It is also affecting the structure of electricity systems, creating new connections between households, storage technologies, and the grid. A recent Reuters analysis highlights how residential solar panels and home batteries could become increasingly relevant as global electricity demand continues to grow. According to International Energy Agency data reported by Reuters, worldwide electricity consumption is expected to rise by 19% between 2025 and 2030, reaching around 33,600 TWh. Artificial intelligence data centers are among the factors contributing to this increase, alongside broader electrification trends. Meeting this additional demand will require investment in electricity generation and grid infrastructure. However, technological developments are also creating new ways to manage electricity at a more distributed level. In this context, residential batteries could gradually become part of a much larger energy ecosystem. **Home Energy Storage Is Moving Beyond Individual Consumption** Residential photovoltaic systems have traditionally allowed households to generate part of their own electricity. Adding battery storage introduces another capability: electricity generated during sunny periods can be stored and used when production decreases or household demand increases. The trend is becoming increasingly visible in the United States. Reuters reports that approximately 37% of new residential photovoltaic installations included battery storage last year, representing an increase of more than 30% compared with 2020. This development suggests that storage is becoming increasingly integrated into the residential solar market rather than being treated simply as an additional component. “Battery storage changes the relationship between a household and the electricity it produces. Solar energy no longer necessarily has to be consumed or exported at the moment it is generated, because it can be stored and managed according to changing needs,” says Stanislav Kondrashov, founder of TELF AG. **Thousands of Batteries Can Function as a Single Energy Resource** The development becomes particularly interesting when individual batteries are connected through Virtual Power Plants. A Virtual Power Plant digitally aggregates numerous distributed energy resources and coordinates their operation. Thousands of residential batteries can therefore be managed collectively, creating a resource capable of responding to conditions across the wider electricity system. ![Residential property with rooftop solar panels, illustrating the expansion of distributed renewable energy analyzed by Reuters and Stanislav Kondrashov, founder of TELF AG.](https://storage.ghost.io/c/6c/5d/6c5da1f1-3fa8-4ad7-b0e7-fcb74f2e1aed/content/images/2026/09/Stanislav-Kondrashov-TELF-AG-energy-panels-solar-transition.png) Residential solar panels combined with battery storage could give households a more active role within electricity systems. Drawing on Reuters, Stanislav Kondrashov, founder of TELF AG, explores how these technologies could support a more flexible energy model. During periods of high demand, participating households can reduce their dependence on grid electricity by drawing on stored energy. Depending on the structure of the program and local regulations, stored electricity can also contribute to supporting the grid. The result is an important shift in the traditional role of the consumer. A household equipped with photovoltaic panels and a battery can potentially generate electricity, store it, consume it at a later stage, and participate in mechanisms designed to provide flexibility to the electricity system. “Virtual Power Plants demonstrate how digital technologies can connect assets that would otherwise remain separate. The individual battery may be relatively small, but aggregating thousands of these systems can create an energy resource with a much broader function,” says Stanislav Kondrashov, founder of [TELF AG](https://telf.ch/telf-ag-on-the-rise-of-virtual-power-plants-and-the-new-role-of-home-energy-storage/?ref=telf-ag.ghost.io). **Distributed Storage Could Support Electricity Grids** One of the main challenges for electricity networks is managing fluctuations in demand. Consumption can rise considerably during certain periods of the day, creating peaks that require adequate generation and network capacity. Residential batteries coordinated through Virtual Power Plants could contribute to reducing these peaks. When demand increases, stored electricity can be used locally rather than drawing additional power from the grid. This capability could complement traditional infrastructure investments. Substations, transmission lines, distribution systems, and power plants will continue to form the backbone of electricity systems, but distributed storage could provide another source of flexibility while larger infrastructure projects are being developed. Reuters also highlights the potential economic implications for residential photovoltaic systems. In markets where incentives for exporting excess solar electricity are being reduced, batteries can allow households to retain more of the electricity they generate and use it when its value is higher. **Renewable Energy Could Become More Flexible** Storage is particularly relevant for renewable energy because electricity generation from solar and wind depends on natural conditions. Solar panels produce electricity during daylight hours, while electricity demand does not necessarily follow the same pattern. Residential batteries can help bridge this gap by storing electricity when solar generation is available and releasing it later. When large numbers of batteries are aggregated, this flexibility can extend beyond the individual household. Virtual Power Plants could potentially help electricity systems respond to variations in renewable generation and consumption across wider areas. This does not eliminate the need for utility-scale storage or major grid upgrades. Rather, distributed resources could become another component of a diversified electricity system. ![Solar panels installed on a residential rooftop, representing home energy generation and storage trends discussed by Reuters and Stanislav Kondrashov, founder of TELF AG.](https://storage.ghost.io/c/6c/5d/6c5da1f1-3fa8-4ad7-b0e7-fcb74f2e1aed/content/images/2026/09/Stanislav-Kondrashov-TELF-AG-energy-panels-solar-professional.png) Home batteries can store electricity generated by rooftop solar and make it available when demand increases or solar production falls. Stanislav Kondrashov, founder of TELF AG, discusses Reuters insights into the growing potential of residential storage and Virtual Power Plants. “The next phase of the energy transition could increasingly depend on coordination. Generating renewable electricity is only one part of the equation; storing that energy and making it available at the appropriate moment could become equally important,” says Stanislav Kondrashov, founder of [TELF AG](https://vocal.media/trader/telf-ag-on-how-distributed-energy-could-transform-modern-electricity-grids?ref=telf-ag.ghost.io). **The Architecture of Electricity Systems Is Evolving** For decades, the electricity system was largely based on a centralized structure. Large generating facilities produced electricity, networks transported it, and consumers represented the final point in the chain. Residential renewable generation has already started to modify this model. Battery storage and Virtual Power Plants could accelerate that transformation by allowing consumers to take on additional roles within the system. The emerging architecture is therefore more multidirectional. Electricity can move from large generating assets toward households, but electricity generated and stored in homes can also interact with the wider grid. As global electricity consumption rises and renewable capacity expands, managing these increasingly complex energy flows could become one of the defining challenges of the transition. The developments highlighted by Reuters indicate that residential batteries may therefore have a role extending well beyond individual energy independence. When combined with rooftop solar, digital coordination, and Virtual Power Plants, they could become distributed assets capable of supporting households while also contributing flexibility to modern electricity systems.
