Is it mandatory for electricity consumption in a multi-family residence to be billed individually based on the utility company’s main meter, or can the landlord also rent out the apartments on a flat-rate basis that includes both electricity and heat?
The SFOE’s guide on self-consumption states:“The ‘ CSC ’ is considered a single end consumer (Art. 18(1) EnG). The distribution network operator (DSO) therefore measures the consumption and feed-in of the entire ‘ CSC.’ The distribution network operator also measures the production of systems with a capacity exceeding 30 kVA. CSC must take care of everything that occurs within the CSC —that is, behind the grid connection point—such as measuring the individual consumption of the parties involved at CSC , allocating the total electricity costs, issuing and validating certificates of origin (HKN), and billing.”
What formula is used to allocate PV electricity to individual customers in the billing system at CSC ?
The data is averaged and billed in 15-minute intervals. smart-me automatically allocates solar power to tenants. A tenant always pays for the electricity they have actually consumed. If a tenant uses more solar power, they are billed for more solar power.
Metering Concept CSC
As a general rule, the metering concept remains unchanged within the CSC . This means that all consumers must be metered (apartments, common areas, etc.). In addition, PV production must always be metered.
Do you recommend measuring the balance counter or calculating it virtually?
To take full advantage of all features and optimally implement an " CSC " using our technology, we recommend integrating the balance meter (utility company and HAK metering) as well.
- For calculating virtual rates (HT/NT/Solar) – Serves as a control measurement and is strongly recommended when virtual rates are used.
- For calculating and visualizing the degree of self-sufficiency, etc., because some visualizations and calculations do not work without the balance sheet measurement.
- Self-consumption optimization is achieved through "if-then" actions of the net energy meter.
- Dynamic load management (HAK monitoring) for e-mobility is achieved through balance measurement.
- In conclusion: Experience has shown that it may not be possible to use all of the newer features if the measurement concept isn't properly set up.
How can the highest average power (kW) consumed during a 15-minute period in a month be measured and billed? Power billing for large customers.
The highest average power consumption over a 15-minute period during the month—also known as “peak load”—is often measured and billed in the energy industry to reflect the costs of supplying electricity or energy during peak times. With “ smart-me ” billing, you can bill for such peak loads. You can configure this in the web portal under “Billing” – “Configuration.”
