|Sadales tīkls AS will take care of reading the electricity meter. The smart electricity meter sends readings to Sadales tīkls AS automatically|
|An opportunity to follow one’s electricity consumption on the Internet|
|After a message has been received confirming that the provision of benefits has entered into force, households and companies can easily follow their electricity consumption on the site of the electricity trader or on the customer site of Sadales tīkls AS www.e-st.lv|
|A possibility to reduce the bill if electricity use habits are changed|
|After installation of the smart electricity meter and receipt of information regarding entering into force of benefits, everybody can easily follow electricity consumption on the site of its electricity trader or the customer site of Sadales tīkls AS www.e-st.lv. Hourly consumption is displayed and it can be compared over various periods. Information is presented in the form of a comprehensive graph. One’s electricity use habits can be analysed in this way and they can also be modified in order to reduce the total monthly electricity consumption.|
|Faster restoration of electricity supply in cases of electricity cuts|
|In case of faults the automated system will determine if there is a problem in the internal power network or a power line of the distribution system operator, thus allowing much faster identification and elimination of the problem|
In order for the smart electricity meter to be able to provide all the benefits available to you, it should be connected to the power grid. For example, during the winter period when your summer cottage is not used, electricity supply should be disconnected by maintaining the meter connected (by using fuses or an within your ownership limits). If the meter is not connected to the power grid, it will not read the data remotely (it will only record them at the site) and it will not be possible to issue the bill for consumed electricity based on the actual consumption. In this case, even if electricity was not actually consumed at the site, the bill for consumed electricity will be issued based on the principle of equal payments according to the mean consumption.
The benefits provided by smart electricity meters are now appreciated by owners of more than 280 thousand sites.
Some of the observations that provide inspiration to use to move forward:
Sadales tīkls AS ensures power supply to over 1 million customer locations throughout Latvia. To keep record of the electricity consumed, the company uses electromechanical or induction electricity meters and electronic meters. In order to provide the customers with more reliable and modern distribution services of a higher quality, in 2014 Sadales tīkls AS started upgrading the outdated pool of electricity meters and implementing smart electricity meters.
|Functionality of a smart electricity meter|
|Smart metering solution|
|Consumption data is read from the smart electricity meters using a remote reading system. Data transfer via low voltage power lines and data networks has been selected as a primary communication technology for remote data readout from smart meters. The introduction of smart metering provides tangible benefits for all parties involved – the distribution system operator, customers and electricity traders. One of the most significant advantages is the availability of current data on energy consumption and the ability to remotely control the meter that will significantly change the usual procedure for obtaining data, settling payments and organizing inspections of the meters. Due to the availability of data, the electricity trader will have an opportunity to make bills in accordance with the actual consumption of electricity by the customer, as well as to offer the customer the option to make payments at a variable electricity price set at the exchange. The traders will have a possibility to reduce risks and provide the customers with a lower price, and the customers will get a chance to save money by monitoring their power consumption depending on the fluctuations of the electricity price at the exchange. In addition, smart meters enable the traders to develop a range of specific products for the customers. Furthermore, the customer can quickly receive and analyze data on hourly electricity consumption. The experience gained in pilot projects implemented so far demonstrates that the availability of detailed information on the consumption of electricity allows customers to use power in a more energy-efficient way and reduce their electricity consumption. The availability of accurate data on energy consumption enables Sadales tīkls AS to improve the quality of customer service, while reducing the costs of the system operator, as smart meters virtually require no checking on site. The system operator can obtain information about the current load in the low voltage network, which allows for a more objective assessment of the transformer load, and this, in turn, provides a more optimal planning of infrastructure investments.|
