Energy market change Today’s utilities are facing many challenges and a fast -changing market environment Trends Impact Global and Local Climate Virtual Power Plant (VPP) Prosumers Agreements Decentralized ownership structures People produce and consume for renewable energy systems. their own power with PV + Affordable Renewable Future utilities have to connect a storage. Future utilities have to large number of different provide new products energy participants Increasing Volatility Decentralization High penetration of renewables increases volatitlity on the Energy Services production side which affects energy prices Flexibility is King Customers will prefer clean Digitalization and affordable energy Bringing flexibility into services instead of only Data Access production, consumption and kWh the grid will enable attractive Assets like the revenue streams sonnenBatterie or Smart Decarbonization Meters will provide a large amount of data, which can be used for attractive new System Operators business models Decreasing Grid Service Electrification Due to decentralization, Capacities Distribution System Operators (DSOs) will likely gain in Since conventional power plants are importance vs. Transmission disconnected from the grid, grid service System Operators (TSOs) Integrated Energy capacities will decrease while demand increases due to higher volatility 5 sonnen Inc. sonnen-batterie.com

Future energy ecosystem Prosumer, decentralization, digitalization and connectivity radically change the classic ecosystem Classic ecosystem Future energy ecosystem Digitalization & data driven Connectivity Decentralization Smart Meter Prosumer are an integral component Renewables Grid operator Energy as a Increased TSO à DSO service volatility Conventional producers Consumer Customer centric Decarbonization Flexibility Create a Community that intelligently connects, integrates and manage all participants of the future energy 6 ecosystem. sonnen Inc. sonnen-batterie.com

sonnenCommunity The first of its kind digital and decentralized P2P Energy Sharing Community for end customers • Prosumers, producers and consumers form a virtual electricity pool. VPP software aggregating small-scale assets and balancing supply & demand within Community • Residual power needed by members is bought directly from third-party renewable energy producers • If necessary, VPP software uses the Spot Market (Day Ahead or Intraday) to buy or sell residual power • sonnenCommunity gives power a face – sonnen is the first company adding emotional value to the commodity product “power“ giving real transparency Paul in Phoenix • Capture energy transactions and explore the possibilities of secure energy trading 7 sonnen Inc. sonnen-batterie.com
