Tesla is launching phase 3 of its massive virtual power plant in South Australia and confirmed that soon almost 4,000 homes with Powerwalls and solar will be connected to the system.

A virtual power plant consists of connecting several small distributed energy assets, like residential solar panel systems and home battery packs, and use them together to provide larger grid services.

With its Powerwall being a popular home energy storage system, Tesla has been an early adopter of the concept and planned to deploy it on a large scale in South Australia.

The project’s origin story is interesting.

It came around after Elon Musk visited South Australia following the launch of its giant battery system in the state.

Musk gave an interview during which he was informed of the significant hardship that Australia’s high electricity prices are putting on low-income families.

The region suffers from a very unstable grid and electricity costs are so high that some families have to decide between keeping the lights on or going hungry.

Visibly affected by the issue, Musk vowed that Tesla would “work harder” to help solve the problem.

A few months later, Tesla announced that it reached a deal with the South Australian government to install solar arrays and Powerwalls on up to 50,000 homes.

The deal was jeopardized after a new government was elected in the state a few weeks later, but they have since come around and confirmed that they will be moving forward with Tesla’s initiative as long as it is financed successfully.

A few months later, in July of 2018, Tesla deployed the first 100 Powerwalls with solar for the new virtual power plant and focused on reducing the cost of electricity for low-income households.

By the end of the year, the project moved to its second phase and Tesla started deploying 1,000 more systems as part of the virtual power plant.

While only a fraction of the total planned capacity of the virtual power plant has been deployed, they already started testing some grid services with the current system.

Earlier this year, the Australian Energy Market Operator, the agency behind the project, has released an in-depth insight report on the virtual power plant and it showed promising results to stabilize the grid while lowering electricity costs for participants.

Tesla is now Moving to Phase 3
Robyn Denholm, Tesla’s chairwoman who also happens to be Australian, announced that Tesla is moving to phase 3 of its virtual power plant:

“Tesla is taking the next step towards accelerating Australia’s transition to sustainable energy with the launch of phase three of the South Australia Virtual Power Plant (SA VPP), growing the program towards 50,000 South Australian homes”

Phase 3 will add another 3,000 homes to the system.

Denholm added:

“A growing number of Housing SA homes – soon to be 4000 – as well as private households via the Tesla Energy Plan are connected to the SA VPP and benefiting from the lowest priced electricity rate in the state while also contributing to a more resilient grid.”

Tesla is going to pay $18 million to deploy the battery and solar systems in phase 3.

The households will receive the systems at no cost and will pay for the electricity from them at a rate more than 20% lower than from the grid.

The South Australian government is contributing $10 million along with $8.2 million from the Australian Renewable Energy Agency (ARENA) and a $30 million loan support from the Clean Energy Finance Corporation (CEFC).

The goal remain to eventually have 50,000 homes with Powerwalls and solar connected to the virtual power plant.

Not the direction a Southern State should be taking, IMO. (Covers the southern part of Alabama, as TVA covers the northern part of AL).

At some point will it prove to be counter-productive to stopping Solar? Does the est $9,000 additional in fees over the life of the system actually provide an incentive towards the purchase of a Powerwall or equivalent and get off the grid entirely?

Energy regulators in Alabama voted Tuesday to uphold what critics have dubbed a "sun tax" on people who put solar panels on their homes and businesses across much of the state.

The Alabama Public Service Commission, which regulates the investor-owned Alabama Power Co., not only rejected a petition by the Southern Environmental Law Center to end the company's extra monthly fee for customers with their own solar systems, but raised that fee by 8 percent.

Alabama Power provides electricity to more than 1.4 million customers across the southern two-thirds of the state, including the cities of Birmingham, Montgomery and Mobile.

The Alabama Power solar fee is part of what clean-energy advocates have described as among the most regressive solar power policies in the country. Losing the decision after a two-year legal battle before an administrative law judge and the commission was a blow, said attorney Keith Johnston, who directs the law center's Alabama office.

The utility has been charging a $5 per kilowatt monthly fee. For an average 5-kilowatt rooftop solar system, the fee results in an additional $300 charge per year, or approximately $9,000 over the life of the panels, slashing solar customers' average savings in half, the law center contends.

The new fee will be $5.41 per kilowatt monthly.
