The End of Subsidy-Driven PV: How System-Level Optimization Turns Homes into Market Participants

GridX and the Future of Renewable Energy for Prosumers

GridX is positioning itself as a leader in renewable energy accessibility, aiming to make it affordable for all. The company has over 240,000 connected assets that activate 40 megawatt hours of flexibility daily, targeting utilities and energy retailers amid regulatory changes in Germany. A significant shift occurs in 2027 when new photovoltaic installations will no longer receive feed-in tariffs, prompting prosumers to explore innovative business models for sustainability. Prosumers currently receive about €370 annually from subsidies, potentially decreasing with a switch to direct marketing. To mitigate potential revenue losses and enhance profitability, GridX proposes aggregating prosumer households into a trading pool that can access various market opportunities. The implementation of dynamic grid fees and bidirectional charging technology is also being explored to optimize energy usage and stabilize the grid. The upcoming Agnes reforms in 2029 may necessitate equitable cost-sharing measures among photovoltaic generators to support grid expansion. Overall, adapting to these changes is critical for prosumers' success in a competitive energy landscape.

Talk of session: HEMS & BEMS: Intelligent Energy Management from Homes to Buildings

Home and Building Energy Management Systems (HEMS & BEMS) are becoming essential tools for installers and system integrators delivering smart, energy-efficient buildings. From PV, EV charging and storage to heating, automation and grid interaction, modern EMS solutions must be easy to integrate, interoperable and future-ready. This session highlights practical solutions, standards and real-world implementations shaping the next generation of smart homes and buildings.

For more than two decades, Norway has been steadily building a marketplace for electric transport. Having started out with inexpensive short-range electric cars and household charging sockets, Norway has now moved to mass-market solutions where fast charging (DC) and grid balancing (AC) plays an ever more vital role. With more than 1,000,000 electric cars and over 10,000 fast chargers in a relatively small market, Norway offers a rare early view of large-scale electrification. Over the past decade, electric cars have seen substantial improvements, which is now making it easier for new markets to advance electrification. At the same time, Norway has to deal with challenges years before other markets do. Yet despite different starting points, we can see that most markets are facing the same core challenges. From grid-smart charging strategies to innovative business models, there are excellent examples of best practices emerging elsewhere in Europe. What will the next thing in electrification be, both in mature and in emerging markets? And what will be possible when the right people and companies come together, sharing knowledge, solving common problems and accelerating the shift to cleaner mobility?
