Bank of LiPo batts to make power grid smart

Bank of 1,440 lithium-ion batteries to make power grid smarter
A bank of lithium-ion batteries big enough to supply about 500 U.S. homes with electricity during a power outage went online today to demonstrate the future of smart grid technologies.

The 5-megawatt battery is a piece of a larger, government-backed $178 million research project in the Pacific Northwest to make the electric grid more efficient and friendly to additional loads of renewable energy such as wind and solar, which fluctuate depending on the weather and time of day.

The battery itself consists of 1,440 individual modules that are "just like electric vehicle batteries," Elaina Medina, a spokeswoman for Portland General Electric in Salem, Ore., where the battery bank is installed, explained to NBC News.

The company has partnered with the Department of Energy's Pacific Northwest National Laboratory to use the battery in a range of smart grid tests, including as a storage system for renewable energy that is produced when demand is low.

For example, Oregon's Biglow Canyon Wind Farm is most productive at night when everyone is asleep. The power will be stored in the battery and then released when "everyone's getting up, getting ready to go to work in the morning and we've got more demand on the system," Medina said.

The utility also plans to use the battery as a backup power supply during blackouts. It will turn on the instant an outage occurs on the system, keeping everyone on the local grid humming along. "What that means for customers is they won't see any blip," Medina noted.

The battery should last long enough for backup diesel generators to fire up and begin serving as a power source until the grid is ultimately restored.

Awesome indeed

My vision of the future involves smaller scale versions of this system in each home. Your EV(s) in your garage connect with a bi-directional grid-tie to whatever small solar/wind/hydro etc system that you've got handy to make power with, even if it's just 500w of solar or whatever (and at ~$0.85/watt, it's really very reasonable to have even 2-3kW on your roof these days). Anytime your cells are making power, you're grid tied and distributing it to your neighborhood grid, or storing it in your EV's batteries while they are plugged in. During times you don't have wind or solar etc, your power comes from the EV batteries in the neighborhood etc. Neighborhoods could even have transmission lines to feed other neighborhoods or factories etc that consume more power than they produce.

The concept of a central power grid, and all the super cheap dirty non-renewable fuel sources many of them use will slowly fade into a thing of the past as solar prices drop and grid tie inverters improve in capabilities and EV batteries become common in each home and parking stall etc.

All awesome steps in the right direction that I love to see!

All good ideas, but the utilities do not like this. As soon as their profits start dropping they will be lobbying like crazy to try and stop clean energy in your home. Clean energy puts them out of business. A big battle is ahead.

Well, no, its Google's vision as they originated the concept and plowed millions & millions into it to bring it into being. Anyway, its any one's who makes the investment. Distributed generation with energy storage, at home, with excess capacity to sell onto a smart-grid market. I'm doing that too! :mrgreen:

FOR IMMEDIATE RELEASE

ENERDEL’S 5 MEGAWATT ENERGY STORAGE SYSTEM COMES ONLINE AS PART OF PORTLAND GENERAL ELECTRIC’S SALEM SMART POWER PROJECT

Solution Ties into PGE’s Electric Power Grid to Support Renewable Integration, Back-up, and Peak Shaving Needs. Energy reliability is increased while diminishing environmental impact through reduced emissions.

INDIANAPOLIS (June 3, 2013) – EnerDel, Inc., a leading manufacturer of advanced Lithium-ion batteries and energy storage systems, has completed the commissioning of a 5MW energy storage system (ESS) used as part of Portland General Electric’s (PGE) Salem Smart Power Project, which is part of the Pacific Northwest Smart Grid Demonstration Project. EnerDel’s solution is comprised of five (5) 1MW systems featuring EnerDel’s SP90-590 that were installed, tested and commissioned on-site in Salem, Oregon over the last several months.

“EnerDel is excited to be working with PGE to demonstrate how customers can benefit from the use of smart grid systems and technologies that incorporate energy storage for renewable resources, back-up power and peak shaving,” stated EnerDel CEO David Roberts. “In collaboration with the other partners involved with the project, we support PGE’s efforts to demonstrate the value that is afforded by smart grid solutions. Ultimately, grid security and reliability increases while decreasing energy costs and promoting a cleaner environment. PGE’s decision to integrate renewable energy sources into the grid using EnerDel Li-Ion technology demonstrates forward thinking and affirms the adaptability and safety of this technology.”

EnerDel’s ESS includes 1,440 rack-mounted lithium-ion battery modules monitored by an advanced battery management system to support a 5MW inverter array consisting of twenty (20) 250kW/62.5kWhr channels rated at 600VDC. Each channel will contain an independently-operated battery management system connected to a 250kW inverter. This configuration delivers a high level of control, flexibility and safety.

The ESS is part of the larger PGE power system comprised of five large breakers that bring power in and out of the building allowing the inverters to change the electricity from alternating current (AC) to direct current (DC) during the charging cycle. The direct current electricity is stored in EnerDel’s ESS to be used during peak demand periods, or, as back-up power when there is a loss of utility supply. The same power system and inverters convert the clean DC to AC as the grid demands. This reserve electricity can be stored for several weeks at a time and drawn from to support the needs of more than 3500 residential and business customers thereby allowing PGE adequate time to make repairs and restore the grid.

The project will improve system reliability, support renewable resource integration and decrease peak-price risk. PGE expects the project to be operational for a minimum of 10 years.

About EnerDel

________________________________
The above was copied and pasted from a release sent to me from EnerDel. Looks like a 1.25 MWh battery pack and 4C rated. Not relating directly to this project but of interest to me; EnerDel has designed the product and system with intent to re-purpose EV and HEV batteries after end of useful life on vehicles. Once an EV battery has degraded over say a 10 year period of use down to 80% of capacity, it would be returned to EnerDel for the residual. They would service the battery, repackage it and sell it to utilities for grid storage where the reduced energy density is less of a factor than in vehicles. The utilities would see a better $/kWh for tolerating a bit larger battery. The EV owner would also see a reduced cost of ownership. And it will keep the batteries out of the landfills for a longer period, perhaps increasing service life 3 or 4 fold.

I made a post way back, on the Sphere, that, NYC is on a battery startup system, every morning. There is NO way for the grid to carry all the startup between 8-9AM. Trailer loads of A123 batteries are being used, and, it's also why most big cities never turn off all the lights in the buildings. It will wreak havoc on the grid.

This is where A123 got their start, not in Ev's.

Seems like a job for very large format cells? Not ~20Ah?
