Czech households are now contributing to the stability of the national electricity grid through a new platform developed by Delta Green. The initiative allows homes equipped with solar panels and battery storage systems to provide performance balancing services, previously reserved for industrial facilities. Depending on real-time grid needs, households can supply or draw electricity for short periods, typically a few minutes several times per day. The project is being implemented in cooperation with the national transmission system operator ČEPS and energy company Nano Energies. In recent weeks, the partners certified a one-megawatt aggregation block composed entirely of households, marking the first such unit in the Czech Republic. Jan Hicl, co-owner of Delta Green, noted that while the concept of flexible electricity consumption is unfamiliar to most people, early adopters have quickly adapted. The service is designed not to interfere with everyday household operations, and connected users may see substantial cost reductions. For a typical four-person household, annual energy expenses could be reduced by up to one-third, with potential monthly savings of around CZK 1,000. Martin Kašák, Director of the Energy Market Industry at ČEPS, emphasised the growing importance of aggregators in maintaining grid reliability. By broadening the pool of participants to include households, the market for performance balancing services becomes more competitive, which could help reduce costs. The platform uses real-time monitoring to manage electricity use and coordinate the aggregated response of multiple households. These flexibility aggregators consolidate energy contributions from smaller producers or consumers and offer them as standardised products in energy markets or directly for grid balancing. The new model represents a shift in how energy flexibility is sourced and used across the Czech electricity system. Source: CTK
