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 (CSIRE) 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, among others, the supplier change process. It is also a place where metering data from electricity meters (collected and transmitted to CSIRE by TSO and DSOs) are registered and shared.

 

What is energy market information?

Energy market information is:

  • 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, producers, and prosumers?

End users, producers, and prosumers 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 potential 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?

The system was launched on July 1, 2025.

The phased process for connecting individual energy companies was defined in the amendment to the Energy Law Act, which entered into force on June 11, 2025. Eligibility for connecting to CSIRE depends on the number of metering points serviced by a given DSO. The entire implementation process is scheduled to be completed by October 19, 2026.

 

How does CSIRE acquire and shares metering data?

Metering data are obtained from electricity meters, including smart meters, by Distribution System Operators (DSOs) and the Transmission System Operator (TSO), and are transmitted to CSIRE. The CSIRE system stores and makes metering data available only to authorized entities. CSIRE users, including electricity consumers, will have access to their data through the My IRE portal created by OIRE.

 

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

Distribution System Operators 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 method of sharing metering data, which DSOs are obliged to provide to CSIRE, will also change.

 

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

Energy suppliers have to adapt the way they execute energy market processes as well as their systems to the new standards. The method of obtaining metering data – provided to CSIRE by DSOs – will also change.

 

How does 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, using various forms of communication. 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 are processed in CSIRE?

Full specification of the information that are 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 April 10, 1997 – Energy Law (Journal of Laws of 2024, item 266, as amended) and related implementing acts (regulations), as well as the provisions of acts amending the Energy Law, including:

  • Act of May 20, 2021, amending the Energy Law and certain other acts (Journal of Laws, item 1093, as amended);
  • The Act of July 7, 2023, amending the Act on the Preparation and Implementation of Strategic Investments in Transmission Networks and certain other acts (Journal of Laws of 2023, item 1506);
  • The Act of July 28, 2023, amending the Energy Law and certain other acts (Journal of Laws of 2023, item 1681);
  • Act of August 17, 2023, amending the Act on Renewable Energy Sources and certain other acts (Journal of Laws of 2023, item 1762);
  • Act of May 21, 2025, amending certain acts in connection with the introduction of the Central Energy Market Information System and other acts (Journal of Laws of 2025, item 759).

 

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

Yes, in accordance with applicable regulations, all entities participating in energy market processes are required to submit relevant energy market information to CSIRE.

  

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

The customer's data, including metering data, will be made available:

  • 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 Energy Law 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 complies 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).

The processing of personal data in CSIRE is therefore carried out in a secure manner and with protection of the rights of persons whose data are processed in this system.

 

CSIRE DATA MIGRATION

 

Am I obligated to participate in the Data Migration Process?

Market participants who provide electricity transmission or distribution services or sell electricity to end users are required to participate in the Data Migration Process, in accordance with Article 20 of the Act of May 20, 2021, amending the Energy Law and certain other acts (Journal of Laws, item 1093, as amended).

 

What are the key deadlines in the migration process?
