Mieterstrom, IoT & Blockchain (EN)

  1. 1. Next Big Thing AG 1 Energy distribution: Networking and decentralization Mieterstrom Internet of Things Blockchain BDEW Workshop 30.03.2017 Michael Maria Bommer Next Big Thing AG
  2. 2. Next Big Thing AG Next Big Thing AG 2 Current State: Energiewende Impact of arising renewables: unpredictable and intermittent supply 1 The prosumer phenomenon2 Grid fragmentation: central network structure vs. cellular approach 3 Interconnectivity of flexible grid structure4
  3. 3. Next Big Thing AG Next Big Thing AG 3 Inefficiencies → Mieterstrom is the first step: Matching the locally produced solar energy with local consumption within an apartment building. High volatile load on distribution networks: Energy has traditionally been produced to meet demand, in the context of renewable energy, demand and supply don’t always match. 1 Energy Transmission: Transferring energy from where it’s produced to where it is needed. 2 Ideal Scenario: Consumption of power when available Smart Grids
  4. 4. Next Big Thing AG Next Big Thing AG 4 What is Mieterstrom? → On-site delivery of PV or cogeneration electricity, saving fixed price components apart from EEG apportionment: → Concept: a part of the electricity from eligible plant is sold to a tenant / commercial user behind “a counter” while saving charges and taxes Concept → PV / cogeneration → Customer Plant Operation (grid feeding) → Power Supply (additional power) → Measurement Functions The next step of decentralisation of the grid
  5. 5. Next Big Thing AG Next Big Thing AG 5 Why Mieterstrom? → Energy supply (PV+other energy sources), measurement and invoicing from one service provider → Service similar to energy suppliers for housing cooperatives and property owners → Tenants have a reduced electricity price (distribution margin, network charges, concession fee, grid apportionment, electricity tax) → Mieter haben einen reduzierten Strompreis (Vertriebsmarge, Netzentgelte, Konzessionabgabe, Netzumlagen, Stromsteuer) Incentives for Customers → Other players might enter the market piggybacking on the Mieterstrom concept, but they are unable to provide the entire service alone → New opportunity to help housing associations to manage the new systems -> service Incentives for Energy Providers
  6. 6. Next Big Thing AG Next Big Thing AG 6 IoT & Blockchain: tech development → Reduce capital expenditure → Manage demand → Increase renewable capacity → Lower maintenance costs → Comply with regulations → Enhance customer engagement 2017: IoT is being steadily adopted in Smart Grid, but the solutions are fragmented and not connected 2020: Further adoption of IoT and initial consolidation around separate functions in a smart grid, no consolidation between actors IoT → Cryptocurrencies → Peer-to-peer lending → Decentralised energy-transaction and supply system → Decentralised energy-transaction and supply system, supply of solar energy to developing countries → Smart devices → Solar power certificates 2017: All blockchain solutions are in the prototyping phase 2020: First blockchain-based transaction models Blockchain → Shifting the roles of the energy market players
  7. 7. Next Big Thing AG Next Big Thing AG 7 1. The role performed by meter operators would change: they would no longer have to collect and record data themselves, as all consumption and transaction data would be exchanged automatically and accurately through blockchain technology (smart contracts). 2. Distribution system operators would also receive the information on transactions they require to charge their network costs to customers from the blockchain. 3. Transmission system operators would no longer require data for clearing purposes, as all transactions would be executed in real time and settled only on the basis of actual consumption. Blockchain-based transaction model All electricity delivered to the networks can be clearly attributed to individual customers in small time units (down to time windows of only a few minutes) Current market roles Market roles under a decentralised transaction model (blockchain)
  8. 8. Next Big Thing AG Next Big Thing AG 8 Technology challenges: 
 IoT & Blockchain 1. Complexity of cyber-physical system of energy generation (digital blockchain does not work) - two parallel systems - physical energy transfer and data/ cryptocurrency digitally 2. Existing gap between IoT and blockchain 3. Security as an overall challenge for smart grid (on the hardware, firmware and connectivity layers) 4. Real time data processing and micro-transactions on the blockchain
  9. 9. Next Big Thing AG Next Big Thing AG 9 NR-GEN Vision IoT Device TEE Blockchain & Cloud Payment routing Automated transaction Marketplace Data storage, balance sheet management Data collection → Date analysis → Trade & Invoicing Trading operations
  10. 10. Next Big Thing AG Next Big Thing AG 10 Secure Smart Contracts Enabling Components 1. Secure communication protocol: MQTTS (MQTT + TLS) 2. Embedded secure IoT-TEE /Trusted Execution Environment/ (eg. Secure chip) 3. IoT device is not hackable (physical/cyber) 4. Secure Smart contracts: - Independent from any blockchain technology - Usage of RTA /Real Time attestation/ - sSC is enabled to communicate its own safety status Outcome: 1. Toolset for building own customized smart contracts 2. Own marketplace with log in effect
  11. 11. Next Big Thing AG Next Big Thing AG 11 Use Cases: IoT + Blockchain + Mieterstrom 1. Various players within the value chain, e.g. decentral energy providers and energy buyers, communicate and trade with each other through their IoT devices, using a testified Smart Contract (tSC). 2. The tSC allows them to define their specific terms (e.g. selling requirements and buying conditions such as billing, time frame and ID). 3. Usage of an online marketplace to autonomously closed between the two trading IoT devices (e.g. solar panel and e-car). Role of the energy company – management of smart contracts and serving customized services based on the Traditional Processes Processes in a blockchain-based system → Role of the energy company – management of smart contracts and serving customized services.
