Central Energy Market Information System – A Change in the Energy Market. What Does the Introduction of CSIRE Mean?

Central Energy Market Information System – What Is It and What Are Its Objectives?

The Central Energy Market Information System (CSIRE) is a nationwide, publicly accessible, and free-of-charge IT system that connects all participants in the energy market. These include energy suppliers, grid operators, energy balancing entities, metering service providers, and ultimately end users, such as businesses. The primary task of CSIRE is to create a centralized, comprehensive database that will serve as a catalyst for economic development by:

• enabling energy suppliers to offer personalized offers to consumers,

• introducing dynamic tariffs based on the analysis of historical electricity consumption and production profiles.

According to representatives of the Ministry of Climate and Environment, the implementation of CSIRE will create many jobs and improve the business climate, particularly in the SME sector. The main objectives of introducing CSIRE also include:

• standardizing and accelerating processes in the energy market such as metering, billing, and access to information,

• improving competitiveness by creating standardized conditions for data exchange,

• facilitating prosumer engagement through simplified access to information and personalized offers,

• increasing data security.

CSIRE – What Is It? Explanation of the System's Key Assumptions

The data fed into CSIRE will primarily come from remotely read meters. The installation and replacement of these meters are the responsibility of the distribution system operator, who bears the cost. This means that prosumers will not incur any costs related to the transformation of the Polish energy sector. Using the CSIRE system will be completely free for end users, energy suppliers, and DSOs.

According to the Energy Law Act, the creation and coordination of the Central Energy Market Information System falls under the responsibility of the Energy Market Information Operator (OIRE). This role has been assigned to the company Polskie Sieci Elektroenergetyczne S.A. (PSE). The Energy Market Information Operator is responsible for:

• managing and administering CSIRE,

• supporting energy market processes,

• processing energy market information,

• developing and updating CSIRE information exchange standards,

• providing authorized users with access to the collected information.

It is worth noting that PSE fulfills statutory tasks but is not physically responsible for developing the CSIRE infrastructure. These responsibilities were entrusted to a consortium of foreign companies co-creating the Canadian IT consulting firm Consultants to Government and Industry Incorporated.

From a global perspective, CSIRE aims to reduce electricity costs and simplify the functioning of the power market. This is particularly important for energy-intensive sectors such as manufacturing and heavy industry, but also for vulnerable consumers, including end users for whom even small price fluctuations can have a significant impact.

CSIRE – When Will It Be Implemented and How Will It Affect Consumers?

CSIRE is being rolled out in stages. On July 1, 2025, the system entered into force in its "technical variant." This marked the first implementation window when entities could voluntarily join CSIRE. The next implementation windows will open on October 1, 2025, and March 1 and July 1, 2026. The final mandatory deadline for all entities that did not join in earlier windows is October 19, 2026. It is expected that the first windows will be used by modern entities with IT systems capable of full integration with CSIRE.

Importantly, entities whose networks cover no more than 100,000 Energy Consumption Points may voluntarily choose their implementation window. This flexibility is crucial, as it allows each market participant to assess their readiness to join the system.

The impact of CSIRE on system users can be assessed from the perspective of specific groups:

• The National Power System (KSE) and Power System Operators benefit from improved efficiency of resource usage in KSE, including better alignment of energy consumption with production, especially from renewables. For them, CSIRE also means integration of retail and system market processes and improved quality of measurement data. The available data is also standardized and aggregated, making it easier to use.

• End users, including prosumers, gain primarily:

  • free access to their own metering data,

  • easier switching of energy suppliers,

  • the ability to verify the amount of electricity fed into and drawn from the grid,

  • the option to share their metering data to receive better offers,

  • easier activation of backup supply,

  • enhanced data protection in line with GDPR.

Combined with renewable energy technologies such as photovoltaics and heat pumps, energy management will become even simpler and more cost-effective.

Other participants in the electricity market also benefit from CSIRE. The creation of a single access point for market information lowers the entry barrier for new entities. With CSIRE's efficient data processing, it is easier to develop new services and tailor them to consumer needs (including personalized offers upon consent). Retail market processes also become more transparent, reducing the risk of service errors.

CSIRE 2025 – What Changes Await the Energy Market?

Undoubtedly, the introduction of CSIRE is a groundbreaking step, yet a necessary one for the development of the Polish energy sector. It is a move toward implementing the Energy 2.0 concept—a decentralized network based on smart energy accounting, distributed generation, and smart grids. Thanks to modern technologies, it is possible to deliver flexible solutions that enhance energy security.

The unification of data collection standards also means that in the near future, many new entities are likely to enter the energy services market. This growing competition is expected to lower prices and improve customer service levels.

The legislation introducing CSIRE is not the only change. Adjustments will also affect virtual prosumers, electricity generation licenses, and how energy consumption is calculated and invoiced for customers.

The full effects of CSIRE implementation will become visible next year. Only then will all energy market participants be subject to the new regulations, and the system will be able to demonstrate its full potential.
