Why We Need Smart Homes

According to a study by Solar Energy UK, as global efforts are being made to achieve net zero carbon emissions, governmental strategies are stimulating a shift towards electric vehicles (EVs). This transition increases electricity demand, calling for a boost in renewable generation. This spike in demand, especially during peak usage periods, imposes a significant strain on electricity systems. For example, mass EV charging in commuter areas or high generation with low demand during favorable weather conditions could disrupt the grid balance. The solution to such challenges lies in promoting flexibility across the power system. Flexibility includes the ability to adjust electricity usage, storage, and grid export based on demand and supply.

The promotion of widespread flexibility can stave off expensive grid reinforcements, subsequently reducing the burden of energy bills on consumers as these upgrade costs are usually passed down. Enhanced flexibility also allows for new renewable sources to be connected to the grid and prevents shutting down renewable generators when generation surpasses demand. Additionally, the flexibility of power systems plays a key role in decreasing carbon emissions, as it reduces the need to resort to high-carbon fossil-fuel generators during peak times. This practice can help avoid unintentional power outages, disconnects, or unnecessary expensive infrastructure investments.

The need for grid balance through flexibility is rising, underscoring the growing significance and market value of flexible power sources. However, not all flexibility service providers are low-carbon, such as gas power stations, which are carbon-intensive and polluting. As an alternative, incentivizing flexibility from low-carbon smart homes could help balance the electricity grid with greener technologies, introduce more renewables to the system, and reduce network operation costs. While households can potentially play a significant role in fostering a more flexible electricity grid, currently only a small fraction engage in practices such as Time of Use Tariffs (TOUTs) or participate in local flexibility tenders due to policy and regulatory barriers. The adoption of smart homes can help overcome these challenges, making them a pivotal part of the journey towards achieving net zero.
