No matter what side of the fence you are on, everyone is agreed that electricity companies will be very different in a few years’ time. Change is inevitable of course and we need look no further than the business world to see that sustainable businesses adapt and prosper, leaving others in their wake.[read more]

Will Batteries Be a Defining Technology Achievement in this Decade?

March 4, 2014 by Christine Hertzog

The 20th century was a time of extraordinary growth and change. In the first half of that century, relatively new technologies like electricity and telecommunications indelibly altered every aspect of life. In the latter half of the 20th century, computers radically reshaped work and play.[read more]

DoE and Energy Storage

Grid-scale energy storage system prices have to come down, not just the cost of the actual storage components. At the same time, the value of storage has to be redefined in the energy landscape, according to a new report by the U.S. Department of Energy.[read more]

New Federal Agency Renewable Energy Target Overlooks the Importance of Electricity Storage

December 10, 2013 by James Greenberger

On the three-dimensional grid of the 21st Century, energy efficiency is not just about increasing the absolute amount of renewable energy generated and decreasing the amount of energy consumed. It is about managing the entire electricity grid, in all of its dimensions.[read more]

Rethinking the Energetic Cost of Electricity Storage

December 3, 2013 by James Greenberger

The simple answer to Charles Barnhart’s proposition, that you wouldn’t spend a $100 on a safe to store a $10 watch, is: yes you would—if the $10 watch costs $200 to replace. That is the analysis that California has done and that other jurisdictions in the United States and around the world are doing.[read more]

Renewable Energy Barriers Fall With New FERC Order

California's Energy Mandate

The state of California has recently implemented a mandate for energy storage in 2020. However, taking a closer look at the specific details of the mandate shows that the actual outcomes of this mandate are, in fact, very uncertain.[read more]

Transformative Solar Energy Storage Policy for California

California Solar Storage

The thing I like about California Governor Jerry Brown is he seems to be able to look a problem squarely in the face and simply say ” How do we solve this?”. He knuckles down very hard by all accounts. Case in point? His proposed new solar storage policy.[read more]

Four New Rulings Will Boost Solar Energy and Storage in California

October 17, 2013 by Stephen Lacey

Emerging Role of Energy Storage

 

After a series of financial setbacks and exhaustive regulatory deliberations, energy storage fed by renewables is set to earn a scalable role due largely to a new mandate in California and market rules and incentives in the PJM Interconnection. But will it? Can it?[read more]

Will Energy Storage Save the Grid?

September 30, 2013 by James Greenberger

It has long been assumed that the rise of distributed generation is a good thing for the grid and for the electricity storage business, but both assumptions should be questioned. For a grid largely based on distributed generation will have benefits, it will also have drawbacks.[read more]

Renewables and Energy Storage Issues

 

Everyone knows energy storage is the key to unlocking renewable energy’s full potential, right? Well, not always. Utility-scale batteries make sense for storage from large solar power systems, but not wind farms, according to the journal Energy & Environmental Science.[read more]
