High-level Concept Clause Samples
A High-level Concept clause serves to outline the overarching principles or objectives that guide the interpretation and application of an agreement. This clause typically sets the context for the contract by summarizing the parties' intentions, the general purpose of the arrangement, or the foundational values that underpin the document. For example, it may state that the agreement is intended to foster collaboration, ensure compliance with certain standards, or promote mutual benefit. By establishing a clear conceptual framework, the clause helps ensure that the contract is interpreted consistently and that its provisions are understood in light of the parties' shared goals.
High-level Concept. In case that the frequency is different from the nominal frequency of 50 Hz, the electrical time starts deviating from the UTC. By changing the setpoint frequency, the TSO can mitigate this deviation in order to maintain synchronization of electrical time to UTC.
High-level Concept. FCR implementation The Nordic Frequency Containment Process (FCP) applies two types of Frequency Containment Reserves (FCR), which are explained below.
High-level Concept. 9.2.1 Exchange of reserve capacity
High-level Concept. 9.2.1 51BExchange of reserve capacity The exchange of reserve capacity allows TSOs to organise and to ensure the availability of reserve capacity resulting from FCR dimensioning (see chapter 6) and FRR dimensioning (see chapter 7), by relying on reserve providing units and reserve providing groups which are connected to an area operated by a different TSO. Figure 1 illustrates the exchange of 200 MW of reserve capacity (FCR, FRR or RR) from Area B to Area A. Figure 1: Exchange of reserve capacity – simple example Suppose that the dimensioning results in the need of 300 MW for Area A and 200 MW for Area B. Without the exchange of reserve capacity the respective reserve capacity has to be provided by reserve providing units or reserve providing groups connected to the Area which means that 300 MW have to be connected in Area A and 200 MW in Area B. As a result of the exchange of reserve capacity of 200 MW from Area B to Area A, 200 MW of reserve capacity needed for Area A are now located within Area B, whereas Area A still ensures in addition the availability of the full amount of its own reserve capacity. Although the geographical location of the reserve capacity is different from the dimensioning results for each area, the total amount of reserve capacity within Area A and B is still 500 MW which is equivalent to the total amount without the exchange. Table 5 shows references to the limits for exchange of FCR and FRR. Table 5: Exchange limits FCR FRR RR

High-level Concept. 9.2.1 Exchange of reserve capacity
9.2.2 Sharing of reserve capacity in general The sharing of reserve capacity allows the TSOs to organise and to ensure the availability of reserve capacity resulting from FCR dimensioning (see chapter 6) and FRR dimensioning (see chapter 7), by relying on the same reserve capacity as relied on by a different TSO. The figure below illustrates the sharing of 100 MW of reserve capacity between the TSOs of Area A and the TSOs of Area B. Suppose that the Dimensioning Rules for Area A and Area B result in the need of 300 MW FRR for Area A and 200 MW for Area B (same amounts as in Fejl! Henvisningskilde ikke fundet.). Without the sharing of reserve capacity, the TSOs of Area A and Area B have to ensure the availability of respectively 300 MW and 200 MW. However, assuming that in some cases it might be very unlikely that both TSOs need to activate the full amount reserve capacity at the same time, the TSOs of Area A and Area B can ‘share’ part of their reserve capacity. In practice this means that the TSOs of Area B can make use of e.g. 100 MW of the reserve capacity of the TSOs in Area A. Such an arrangement can be unilateral (TSOs of Area B can make use of 100 MW of the reserve capacity of the TSOs in Area A but not vice versa) or bilateral (in which case the TSOs of Area A can also access 100 MW of the reserve capacity of the TSOs in Area B). As a result, the TSOs of Area A and Area B now need to ensure the availability of 300 MW and 100 MW. The TSOs of Area A now make 100 MW of their own reserve capacity also available to the TSOs of Area B. The total amount of the reserve capacity within the system is now 400 MW, whereas it was 500 MW without the sharing agreement (leading in this example to reduction of 100 MW of reserve capacity in the total system). In contrast to the exchange of reserve capacity which only changes the geographical distribution of reserve capacity, the sharing of reserve capacity changes the total amount of active power reserves in the synchronous area, with an impact on the geographical distribution as an additional implicit effect. The sharing agreement defines priority rights to the shared reserve capacity in the situation where both TSOs have a simultaneous need. Table 4 shows references to the limits for sharing FCR and FRR.
