Gaelectric announced a partnership with Tesla Motors on energy storage systems in Ireland.

Their first project will be a 1 MW demonstration ESS, integrated with renewable energy sources. Gaelectric is focused on wind power generation and battery storage could be a valuable asset.

Deployment is scheduled for the 2016, but they are already thinking about future projects.

Besides developments and demonstration of ESS, Tesla and Gaelectric also are seeking business opportunities.

“Specifically, exploring opportunities for other Tesla Energy products in residential and commercial applications. Ireland has many compelling features for the commercialisation of the Tesla Energy product range given its scale and ambitious renewable energy targets and favourable regulatory framework. Investigation of other European markets also forms part of the collaboration.
Tesla is amplifying efforts to accelerate the move away from fossil fuels to a sustainable energy future with Tesla batteries, enabling homes, business, and utilities to store sustainable and renewable energy to manage power demand, provide backup power and increase grid resilience.”

Commenting, Brendan McGrath, Gaelectric Group CEO, said:

“We are delighted to be associated with Tesla in introducing its battery systems to Ireland. As a renewable energy group with a pipeline of 500 MW of wind power in Ireland and energy storage projects in Ireland and Europe, Gaelectric has an obvious incentive to drive the adoption of technologies that facilitate the economic dispatch of wind and other renewable sources.”

Commenting, Gaelectric Head of Energy Storage, Keith McGrane, remarked:

“The accelerating pace of storage technology development and its application to how we generate, use and store power is truly astounding. Much of these developments are around incorporating greater amounts of renewable power while protecting the stability of our transmission systems and controlling costs. Tesla is the vanguard for the revolution that is currently underway.”

How have I never heard of these guys!? I better start taking a look.

Compare and contrast with a similar 1MW hydrogen fuel cell storage system in Germany, announced two years ago:

How odd that a large-scale energy storage system is rated in power, rather than storage capacity.

Well, it’s nice that (if it goes as planned) they’ll be able to output 1 MW of power, altho modern power plants average about 100 times that… 100 MW. The more important question is, now long will it be able to output that much power? How many minutes or hours will it last at that level of output?

Three Electrics

Presumably power is the most costly parameter. The system has to be able to store energy at the peak generation rate of the wind farm, but more critically, discharge it over peak grid hours (roughly six hours a day). Therefore the discharge rate will be roughly 4x the charge rate. The amount of storage needed, in kWh, is likely a straightforward computation from peak power: it’s peak * 12 hours.

I suspect that wind farms will not use batteries in this way. A wind farm can roughly predict it’s output 12 to 24 hrs in advance. I am not sure how the grid works in Ireland but I suspect the wind farm will have to garantee a certain output. So if the wind farm thinks it is going to get 100 MW plus or minus 10 MW it will probably only be able to sell 90 MW to the grid if it has a 10 MW battery then it can garantee the 100 MW and so can sell 100 MW of power. It might only need to store the power for as little as a few min so the MWh is fairly irrelevant.

Lensman
I think you’re more likely right here, Chris. From what I know about the economics of large-scale energy storage, just a few minutes of backup power used for “peak shaving” would have a much higher cost/benefit ratio than an installation big enough to hold hours of power. If it was only a relatively small installation, as compared to the daily output of an average power plant, then that would also explain why the power output is so limited. If it’s to be used as a buffer for a wind farm, then again just a few minutes of power would be quite valuable to the power company, as it would smooth out the peaks that happen as the wind picks up and dies down, second by second and minute by minute. In fact, it’s exactly that erratic variability which has limited installation of wind power in many places; too much variability destabilizes the grid. I personally am not convinced that the cost/benefit analysis favors wind power in most of the locations where it’s been built, because wind power output is a very poor match to demand in most areas. But certainly a few minutes’ worth of power storage buffering a wind… Read more »

Power is what utilities have been traditionally interested in. It’s all been about covering those transients. Going forwards I expect that energy storage will become increasingly important.

How do U Pronounce that? l o l

“Gay lek trik”

I thought THAT one was in San Francisco!….:)

The Anglicized pronunciation of Gael is “Gayle”, but throughout most of Ireland it’s closer to “Guale”, with a somewhat soft G.

Gird scale battery energy storage is measured in MWh while battery storage discharge is measured in MW. To compute the cost of storing wind electricity let me suggest my newest paper; “The Levelized Cost (US$/MWh; €/MWh; ILS/MWh) of Storing Wind Electricity on a Grid-Connected, Utility-Scaled (MW) Energy Storage System (ESS)”, which is scheduled for presentation at the 14th World Wind Energy Conference (WWEC), 26-28 October 2015, Jerusalem, Israel. My paper requires nine specifications to compute the LC of any ESS. Capacity (MWh) and power (MW) are only two of the nine specifications. The paper will work for both solar as well as wind and is battery chemistry and technology agnostic. You can get a copy of my paper with an Excel worksheet by backing it on KICKSTARTER at https://goo.gl/9O8iKb

Out of all the “Me Too” battery offerings, the Tesla Powerwall looks the most sexy… 😉

Lensman

Just who are you suggesting Tesla is imitating here?

I know Tesla isn’t the first company to offer a li-ion battery pack for home energy storage, but it certainly looks like they’re the first to attempt to mass produce such a product.

That one is 1 year older: http://www.leclanche.eu/page/technical-details
Scalable up to 3 units, 3,2kWh each.

Yeah, the TiBox just isn’t as sexy as the Powerwall…

1 MW or 1MWh? Some people mix that up…

4,2MWh capacity with 4MW charge rate is already available for electric ferries…

mr. M

Given that Tesla has the 7kWh / 2kW Battery for daily usage. This is likely a 3.5MWh / 1 MW Battery. Maybe even less capacity to enable higher longlivety, because Wind buffer cycles more like hourly instead oft daily.

Just_Chris

I suspect 0.5 MWh and 1 MW, IMO this is most likely a buffer not an energy store, it’ll be used to smooth the output not boost it for a few hours. If you have multiple hours to fill likely you will do it with a gas turbine not a battery. Maybe I am wrong, if you have a weak grid pherhaps you’ll hold enough energy to cover a few hours. This is a trial so it could be configured in any number of ways depending on what they are interested in.

mr. M

This would make sense, but i dont expect Tesla to usw different cells. Therefore i think this is a 3.5 MWh / 1MW storage.

Just_chris
The cells should be more than capable of sustaining a 1C charge/discharge rate. The power wall is configured the way it is because that is what the domestic market needs. In a domestic setting you want to shift energy around, you can use the grid for any big transient loads and the value to the customer is avoiding paying a commercial rates for power. With a wind farm you want to avoid pushing the grid around because they’ll fine you for it, for a wind farm you’ll want to maximize the amount of wind generation you are selling so the battery will be used to stabilize the power output. This would be best done with a higher charge/discharge rate. 2C for a lithium system should be very achievable. I would be very surprised if the bigger systems can’t charge and discharge more rapidly than the domestic systems. They might be limited, and there might be a good reason for it, such as saving money on cooling/heating systems or being able to use a bigger % of the pack but I would have thought that for this type of application the cells would sit between 20-80% SOC and be flipped from… Read more »

At Tesla’s annual shareholder meeting, Elon said that Tesla is increasing the power output of 7kWh Powerwall to 5kW steady and 7kW peak, while keeping pricing the same.

So, you’re telling us hydrogen is even less relevant?

We knew about the power doubling. And the hydrogen.

Will battery storage be cheaper than Beacon Power’s flywheel systems?
