Requirements for Generators Intro
“…a network code which lays down the requirements for grid
connection of power generating facilities, including
synchronous power generating modules, power park modules and
offshore power park modules, to the interconnected system”
“It, therefore, helps to ensure fair conditions of competition in the
internal electricity market, to ensure system security and the
integration of renewable electricity sources, and to facilitate
Union-wide trade in electricity”
It also lays down the obligations for ensuring that system
operators make appropriate use of the power generating
facilities’ capabilities in a transparent and non-discriminatory
manner to provide a level playing field throughout the Union”
Article 1, 2015 draft RfG

Introduction to RfG “banding”
Technical requirements are applied to generators based
on four MW capacity/connection voltage thresholds
Broadly, Type A-B requirements are more akin to a
manufacturing standard. Types C-D are similar to
existing GB Grid Code requirements (i.e. real-time)
TSOs need to define thresholds – justified by a Cost-
Benefit analysis; ratified via industry consultation and
Authority approval

Introduction to Banding – Type A
A basic level necessary to ensure capability of generation over
operational ranges with limited automated response and minimal
system operator control.
Type A ensure that there is no large-scale loss of generation over
system operational ranges, minimising critical events, and include
requirements necessary for widespread intervention during system-
critical events.
Overview of technical requirements:
Operation across a range of frequencies
Limits on active power output over frequency range
Rate of change of frequency settings applied (likely to be at least 1Hz/sec)
Logic interface (input port) to cease active power output within 5 secs
11
Introduction to Banding – Type B
Type B provides for a wider range of automated dynamic response,
with greater resilience to more specific operational events.
They ensure an automated response to alleviate and maximise
dynamic generation response to system events.
Overview of technical requirements
Type A, plus…
Ability to automatically reduce power on instruction
Control schemes, protection and metering
Fault Ride Through requirements
Ability to reconnect
Reactive capability
Reactive current injection

Joint GCRP/DCRP RfG Workgroup
Direction from all parties to use existing code modification
processes as far as possible
Terms of reference for workgroup circulated to all GB
code panels for feedback;
Approved by GCRP and DCRP in late 2013
Discussed at JESG, in DECC/Ofgem forums
Workgroup (“GC0048”) formed in Jan 2014; 10 meetings
since
Model for other connection codes (HVDC/DCC)?
