A California public utility has brought the largest battery energy storage in North America online. Funded partially by federal stimulus funds, Southern California Edison’s Tehachapi Wind Energy Storage Project is designed to demonstrate the effectiveness of large-scale battery storage systems.
Southern California Edison Company is the largest electricity supply company in Southern California. As part of the U.S. Department of Energy’s implementation of the American Recovery and Reinvestment Act of 2009, the utility won funding to develop a major battery energy storage system (or BESS). The Tehachapi Wind Energy Storage project consists of an array of lithium-ion batteries capable of storing 32 megawatt-hours, deliverable as an 8 megawatt stream of energy for 4 hours. The LG Chem batteries rely on the same lithium-ion cells installed in battery packs for General Motors’ Chevrolet Volt electric vehicle, and feature 608,832 individual battery cells arrayed in 10,872 battery modules and 604 battery racks. Along with two 4MW/4.5MVA smart inverters, the project will be housed in a 6,300 square foot facility sited at SCE’s existing Monolith substation.
For more than 100 years, the U.S. power system relied on fossil-fueled power plants to meet our growing energy demand. Now, clean energy resources like renewables are quickly changing our energy mix. But what happens when the sun isn’t shining or the wind isn’t blowing? What about when power demand momentarily outpaces supply? That’s where… Keep reading →

Modeled after the Defense Advanced Research Projects Agency (DARPA) — the agency that brought us the GPS, the stealth fighter and computer networking — the Energy Department’s Advanced Research Projects Agency-Energy (ARPA-E) funds… Keep reading →
Innovative or just silly? You decide. But clearly innovations in the energy space are penetrating mainstream thinking. The relationship between saving energy and saving money has advanced in recent years, with inventors focusing efforts on the next big (or super small) energy breakthrough. Check out the devices below and use the comment section to let… Keep reading →
WASHINGTON: Budget crunch be damned, the Defense Department’s effort to get more energy-efficient is still in business, said the assistant secretary in charge. Even without the free-flowing supplemental funds and the flexibility of the “rapid equipping” initiatives that allowed for speedy spending at the height of Afghanistan and Iraq, the Pentagon is still trying to reduce its… Keep reading →
Energy storage is an exciting space for researchers, investors and established energy industry players alike because as technology advances and costs come down the potential for truly disruptive – and highly lucrative – innovation feels almost within grasp. The ability to cheaply and reliably store and dispatch utility-scale volumes of electricity will alter existing power… Keep reading →
Quick Take: A decade after its original publication, a coalition of industry organizations has updated its Electricity Storage Handbook. The document was produced in collaboration by Sandia National Laboratory, the Electric Power Research Institute (EPRI), the U.S. Department of Energy (DOE) and the National Rural Electric Cooperative Association (NRECA). Although focused on transmission and distribution… Keep reading →
Scientists at the Lawrence Berkley National Lab discovered a way to create a virus battery, for lack of a better term. The technology “produces electricity by using the piezoelectric properties of a biological material,” according to the US Department of Energy website. You can read more about the science and technical aspects below, but the… Keep reading →
Last week luxury electric sports car company Tesla Motors announced a major charging station build out, but a Cornell University researcher has cautioned that further scrutiny may be required. Two of the greatest barriers EVs need to overcome in order to compete with gasoline vehicles are range and charging time. You can fill your gas… Keep reading →
