COMPLIANCE LEVELS

1 ANALYSING PRINCIPLES

1.1 INTRODUCTION

This Annex 1 of the Compliance Oversight Report 2012 contains detailed results of the analysis of the

explanations for the declared compliance level. All standards from the RGCE OH policy 4 which were

assessable had a mandatory explanation request for the declared compliance level. The framework

of the self-assessment process is described in chapters 2 and 3 of the COR 2012 main document.

Each standard has a credibility analysis table which presents the evaluation of the explanation given

by all TSOs related to the standard. The data used for this analysis was provided by the RGCE TSOs

before 8 June 2012 via the RGCE compliance self assessment web questionnaire 2012 system.

1.2 CRITERIA FOR SAQ 2012 ANSWER ASSESSMENT

Assessment teams will follow same principles as 2011 (Chapter 1.3.) with following additions:

o Mismatches between neighbouring TSOs will be analysed and may be an additional input to evaluate credibility of the compliance declaration explanation. The weight of mismatches depends on the standard and TSOs explanations and rely assessment team’s experience and expertise.

o In case two TSOs declare two different compliance levels on a multilateral standard the lower declaration is assumed more credible as rule of thumb if no additional information is in the compliance level explanation

1.3 STRUCTURE OF THE TABLES

The declared compliance level:

o FC = fully compliant (this implies that no improvement/mitigation plan is needed)

o SC = sufficiently compliant (an improvement plan with a deadline to reach full compliance is necessary)

o NC = non-compliant (a mitigation plan with a deadline to remove non-compliance is obligatory)

o N/A = not applicable

The credibility grade for the explanation for the compliance level declaration:

o Credible (CR, Green), good and precise answer

o Some doubts (SD, Yellow), answer is a little bit off topic, inadequate, not precise (or

contains mismatches with neighbours without proper explanation, refer to chapter

1.2. bullet points)

o Not Plausible (NP, Red), missing answer or completely off topic

Comment 2

Capacity assessment is regularly performed on a Regional basis based on common grid model providing the most probable

topology (e.g. planned outages) and flow pattern (e.g. exchanges, load and generation injections).

Existing procedures are in line with Policy 3: during all capacity assessment processes (Y, M, D-2, D-1, D) the n-1 security

principles are respected and verified by calculations; the list of critical branches and remedial actions are shared at Regional

level with neighboring TSOs.

High level of regional coordination is sometimes achieved by the support Central Allocation Offices (e.g. CAO, SG SEE CMMI,

CWE ATC based Market Coupling, etc.)

In the case of ME-CGES, level NC should have been declared: the chosen compliance level does not reflect the fact there is no

Network model

Each TSO provides to the EH-ftp server a forecasted load flow data set of its grid, with the whole, detailed network model related to the transmission grid, i.e. a real model (no equivalents) of at least all elements at ≥ 220kV level like bus bar couplers, nodes, lines, transformers, nodes’ load and injections. Equivalent or real lines and transformers can be used to represent networks of lower voltages, in case they influence the 750kV, 380 kV or 220 kV level significantly.

Data collection

Each TSO collects DACF files from the EH-ftp server and constructs a network model (i.e. the DACF merging process) that represents the most probable state of the forecast time. That model can include all ENTSO-E networks, but a TSO can also disregard the data sets of TSOs whose influence on its network is deemed negligible. This process can be done in a centralized way (organized by any TSO that volunteered). Alternatively this process can be done in a centralized way by a TSO, a regional group or a TSO initiative.
