What is OIRE?

The Energy Market Information Operator (OIRE) is an entity responsible for the implementation, management and administration of the Central Energy Market Information System and the processing of information collected therein for the purpose of carrying out electricity market processes. PSE S.A. assumed the function of OIRE on July 3, 2021.


What is CSIRE?

The Central Energy Market Information System (CSIRE) is an ICT system used to process energy market information for electricity market processes and to exchange information between system users. Its objective is to support the implementation of retail energy market processes – including, primarily, the supplier change process. It will also be a place where metering data from smart meters (collected and transmitted to CSIRE by TSO and DSOs).


What is energy market information?

  • information regarding the metering point (e.g., address, contracted power, tariff group);
  • metering data;
  • information about events recorded by a smart meter;
  • commands received by the smart meter;
  • other information necessary for the supply of electricity.


What are the main objectives of the functioning of CSIRE?

The key objective is to ensure an efficient and secure exchange of information in the electricity market, enabling market participants to fulfill their statutory rights and obligations. Other equally important objectives are:

  • unification and streamlining of electricity market processes, including in particular the electricity supplier change process;
  • improving competitiveness in the electricity market;
  • allowing consumers to access their own energy market information (including metering data) free of charge;
  • providing professional users with free access to selected statistical data;
  • providing data to enable market participants to offer new products and services;
  • improving the use of PPS resources.


What benefits will the implementation of CSIRE bring to end users?

End users will have free-of-charge access to their current and historical energy market information, including information about their electricity supply contracts, energy supplier information, and metering data. CSIRE will shorten selected energy market processes, in particular, the supplier change process, from the current 21 days to 1 day – which is the target. Access to metering data will enable better management of electricity consumption, which will result in lower bills. Confidence in the accuracy of billing for the sale and distribution of electricity will also be higher, as CSIRE will be a uniform, reliable and stable source of information.


What benefits will the implementation of CSIRE bring to the electricity market?

Energy suppliers will be able – only with the customer's consent – to obtain energy market information concerning the customer, including in particular metering data. This will allow them to prepare personalized offers tailored to the needs of a given customer, or to offer new services to end users (e.g., billing for consumption according to a dynamic tariff). CSIRE will standardize data collection processes and methods, thereby lowering the entry barrier for new power service providers and reducing the cost of operating in the market. Another important change will be a reduction of the number of interfaces, establishment of uniform access rules, or unambiguous division of responsibility for individual data. In the future, the CSIRE system may also be expanded to include data from additional sectors, such as gas, water and heat.


What benefits will the implementation of CSIRE bring to the PPS?

CSIRE will enable a more efficient use of resources and planning of the operation of the Polish Power System (PPS). One central energy market information database will enable the Transmission System Operator to, among other things, forecast distributed generation more accurately by having access to an up-to-date and complete database of those generators. It also provides an opportunity for future integration of retail and wholesale market processes.


When will CSIRE become operational?

From July 1, 2025


How will CSIRE acquire and share metering data?

Metering data will be obtained from smart meters, including smart meters, by Distribution System Operators (DSOs) and the Transmission System Operator (TSO), and will be transmitted to CSIRE. The CSIRE system will store and make metering data available only to authorized entities. CSIRE users, including electricity consumers, will have access to their data through the "Grid User Portal" created by OIRE.


How will the implementation of CSIRE affect the functioning of DSOs?

Distribution System Operators will have to adapt the way they execute energy market processes, their systems as well as the scope of processed metering data to the new standards. The way of sharing metering data, which DSOs will be obliged to provide to CSIRE, will also change.


How will the implementation of CSIRE affect the functioning of energy suppliers?

Energy suppliers will have to adapt the way they execute energy market processes as well as their systems to the new standards.


How will CSIRE affect the existing model of information exchange among energy market participants?

Currently, information is exchanged in a distributed and decentralized manner. Market participants such as: DSOs, TSOs, suppliers, generators, BRPs, or customers and prosumers, communicate with each other and transmit data among themselves. In practice, this means that multiple data sources and different standards are in use, and there are many different stakeholders. The solution to this problem is the implementation of a central database that will be the main place collecting and providing access to energy market information. The centralized model assumes the transfer/exchange of information only with OIRE.


Where can I find the scope of information that will be processed in CSIRE?

Full specification of the information that will be processed in CSIRE can be found in the appendix to the CSIRE Information Exchange Standards – Appendix 1, Information Scope of CSIRE Messages.


What is the legal basis for changes in the electricity market?

Act of May 20, 2021 amending the Energy Law Act and certain other acts (Dz. U. of 2021, item 1093,) and related secondary legislation (implementing acts) (regulations);


Will it be mandatory to submit data and information to CSIRE?

Yes, under the Act, all entities – including electricity consumers – participating in energy market processes will be required to submit relevant energy market information to CSIRE.


Will the use of CSIRE be free?

Using CSIRE will be free of charge for end users, DSOs and energy suppliers, among others.


Who will have access to my data and for what purpose?

The customer's data, including metering data, will be made available in accordance with the Act to the Customer itself, to DSOs – to the extent necessary for the execution of their rights and obligations, to the supplier – to the extent necessary for making settlements for electricity, and to the entity authorized by the customer – to the extent specified in the authorization.


How long will my metering data be stored in CSIRE?

According to the Act, the customer's metering data will be kept for 7 years from the date it is registered in the system. After that time, OIRE will anonymize the data, meaning that it will not be possible to attribute it to a specific customer. Storage of data will be further possible in the form of aggregated (summary) data.


Will my data be safe?

The processing of personal data at CSIRE will comply with the requirements set out in Regulation (EU) 2016/679 of the European Parliament and of the Council of April 27, 2016. (GDPR). PSE has procedures in place to protect personal data as part of the Information Security Management System. PSE has Data Protection Officer and the Personal Data Protection Section in place. The design of CSIRE will take into account the requirements arising from GDPR, in particular with regard to the principle of privacy by design and privacy by default, ensuring the security of personal data processing based on international ISO/IEC 29134:2017 standards, and ensuring individual rights for those whose data will be processed in CSIRE (e.g., the right of access to data, the right to a copy of data). Taking the above into account, the processing of personal data in CSIRE will be carried out in a secure manner and with protection of the rights of persons whose data will be processed in this system.




Who is required to send CSIRE migration data by December 31, 2023?

All entities indicated in Article 20 of the Act of May 20, 2021 amending the Energy Law Act and certain other acts (Dz. U., item 1093) are required to submit data to CSIRE. Based on the data feeds by individual entities, the initial batch for the CSIRE system will be prepared.

The obligated entities are:

  • Electricity Distribution System Operators
  • owners of equipment, plants or networks for which a Power Distribution System Operator has not been appointed
  • operators of public charging stations (the obligation will be withdrawn when an amendment to the Act on electromobility and alternative fuels enters into force)

As part of the ongoing work on amending the Energy Law Act, the expansion of the catalog of entities obliged to submit migration data to CSIRE by adding sellers (entities with a license for electricity trading) is planned.


What are the key deadlines in the migration process?

The CSIRE Implementation Plan takes into account the deadlines specified in the Act, presents the process of developing and agreeing on the documents that form the formal basis for CSIRE implementation and operation, and the process of migrating the initial data necessary to launch CSIRE.

The document will be updated and supplemented in line with the progress of project works on CSIRE implementation and legal changes.


What scope of data is subject to migration?
