Type B Power Generating Module
European Union Electricity Market Glossary

 


 

 

Pursuant to the Network Code on requirements for grid connection of generators (NC RfG), type B category of Power Generating Module has Connection Point below 110 kV and its maximum capacity is at or above a threshold specified by the relevant Transmission System Operator (TSO) and approved by the competent regulatory authority.

 

However, this threshold shall not be above the limit for type B Power Generating Modules as in the Table:

Continental Europe

1 MW

Great Britain

1 MW

Nordic

1.5 MW

Ireland and Northern Ireland 

0.1 MW

Baltic

0.5 MW

 

Pursuant to the Recital 12 of the NC RfG the requirements applicable to type B Power Generating Modules are designed to provide for a wider range of automated dynamic response with greater resilience to operational events, in order to ensure the use of this dynamic response, and a higher level of system operator control and information to utilise those capabilities.

 

They ensure an automated response to mitigate the impact of, and maximise dynamic generation response to, system events. 

 

 

 

Recitals 9, 10, 12 of the Network Code on requirements for grid connection of generators (NC RfG) 

 

(9) The significance of power generating modules should be based on their size and their effect on the overall system. Synchronous machines should be classed on the machine size and include all the components of a generating facility that normally run indivisibly, such as separate alternators driven by the separate gas and steam turbines of a single combined cycle gas turbine installation. For a facility including several such combined cycle gas turbine installations, each should be assessed on its size, and not on the whole capacity of the facility. Asynchronous machines, where they are collected together to form an economic unit and where they have a single connection point should be assessed on their aggregated capacity.

 

(10) In view of the different voltage level at which generators are connected and their maximum generating capacity, this Regulation should make a distinction between different types of generators by establishing different levels of requirements. This Regulation does not set the rules to determine the voltage level of the connection point to which the power generating module shall be connected.

 

(12) The requirements applicable to type B power generating modules should provide for a wider range of automated dynamic response with greater resilience to operational events, in order to ensure the use of this dynamic response, and a higher level of system operator control and information to utilise those capabilities. They ensure an automated response to mitigate the impact of, and maximise dynamic generation response to, system events.

 

 

 

 

Article 3 of the Network Code on requirements for grid connection of generators (NC RfG)

Scope of application

 

1. The connection requirements set out in this Regulation shall apply to new power generating modules which are considered significant in accordance with Article 5, unless otherwise provided.

 

The relevant system operator shall refuse to allow the connection of a power generating module which does not comply with the requirements set out in this Regulation and which is not covered by a derogation granted by the regulatory authority pursuant to Article 60. The relevant system operator shall communicate such refusal, by means of a reasoned statement in writing, to the power generating facility owner and, unless specified otherwise by the regulatory authority, to the regulatory authority.

 

2. This Regulation shall not apply to:

 

(a) power generating modules connected to the transmission system and distribution systems or to parts of the transmission system, or distribution systems, of a Member State of which the systems not operated synchronously with either the Continental Europe, Great Britain, Nordic, Ireland and Northern Ireland or Baltic synchronous area;

 

(b) power generating modules that were installed to provide back-up power and operate in parallel with the system for less than five minutes per calendar month while the system is in normal system state. Parallel operation during maintenance or commissioning tests of that power generating module shall not count towards the five minute limit;

 

(c) power generating modules that do not have a permanent connection point and are used by the system operators to temporarily provide power when normal system capacity is partly or completely unavailable;

 

(d) storage devices except for pump-storage power generating modules in accordance with paragraph 2 of Article 6.

 

 

 

 

Article 5 of the Network Code on requirements for grid connection of generators (NC RfG) 

Determination of significance

 

1. The power generating modules shall comply with the requirements on the basis of the voltage level of their connection point and their maximum capacity according to the categories set out in paragraph 2.

 

2. Power generating modules within the following categories shall be considered as significant:

 

(a) connection point below 110 kV and maximum capacity of 0.8 kW or more (type A);

 

(b) connection point below 110 kV and maximum capacity at or above a threshold proposed by each relevant TSO in accordance with the procedure laid out in paragraph 3 (type B). This threshold shall not be above the limits for type B power generating modules contained in Table 1;

 

(c) connection point below 110 kV and maximum capacity at or above a threshold specified by each relevant TSO in accordance with paragraph 3 (type C). This threshold shall not be above the limits for type C power generating modules contained in Table 1; or

 

(d) connection point at 110 kV or above (type D). A power generating module is also of type D if its connection point is below 110 kV and its maximum capacity is at or above a threshold specified in accordance with paragraph 3. This threshold shall not be above the limit for type D power generating modules contained in Table 1.

Table 1: Limits for thresholds for type B, C and D power generating modules

 

3. Proposals for maximum capacity thresholds for types B, C and D power generating modules shall be subject to approval by the competent regulatory authority. In forming proposals the relevant TSO shall coordinate with adjacent TSOs and DSOs and shall conduct a public consultation in accordance with Article 10. A proposal by the relevant TSO to change the thresholds shall not be made sooner than three years after the previous proposal.

 

4. Power generating facility owners shall assist this process and provide data as requested by the relevant TSO.

 

5. If, as a result of modification of the thresholds, a power generating module qualifies under a different type, the procedure laid down in paragraph 3 of Article 4 concerning existing power generating modules shall apply before compliance with the requirements for the new type is required.

 

 

 


 

 

 

Article 45(2) of the Network Code on Network Operation

 

Each SGU which is a power generating facility owner of a type B or a type C power generating module connected to the transmission system shall provide the TSO with at least the following data:

 

(a) general data of the power generating module, including installed capacity and primary energy source;

 

(b) data for short-circuit calculation;

 

(c) FCR data according to the definition and requirements of the Article 173 for power generating modules offering or providing that service; (d) FRR data for power generating modules that offer or provide that service;

 

(e) RR data for power generating modules that offer or provide that service;

 

(f) protection data;

 

(g) reactive power control capability;

 

(h) data necessary for determining the costs of remedial actions in accordance with Article 78(1)(b). Where a TSO makes use of market based mechanisms in line with Article 4 (2) d), the provision of prices to be paid by the TSO shall be sufficient;

 

(i) data necessary for performing dynamic stability assessment according to Article 38.
