GE is gaining momentum it its new approach to lithium-ion energy storage systems.

The company recently add its third and up to date largest 30 MW ESS order for the Imperial Irrigation District in Southern California. The first two were Con Edison Development in California and Convergent Energy + Power in Ontario.

There is no info about energy, but combined power output from the three ordered ESS will be 39 MW.

For GE, energy storage system will also generate a lot of revenue from selling different stuff: GE’s Mark* VI plant controls, GE Brilliance* MW inverters, GE Prolec transformers, medium-voltage switchgear and advanced lithium ion batteries housed in a GE purpose-built enclosure.

Construction of 30 MW ESS will begin next year and is expected to end in the third quarter of 2016.

“Continuing its mission to deliver comprehensive energy storage solutions, GE (NYSE:GE) today announced it will provide Coachella Energy Storage Partners (CESP) with a 30-MW battery energy storage system as part of CESP’s supply contract with the Imperial Irrigation District (IID). Representing GE’s largest energy storage project to date, the plant will be located in California’s Imperial Valley, approximately 100 miles east of San Diego. The facility will aid grid flexibility and increase reliability on the IID network by providing solar ramping, frequency regulation, power balancing and black start capability for an adjacent gas turbine.”

Mike Abatti, president of CESP said:

“We chose GE as the energy storage system provider for this project because they supplied the most comprehensive solution at a competitive price. GE is well-positioned to serve the needs of the project and will remain a stable, reliable technology provider as the energy storage industry evolves.”

Ziad Alaywan, P.E., a California energy veteran and president & CEO of ZGlobal Inc. commented:

“This project is a game changer to the energy industry and will be one of the largest battery storage plants in the western United States. We are confident in GE’s technology and look forward to a successful project.”

Anne McEntee, president and CEO of GE’s renewable energy business remarked:

“While we always strive to provide competitive pricing, what really differentiates GE is the fact that we listen to our customers and help craft a customized energy storage strategy. We focus on full system performance rather than individual component pieces, allowing customers to match power production with demand in real time and utilize grid assets more efficiently.”

GE is a great company. They do it all in the energy business: Wind turbines, gas turbines, combined cycle, and now battery storage.

I wonder where they are getting the batteries (or did I miss that)


The battery maker/supplier wasn’t mentioned in GM’s press release, which apparently is the source for this article.


39MW at 10C rate is 3900kWh

But if it delivers 2 hrs of backup at that rate for the incentive program, then it would require about 80,000kWh of capacity.

It is decent size, but NOT something to make or break the busines.

GE should look at EOS EnergyStorage

Three Electrics

Battery storage is great for the first few hours of energy storage–efficient, if not cheap. If more is desired, power to gas systems pencil out better because storage costs do not increase linearly with energy, as they do with batteries. Compressed air and hydrogen are the leading contenders. The former is cheap but the latter can be transported.


Compressed air need some way to heat the air as it expands. Natural gas is often used for that, which is a poor choice for the long term.

(If you don’t heat the expanding air it gets so cold it causes problems.)

Ambulator There’s no way to make the process completely non-adiabatic, but if you maintain the gas at ambient temperature during compression by cooling it with water, the energy can then be removed from the water to reheat the expanding gas. This has been theorized many times but Lightsail is currently the “name” company executing the concept at significant scale. Again, like all conversion and storage and recovery round trips it is imperfect, but seems to be “good enough”.

My only complaint with Lightsail is the overwrought TED talk sanctimony that seems to go along with much of the green industry. It’s a freaking air compression and storage system, but it is described as Earth-saving. Shades of Shai Agassi…



Go pencil out the roundtrip efficiency of hydrogen. Electrolysis losses -> storage losses -> fuel cell losses, plus pumping losses all through the chain. Go ahead. I DARE you.
