Entering the Balancing Market: Legal Aspects of Forming a Balancing Group

The modern Ukrainian electricity market requires businesses to maintain strict financial discipline. Due to full financial responsibility for imbalances and significant price fluctuations, traditional individual operating strategies are becoming less effective.

Joining a balancing group makes it possible to manage potential costs more effectively. However, without reliable legal safeguards, the balance responsible party risks becoming financially responsible for other participants' defaults without adequate protection.

What Is a Balancing Group and How Does the Compensation Mechanism Work?

A balancing group is a mechanism of shared responsibility among electricity market participants for imbalances. Put simply, the participants agree that the transmission system operator, NPC Ukrenergo, will assess them not individually but as a single portfolio. In other words, the imbalances of such participants are calculated collectively within the balancing group.

In the electricity market, each participant must forecast as accurately as possible how much electricity it will generate or consume. If the actual figures differ from the forecast, an imbalance occurs. The participant must then pay for that imbalance, sometimes in very substantial amounts.

This is where the practical value of a balancing group comes into play. Within the group, one participant's deviations may be partially offset by another participant's deviations. For example, one renewable energy producer may generate less electricity than expected due to weather conditions, while another producer in the same period exceeds its generation forecast. From the market's perspective, the combined position will be more balanced than if the two participants operated separately.

Consider the following example. Supplier A has an electricity deficit because its actual consumption exceeds the forecast by 10 MWh. At the same time, Generator B, which is part of the same group, has a surplus of 8 MWh. If they operated separately, Supplier A would have to purchase the deficit on the balancing market at a potentially high price, while Generator B would sell its surplus at a lower price. Within the balancing group, these volumes offset each other. As a result, the group's total imbalance to be settled with NPC Ukrenergo is only 2 MWh.

This mutual offsetting effect can reduce the group's overall imbalance costs by an average of 30 to 50%.

The central figure in this model is the Balance Responsible Party (BRP). The BRP interacts with the transmission system operator, submits schedules, receives imbalance invoices, and effectively bears the financial responsibility for the entire group.

At the same time, it is important to understand that a balancing group is not a separate legal entity. It is an association of legal entities participating in these contractual and market relationships.

What Is the Procedure for Creating a Balancing Group and How Is It Legally Structured?

The process of creating a balancing group begins when one of the participants obtains the status of a Balance Responsible Party, or BRP. To do this, the company must enter into an imbalance settlement agreement with the transmission system operator, complete registration on MMS, one of Ukrenergo's operational platforms, and comply with the Market Rules requirements regarding financial security, commercial metering, and data exchange. The BRP becomes the central participant in the future balancing group and is responsible to the settlement administrator for the imbalances of the entire group.

After that, the BRP enters into a balancing group participation agreement with the other participants, which defines:

• the procedure for joining and leaving the group;
• the mechanism for allocating imbalances;
• the financial liability of the participants;
• settlement deadlines;
• the procedure for providing forecasts;
• the terms for compensating losses.

Once the agreements have been concluded, the BRP submits information about the composition of the balancing group and the relevant participants' EIC codes to the settlement administrator, NPC Ukrenergo. The information about the composition of the balancing group is then entered into the market systems, and the balancing group begins operating as a single balancing unit within the electricity market. Thus, a balancing group functions as a contractual association of electricity market participants organized around the BRP.

Who Can Create a Balancing Group in Ukraine?

Balancing groups are most commonly created by electricity traders, suppliers, or large electricity producers, for whom electricity generation licensing and electricity supply licensing may also be relevant. This model is particularly common in the renewable energy sector, where the issue of imbalances can have critical financial consequences.

However, Ukrainian legislation does not limit the creation of a balancing group to specific categories of market participants. The main requirement is the ability to obtain the status of a Balance Responsible Party, or BRP, and comply with the requirements of the Market Rules.

This is where many companies mistakenly assume that BRP status is merely a technical formality. In reality, it represents a separate area of significant legal and financial responsibility, as mentioned above. The BRP does not simply administer the group but effectively assumes the risk associated with the imbalances of other participants. That is why, before creating a balancing group, companies usually analyze:

• the financial stability of prospective participants;
• their history of operating in the electricity market;
• the predictability of their electricity consumption or generation;
• the existence of overdue debts;
• the quality of commercial metering.

For renewable energy projects, the quality of generation forecasting is particularly important. A poor forecast from a single power plant can significantly affect the financial performance of the entire group.

What Agreements Does a Balancing Group Need to Conclude?

The fundamental document is the imbalance settlement agreement with the transmission system operator. Without it, a company cannot obtain BRP status or operate on the balancing market. However, the main legal document within the group itself is the balancing group participation agreement. It determines how the participants interact with each other and, most importantly, who ultimately bears the financial burden in problematic situations.

In practice, this agreement often becomes the source of disputes because many companies use standard templates without taking into account the specific nature of their business. For example, the agreement may contain unclear provisions regarding the mechanisms for allocating imbalances, compensation deadlines, the procedure for leaving the group, the process for covering outstanding debts, or the BRP's right to promptly exclude a problematic participant.

Problems begin when one of the participants accumulates a significant debt or suddenly worsens the accuracy of its forecasting. If the agreement does not contain effective mechanisms to protect the BRP, the financial risks may ultimately fall on the BRP.

In large balancing groups, separate financial security mechanisms are also commonly established, including guarantee payments, deposits, bank guarantees, or internal risk limits.

Requirements for Balancing Group Participants

The legislation establishes basic requirements for participants in the electricity market, but in practice, these requirements are not sufficient. Most BRPs establish their own internal control systems because the reason is clear: any mistake made by one participant can create a problem for the entire group.

That is why, before a new participant joins, the BRP usually reviews not only the company's documents but also its actual operating model. This includes analyzing its imbalance history, financial discipline, and the stability of its generation or consumption schedules. BRPs are particularly cautious about:

• new renewable energy projects with no forecasting history;
• companies with unstable electricity consumption;
• participants involved in litigation related to the electricity market;
• counterparties with a risk of default.

Large balancing groups increasingly resemble financial risk management models rather than simply an "association of participants." The legal component is therefore closely connected with financial analysis.

Real Risks for the Balance Responsible Party (BRP)

The main feature of BRP status is that it concentrates the risks of the entire group on the BRP. If one participant fails to pay for its imbalances, the transmission system operator will still require payment from the BRP. If a participant has problems with forecasting, the resulting financial impact also affects the entire group.

In practice, the BRP often becomes an internal "financial buffer" for the participants. Situations that are particularly risky include:

• the agreements do not contain clear mechanisms for rapid debt recovery;
• participants do not provide financial security;
• the BRP does not control risky exposure limits;
• there is no real-time monitoring of imbalances.

A separate risk is cash flow gaps. The BRP often has to pay the transmission system operator's invoices before receiving compensation from the group participants. It is important to remember that NPC Ukrenergo issues imbalance invoices with strict payment deadlines.

If the BRP fails to pay an invoice on time, it acquires Predefault status, which restricts its activities. If the violation is not remedied within the period established by the Market Rules, the BRP acquires Default status, resulting in the complete suspension of its operations on the market.

If your participants delay payment by even two days, you may be forced to cover the shortfall with your own funds or borrowed capital. The legal structure of the settlement process should therefore be designed to give the BRP a time buffer of at least 3 to 5 banking days.

If one of the major participants in the group becomes insolvent, the imbalance accumulated by that participant remains legally with the BRP. You may pursue the insolvent participant in court for years, but you are still required to pay the transmission system operator immediately. That is why the legal structure of a balancing group should be built not merely around organizing its operations, but primarily around a system designed to protect the BRP.

Typical Mistakes When Creating a Balancing Group

The most common mistake is using standard template agreements without adapting them to the company's own business model. Under favorable circumstances and in the absence of force majeure or bad-faith participants, this approach may work for years. However, once significant imbalances or a participant default occur, disputes may arise that cannot be properly resolved using a generic template agreement.

Another common problem is the lack of a financial security mechanism. Neglecting this tool may force the BRP to cover participants' debts with its own funds if a participant accumulates a substantial outstanding balance.

Many companies also fail to pay sufficient attention to the mechanism for a participant's exit from the group. This is a mistake because there is no way to be certain that every participant will remain reliable and that none of them will become problematic or high risk.

In the renewable energy sector, another specific mistake is underestimating forecasting risks. An inaccurate generation forecast can very quickly turn expected savings into significant financial losses.
