency to Delay $1B Substation Build

July 26, 2014 by Katherine Tweed

Consolidated Edison is taking a new approach to delivering reliable power that is as radical as the gentrification sweeping New York’s outer boroughs. Con Ed filed a proposal for a Brooklyn/Queens Demand Management Program, or BQDM, that it hopes can defer the cost of building a $1 billion substation.[read more]

Heres a Way to Get Utilities to Embrace Solar and Batteries: Let Them Own the Inverter

July 8, 2014 by Stephen Lacey

Utilities own a wide range of devices on the transmission and distribution grid to manage power quality. But there's a power control device that may be much more familiar to the hundreds of thousands of American homeowners with solar on their roofs: inverters. Should utilities own those too?[read more]

Battery Technology: Of the Past, but Lifeblood for the Future

March 26, 2014 by John Steller

Batteries and the Future

Before the massive electrical grids and power lines that our current infrastructure relies so heavily upon, batteries were how we made electricity. As batteries advanced, so did our technology. From lead-acid to lithium ion, battery technologies dominate the majority our our appliances, and amenities.[read more]

Lab Uses Lightning Bolt to Charge Smartphone

October 3, 2013 by Christina Nunez

Sometimes our dependency on battery-charging devices seems ironic, considering the abundance of energy around us that is being generated every day by sources as mundane as the human hand, footsteps, and lightning, which strikes the Earth dozens of times per second.[read more]

After a prolonged development program and costly production delays, Boeing started delivering its latest state-of-the-art airplane just 15 months ago, three years behind schedule. Although the company has a lucrative backlog of nearly 800 787s on order, worth roughly $200 billion in revenues, production rates have been limited, as only 50 units have been delivered in a little over a year.[read more]

Researchers Discover ‘Crushed’ Silicon Increases Battery Life

November 5, 2012 by Nino Marchetti

Normally, when a scientist spends a good portion of their life in a lab, trying to engineer a technological breakthrough, the last they want is to see that work destroyed. But as researchers at Rice University recently discovered, crushing their previous work can sometimes be the only way to make progress.A Rice team has been trying...[read more]


Will Cheap Energy Storage Come to Coal and Nuclear's Rescue?

March 22, 2012 by Jesse Jenkins

Everyone knows that the development of low-cost, large-scale electricity storage technologies will be critical to the future of wind and solar energy--or at least everyone who reads The Energy Collective knows that! The ability to cheaply store electricity when the sun is shining or the wind is blowing and use it later when...[read more]
