Clean energy, reducing residential costs, and powering data centers

[Old Rocks]

Reducing residential electricity costs and powering data centers may actually reside in the homes themselves. Solar with battery backup, at no cost to the homeowner, and with a reduction in electrical costs may well be the least costly way to pay for peaker power and the data centers power.

This is not a new idea, and has already been tested successfully in South Australia;

South Australia Home Power Plant (SA VPP) Program​

South Australia’s Virtual Power Plant (SA VPP) is the state’s largest network of home solar and battery systems, designed to deliver affordable, reliable, and renewable electricity to participating households Energy & Mining.

What is the SA VPP?​

A Virtual Power Plant is a network of distributed energy resources — in this case, homes with solar panels and Tesla Powerwall batteries — that work together like a single power station. The VPP operator uses smart software to charge or discharge batteries and trade energy on the National Energy Market, helping to stabilise the grid, reduce blackout risks, and lower electricity costs Energy & Mining+1.

Who Can Join?​

• SA Housing Trust tenants in eligible homes are automatically considered for the program. If your home is suitable, you’ll receive information from the SA Government and AGL on how to join energy.gov.au.
• Not all homes can have solar or a battery installed — suitability is assessed by AGL SA Housing Authority.
• Community battery systems are also being rolled out for homes that cannot support solar or a battery, storing excess grid energy for later use SA Housing Authority.

Benefits for Participants​

• Lowest residential electricity rate in SA for all energy used, regardless of source energylocalsretail.com.au.
• Sustainable electricity from renewable sources.
• Power backup during outages via Tesla Powerwall energylocalsretail.com.au.
• Smart meter installed at no cost (if eligible) energylocalsretail.com.au.
• Energy savings and reduced emissions through efficiency upgrades in some properties SA Housing Authority.

How It Works​

1. Install solar and/or Tesla Powerwall at your home (AGL may install at no cost if eligible) energylocalsretail.com.au.
2. Store excess solar energy in the battery during the day.
3. Share stored energy with the grid when demand is high, helping the state’s energy network www.saenergysolarandbattery.au.
4. Receive bill credits or savings while still powering your home first www.saenergysolarandbattery.au.

Rates​

• Anytime plan: ~25% less than the reference price, with extra savings for Direct Debit/CentrePay payments.
• Anytime with controlled load: ~25% less, with further savings for payment method.
• Example: Lowest cost ~$1,725/year (inc GST) for average usage energylocalsretail.com.au.

How to Join​

• If you live in an eligible SA Housing Trust home, you’ll be contacted by AGL or the SA Government energy.gov.au.
• For other homeowners, you can contact AGL’s SA VPP centre on 1800 135 178 or email HousingSAVPP@sa.gov.au to check eligibility SA Housing Authority.

In short: The SA VPP turns your home into part of a large-scale renewable energy network, giving you lower bills, backup power, and a role in supporting South Australia’s clean energy future.

Current Power Output of South Australia’s VPP​

South Australia’s Virtual Power Plant (VPP) — now owned by AGL Energy after Tesla’s 2025 acquisition — is built around about 7,460 Tesla Powerwall home batteries and roughly 25 MW of linked rooftop solar systems RenewEconomy+1.

While the exact instantaneous power output is not publicly disclosed in real time, the VPP’s installed capacity is 37 MW of battery storage and 25 MW of solar generation RenewEconomy+1. This means the combined system can potentially deliver up to around 62 MW of total power (solar + storage) at peak times, depending on weather and grid demand.

In practice, the VPP’s output varies throughout the day:

• Solar generation peaks during midday, when rooftop PV systems produce their maximum output.
• Battery storage can ramp up or down to balance supply and demand, providing peak shaving, frequency support, and export credits.
• AGL has reported that the VPP has generated significant revenue and contributed to grid stability by responding to frequency deviations and pricing signals PV Tech.

Summary:

• Installed capacity: ~37 MW storage + ~25 MW solar
• Potential peak output: ~62 MW (solar + storage)
• Actual output: Variable, depending on weather, demand, and grid needs

If you need the exact current moment’s power output, that would require live data from the Australian Energy Market Operator (AEMO) or AGL’s energy management system, as it changes continuously.
