This could be the biggest sign yet that the battery revolution is here – the washington post electricity and circuits physics

The California Inland Empire Utility Agency’s solar panels, located at three of the Agency’s recycled water facilities and IERCF, generate 3.5 MW of clean solar power and will reduce electrical costs at its facilities gas and supply — the single largest component of IEUA’s operating budget.

Meet Advanced Microgrid Solutions, based in San Francisco and headed by former Arnold Schwarzenegger chief of staff and California Public Utilities commissioner Susan Kennedy. The company specializes in the creation of “ hybrid electric buildings,” office or infrastructure buildings that contain large battery systems that can simultaneously reduce energy costs for users and owners, and also help strengthen the larger grid by running on batteries at key electricity 1 7 pdf times, and thus not requiring grid power. Thus, AMS is selling to businesses and utilities simultaneously, and with a recently announced deal with SunEdison to supply 50 megawatts of energy storage to major California utility Southern California Edison, there is clearly a market for this kind of service.

But in many ways, AMS’s latest deal is even more intriguing — it is now announcing that it will supply and operate batteries for a very large California customer la gasolina mp3, the Inland Empire Utilities Agency. It’s a large municipal water treatment and distribution agency serving the San Bernardino County region of California, where it has 850,000 customers.

Inland Empire is very advanced in trying electricity png to switch its operations, which include multiple plants for recycling and desalting water, to clean energy. That includes 3.5 megawatts of solar capacity at its facilities, another 1 megawatt of wind, and a 2.8-megawatt bio-gas fuel cell system. The agency says the latter is the largest of its kind in the world.

The batteries involved are about as large as a vehicle parking space and are made by Tesla — the company calls them “Powerpacks.” The installation should be able to cut Inland Empire’s peak electricity demand by 14 percent, leading to an electricity cost savings of 5 to 10 percent, the partners announced. In this equation, AMS does not just supply the batteries, it also operates the system and helps the utility figure out how to maximize its savings.

According to AMS, the total battery installations will provide 3.5 megawatts of power, a figure that denotes how much electricity they can discharge continuously (a megawatt gas stoichiometry worksheet answers is a million watts). However, what’s equally crucial is how long a battery can operate. In this case it would be a little more than 2 hours, giving the system an energy rating of 7.5 or 8 megawatt hours, Kennedy says.

There are multiple benefits, agrees Inland Empire’s Grindstaff, to having the batteries. Besides reducing peak charges gas zeta costa rica, they can provide backup power in the event of an outage. Plus, they will also literally help the agency fight the California drought. That’s because the agency recycles a great deal of waste water, and while that activity is critical in a time of scarce water supplies, it also takes energy — which, in turn, costs money.

In fact, Kennedy argues that the project sits squarely at the gas unlimited houston texas water-energy “nexus” — a concept describing the strong relationship between heating, providing and reusing water and consuming energy. The California Energy Commission says that water and energy are therefore “inextricably connected,” and as water demand rises with population growth, so will electricity demand (and greenhouse gas emissions, unless that demand is serviced with renewables).

The news comes in a big and arguably breakout year for batteries and energy storage overall. On top of Tesla’s massively watched announcement of a new line of home and larger scale battery products, there are gas and water socialism a growing number of installations overall, especially at the larger or utility scale, according to research by GTM Research’s Manghani. Earlier this year, he forecast that 2015 would see a record 220 megawatts’ worth of storage installations.

The company earlier this month announced a contract with the Irvine Company, a real estate developer and planner, to install batteries in 24 separate buildings, an offering that would not only allow for electricity powerpoint template demand charge reductions but also provide Southern California Edison with 10 megawatts of potential demand reduction at peak times (between 40 and 60 megawatt hours, according to Kennedy). AMS says that’s enough electricity to power 10,000 California homes. The company also has a memorandum of understanding with Shell North America to install 20 megawatts of batteries in its California facilities.

Overall, the battery business is booming but also very new, and we don’t know where AMS’s approach will lead. But one thing is clear — major companies and electricity nightcore utilities are thinking more and more about storage and sometimes going as far as to add it, both to back up their facilities and systems, but also to time when they use self-generated power so as to save themselves money.
