Electrovaya announced a new product of portable energy storage systems called Transportable Energy Storage System (TESS).

500 kW of power and 800 kWh of energy, TESS will be developed and introduced on the market in Q2 2016 for the purposes of increased grid efficiency and resiliency during outages.

Electrovaya is gaining momentum in ESS as their lithium-ion cells are rated for 9,000 1C/1C (100% DOD) and still hold about 75% capacity (30 Ah in 40 Ah cells).

The system will be designed to meet Con Edison’s requirements and ultimately be utilized for grid support and as an alternative to the standard mobile diesel systems. TESS will operate using advanced lithium ion batteries.”

“The project received support through the New York State Energy Research and Development Authority’s (NYSERDA) Smart Grid Program as part of Governor Cuomo’s Reforming the Energy Vision (REV), a comprehensive energy strategy to build a clean, resilient and affordable energy system for all New Yorkers.”

“Con Edison currently uses portable diesel generators for dispatchable, temporary on-site energy needs. Energy storage technology provides a much cleaner method of portable energy availability.”

Dr. Rajshekar DasGupta, VP Business Development said:

“We are very excited to begin the project with Con Edison and NYSERDA to deliver a highly innovative take on an energy storage system. Con Edison worked closely with Electrovaya to develop the specifications for the TESS and ensure that it has the right performance characteristics to meet their usage objective. We believe the TESS will give the right mix of resilience, reliability, performance and cost effectiveness for the application. The project builds upon Electrovaya’s experience with lithium ion energy storage systems and will utilize our latest technologies, including the new cell developments and ceramic separator technology from our Germany subsidiary.”

Margarett Jolly, Con Edison Director of Research and Development commented:

“Con Edison is pleased to be working with Electrovaya on this innovative project. We believe that Electrovaya’s TESS will have tremendous potential to strengthen our network and ultimately improve our service to our customers. We worked closely with Electrovaya for some time to develop the specification for this project and are excited about seeing the results during field trials.”

  1. Nick says:

    The cycle life doesn’t seem as nearly as good as lithium titanate.

    I wonder why they went with a different chemistry?

    1. Speculawyer says:

      lithium titanate is probably too expensive.

      1. Glenn says:

        A disadvantage of lithium-titanate batteries is that they have a lower inherent voltage (2.4 V), which leads to a lower energy density than conventional lithium-ion battery technologies (which have an inherent voltage of 3.7 V)

        1. Speculawyer says:

          Sounds like a nice home battery then.

    2. Paul says:

      NMC has the highest energy density. Titinate has hi energy and low density. To get the power from NMC you use parallel cell stacks… Titinate Hi energy long life. Now Electrovaya has hi energy density and long life…

  2. Three Electrics says:

    800 kWh is a joke. At these energies, they could perhaps be used to keep the lights on at headquarters for a little while without the inconvenience of having to use a diesel generator.

    1. Cavaron says:

      That would be enough for 40 households with 5 persons each for 24h, at least where I live.

    2. mike w. says:

      Article does say it is intended to replace a mobile diesel generator.

    3. sven says:

      ConEd is the utility for New York City. These battery storage systems, like diesel generators, will be used to provide electricity for local outages (ie transformer blows) that last less then 24 hours. They will also be used to replace stinky diesel generators for temporary events like Fashion Week, which set up giant tents for runway shows that last only one week.

  3. Marcus says:

    Titanate has about a third of the energy density; it would make for a very bulky unit indeed. Besides at an expected one cycle/day 9000 cycles is 25+ years; high cost is another problem for titanate, it only makes sense at very high c rates and/or extreme cycle numbers

  4. SJC says:

    Discharging 500 kW for an hour over 9000 cycles with 80% capacity remaining is not bad for building peak shaving.
