ACER REMIT Reporting for Electricity Market & Electrical Battery Storage

Differences between Electricity Nominations, Electricity Transportation Contracts, and ENTSO-E Fundamental Data

Electricity Transportation Contracts

Electricity Transportation Contracts are agreements between market participants (like producers, traders, or consumers) and TSOs. These contracts define the terms and conditions for the use of the transmission network to transport electricity. Key elements include:

- Capacity Rights: Specify the right to use a certain capacity of the transmission network.
- Duration and Terms: Define the length of the contract and specific obligations and rights of the parties involved.
- Tariffs and Fees: Include information on the costs associated with the use of the transmission network.

Example: A contract between a wind farm operator and a TSO to transport electricity from the wind farm to the national grid over a year.

Electricity Nominations

Electricity Nominations refer to the schedules or plans for electricity delivery, indicating how much electricity will be transmitted over a certain period. These nominations are typically submitted by market participants to transmission system operators (TSOs) to inform them of their intended usage of the transmission network. The key aspects include:

- Timing and Quantity: Specifies the amount of electricity to be injected or withdrawn from the grid at specific times.
- Bilateral Agreements: Often related to agreements between electricity producers and consumers or between traders.
- Market Operations: Crucial for balancing supply and demand in the electricity market.

Example: A power producer might nominate 100 MWh to be delivered to a customer during a specific hour of the day.

ENTSO-E Fundamental Data

ENTSO-E Fundamental Data encompasses a wide range of basic data relevant to the electricity market, collected and published by the European Network of Transmission System Operators for Electricity (ENTSO-E). This data includes:

- Generation and Load Data: Information on electricity generation and consumption.
- Transmission System Data: Details about the capacity and usage of the transmission network.
- Market Data: Information on electricity prices, market transactions, and cross-border flows.
- Outages and Availability: Data on planned and unplanned outages of generation and transmission assets.

Example: Data on the total electricity generated by renewable sources in a specific country for a given month.

Key Differences

- Electricity Transportation Contracts deal with the legal and commercial arrangements for using the transmission network.
- Electricity Nominations are primarily concerned with the scheduling and operational plans for electricity delivery.
- ENTSO-E Fundamental Data provides a broad overview of the electricity market and system operations, including generation, consumption, and infrastructure data.

These components are crucial for ensuring transparency, market integrity, and efficient functioning of the wholesale electricity market under REMIT. For more detailed guidelines and requirements, you can refer to the ACER REMIT Manual of Procedures (MoP) on Data Reporting and other official ACER documentation.

Transactions & Fundamental Data Reporting for Electrical Battery Storage

In accordance with Article 8(5) of REMIT, market participants shall provide the Agency and NRAs with information related to the capacity and use of facilities for production, storage, consumption of electricity, including planned and unplanned unavailability of these facilities.

If the holder of the contact is able to take physical energy from the electrical battery storage, this is a contract for the supply of electricity. This is a notifiable contract within the meaning of Article 3 of the REMIT Implementing Regulation. (ACER FAQ Question 3.1.20)

For reporting transactions related to electrical battery storage under REMIT, the following message types should be used:

- Standard Contracts (REMITTable 1) – for standardized contracts
- Non-Standard Contracts (REMITTable 2) – for non-standardized contracts
- Electricity Nominations – for nominating electricity inflows and outflows related to storage activities

These message types ensure that all relevant transactions and usage data for battery storage are captured and reported in compliance with REMIT requirements. Further details can be found in the Transaction Reporting User Manual (TRUM).

Inside Information Reporting for Electrical Battery Storage

Inside information reporting under REMIT includes any unplanned outages, capacity changes, or other significant operational information that could impact the market. This requirement ensures that all market participants have access to information that could affect the supply, demand, or prices in the wholesale energy markets. This transparency helps to prevent market manipulation and insider trading.

In the ACER REMIT guidelines, there is no specific minimum size defined for battery storage facilities that must be reported. However, the general principle under REMIT is that any facility, including electrical battery storage, which can have a significant impact on the supply, demand, or prices in the wholesale energy market, must report relevant transactions and inside information.

Inside information reporting includes any unplanned outages, capacity changes, or other significant operational information that could impact the market.
