The basis of a virtual power plant is that an electricity grid virtually connects hundreds, even thousands, of homes. These homes may already have solar and energy storage facilities installed. A virtual power plant can help use them collectively to act as a backup. It can be used when demand soars or to take excess power off the grid in need.

A Virtual Power Plant (VPP) is a network of decentralized, medium-scale power-generating units such as wind farms, solar parks, and combined-heat-and-power units, as well as flexible power consumers and storage systems. VPPs can perform a wide range of activities depending on the market context. 

The goal is to connect dispersed energy resources such as wind farms, solar parks, and Combined Heat and Power (CHP) units so companies may observe, forecast, optimize, sell, and trade them. The capability of various distributed energy resources (DERs) dispersed throughout the network is aggregated by a virtual power plant (VPP).

Virtual power plants can also provide ancillary services to grid operators. So they can assist in the maintenance of grid stability. Frequency regulation, load following, and providing operating reserve are examples of ancillary services. The primary use of these services is to keep the instantaneous balance of electrical supply and demand in place. In response to varying levels of consumer demand, power plants providing ancillary services must respond to grid operator signals to increase or decrease the load on the order of seconds to minutes.

Furthermore, it also establishes the requirements for incorporating renewable energy sources into markets. Individual small plants are typically unable to offer their flexibility on the power exchanges or balance services. This is due to either their generation profile’s excessive variation or the fact that they fall below the marketplaces’ minimum bid size. A VPP can provide the same service and redundancy by combining the power of multiple units, and as a result, trade on the same markets as large central power plants or industrial users.

Virtual Power Plant Market Size

In 2021, the global virtual power plant market was valued at $0.88 billion and is expected to increase and reach $6.47 billion by 2028. Analysts anticipate the market to grow at an approximate CAGR of 32.8% during the forecast period 2022-2028. Factors such as the widespread adoption of novel technologies like cloud platforms and IoT applications in the power sector will have a significant effect on market growth. (Source)(Source)

Tesla’s VPP in South Australia, maybe the biggest, exemplifies how these virtual power plants can benefit society. Australia was once known for its exorbitant electricity costs and shaky grid. That’s when Elon Musk and The South Australian government made a deal to install Powerwalls and solar panels in 50,000 homes, many of which belonged to low-income families. (Source)

There are other advantages of virtual power plants, but it comes with some challenges too. The article discusses them in detail.

Virtual Power Plant Advantages

Contributing to the Creation of a More Stable Grid – To operate safely and efficiently, all power networks require energy generation and electricity to be balanced. If either side of this equation changes or varies, it can result in power outages and blackouts. Along with the major power plants, there are smaller, more agile, and flexible power plants (often gas) that can ramp up and down quickly. These plants operate in the Frequency Control Ancillary Services (FCAS) markets.

Plants in this market are sometimes paid to stand-by’ and be ready to turn on at a moment’s notice. VPPs can function in this sector since they can quickly discharge or charge power from the grid.

Reducing Emissions and Load Shifting – VPPs enable real-time movement of residential, commercial, and industrial loads based on price signals to provide demand-side management services to grid operators. When done correctly, this will minimize the demand for high-emitting power plants while lowering carbon emissions. (Source)(Source)

Virtual Power Plant Challenges

Inadequate Infrastructure and Huge Costs – Advanced communication technologies, such as an energy management system (EMS), which enables the observation, management, and control of different energy devices, must be included in the high-quality infrastructure required for the building of VPP. Integrating current technologies and processes into a VPP requires significant investment and a highly qualified workforce. As a result, inadequate infrastructure and the increased costs associated with new technologies are projected to limit market growth over the forecasted period.

Stabilizing Virtual Power Plants – Some countries have already detected a negative impact on grid stability and electrical quality. The grid is gradually becoming an active distribution network as various alternative energy sources, particularly renewable ones, are developed. In this situation, procuring the stability provided by ancillary services becomes highly significant. The providers of virtual power plants (VPPs) encounter a challenging situation because they want to gain from the shift to renewable energy while retaining their capacity to provide the service accurately and cost-effectively.

Conclusion

Swell Energy, a home energy startup, recently got a funding amount of $120 million led by Softbank and Greenback. The funding will help Swell Energy develop 600 MWh of VPPs by deploying and aggregating 26,000 energy storage systems in homes and businesses across the United States. 

Its CEO, Suleman Khan, previously worked at Tesla. He left the company in 2015 to co-found the cleantech firm. He admitted that in the earlier days of the startup. 

According to Khan, there was little talk about home batteries, let alone virtual power plants among utility companies.

They are currently seeing a high demand from utility companies to establish virtual power plants in places like California, Hawaii, and the Northeast of the United States.

“We’re seeing this interesting flip. It used to be that we were riding the solar coat-tail. Wherever there were solar panels, we would step in and offer batteries. Now we’re seeing batteries pull in demand for solar. And as we get to 2024, I think you will see more utilities in the Southeast and Northwest adopt virtual power plants. It’s like an imperfect storm, where potential outages and a capacity shortage have come together to create this massive need for new dispatchable energy services.”, said Suleman Khan, CEO of Swell Energy. (Source)

Additionally, there is a growing demand for dispatchable energy in the Midwest, Southeast, and Texas. There is a high demand for home batteries worldwide, even though there has not been much demand for solar in the past. We expect multiple collaborations between tech giants and industry leaders in the coming years. It’ll be interesting to see the startups making a place for themselves amidst these collaborations.
