FAQ: ACER REMIT Reporting
The concept of a market participant
ACER generally considers at least the following types of entities to be market participants under REMIT when they enter into wholesale energy market transactions:
- Energy trading companies
- Producers (electricity / gas)
- Shippers of natural gas
- Balance responsible entities
- Wholesale customers
- Final customers
- TSOs
- DSOs
- SSOs
- Investment firms
Registration of the market participant
Who has to register?
All market participants entering into reportable wholesale energy market transactions must register with the national regulatory authority (NRA) in the Member State where they are established or resident. Non-EU participants may choose their NRA. Each participant can only register with one NRA. Participants in Germany register with the Bundesnetzagentur.
How is registration carried out?
Registration is performed online via CEREMP. It may be completed by an authorized person with a valid power of attorney, typically uploaded during the registration workflow.
Which fundamental data reports may be required for a photovoltaic park?
Electricity Rights
- This report concerns rights for access to grid capacities and is generally used for larger networks or capacities.
- E.g. for a 10 MW photovoltaic park, this report is usually not required unless the park needs to acquire or transfer rights related to grid capacity.
Electricity Bids
- This report pertains to bids made on the electricity market.
- E.g. if the photovoltaic park is directly feeding into the market and placing bids, this report is required.
Electricity Total Allocation
- This report concerns the allocation of electricity and is used for distribution of generated amounts.
- E.g. if the photovoltaic park is part of a system where allocations are given (e.g., in FiT contracts or market mechanisms), this report is required.
Electricity Nominations
- This report concerns the nominated amount of electricity scheduled for delivery.
- E.g. if the photovoltaic park nominates how much electricity it will deliver, this report is required.
Electricity Configuration
- This report concerns changes in the system configuration of generation plants or networks.
- E.g. for a 10 MW photovoltaic park, this report would be required if there are changes to the setup of the park or grid infrastructure, such as during construction or major maintenance.
Electricity Generation Load
- This report concerns the generation load and should be submitted if the amount of electricity generated changes or if there is a significant deviation from the expected load.
- E.g. for a 10 MW photovoltaic park, this report is required if there is a significant change in the generated electricity, such as due to unexpected outages or changes in solar conditions.
Electricity Outage
- This report concerns outages of power generation plants or networks.
- E.g. for a 10 MW photovoltaic park, this report is required if there is an outage of the facility (e.g., technical failure or unexpected shutdown of generation).
Electricity Publications
- This report concerns the publication of market-relevant information.
- E.g. for a 10 MW photovoltaic park, this report may be required if the park publishes market-related data (e.g., publicly available information about production).
What is the scope of contracts reportable at request of the Agency?
According to Article 3(1) of Commission Implementing Regulation (EU) No 1348/2014, the Agency may request market participants to report certain contracts and transaction details, unless concluded on organized marketplaces:
-
- Intragroup contracts.
- Contracts for physical delivery of electricity produced by a single unit or combined units with a capacity ≤ 10 MW.
- Contracts for physical delivery of natural gas from a single production facility with a capacity ≤ 20 MW.
- Contracts for balancing services in electricity and natural gas.
Market participants engaging only in transactions for contracts in points (ii) and (iii) (≤ 10 MW for electricity, ≤ 20 MW for gas) are not required to register with the NRA under Article 9(1) of REMIT.
Acronyms
MMBtu
1 Million British Thermal Units – a thermal unit of measurement for natural gas. Thermal units differ from pure volumetric units because they assume energy content. Gas that is more liquids-rich may have higher Btu content within the same volume compared to dry gas.
