Storage systems have become so affordable and reliable that the commission said utilities should be deploying them as part of their "normal course of business."

New York PSC directs utilities to deploy 2 or more grid-scale storage projects
...According to the order, by the end of next year each individual utility must have energy storage projects "deployed and operating at no fewer than two separate distribution substations or feeders.” Additionally, the projects should address at least two grid functions, such as boosting generating capacity of a substation or reducing peak load when demand is highest.

Additionally, the order requires that utilities push the development of distributed energy resources, and directs utilities to do more to create online portals to provide information to help DER developers. Those improvements must include advances to hosting capacity maps and similar information. ...

More on the Tesla/ South Australia storage offer.  A Twitter negotiation:

Elon Musk: @mcannonbrookes Tesla will get the system installed and working 100 days from contract signature or it is free. That serious enough for you?

Mike Cannon-Brooks: @elonmusk legend! ☀️ You’re on mate. Give me 7 days to try sort out politics & funding. DM me a quote for approx 100MW cost - mates rates!

Elon Musk: @mcannonbrookes $250/kWh at the pack level for 100MWh+ systems. Tesla is moving to fixed and open pricing and terms for all products.

Shails: @elonmusk is this global price?

Elon Musk: @shails Yes, but shipping, taxes/tariffs and installation labor vary by country, as those costs are beyond our control

The Great Australia/Tesla Energy Story continues:

Previously: Government party treasurer lovingly waves a lump of coal ("We're not afraid of it!") during parliament session, as record heat and wildfires cause power blackouts.

Aussie entrepreneur Mike Cannon-Brookes tweets Elon Musk, asking if he's serious about Tesla Energy's newly-announced ability to install 100MWh of battery storage in 100 days.

Musk:  @mcannonbrookes Tesla will get the system installed and working 100 days from contract signature or it is free. That serious enough for you?

Mike Cannon-Brookes:  @elonmusk legend! ☀️ You’re on mate. Give me 7 days to try sort out politics & funding....


The latest:
Musk: @mcannonbrookes Just spoke with @JayWeatherill, Premier of South Australia. Very impressed. Govt is clearly committed to a smart, quick solution.

Australian Prime Minister Malcolm Turnbull (known for his love of the Australian coal industry) has hour-long phone call with Musk.  (Perhaps he was simply happy not to get yelled at!  ;) )    PM's coal-loving party tries to cover by saying:  we knew about Musk's offer all along; we were just waiting for the right moment.

Mike Cannon-Brookes: @elonmusk @JayWeatherill not to push my luck… big $ commitments pouring in. Are 10 x 100MWh installs (grid distributed) possible or crazy?

 Postscript:

Elon Musk: Just wanted to write a note of appreciation to the many Australians who came out in support of the battery plan, especially @mcannonbrookes
    .@mcannonbrookes Can only happen with your support, and working closely with key govt and utility leaders who are strongly committed to trying new approaches

Tesla wasn't the first to suggest battery storage was part of the solution to Australia's power problems. But they were the first to capture the imagination of the public and the politicians.

Billionaire tweets signal end of the road for fossil fuel dinosaurs
...Musk’s Twitter exchange with Cannon-Brookes triggered such a response on social media that he soon had both South Australia premier Jay Weatherill and prime minister Malcolm Turnbull on the phone, and had changed the debate about Australia’s energy future – something that thousands of submissions and endless reports had failed to do.

With any luck, this should be the wake up call needed to shake Australia’s politicians, regulators and media commentators from their delusion that fossil fuels are the only answer to Australia’s so-called energy crisis.

This assumption has been ruthlessly exploited by the “traditional” energy industry to call for a curb on new wind and solar farms, for the building of new “clean coal” plants and for the opening of coal seam gas reserves across the country – all in the name of so-called cheap, reliable and clean energy.

Of course, Tesla is not the first company to make the now obvious point that the solution relies not in new coal and gas plants, but in wind, solar and battery storage. But it helps to get media and public attention when two youngish, fashionable billionaires decide they can fix the country’s energy “crisis” in a Twitter conversation....

Inventor of the Li-Ion battery develops new solid-state battery technology with higher energy density and greater lifecycle charge/discharge potential. 

this paper is free for those registered on the site.

Lithium-Ion Battery Inventor Introduces New Technology for Fast-Charging, Noncombustible Batteries
Feb. 28, 2017

Another advantage is that the battery cells can be made from earth-friendly materials.

“The glass electrolytes allow for the substitution of low-cost sodium for lithium. Sodium is extracted from seawater that is widely available,” Braga said.

Goodenough and Braga are continuing to advance their battery-related research and are working on several patents. In the short term, they hope to work with battery makers to develop and test their new materials in electric vehicles and energy storage devices.

Wonderful news. Do you think they'll make it to realistic production before or after fusion power?

Article didn't say much about timescale to actual product.

This research is supported by UT Austin, but there are no grants associated with this work. The UT Austin Office of Technology Commercialization is actively negotiating license agreements with multiple companies engaged in a variety of battery-related industry segments.

Sounds quite hopeful but who knows?

The researchers demonstrated that their new battery cells have at least three times as much energy density as today’s lithium-ion batteries.

Also sounds very good. Is that per weight or volume? If by weight/volume how does it affect volume/weight?

OTOH How often do we hear of some dramatic improvement and how often does that turn out to be an illusion?

The short video in this article dissects a Tesla battery cell and examines what's inside.  Their testing resulted in 95% capacity remaining after 500 cycles of the Tesla cell, compared with only 70% capacity using Panasonic's "off the shelf" formulation.

The Tesla numbers on degradation due to recharge cycles fits with announced claims for Powerwall/Powerpack. 5000 cycles / 15 years

Residual Value: Electric Batteries vs. Internal Combustion Engine Vehicles

https://ark-invest.com/research/ev-batteries-value

Extract
One of the chief concerns about Electric Vehicles (EVs) – battery degradation – seems to be misplaced: ARK’s research suggests that EV batteries will retain substantial value after reaching the end of their in-vehicle lives. Utilities are in constant demand for energy storage products. In fact, if electric utilities were to pay $15,000 per battery, the battery alone in a 10-year-old TeslaTSLA would retain more value than an entire vehicle powered by an internal combustion engine (ICE).
