Decreasing motivation to feed-in in Germany
More self-consumption
Less production & feed-in
Reduced positive impact on network & climate
Feed-in remuneration
8.5-12.3 Cent/KWh
Production costs 10-14 Cent/KWh
Electricity price 29

Assumption
Consumers are willing to pay a higher price for renewable energy provided by local producers.
Feed-in of producer Anna is blockchainified
Her smart meter measures the feed-in supply and publishes it to the blockchain
Anna feeds in and receives usual feed-in remuneration
Anna monitors stats of her contributed energy on her mobile
ProducerAnna
Consumer Tom supports a local grid
Tom consumes the energy of his energy provider as usual
He donates a monetary supplement to the local grid in form of cryptocurrency
His supplement is transferred to a pay-in addressmanaged by the local grids smart contract
ConsumerTom
The smart contract of a local grid
The smart contract distributes the total pay-in of the consumers in proportion to the provided energy to the payout addresses of the producers
contract LocalGrid {
struct Producer {
address addr;
uint amount; // produced KWh since last payout
}
mapping (uint => Producer) producers;
...
address public balance;
uint public nextPayoutTime;
uint public donationPeriodInDays = 30;
...
function addConsumerDonation(uint amount) { ... }
function receiveProduction(uint producerId, uint amount) { ... }
function payout() { ... }
}
Consumers
• Contribution to climate protection
• Support local producers
• Flexible
• Transparent
• Easy
Producers
• Monetary supplement
• Minimal overhead costs
Energy System
• Minimally invasive
• No new infrastructures
Benefit
Figures for Germany
0,5% German households
donate 13% on top of monthly electricity bill
(11 €)
5% of German PV plants
become local grid producer
5% = 354 €yearly surplus for producer
