Yesterday, Saturday 13th, in South Australia the Tesla battery at Hornsdale Power Reserve was paid AU$1,000/MWh (USD$790/MWh) to absorb excess electricity from the power grid. The battery owners will later be able to sell this energy also.

The battery has become famous for coming online in under 100 days after an Elon Musk Twitter bet and later reacting to a crashed coal plants in milliseconds.

Florida Representative Holly Raschein has sponsored a new bill in the Florida Legislature to fund a $10 million pilot program installing solar panels and energy storage at strategic public facilities to keep them up and running during critical events and natural disasters.

The program would start on July 1, and run for a single year. The Florida Solar Energy Center (FSEC) will administer and report on the outcomes, with potential expansion.

On January 3rd, New York governor Andrew Cuomo delivered a state energy storage target of 1500MW via the private market by 2025 and has put up $260 million in state money to help drive the investment.

In the annual “State of the State” address, varying proposals  – from combating MS-13, to cleaning up the Hudson River, to expanding clean energy jobs – were delivered to start the new year. The energy storage target delivered seems to be an extension or culmination of prior state legislation requiring targets be set.

The California Independent System Operator (CAISO) – the group that manages 80% of the electricity used in California – has begun showing utility-scale batteries charging and discharging into the power grid via their website.

By resolution, due to a natural gas emergency, the State of California requested large-scale battery based energy storage projects be attached to the grid at the end of 2016, early 2017. Now we get to watch the systems – some that we covered – do their job.

A vanadium/mining industry PR firm has visited the site of an in development 200MW/800MWh vanadium flow battery in Dalian, China and noted that site work is ongoing. They also stated that most of the product that will fill the site – the vanadium batteries – is already built in the manufacturer’s nearby factory.

This battery is currently the largest planned chemical battery in the world, and part of a Chinese government investment to spur the technology.

NY Governor Cuomo has signed into law a bill (AB 6571) directing the state’s Public Service Commission to develop an Energy Storage Deployment Program, including a storage procurement target for 2030.

New York now becomes the fourth US state to have energy storage targets/mandates. California and Oregon have a mandate in place, while Massachusetts has set a law that dictates a target to be finalized shortly. South Australia turned on the world’s largest lithium ion battery just yesterday.

In Tesla’s Q3 2017 earnings report, they gave an update on their ‘Tesla Energy’ division. They highlighted being on track to meet the 100-day deployment deadline of the 100MW/129MWh energy storage project for South Australia. Mention was made of the work being done in Puerto Rico in the aftermath of Hurricane Maria – ‘solar panels, Powerpacks and hundreds of PowerWalls.’

Additionally, Tesla – at multiple points – pointed toward a future of more revenue from energy generation and storage. 11% of the quarter’s revenue came from the Tesla Energy division.

Electrical grid complexity has increased immensely. Recently, weather damage and intermittent renewable energy production have increased the dynamics that must be managed in a large power grid. In order to address that, the Dutch company Alfen is currently field testing their new ‘cellular smart grid’ solution in Lelystad, the Netherlands.

They have developed a combination of energy storage and finely tuned algorithms to help make electrical grids more resilient and to reduce their downtime.
