A VPP is a grid of varied sources of energy to work as a single large power plant. Rather than depending on large power plants, VPPs utilize small energy sources such as home solar panels and batteries. Smart technology regulates the flow of energy so that electricity consumption is maximized.

These systems balance the supply and demand of energy. If the energy is required, the VPP can release additional power. In case of excess energy, it can store it or sell it to the grid. This reduces customers’ electric bills.

How VPPs Save People Money

Maximizing Solar and Battery Storage

Users of VPPs get the most out of their solar panels and batteries. One company, Evergen, asserts that houses using their smart energy system save up to 26% on electricity bills. The system uses battery power when the price of electricity is high and charges when the price is low.

Getting Paid for Extra Energy

VPPs enable customers to feed back excess power to the grid. Most energy providers compensate such power in the form of feed-in tariffs. In South Australia, the SA VPP scheme saves individuals up to $551 annually by trading stored power during peak periods.

Reducing the Cost of Power Stations

Legacy power plants and network upgrades are very costly. VPPs eliminate the demand for costly new facilities when they produce energy efficiently. This prevents the cost of electricity from increasing.

Promoting Competition in the Market

VPPs sell power in the National Electricity Market (NEM), which lowers the price. According to the Australian Energy Market Commission, VPPs can make energy cheaper, saving Australians AU$834 million by 2050.

Saving Energy When It Is Least Costly

VPPs also operate demand response schemes. These schemes modify power consumption according to the real-time prices. That is, individuals consume more power during low prices and less power at high prices, resulting in low bills.

Example: South Australia’s Virtual Power Plant

The SA VPP is a prime example of an Australian VPP. It’s a government-South Australia and Tesla collaborative project. The VPP unites thousands of households with solar panels and Tesla Powerwall batteries to form a grid of energy sharing.

The SA VPP has numerous advantages. It saves individuals money on their electricity bills, stabilizes the power network, and cuts fossil fuel demand. It also exports excess energy to the NEM, lowering the price of electricity for all.

Challenges of VPPs

Though VPPs possess many advantages, they also have their disadvantages. Batteries and solar panels are expensive to install at first, but government subsidies cut down on the expense. Other than that, governments and energy companies will have to collaborate so that VPPs are within reach for all.

Government Support for VPPs

The Australian government is promoting people to be part of VPP schemes. Schemes such as the South Australian Home Battery Scheme and the Victorian Solar Homes Program provide rebates to offset the cost of batteries.

VPP programs are also being funded by the Australian Renewable Energy Agency (ARENA). These programs will enhance the utilization of VPPs and energy savings in Australia.

The Future of VPPs in Australia

As technology advances, VPPs will only improve. Artificial intelligence, smart energy systems, and advanced energy trading devices will make energy even more accessible.

Battery storage is also becoming less expensive, and more individuals will be able to afford to participate in VPPs. This will lead to a robust energy network, reduced electricity bills, and a cleaner environment.
