Denmark rolls out hourly meter reading

Electricity company Eniig this month started phasing in hourly meter readings as part of a flexible billing project. The plan is for all its customers to be on the system by the end of 2020.
 
Consumers' electricity consumption will be read using remote sensors and settled hour by hour. Users will not be able to choose when they are converted; this will be decided by the networking company.
 
The network informs Eniig Energi when a consumer is ready for a flex settlement. Some may find they have to replace their electricity meters before they can be switched.
 
Users who are flex-billed can choose to settle according to the prices in the electricity market hour by hour. They will be able to move some of their electricity consumption to periods with a lower electricity price, or for periods where, for example, there is a lot of power from wind turbines or solar cells.
 
This also means that they have the option of affecting their electricity bill, for example by letting their dishwasher, washing machine and tumble dryer run at night and during the weekend. This lets them move electricity consumption from the expensive hours to the cheap ones.
 
How much a user saves depends on how much they spend. Based on Eniig calculations, users can save up to a few hundred DKK annually. This will be a little bit less for those with new energy efficient electrical appliances rather than older products.
 
It is difficult to calculate exactly how this will affect an electricity bill. It depends on when during the day and the week that an individual uses power. Generally, the price is most expensive during the daytime on weekdays and cheapest at night and during the weekend.
 
In periods where there is a lot of wind and where a large part of the electricity production comes from the wind turbines, electricity prices are typically low. In addition, the production of solar cells is important, as is how much power Eniig can get from Norway and Sweden’s hydroelectric power.
